Structure principle of board-to-board connector The basic structural parts of the board-to-board connector are as follows: contacts, insulators, shells, and accessories contacts are the core parts of the connector to complete the electrical connection function. Generally, the contact pair is composed of positive contacts and negative contacts, and the electrical connection is completed through the insertion of Yin and Yang contacts. The shape of the positive contact is cylindrical (round pin), square column (square pin) or flat (insert), and it is a rigid part. Positive contacts are generally made of brass or phosphor bronze. The contact part is the jack, which is the key part of the contact pair. It relies on the elastic deformation of the elastic structure when inserting the pin and generates the elastic force to form close contact with the positive contact part to complete the connection. There are many types of jack structures, such as cylinder type (split slot, reduced mouth), tuning fork type, cantilever beam type (longitudinal slot), folded type (longitudinal slot, figure 9), box shape (square jack) and hyperbolic wire spring jack. The insulator, also known as the base or mounting plate, is used to arrange the contacts in the desired position and spacing, and to ensure insulation between the contacts and between the contacts and the housing. Good insulation resistance, voltage resistance and machinability are the basic requirements for selecting insulating materials for processing into insulators. The housing, also known as the housing, is the outer cover of the board-to-board connector, which provides mechanical protection for the internal insulation mounting plate and pin, and provides alignment of the plug and socket when inserted, thereby fixing the board-to-board connector to the device. Accessories Accessories include structural accessories and installation accessories. Structural accessories such as fasteners, positioning keys, positioning pins, guide pins, connecting rings, cable clamps, sealing rings, gaskets, etc. Mounting accessories such as screws, nuts, screws, spring rings, etc. Most accessories have standard parts and universal parts.

Basic performance of board-to-board connectors The basic performance of board-to-board connectors can be divided into three categories: mechanical performance, electrical performance and environmental performance. 1.Mechanical properties As far as the connection function is concerned, the insertion and withdrawal force is an important mechanical property. Inserting and pulling force is divided into inserting force and pulling force (pulling force is also called separation force), and the requirements of the two are different. In the relevant standards, there are greater insertion force and minimum separation force provisions, which indicates that from the point of view of use, the insertion force should be small (so that there is a low insertion force LIF and no insertion force ZIF structure), and if the separation force is too small, it will affect the reliability of contact. Another important mechanical property is the mechanical life of the board-to-board connector. Mechanical life is actually a durability index, which is called mechanical operation in the national standard GB5095. It is based on one insertion and one withdrawal as a cycle, and whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and withdrawal cycle is used as a basis for evaluation. The insertion force and mechanical life of the board-to-board connector are related to the contact structure (positive pressure) and the coating quality (sliding friction coefficient) of the contact part and the dimensional accuracy (alignment degree) of the contact part. 2.Electrical performance mainly includes contact resistance, insulation resistance, current and electrical strength. Contact resistance: A high-quality electrical connector should have a low and stable contact resistance. Connectors have contact resistance ranging from a few milliohm to tens of milliohm. Insulation resistance: A measure of the insulation performance between electrical connector contacts and between contacts and the housing, in the order of hundreds to thousands of megohm. Electrical strength or voltage resistance: The ability to withstand the rated test voltage between the connector contacts or between the contacts and the housing depends on the gap between the circuits (that is, the distance between the contacts and the creepage distance) and the insulation material used in the connector.

What do you need to pay attention to when storing board-to-board connectors? The insulation inspection rules of the board-to-board connector: the same type of insulation material produced by the qualified supplier, the product performance is stable (no quality problems in one year and returned), and every 5 tons of sampling inspection. For the new insulation material or the insulation material or sample of the qualified supplier or the supplier of the second supply, the second sample should be sampled for type test, and the subsequent five deliveries should be sampled, and after passing, it can be converted to separate batch sampling. If the insulation material is found unqualified at one time, it shall be sampled according to the provisions of the first batch of supplies. Each batch of insulation materials must be accompanied by the supplier's material warranty or test report. Sampling method: 2 bags or more per lot. The test items are tensile strength, elongation at break, dielectric strength, volume resistivity, 80℃ volume resistivity, oxygen index and density. The performance that cannot be tested shall be accepted according to the manufacturer's test report or warranty. Packaging insulation material with plastic film bag, external PP woven fabric/kraft paper composite packaging, each bag net weight 25±0.2kg, but no negative deviation per ton. Board to board connector insulation material packaging must indicate: manufacturer name, material model and name, production date, net weight and product certificate and other marks. Electronic wire connector insulation material into the factory, should be accompanied by the manufacturer's quality guarantee certificate or quality inspection report. When supplying, the manufacturer must attach the type test report of the statutory inspection department. For normal supply, the manufacturer must provide the type test report of the statutory inspection department every two years. Transport board to board wire connector insulation material should not be exposed to the sun, rain, packaging should not be damaged. Storage board to board wire connector insulation material should be stored in a clean, cool, dry, ventilated warehouse. The storage period is 12 months from the production date.

Edge Connectors Selection Guide Card Edge Connectors Definition Card edge connectors (also called edge card connectors) are embedded devices that mate with the edges of single-sided or double-sided printed circuit boards (PCBs) in order to provide an external electrical connection. Industry standards define power specifications such as voltage levels, power pin placements, and power requirements. For example, PICMG 1.0/1.2 standards define the power specifications for peripheral component interconnect (PCI) and industry standard architecture (ISA) buses. Contacts The contacts are made of metal and are plated with a thin, metallic coating that improves conductivity and prevents rust and corrosion. Plating materials include: Gold Copper Nickel Silver Edge Card Connector Contacts are housed in a termination assembly that is usually made of plastic. Card edge connectors are used widely in personal computers (PCs) and, depending on their components, are suitable for some lead-free applications and compliant with RoHS. Rows Typically, card edge connectors are available with one or two rows of contacts. Contact Pitch The distance between pins, can range from as small as 0.0197'' or 0.5 mm to as large as 0.111'' or 2.84 mm. Geometry There are straight and right angle card edge connectors. These distinctions simply refer to the way the card edge connector is bent. Edge Card Connectors Terminations Crimping compresses or deforms a contact wire barrel around a conductor. Wire wrapping requires the use of a special tool to wrap a stripped or unstripped wire around a terminal post that contains a series of sharp edges. Insulation displacement connectors (IDCs) slice through the cable insulation to make a connection. Electrical connection is made when an insulated conductor is forced into a restrictive slot in the connection part of a contact, during which time the insulation is displaced, and the bare wire engages the sides of the slot. IDC card edge connectors are mass termination connectors for flat cables that displace the conductor insulation to complete termination. They eliminate the need to strip insulation. Printed circuit board (PCB) card edge connectors (often referred to as solder or solder pin connector), termination of the electrical connection is made by soldering wires or pins onto a printed circuit board. With solder cup terminations, soldering the connector onto the mounting location creates an electrical connection. Other termination methods also include cage clamps, screws, lugs, and quick-connect tabs. Performance Specifications Includes the following; number of contacts, voltage rating, current rating, contact resistance, insulation resistance, dielectric withstanding voltage, and operating temperature.Edge Connectors Information The voltage rating is the maximum operating voltage. The current rating is the maximum recommended continuous flow of electrical current. Contact resistance measures the electrical resistance of mated contacts that are assembled in a connector for typical service use. Insulation resistance is the electric resistance between two conductors separated by an insulating material. Dielectric withstanding voltage is the maximum potential gradient that a dielectric material can withstand without failure. Operating temperature is a full-required range. For specific performance specifications, contact one of the card edge connector manufacturers.

What is a Berg Strip - Types & Applications What is a pin header/Berg Strip? A pin header, or strip header, is a male connector with one or two rows of metal pins attached to a plastic base. Pin headers with more than two rows are available from some manufacturers. The pins are spaced in uniform intervals (commonly 2.54 mm or 0.1 inch apart) but many spacings are available depending on the application. The female counterpart is sometimes referred to as a female socket header. The original pin header was manufactured by Berg Electronics Corporation (now part of Amphenol) and, as a result, pin headers are sometimes called Berg connectors. Today, they are manufactured by many companies. Pin headers are typically through-hole devices (THD). That is, the pins are inserted through holes drilled in the PCB and soldered on the opposite side. However, some headers are surface mount devices (SMD). In this case, the pins are bent 90° and mounted (soldered) directly to the surface of the PCB. Headers can be straight (vertical) or right-angle (to connect two PCBs horizontally). Berg Strip is a commonly found connector in all kind of circuit boards. It is also called as Berg Stick because of its stick like structure. The Berg Strip is very light and compact and it can be easily assembled to a circuit board. One of the main features of the Berg Strip is that, unlike other connector a designer can modify the connector module as per his imagination. The Burg Strip can be easily cut off into pieces having required pin numbers, and then the pieces can be arranged in a single row or in a row and column manner. This freedom makes the Berg Strip all-time favorite of the circuit designers. Berg Strip Types Berg strips are available in two main forms namely male and female connectors, and each has a predetermined number of pins. The designer then removes all but the required pins and links them to the circuit board. What are the main application areas of pin headers/strip header? Pin header is commonly applied to the connection of PCB boards. The main function is to connect the blocked or isolated circuits and transmit current and signal. It is primarily used in devices inside, not as a connector in external.

Board Mount Connectors Guide Board mount connectors or circuit board connectors are connectors that can be used as components embedded on a computer board. The boards can be customized to meet the user application. Applications Board mount connectors differ in name based on their specific applications. Applications include: Board-to-board connectors are used to connect printed circuit boards (PCBs). Each terminal connects to a PCB. Wire-to-board connectors are used to interconnect PCBs by using connectors attached to wires. Board-to-wire connectors are used to interconnect PCBs by using connectors attached to wires. Edge connectors, also known as edge card connectors, are edge-on printed circuit board connectors for single or double-sided PCBs. There are many different connectors available to suit a wide variety of applications. Some connectors can be used to connect audio or USB wires to the circuit boards Connector Row Types Board mount connectors use pins to connect between boards. The pins are available in a number of different row options. Single row (SIL) Double row (DIL) Triple row Quad row Pins are also available in different orientations such as horizontal (right-angle) or vertical (straight) with respect to the in surface mount. Performance Criteria Impedance is the opposition that an electrical circuit presents to the passage of an alternating current when a voltage is applied. Voltage rating is the normal voltage to be applied to an electrical device to provide for proper operation. Current rating is the maximum, recommended, continuous flow of electrical current. Frequency range is the number of complete cycles through which the connector is designed to function according to the design. Number of contacts is the number of conductive elements that mate with a corresponding element to provide an electrical path. Contact size, also referred to as termination size, is the maximum diameter wire the connector can accommodate. Insertion loss(id dB) is the total RF power transmission loss resulting from the insertion of a device in a transmission line. Voltage standing wave ratio (VSWR) is the ration expressing the amount of reflected energy at the input device. Operating temperature the range of ambient operating temperature.

What are Floating Type Connectors? It has a structure in which an insulator housing, colored green in the figure on the right, of a mated pair of connectors is like floating. It is impossible to mate general rigid connectors if they are mounted out of precise alignment, but is possible with the floating type connectors. Even if connectors are mounted out of alignment, it is possible for a floating type connector (colored green) to move in the floating space to mate to the counterpart connector properly. Thus the connectors absorb the positional deviation on boards and positional deviation generated in installing boards on which the connectors are mounted to the customers' units. Advantages in using them It is possible to use plural pairs of connectors on a single printed circuit board, The degree of freedom in component layout and in circuit design increases, The stress applied to the solder joints decreases to suppress solder cracks.

What Is Floating? board-to-board floating connectors are electromechanical interconnects that can absorb misalignments in the "X", "Y", and "Z" axes. Unlike traditional connectors, these connectors have a unique design that suspends the mating interface above the PCB using bent terminals that provide elasticity. This elasticity is crucial in providing several advantages, including improved misalignment tolerance and greater reliability in electronic connections. floating technology offers misalignment correction and vibration protection while reducing stress to soldering joints and contact area. How It Works Increasing Tolerance & Reliability Floating board to board connections boast tolerance compensation of up to 1 mm over X, Y and Z axes. This facilitates the process of joining PCBs in the event of misalignment or blind joining. The reliability of the connection systems enable a secure usage, even under challenging ambient conditions, offering a space-saving concept. Decreasing Stress Moreover, the impacts of vibrations and shocks are effectively mitigated, while the sensitive contact surfaces are also protected against mechanical stress and fretting corrosion. Suspended mating contacts inside the plug and socket; absorb vibration and also prevent solder cracks from mating miss-alignment.

Complete Guide to Selecting Board-to-Board Connectors Types of Board-to-Board Connectors Board-to-board connectors come in a variety of shapes and sizes to give a modular feel to a multi-board PCB system. There are many types of common board connectors, and different vendors have their own product lines that fall generally into one of the categories listed below: Pin headers: Most designers are familiar with the 1-row or 2-row pin header arrangement with 1 mm pitch. There are variations on this style, including stacked pin headers. Pin headers can be shrouded and keyed (even multi-keyed) to guarantee pinouts match when boards are connected. Mezzanine connectors: This type of board-to-board connector joins two parallel printed circuit boards in a stacked configuration. There are many mezzanine connector styles. Note that a pin header can be used as a mezzanine connector. Edge card connectors: This style connector is most commonly known for its use in RAM sticks and COMs/SoMs. Really, it can be used for any board-to-board connection along a board edge, whether with a custom or standardized pinout. Backplane connectors: This type of connector deserves its own category, both due to its need to accommodate high data rates and very rugged construction. Standardized connectors: Some connectors may be developed to meet very specific industry standards beyond edge connector styles for add-in cards. Standards organizations that have defined specific connector styles include VITA (for backplanes), PCI-SIG (PCIe cards), IEEE (e.g., 1386 standard for mezzanine), JTAG, PC/104 (square-post pin headers), and others. Selecting Board-to-Board Connectors Now we can look at some of the points to consider when selecting board-to-board connectors. First, let`s look at some specifications, then we can think about the advantages of different connector styles. Board-to-Board Connector Specifications Board-to-board connectors have some electrical specifications that should be considered beyond just the connector style: Pitch and pin count: Unless you`re designing to a specific application, or you need high speed/high frequency or high current, you`ll probably start by looking at the pitch/pin count required in the connector. With low power and low speed signaling, just about every connector can handle your power requirements while ensuring signal integrity. Power handling: This is normally quoted as current at a specific voltage per pin. Most connectors can handle a few Amps at typical application voltages. Make sure to check the voltage as it is common to supply both power and data through a cable; you`ll want to make sure your power does not exceed the voltage rating. Governing standard: Any industry standards on connectors can govern form factor (some examples are discussed above), or they can cover testing and application specifications. Make sure to check these to ensure your connector style will be compliant. Environmental ratings: Specifications include power variations with humidity cycling, exposure to gases, and testing at high temperature. This gives you a good idea of where the connector can be used to ensure reliability. Data rate/frequency limit: For high speed data channels, you`ll see a recommended data rate limit, which the vendor will determine through extensive testing. Data rate limits are just a recommendation, and you might be able to get past these in your system. Be sure to test your system thoroughly if you plan to violate a data rate/frequency specification. Mechanical specifications: High-quality board-to-board connector datasheets may include some data on mechanical shock, vibration, pulling force, or other specs that help a designer understand ruggedness. Note that these may be listed as test results meant to comply with some industry standard.

Board-to-Board Connectors Board-to-board (BTB) connectors are used to accurately interconnect printed circuit boards (PCBs) in a stackable manner. They can accommodate various types of PCB orientations, relative distances, and space constraints to allow for design flexibility. In addition, multiple materials, plating finishes, and pitches are available to meet electrical and mechanical specifications. Depending on the purpose of the interconnect, connectors are further offered as high-speed, floating, or power. To achieve the desired performance, all the above should be considered when designing an interconnect system. Board-to-Board Connector Types Pin Headers Pin headers (male) and female headers (socket) are used as a set. A male pin header consists of one or more rows of metal pins molded into a plastic base. Due to their simplicity, male pin headers are the most cost-effective. Female Headers Female headers are the sockets that male headers fit into. These connectors complete the design by allowing the PCBs to be easily connected and easily replaced should either of the headers become damaged. Box Headers Box header connectors are featured with a plastic shroud around the header. This helps guide the connectors during the mating process to avoid mating errors. High-Speed Connectors High-Speed Connectors are specifically designed with robust terminals and high-temperature resistance plastic to be used in industrial applications that require high-speed transmission. The unique contact structure allows it to maintain a steady impedance profile, which ultimately minimizes both the noise and signal loss over the connectivity, with a potential secure data transmission of up to 4Gbps.

DIN 41612 Connector The DIN 41612 connector has been and remains a mainstay connector for the electronics industry connecting cards to cable forms and other boards. The DIN 41612 connector is an industry standard connector widely for connecting boards, modules to another board such as a motherboard in a system. The connector conforms tot he DIN 41612 standard - DIN is the Deutsches Institut für Normung i.e. the German Institute for Standardisation. In view of the popularity of the connector and its worldwide usage, the standard has been adopted by other bodies and may be referred to as IEC 60603-2 and EN 60603-2. Despite this adoption, the connector is still known as the DIN 41612 connector. The DIN 41612 connector finds particular applications in systems that have an open architecture where cards, modules and rack systems may be obtained from a variety of manufacturers and suppliers. For this to be able to work, the various elements from different manufacturers must be able connect reliably, and for this a standard connector is required. The DIN 41612 connector is widely used in systems from VME bus to VXI Bus, Multibus, Futurebus and many more. It is used for many Eurocard applications. For the test and instrumentation business it is used in PXI. What is the DIN 41612 connector: the basics The DIN 41612 connector is a high pin-count connector suitable for providing connections from cards to motherboards in bus based systems. The connectors have contacts arranged in rows, typically one two or three, with two and three being the most common. These rows are labelled, a, b, and c, for example a pin may be numbered 21a, or 22b, etc., dependent upon the position and the row. Typically the rows have 16 or 32 contacts per row allowing permutations of 16, 32, 48, 64 or 96 contacts. The pins are on a 0.1 inch spacing pitch (2.54 mm). The insertion and removal force are defined and there are three durability grades that are available. To aid construction of motherboards and the like, the female DIN 41612 connectors have press fit contacts options available rather than solder pin contacts. This helps avoid thermal shock to the backplane during manufacture. DIN 41612 connector types There are several different types of DIN 41612 connector that are referred to within the data sheets. These include Types B, C, D, F, M, Q and R. There are also the standard DIN sizes as well as half, third, and expanded sizes to meet all the requirements that are submitted by various equipment manufacturers. DIN 41612 CONNECTOR TYPES CONNECTOR TYPE DESIGNATION MALE / PINS RECEPTACLE PIN CONFIGURATION B Right angled Straight 2 x 32 C Right angled Straight 3 x 32 R Straight Right angled 3 x 32 DIN 41612 connector classes / levels The DIN41612 connector is classified according to the standard of the connector. There are two different IEC standards that can be used, namely IEC 60-603 and IEC 61 076-4 113. Each provides slightly different test conditions, but in both cases, Class 1 or Level 1 provide the highest quality and reliability. They are obviously are more expensive, and this is mainly as a result of the thicker gold plating on the contacts. IEC 60 603-2: Class 1 / Level 1 DIN 41612: This is the most robust form of DIN 41612 connector and for this the connector undergoes 250 mating cycles, it is then exposed to 10 days of gas using sulphur dioxide and then another 250 mating cycles. After this there should be no visual abrasion of the contact material and no functional impairment, i.e. increase in contact resistance. Class 2 / Level 2 DIN 41612: This is the next level down in the connector range. The connector undergoes 200 mating cycles, it is then exposed to 4 days of gas using sulphur dioxide and then another 200 mating cycles. After this there should be no visual abrasion of the contact material and no functional impairment, i.e. increase in contact resistance. Class 3 / Level 3 DIN 41612: This is the lowest level of connector and for this the connector is able to withstand 50 mating cycles and then is given a visual inspection for which there should be no visible signs of wear., and there should be no functional degradation. IEC 61 076-4-113: Class 1 / Level 1 DIN 41612: Again, this Level or Class is the most robust form of DIN 41612 connector under this testing regime. The connector undergoes 250 mating cycles, it is then exposed to 10 days of gas using sulphur dioxide and then it undergoes another 250 mating cycles. After this there should be no visual abrasion of the contact material and no functional impairment, i.e. increase in contact resistance. Class 2 / Level 2 DIN 41612: This level of connector is not to the same specification and as a result it is lower in cost. For the testing, the connector type undergoes 125 mating cycles, it is then exposed to 4 days of gas using sulphur dioxide and then it undergoes a further 125 mating cycles. After this there should be no visual abrasion of the contact material and no functional impairment, i.e. increase in contact resistance. Normally when mention is made of the DIN 41612 classes or levels this will refer to the IEC 60 603-2 testing regime, although some manufacturers offer connectors classified under both regimes. Typically Class 1 is the highest and used for aviation and military applications, class 2 is for industrial, and class 3 is for more general use where the number of insertions is likely to be low and where reliability is not so critical.

European printed circuit board (PCB) cards can be connected in a standard chassis, which can then be installed in a 19-inch rack, using the Eurocard standard format. The cards are fitted into the chassis`s top and bottom rows of slotted card guides so they can stand on end like books on a shelf. Each card has one or more connectors at the spine that link to corresponding connectors on a backplane that covers the chassis` rear. The DIN standards for electrical connectors serve as the foundation for DIN 41 612 PCB connectors, often known as VME connectors or Eurocard connectors. Electrical connectors having two or three rows of contacts, 16 or 32 columns per row, and 0.1″ contact spacing are permitted per the standard (2.54mm). Although the use cases for DIN 41612 connections have grown over the years to encompass any application that requires a strong and dependable board-level connector, VME Bus systems continue to be the most prevalent application for these connectors. It is a strong and trustworthy connecting solution. A wide range of applications are suitable for its broad offering. Available variations include DIN Power, DIN Signal, and DIN Mixed. There are variations of the DIN Signal that are full length (up to 96 connections), half length, and one third length. both in the normal and reverse configuration. Options for selective loading, such as first mate last break connections.

DIN 41612 Connectors DIN 41612 Connectors are widely used in rack-based electrical systems. The standard performance of these connectors is a 2 A per pin current carrying capacity and 500 V working voltage. Both figures may be variable due to safety and environmental conditions. Uses The primary use of DIN 41612 connectors are PCB connectors and motherboards, the main acceptance would be their board to board reliable connections. Types Number of contacts varies Many variations of housing material, including different types of metal and plastic Both angled and straight versions Male and female Mounting Types Cable mount Panel mount Snap pin mount Through hole

What is FPC / FFC Connectors? As its name suggests, it is a connector made for the purpose of connecting FPC / FFC. Connect the Mating part to the FPC/FFC that is arranged on the terminal. This connector-Mating FPC/FFC is also called a card. The pitch started at around 2.0mm, but gradually smaller ones became mainstream, and now the 0.5mm pitch is the most used. Also, the terminals are usually arranged in a row, but there are also ones with connections arranged in a staggered manner, mainly on smaller pitches. Here are two types of connectors Atkconn offers: a ZIF connector that can lock FPC/FFC with almost no force, and a NON-ZIF connector that can be inserted with light force.
