  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,

• Board-to-board (BTB) connectors Types 2023-07-11

  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)

• VME connectors/Eurocard connectors introduction 2023-07-09

  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.

• What is FPC / FFC Connectors? 2023-07-07

  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.

• what is Eurocard Connectors/ DIN 41612 / IEC 60603-2 Connector? 2023-07-06

  Eurocard Connectors per DIN 41612 and IEC 60603-2 DIN 41612 was a DIN standard for electrical connectors that are widely used in rack based electrical systems. The most widely known use of DIN 41612 connectors is in the VMEbus and NuBus systems. The standard has withdrawn in favor of international standards IEC 60603-2 and EN 60603-2. DIN 41612 connectors are used in Pancon, STEbus,Futurebus, VMEbus, Multibus II, NuBus, VXI Bus,eurocard TRAM motherboards, and Europe Card Bus, all of which typically use male DIN 41612 connectors on Eurocards plugged into female DIN 41612 on the backplane in a 19-inch rack chassis. Mechanical The standard describes connectors which may have one, two or three rows of contacts, which are labelled as rows a, b and c. Two row connectors may use rows a+b or rows a+c. The connectors may have 16 or 32 columns, which means that the possible permutations allow 16, 32, 48, 64 or 96 contacts. The rows and columns are on a 0.1 inch (2.54 mm) grid pitch. Insertion and removal force are controlled, and three durability grades are available. Often the female DIN 41612 connectors have press fit contacts rather than solder pin contacts, to avoid thermal shock to the backplane.

• Types of FPC / FFC Connectors 2023-07-05

  Types of FPC / FFC Connectors ZIF and NON-ZIF connectors ZIF connector ZIF is an abbreviation for Zero Insertion Force, and refers to a connector that has zero insertion force, that is, no force is applied when mating the FPC/FFC to the Mating. On the other hand, the terminals must have contact pressure at the Mating part of the connector and the card, and it is also necessary to hold the card. The ZIF connector has a locking mechanism for that purpose. There are mainly three types of locking mechanisms, called slider cover type, front flip type, and back flip type. slider cover type After inserting the card into the connector, a part called a slider cover pushes down the card together with the terminals, and has a locking mechanism that maintains contact pressure and card retention. It has been used from the beginning among the three types of locking methods. While it has high card holding power, it is disadvantageous in terms of size and workability. Front flip type Compared to the slider cover type, this type has improved workability and size disadvantages. By occupying the cover that falls to the card side, it has a mechanism to hold down the card. As mentioned above, it has superiority in terms of size and workability, and is now being used more than the slider cover type. On the other hand, there are issues with the holding power when the card is tilted upwards, and if a strong holding power is required, it may be avoided. Back flip type It is a type that knocks down the lever behind when viewed from the card insertion side. Compared to the front flip type, it is more resistant to card tilt and tends to have better holding power. On the other hand, there are cases where the connector size tends to increase in

• How to mount the connector on the board? 2023-07-04

  How to mount the connector on the board? Flow and Reflow: Part Soldering Process Methods for automating the soldering of parts that started by hand can be broadly divided into "flow implementation" and "reflow implementation". Flow mounting is a method in which a board containing a component is passed over a tank containing melted soldering, and solder is soldered by squirting out solder from the bottom. On the other hand, the reflow implementation is a soldering powder (cream soldering that has been pasted at the same time as the part in advance. ) in the necessary place on the substrate, pass it through a "furnace" under high temperature as if baking it in an oven, melt the solder and implement it. In recent years, surface-mount components called SMT (Surface mount technology) or SMD (Surface mount Device) have become more common in order to effectively utilize both sides of the board and to improve mounting density and productivity, and reflow is naturally becoming mainstream. Types of each type of mounting on the board of the connector dip type This type is plating (VIA) with plating that makes a hole in the board and connects it to the trace, inserts the "lead" of the connector into it, and solders it. As a feature, the mechanical strength of the board mounting can be kept high, but there are also aspects where it is difficult to reduce the size and mount it at high density. In principle, connectors are soldered by hand or flow process, and the disadvantage is that it can not cope with the mainstream reflow process in recent years. However, there are also connectors with special specifications called "pinyin paste" that allow implementation in the reflow process while taking advantage of the advantages of this type (also called "through-hole reflow", "reflow dip", etc.). In this type, cream soldering once extruded out of the through-hole is soldered by suck

• What is a electrical connector? 2023-07-03

  What is a connector A connector is a component that forms an electronic/electrical circuit through electrical connections. The word "connector" means "something to connect", and it is used for various things today. Connectors that connect water pipes and air cylinders, connectors that connect web data, and recently jobs and titles that connect people and jobs are also called connectors. Atkconn manufacture and sell electrical connectors, which are the most popular types of connectors. We will introduce how the connector, which connects electricity between "something" and "something", has changed and evolved since its origin, and IRISO 's efforts. Diversification of connectors Visible external connector Connectors are classified into those used outside to connect devices and units, and those used to connect inside devices and units, mainly between boards and parts. Connectors were born in the form of connecting electric wires, but the form of connecting outside the equipment is still the mainstream today. With the advancement of advanced functions, there are many things that everyone has a chance to see, such as things that connect to outlets, USB and network connectors. Internal connector used in equipment On the other hand, the spread of printed circuit boards has become an epoch-making (epoch-making invention) for devices used inside equipment, and several other forms of alternatives have been invented and spread. I'm coming. For example, connectors called "board-to Board to Board Connector" and "board-to-board" that connect one board to another board, and flexible printed circuit (FPC), which was invented as a flexible printed circuit board. In addition, a connector was born that connects an alternative to FPC via FFC (flexible flat cable) made by a more electric wire manufacturing method.

• What is a WtoB wire-to-board connector? 2023-07-02

  What is a WtoB connector? WtoB is an abbreviation for wire-to-board, and is a connector for connecting wires and PCBs. As I touched on in "What is a connector?", the world's first connector is said to be the one that made it possible to remove the soldered connection of electric wires. It is a product from There are two types of paired connectors: a board-side connector that is mounted on the board and a wire-side connector that attaches the electric wire (there are also connectors that mount the electric wire directly to the board, and these are also included in this category). The size varies depending on the compatible wire. Wires range from thin as a thread to as thick as a club, and there are connectors to suit each type. Except for special ultra-fine wires, wires used for internal wiring of equipment are mostly #30 to #18 in terms of AWG (American wire gauge), and the pitch between connectors is 1.0 to 1.0. About 5.0mm corresponds. There are various methods of attaching wires to connectors, but the most common methods are crimping and pressure welding. crimping and pressure welding What is crimping In this method, a crimping term

• What is a Board to Board Connectors? 2023-07-01

  What is a Board to Board Connectors? As its name suggests, it is a connector that connects boards to boards. It is also called Board to Board Connector, board-to-board connector, etc. It started with a pin (called a pin header) that stands on the board and a socket into which it is inserted. Since then, Board to Board Connectors of various shapes have appeared in response to various applications and size requirements. Compared to cases where connections are made via wires or FPC / FFC, the connections are neat and compact. Connection form When Mating connectors, in principle there are male and female = plug and Socket, and depending on the mounting and Mating on the board, there is a straight type (hereinafter referred to as ST type) and a right angle type (hereinafter referred to as RA type) ) exists. Board to Board Connectors have three types of connections depending on the combination of these. Stacking connection ST type + ST type Boards can be connected in parallel by using ST type for both Socket. If one of the boards becomes a child board, it is called a mezzanine connection, etc., as if it were a two-story structure. Connectors for Stacking connection are therefore also called mezzanine connectors. Adjust Mating Height by selecting the height of each plug and

• What are connector pitches? 2023-06-29

  What are connector pitches? Connector Pitch is the measurement from the center of one contact to the center of the next contact. When a connector has multiple rows, the pitch in each row and the pitch between rows may be different. There are numerous factors for the hardware designer to consider when choosing the correct connector pitch: Space Constraints - The smaller the pitch, the smaller the connector can be. In addition, smaller pitch can offer a greater number of contacts within the same space. Electrical Parameter – Pitch size has a positive correlation to electrical specifications such as current rating and dielectric withstanding. Other Physical Constraints - Depending on the design, Greenconn offers numerous low-profile connector options across all pitches. We also accept customization requests. Greenconn`s board-to-board connectors are available in the following rows: Rows: ATKCONN offers headers and recepticles in single, double, triple, and quadruple row configurations. Single and dual rows are popular choices, while triple and quadruple rows are offered in a smaller number of pitch and style options.

• What are the Connector Contact Materials and Plating? 2023-06-28

  What are the Connector Contact Materials and Plating? Base Material Our connectors typically use a copper alloy as the base material for their contacts (pins). However, different alloy materials offer various levels of conductivity performance and physical endurance. Here`s a comparison of the common base materials : Brass Lowest cost Good strength and spring properties Good conductor Phosphor Bronze High level of strength and conductivity Superior elasticity Excellent fatigue resistance Berylium Copper (Be-Cu) High level of strength and conductivity Highly expansive Plating Plating affects the connector`s performance, life cycle, quality, and cost. Plating involves two parts: underplating and finish plating: Under-plating Underplating is used to enhance the performance. This process forms an internal diffusion barrier (Zn and Cu through gold) and prevents pollutants from reacting with base metals. It also acts as a medium to help the finish plating adhere to the base material. Nickel is the most common and important under-plate in current use for these reasons: Corrosion resistance Wear resistance Solderability Finish plating Finish plating is the second step of the plating process that helps strengthen the electrical conductivity. There are various options for finish plating, depending on the design requirements and budget. I. Gold Plating: Excellent resistance to corrosion Excellent conductivity and low electrical resistance High cost II. Tin Plating: Excellent solderability and conductivity Low durability and can form an oxide film High cost *Ti

  What is Box headers or shrouded headers? Box headers or shrouded headers are pin headers that feature a plastic guide box or shroud surrounding the pins. This plastic box helps to prevent damage to the pins when it has yet to be mated and provides for an easier mating process of the connectors. Box headers are offered with keying and polarized features that prevent mis-mating. They are available with a square notch cut out of the plastic box to make sure the compatible connector is mated in the correct way. Box headers can be used in an array of applications and, because of their competitive prices, are a great solution for your board-to-board connector solution needs.

• What is Pin Headers and Female Header? 2023-06-25

  Headers are a simple connector that can be used in a wide variety of applications, from industrial to consumer electronics. Pin headers consist of one or multiple rows of metal pins aligned into a molded plastic base. Pin headers come in a vast selection of options related to the number of pins or rows, pitch, height, and mounting orientation. Pin headers offer inexpensive, reliable, robust solutions to effectively connect one PCB to another. Pin headers are known as the male side of this connector solution. Their corresponding counterpart is known as the female header. Female headers are the corresponding parts of headers that mate directly to male pin headers. Female headers (often referred to as socket headers) are made of a plastic housing with many sockets where the male pins are meant to fit. Just like pin headers, female headers are offered in one to four row configurations with a varying number of pins per row. They, paired with pin headers, can also be applied to applications in various industries that require PCBs to be connected. Headers, therefore, provide effective, cost-saving solutions for board-to-board interconnects.

• Why use BTB connectors? 2023-06-23

  Why use BTB connectors? There are at least ten design, production, and marketing situations where using two or more interconnected pc boards rather than a single one makes sense: Where form factor constraints limit the overall size of a single, larger board approach, and a three-dimensional arrangement is needed to take advantage of available package depth. Where it is unacceptable to place low-level, highly sensitive analog I/O or RF circuits near high-speed, noisy digital circuits. Where high voltages are present, and good engineering practice as well as regulatory standards mandate separation. Where thermal concerns require placing hotter components in a separate location for improved dissipation and thermal management. Where a given circuit subsection may be used or reused across multiple versions of a product, such as a core processing board which is paired with basic multiline user display and pushbuttons, as well as with a more sophisticated graphic touchscreen for different models of an alarm or sensor system. Where production requires special components, such as power devices and heatsinks that call for a special manufacturing/assembly process or manual insertion, while the rest can use automated insertion and soldering. Where the vendor expects to upgrade one function in a system, such as the processor and memory, but wants to leave the analog function unchanged for technical confidence and cost amortization. Where field experience indicates that one part of the system, such as outward-facing I/O, is more likely to need field replacement, while internal core functions such as processor and memory will have a longer mean time to failure (MTTF). Where some components need thicker PC board material and heavier copper cladding, such as for power components. Where EMI/RFI considerations and concerns mandate separation between functions, and perhaps even RF shie
