The right board-to-board connector for your application
The most important distinguishing features of SMT PCB connectors are the data rates and the pitch. The smaller the pitch and the higher the required connection speed, the greater and more complex the design effort required for the board. In general, a board-to-board connector or wire-to-board connector represents an interference point within the transmission path. Here, you should pay particular attention to impedance, insertion loss, and crosstalk. The higher the quality of a Leiterplatten-connector, the lower the data transmission interference.

ROBUST
Our robust and long-proven One27-connector achieves data rates of 3 Gbit/s. With a pitch of 1.27 mm, it is available with a number of positions ranging from 12 to 80. Board-to-board distances ranging from 8 to 13.8 mm can be achieved. By using the One27, boards can be connected in parallel, at right angles (right-angle), horizontally, and in wire-to-board configurations.

HIGH SPEED, PARALLEL
Our ept Colibri PCB Leiterplatten-connector offers data rates of either 10 Gbit/s or 16 Gbit/s. [SG1] The variants of the board-to-board connector with a 0.5 mm pitch have a number of positions ranging from 40 to 220. Board spacings from 5 mm to 8 mm are possible. The Colibri offers excellent data transmission characteristics, and boards can be stacked in parallel [SG2]. The ept Colibri PCB-to-PCB connector was developed for COM Express applications with 220 and 440 contacts. However, the range of applications for this board-to-board connector has since multiplied.

Connecting Printed Circuit Boards - Tips for Your Design
Even relatively early in the development phase, developers need to consider the appropriate direct PCB connection. We have compiled a list of the most important questions you should clarify in advance:
- Is a single-board solution sufficient?
- How many signals are required by the board-to-board connector?
- How much space may the board-to-board connector occupy on the PCB?
- What data data rate must the PCB-to-PCB connector achieve?
- What are the requirements for impedance, insertion loss, and crosstalk?
- What is the maximum assembly size?
- How should the boards be connected to each other?
- Is a parallel-stacked PCB connector required?
- Must the board-to-board connector be mounted right-angle?
- Or is the only option to establish the PCB connection via a wire-to-board connection?
- Which components dictate the minimum spacing between the boards?
- What are the expectations regarding electromagnetic compatibility?
- How important are shock and vibration resistance, particularly for mobile devices?
- How important is heat dissipation? Can a different component layout, using the appropriate board-to-board connector, improve heat dissipation and thermal management?
- What are the environmental conditions under which the end device operates?
- Do EMI/RFI considerations and concerns require a separation between functions and RF shielding of part of the circuit?
- Is it likely that an external I/O will need to be replaced on-site?
From single-board computers to industrial PCs: No problem
with the right board-to-board connector
As industrialization and automation advance, the demands placed on systems are constantly increasing. Popular single-board solutions often reach their limits and must be expanded. Board-to-board connector offer a simple and reliable solution.
A board-to-board connector provides maximum flexibility when connecting and disconnecting printed circuit boards. Its primary function is to transmit signals and currents. Typically, a pair of board-to-board connector consists of a Male and a Female. The high quality of our ept connectors stems, among other things, from the ideal alignment of the two connector halves with one another. Our in-depth expertise in contact geometry, contact material, and contact plating, as well as the geometry and material of the insulator for optimal air clearance and creepage distance, makes ept connectors your reliable partner. Automated processing capability, thanks to excellent coplanarity, is a given.
As mentioned earlier, circuit boards can be easily connected to one another with maximum reliability through the use of mated connector pairs. This opens up the possibility of expanding the motherboard with daughtercards. Through clever design, any number of circuit boards can be connected to one another. The limiting factor is the outer housing. Printed circuit boards can be stacked in parallel or connected at a 90° angle. wire-to-board solutions are also possible. As packing density and data rates continue to rise, mezzanine cards offer an ideal way to expand existing applications cost-effectively and flexibly. By using board-to-board connector, modules can be easily replaced. The cost-effectiveness of the computers is enhanced by maximum design flexibility. For example, a carrier board can be equipped with daughtercards performing various functions.
