The key distinguishing features of SMT PCB connectors are data transfer rates and 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 PCB connector, the lower the data transmission interference.

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:

As industrialization and automation advance, the demands placed on systems are constantly increasing. Popular single-board solutions often reach their limits and need to be expanded. Board-to-board connectors offer a simple and reliable solution.
A board-to-board connection provides maximum flexibility when connecting and disconnecting printed circuit boards. Their primary function is to transmit signals and currents. Typically, a pair of board-to-board connectors consists of a male connector and a female connector. The high quality of our ept connectors stems, among other things, from the ideal alignment of the two connector halves with each other. Our in-depth expertise in contact geometry, contact materials, and contact coatings, as well as the geometry and material of the insulator for optimal air gaps and creepage distances, makes ept connectors your reliable partner. Automated processability due 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 connector pairs. This opens up the possibility of expanding the motherboard with daughter cards. Through clever design, any number of circuit boards can be connected together. The limiting factor is the outer housing. 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 transfer rates continue to rise, mezzanine cards offer an ideal way to expand existing applications cost-effectively and flexibly. By using board-to-board connectors, modules can be easily swapped out. The cost-effectiveness of the computer is enhanced by maximum design flexibility. This allows a baseboard to be equipped with daughter cards performing various functions.
