What is board-to-board connector and what does it do

Keywords: board-to-board connector, connector, connector type, electronic product connector design

A board-to-board connector is a miniature coupling plug and socket that connects power and signals directly between printed circuit boards through the pins of the connector. Copper alloy materials are commonly used to prevent board-to-board connectors from oxidizing and resulting in reduced conductivity.

In the electronics manufacturing industry, if in the circuit board design stage, the entire device may need suitable space, PCB if tends to take up too much space, the device can be divided into two or more boards. Board-to-board connectors can connect power and signals to complete all connections.

The use of board-to-board connectors simplifies the board design process. These devices may not be able to accommodate larger device PCBS. Whether it's squeezing a device or product into a single PCB or multiple PCBS, all of this takes into account power consumption, unexpected signal coupling, the availability of widgets, and the total cost of the finished device or product.

In addition, the use of board-to-board connectors also simplifies the production of electronic devices. In electronics manufacturing, simplification reflects significant cost savings. Each unit area of the PCB has more traces and components. Depending on the investment in the complexity of the manufacturing plant, the device or product is best designed as several interlinked MDIs rather than a single high-density board.

The through-hole technology of board-to-board connectors allows a third dimension to connect PCB marks and components. The first PCB can be used in both horizontal and vertical directions along the PCB conductive copper trace line. Then add more layers of the board on both sides, and there are almost several single-layer PCBS on both sides of the PCB. A typical five-layer or multi-layer PCB can be less than 0.08 inches (2mm) thick. Through holes have a conductive surface carrying current between any two layers of a multi-layer PCB.

Thanks to mature technology, modern electronic devices are more reliable and cheaper to manufacture. Multilayer PCB manufacturing used to be a huge challenge due to the hidden connections between two or more layers of copper wire. Surface mount technology (SMT) facilitates production because PCB-mounting components are easy even without drilling. In surface mount technology, component PCBS are adhered to by robotic devices. The leads of the component and the leads on the PCB pad are pre-tinned before the adhesive is applied to the lower side of the component, and the entire welding process is completed when the PCB is reflow or remelted and cooled.
