FPC circuit board equipment knowledge

Printed circuit boards (PCBS) are found in almost every kind of electronic device. If there are electronic parts in a device, they are all embedded in PC B of various sizes. In addition to fixing various small parts, the main function of PCB is to provide the electrical connection between the above parts. As electronic equipment becomes more and more complex, requiring more and more parts, PCB lines and parts become more and more dense. A standard PCB looks something like this. A bare board (without parts) is also often referred to as a "PrintedWiringBoard" (PWB).

To secure parts to the PCB, we solder their pins directly to the wiring. On the most basic PCB, the parts are on one side and the wires are on the other. So we need to make holes in the board so that the pins can go through the board to the other side, so the pins of the parts are welded to the other side. Because of this, the front and back sides of a PCB are called Component Side and Solder Side respectively.

If there are some parts on the PCB that need to be removed or put back after manufacture, then zero

The Socket will be used during installation. Because the socket is directly welded to the board, the parts can be arbitrarily disassembled. A ZIF (Zero Insertion Force) plug allows parts to be inserted and removed easily. The lever next to the socket can hold the parts in place after you insert them.

To connect two PCBS to each other, an edge connector is commonly used. The gold finger contains a number of bare copper pads that are actually part of the PCB wiring. Normally to connect, we insert the gold finger on one PCB into the appropriate Slot (commonly called expansion Slot) on the other PCB. In computers, display cards, sound cards, and similar interface cards are connected to the motherboard by means of a gold finger.
