Printed circuit board production refers to the production of printed circuits, printed components, or conductive patterns formed by the combination of the two on an insulating substrate according to a predetermined design. On the insulating substrate, electrical connections between components are provided. The conductive pattern, called printed circuit, does not include printed components. The printed circuit or the finished board of the printed circuit is called the printed circuit board or the printed circuit board, also called the printed board. What are the basic functions of the printed circuit board? Let's take a look together.

The substrate made of the printed circuit board is generally made of insulating, heat-insulating, and not easy to bend materials. The small circuit material that can be seen on the surface is copper foil. The copper foil was originally covered on the entire board, but part of the copper foil was etched away during the manufacturing process, and the remaining copper foil became a grid-like small circuit . These lines are called wires and are used to provide circuit connections for components on the printed circuit board.

In order to fix the components on the printed circuit board, the pins can be soldered directly on the pads. Pads are used to fix component pins or lead out connections, test lines, etc. Pads have various shapes such as round and rectangle. On the most basic printed circuit board (single panel), the components are concentrated on one side, and the wires are concentrated on the other side. In this case, holes need to be made in the board so that the pins can pass through the board to the other side, so the pins of the components are soldered on the other side. Therefore, the front and back sides of the printed circuit board are called the component side and the solder side respectively.

If you want to connect two printed circuit boards to each other, you generally use golden finger edge connectors. The connector shrapnels are connected to conduct pressing contact and conductive interconnection. Generally, when connecting, insert the golden finger on one of the printed circuits into the appropriate slot on the other printed circuit (generally called the expansion slot Slot). Since gold has good electrical conductivity, it will not be directly oxidized at low and high temperatures, will not rust, and the electroplating process is also very easy, and the appearance is also good, so almost all contact surfaces in the electronics industry choose electroplated gold. In a computer, graphics display cards, sound cards, network cards, or other similar interface cards are connected to the motherboard by means of golden fingers.

The role of the printed circuit board in the electronic equipment is: to provide fixed and assembled mechanical support for transistors, integrated circuits, resistors, capacitors, inductors and other components; to realize transistors, integrated circuits, resistors, capacitors, inductors and other components The wiring and electrical connection and electrical insulation between the components meet its electrical characteristics; provide recognition characters and graphics for the inspection and maintenance of components in the electronic assembly process, and provide solder mask graphics for wave soldering.
