Circuit board manufacturers teach you how to distinguish between board power and picture power

In the PCB circuit board industry, the electroplating method is ready-to-use, and the entire circuit board surface and the hole wall are plated with a layer of copper. The purpose is to increase the thickness of the board surface and the copper layer of the hole wall of the circuit board manufacturer to meet customer requirements .

Figure electricity transfers the PCB circuit board from the outer layer to electroplating, which is followed by secondary copper plating, the purpose of which is to increase the thickness of the outer circuit.

The copper surface attached to the outer dry film cannot be plated with copper or tin; the exposed copper surface.

(The non-photosensitive dry film area where the outer layer of the developing line is dissolved by the developer) can be plated with secondary copper or tin.

The purpose of tinning is to protect the copper surface under the tin surface from being bitten off by the etching solution in the next process.

There are two different processes in the production of circuit boards, positive film and negative film. The negative film board is charged after the copper is deposited. The main function of the board power is to increase the thickness of the copper on the inner wall of the hole and increase the thickness of the circuit copper on the board to achieve The customer’s requirements mainly include the micro-etching section, the pickling section, the copper-plating section and the various washing sections; the positive film is the outer layer of the image development, and the role of the image The copper surface exposed after development is plated with a layer of tin to protect the required circuits from being etched in the subsequent alkaline etching.

There is no difference between a circuit board and a circuit board, and they are essentially the same.

The circuit board is just a designed and manufactured substrate, and the circuit board refers to the PCB circuit board on which various components have been installed.

The names of the circuit boards are: circuit boards, PCB boards, aluminum substrates, high frequency boards, thick copper boards, impedance boards, multilayer circuit boards, multilayer circuit boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper Etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances.

Circuit board: On an insulating substrate, a printed board that connects wires from point to point is formed according to a predetermined design, but does not have printed components.

Circuit board: On an insulating base material, a printed board that connects wires from point to point and prints components according to a predetermined design.

A circuit board is the kind with electronic components. The circuit board is the kind of PCB board. There are no electronic components.

The most contacted is the circuit board, and the main board is the circuit board.
