Identify the advantages and disadvantages of a PCB board, see these points?

The circuitry on the circuit board is designed to bend to ensure the stability of the signal. Circuit board design is a kind of technical work, only using the corresponding design to ensure the stability of the signal.

Advantages and disadvantages of different PCB surface treatments

There are many kinds of surface treatment of the circuit board. PCB proofing personnel should choose according to the performance and requirements of the board.

The surface treatment technology of PCB board and its advantages and disadvantages and application scenarios

The circuit board inside the line is mainly pure copper, that is, bare copper plate. Some people think that the gold color is copper, which is the protective layer on the copper.

The advantages and disadvantages of common PCB surface treatment technology

The OSP acts as a barrier between the copper and the air. Simply put, it chemically grows an organic film on a clean, bare copper surface. The only function of this organic film is to ensure that the inner copper foil does not oxidize before welding.
