Since the printed circuit board is not a general terminal product, the definition of the name is slightly confusing. They are not the same, so when evaluating the industry, the two are related but cannot be said to be the same. Another example: because there are integrated circuit components loaded on the circuit board, the news media call it an IC board, but in essence it is not the same as a printed circuit board. , the printed circuit board we usually refer to refers to a bare board-that is, a circuit board without components.

Printed circuit boards need to use dust removal devices to clean the dust on the surface of the circuit board during production. At present, most of the traditional dust removal devices use bristles to move on the surface of the circuit board to remove dust from the circuit board.
