Description

Technical Field

[0002] PCB board, also known as printed circuit board, is an important electronic component. It is based on an insulating board, cut into a certain size, and has at least one conductive pattern attached to it. It is used to replace the chassis of the previous electronic components and realize the interconnection between electronic components. Since this board is manufactured using electronic printing technology, it is called a printed circuit board. The core board of the PCB board has a blind buried hole structure. In the process of core board production, the first processing procedure is drilling. The drilling device is used to drill directly on the core board.
