[0002] The Chinese name of PCB board is printed circuit board, also known as printed circuit board or printed circuit board. It is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board.

[0003] In the front end of the SMT production line, the main function is to print solder paste or SMT adhesive onto the pads of the PCB to prepare for component soldering. First, the PCB is placed on a jig for positioning. After positioning is completed, the jig and PCB are placed in a printing press to print solder paste.
