Description

Technical Field

[0002] PCB, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Solder mask plugging is a relatively important process in the PCB manufacturing process. The traditional solder mask plugging method is that a printer prints ink into the holes of the PCB through a screen. The PCB is placed on a workbench. The ink will compress the air when it is plugged into the holes of the PCB, increasing the air pressure between the hole and the workbench, resulting in an imbalance in the air pressure inside and outside the hole, thereby preventing the ink from entering the PCB hole.
