PCB Screen Printing Board Manufacturing Process

PCB Screen Printing Board Manufacturing Process, PCB Bandage Steps: Frame Cleaning–Horizontal Verification–Layered Gel–Wire-pulling–Tension Measuring–Glue–Offline, Edge-sealing–Storage.

HASL hot air solder leveling process for PCB

HASL is a relatively mature technology at present, but its quality is difficult to control and stabilize because its process is in a dynamic environment of high temperature and high pressure.

Etching process and process control of printed circuit board

The process of printed circuit board from optical board to displaying circuit pattern is a complex process of physical and chemical reaction.
