PCB Solder mask developing machine

Features:The PCB Solder mask developing machine is designed for PCB solder mask resist development, featuring auto spray imaging and a high-precision oscillation system.

Working Principle

The PCB solder mask developing machine works by spray developing solution to remove unexposed solder mask resist from a circuit board. After UV exposure, the machine uses chemical developers to dissolve the unwanted resist, revealing the circuit pattern. Adjustable settings control temperature, spray pressure, speed and time for precise development and accuracy.
