Application Cases

Developing and Etching Solution for PCB Wet Processing Lines

Industry Background

Developing and etching are critical stages in PCB manufacturing, directly determining circuit accuracy and yield. These processes require precise chemical control, uniform spraying, and high equipment reliability.

Common Developing and Etching Problems

Problem 1: Uneven etching
Non-uniform spray distribution causes over-etching or under-etching.

Problem 2: Nozzle clogging
Chemical crystallization and impurities block nozzles, reducing process stability.

Problem 3: Severe corrosion
Strong acidic and alkaline environments accelerate component degradation.

Engineering Causes

Insufficient corrosion resistance of spray materials
Unstable chemical flow and pressure control
Long-term chemical fatigue of components
