Electroplating Grade

Problem Solved

Common thiourea has high moisture content causing plating solution decomposition, resulting in black coatings with multiple pores.

Our Solution

Moisture content ≤0.1% increases electrolyte stability by 30%.

Case Study Results

PCB factory yield increased from 85% to 96% (with comparison chart).
