PCB Cleaning Troubleshooting Guide

Poor cleaning manifests as visible residue, ionic contamination, or functional failures. Systematic troubleshooting isolates root causes.

Common issues and solutions

Typical problems include insufficient chemistry strength, inadequate agitation, nozzle clogging, rinse contamination, or degraded DI water. Address each systematically with controlled tests.

Troubleshooting checklist

• verify chemistry concentration and temperature

• inspect nozzles and basket loading for shadowing

• check rinse water quality and flow patterns

• run worst-case test vehicles to reproduce the issue

• consult analytical data (IC, TOC) to pinpoint contaminants
