Most PCB failures don’t happen during testing. They happen months later in the field.
For PCB manufacturers, EMS companies, semiconductor packaging facilities, and electronics assembly plants, moisture is one of the most underestimated causes of latent failures.
A board may pass QC today — and fail after 6 months due to environmental instability during manufacturing or storage.
Here’s what uncontrolled humidity leads to:
⚡ Solder paste moisture → voids & weak solder joints
⚡ Popcorning ICs during reflow → cracked components & costly replacements
⚡ Flux residue + humidity → dendrite growth & electrical shorts
⚡ Coating delamination → corrosion and premature PCB failure
⚡ Moisture absorption in laminates → intermittent reliability issues in the field
In electronics manufacturing, reliability is engineered long before final testing.
Recommended environmental control:
✔ RH: **30–50%**
✔ IPC-A-610 compliant production conditions
✔ Stable dry-air control during SMT, assembly, coating & storage
For high-reliability electronics, atmospheric precision protects:
✅ Solder integrity
✅ Component lifespan
✅ Field reliability
✅ Warranty reduction
✅ Production yield
At Rehoboth Enviro Systems Pvt. Ltd., we design industrial dehumidification systems for PCB manufacturing, SMT lines, semiconductor assembly, electronics storage, and cleanroom environments.
Because reliability isn’t tested. It’s manufactured.
