PCT Chamber – Pressure Cooker Test Chamber for Accelerated Reliability Testing
How a PCT Chamber Works?
A PCT Chamber heats water inside a sealed vessel to generate saturated steam. As chamber pressure rises, the boiling point of water increases, enabling test temperatures above normal humidity chambers while maintaining 100% RH conditions.
This highly accelerated environment quickly reveals product weaknesses caused by heat, moisture, and pressure stress.
Testing Standards
The chamber is suitable for reliability testing according to:
- IEC 60068-2-66.

Advanced Structural Features
Circular Stainless Steel Inner Chamber
The chamber features a circular SUS304 stainless steel structure for excellent corrosion resistance, long service life, and uniform steam circulation. The round design also helps reduce condensation dripping onto samples.
Automatic Safety Door Lock
A pressure-sensitive interlock system prevents the door from opening when internal pressure is above safe limits.
- Temperature and pressure sensing protection.
- Reverse pressure protection.
- Heavy-duty safety handle.
Built-In Water Tank with Auto Refill
The integrated water tank uses automatic level control to support continuous testing with less manual operation.
- Water level monitoring.
- Low water alarm.
- Automatic water refill.
Multi-Layer Safety Protection System
Multiple safety mechanisms ensure reliable operation under high temperature and pressure conditions.
- Over-temperature protection.
- Low water shutdown.
- Over-pressure protection.
- Automatic pressure release.
- Emergency pressure relief.
- Fault alarm indication.

Frequently Asked Questions
What is the difference between PCT and HAST chamber?
PCT chambers use saturated steam at 100% RH, while HAST chambers generally use unsaturated humidity conditions for faster semiconductor testing.
Can chamber size be customized?
Yes. Chamber dimensions, voltage, trays, controller language, and data output can be customized.
How long does a PCT test take?
Depending on product type and test standards, testing may last from several hours to several days. Accelerated conditions help shorten traditional aging cycles.
