The only true dual-vessel HAST Chamber. Condensation and contamination-free test environment with controlled humidity during ramp down — the ideal HAST stress test environment for semiconductors, substrates, and materials.
When accuracy and precision count, the pioneers and inventors of HAST — Hirayama — remain the world-renowned brand.
Hirayama Manufacturing Corporation has been making pressure vessels and medical sterilizers for over 100 years — all manufactured and produced in Japan, with the most widely installed worldwide user base. They are the true pioneers of Highly Accelerated Stress Test (HAST) technology.
Semiconductors are a specialty application for the PC-R9 chambers, which are also used across materials, metals, laminates, lumber, chemical, drug, and tool manufacturing industries worldwide.
Condensation is eliminated — no condensation or rain forms inside the chamber.
Air exhaust pre-pressurization provides a more accurate, uniform test environment.
Adaptable to 100+ voltage bias or test terminals for in-situ measurements.
Built-in reservoir passes water through an anti-bacterial filter automatically.
Ensures uniform sealing, eliminating leaks and condensation catch-basin needs.
Air evaluation cycle with switch-selectable humidity control protects samples from depressurization stress.
A new programmable high-precision temperature-humidity controller enables more precise HAST evaluation than conventional chambers. An interactive touch-screen input system makes it easy to operate.
Monitor and adjust chambers remotely with an external terminal device — even when many units are installed across a wide facility.
Control and monitor up to 16 sets of devices collectively from a single PC.
Built-in USB data port and a dedicated cleaning mode, plus optional Air-HAST feature.
The test chamber and steam generator are separated and independent from each other — a round-shaped chamber design that maximizes strength while enlarging usable space to the fullest.
The mutual thermal influence between the test chamber (dry bulb) and steam generator (wet bulb) is small.
The round chamber shape maximizes usable interior space relative to overall footprint.
The independent steam generator enables a wide, stable working humidity range.
An electric clamp method opens and closes the door with the press of a button. A slide tray draws the door toward the operator, making it easy to load and unload specimens without reaching into the chamber — improving operator safety.
Bias terminals are installed on the inner face of the door, so specimen connection work at a bias test can be performed outside the chamber. 20 bias terminals are standard, expandable up to 100.
Prevents dew condensation and can set humidity at any value between 65%RH and 100%RH. Supports fixed-value operation and gradient temperature rise/fall. Conforms to IEC 60068-2-66 and JIS C 60068-2-66.
Humidity is fixed at 100%RH from the rising start time — a wet saturation test where dew condensation occurs on specimens, corresponding to conventional saturated-type pressure cooker testing.
Cools slowly with humidity maintained until temperature reaches 100°C and pressure drops to 0MPa — protects specimens from pressure stress and drying.
Cools the chamber faster than slow cooling while still minimizing pressure stress and drying.
Opens the exhaust valve immediately for the shortest specimen removal time — ideal for specimens unaffected by pressure stress.
