Designed for consistent, repeatable results

HAST (Highly Accelerated Stress Test) chambers reduce the time it takes to complete humidity testing for semiconductors. By elevating temperatures above 100°C and increasing the pressure, simulation of normal humidity tests can be made while maintaining the same failure mechanisms. Tests can be completed in days, not weeks. Our HAST systems have a modern design that’s easier to use.

  • Automatic humidity filling
  • Automatic door lock
  • A more square workspace, allowing more product to be loaded
  • Convenient, hermetic power-pin system for bias testingr

We now offer a hermetic port connection to allow special signal lines like coax or fiberoptics to be run into the chamber.

Operation Features

  • Unsaturated or saturated humidity control
  • Multi-mode M System (wet bulb/dry bulb) controls humidity, even during heat-up and cool-down. Fully conforms to EIA/JEDEC Test Method A110 & 102C.
  • Programmable controller with temperature, humidity, and count-down display. Stores up to 10 test profiles, with 30 steps per profile.
  • 12 Specimen power terminals, allows power-up of specimens (12 per workspace on “double” units)
  • Two feed-through ports, each 0.75″ NPT 
  • Automatic fill of the humidity water at the start of a test (except TPC)

Cabinet Features

  • Inner cylinder and door shield protect specimens from dew condensation
  • Interior is shaped more like a square for easier product loading (TPC model is cylindrical)
  • Two stainless steel shelves
  • Set of casters for easy movement of the chamber (except double-stacked models)
  • Push button door lock (except TPC)
  • Bottom of the unit allows storage space for peripheral equipment

Safety Features

  • Overheat & over-pressure protectors
  • Door lock safety mechanism to prevent opening of the door while the chamber is pressurized
  • Specimen power control terminal: shuts down the product power in the event of an alarm
