UP-6124 Steam Aging Test Chamber

HAST-Highly Accelerated Stress Test Chambers

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, or weeks. Our HAST systems have a modern design that’s easier to use:

1, Automatic humidity filling

2, Automatic door lock

3, A round workspace,allowing wider sample boards to be loaded

4, Convenient,hermetic power-pin system for bias testing

We now offer and “Air HAST” modification for faster testing of lead-free solder whisker resistance to humidity.

Operation Features

1,Unsaturated or sturated humidity control

2,Multi-mode M system(wet bulb/dry bulb) controls humidity,even during heat-up and cool-down.Fully conforms to EIA/JEDEC Test Method A100 & 102C

3,Touch-screen controller with temperature,humidity,and count-down display.Includes Ethernet Interface.

4,12 specimen power terminals,allows power-up of specimens(12 per workspace on "double" units)

5,Automatic fill of the humidity water at the start of a test.

Cabinet Features

1,Inner cylinder and door shield protect specimens from dew condensation

2,Interior is cylindrical for maximum product loading

3,Two stainless steel shelves

4,Set casters for easy movement of the chamber(Except double units)

5,Push button door lock

6,Bottom of the unit allows storage space for peripheral equipment.

Safety Features

1,Overheat & Over-pressure protectors

2,Door lck safety mechanism to prevent opening of the door while the chamber is pressurized

3,Specimen power control termainal:shuts down the product power in the event of an alarm.
