ESS traditionally increases product reliability four times that of unscreened electronics.

What is ESS?

Environmental Stress Screening (ESS) is a means of screening electronic assemblies at the most cost-effective point of manufacture to expose defects that can't be detected by visual inspection or electrical testing. These defects are typically related to defective parts or workmanship and are normally found as early field failures.

1. Explore Temperature Chambers by KOMEG Different Series:

    KMT-R Series, KMT-L Series, KMT-S Series

Simulate high and low temperature environments in Associated Environmental Systems bench top or floor model temperature chambers.

1) Working volume from 64 to 1000 cubic L.

2) Conform to commercial and military standards for high and  low temperature tests.

3) Self-contained single-stage refrigeration systems support low temperatures to -158°F / -70°C.

4) Two-stage cascade refrigeration systems support low temperatures to -140°F/-60°C. The two separate closed refrigerant circuits each use a different refrigerant with its own compressor.

2. High temperature limits of test chambers

There are many types of test chambers, but they all high and low temperature limits. Let's take a look at the typical high temperatures thresholds and why they exist.

Test chambers usually have wire heaters made of a material called Nichrome. By placing successive loops of heater wire, a greater amount of heat that is generated. The result looks a lot like the inside of a toaster. Fans circulate the air past the heaters, so the samples in the chamber are not exposed to radiant heat. It is very easy to add heaters and increase the speed and / or high limit of a chamber.

KOMEG chambers typically have a high temperature limits under 200°C. Here is a break-down of why a chamber's high temperature limit exists:

150°C: There are two reasons we may limit a chamber to 150°C. First, there may be a limitation of the materials used inside the chamber. Secondly, for extremely fast chambers, we may limit the high temperature to avoid problems with accidentally tripping overheat protection devices.

170-180°C: Most models stop at this temperature range. There is a risk of burning the oil inside the refrigeration's cooling coil.
