DEVICE UP-SCREENING

Up-screening is the testing a device to a wider temperature range than the original manufacturer specified.  Up-screening a device does not subject it to any environmental stresses (Temp Cycle, HAST, etc.).

The semiconductor suppliers today primarily develop new devices for the commercial consumer electronics markets where devices are typically tested from 0°C to +70°C.  However the demand for sophisticated electronics in the military, space and industrial markets is higher than ever.  Many of the applications in these markets must exist in a harsh, high-temperature environment.  The typical operating temperature range for industrial applications is -40°C to +85°C and -55°C to +125°C for military and space applications. The only way to assure commercial temperature range devices can operate at these extended temperature ranges is to perform full AC/DC/Functional testing to “Upscreen” them for these harsher environments.   

Integra has successfully upscreened millions of devices for our customers.
