Screening and Testing for MIC module and Amplifier Products

In order to assure the highest level of reliability, Transcom has implemented its own screening program referred from MIL-STD-883. Customized screening procedures are available on special request.

 

Testing Transcom's MIC module substrate receives 100% visual inspection and electrical testing. Wire bond testing is also conducted on assembly station in accordance with MIL-STD-883. Screening Transcom has its own screening capability to do pre-cap inspection, high temperature bake, burn in, temperature cycle (shock), gross leak, shock and vibration tests, and final mechanical and electrical inspection to assure the best quality and reliability.

 

Transcom has implemented its own screening program derived from MIL-STD-883. (See Table 1.) This standard screening applies to our Amplifier products. Customized screening procedures are available upon request.

Quality And Reliability

Figure 1 demonstrates the high temperature DC life test results of Transcom standard 1W(T5) GaAs FET. The
devices exhibit an extrapolated DC lifetime of more than 108 hours at 110 C Channel Temperature. The MTTF test
results derived from three elevated channel temperatures of 226 C, 246 C and 260 C. Failure of the devices
defined as 20 % degradation in Idss from room temperature values.
