Through the test of ESD(Electro Static Discharge) for PCB circuit, we are able to research on the ESD effect. This paper also studys on the ESD test method for measurement. In the measurement of the discharge current, we used current probe(TC-1). The applied voltage to the PCB metal is -3 kV HBM mode. In conclusion ESD influences exponentially greater impact in nearer PCB circuit.

PAM(Power Amplifier Module) is the important part of a mobile phone transmitter. It amplifies the strength of signal transmitting from a mobile phone to base stations enough to resist noise or interference. In this paper reliability assessment criteria for the PAM are established in terms of quality certification test and lifetime test. The former quality certification test comprises general performance test and environmental test. Items which pass the test undergo lifetime test which guarantees the extent of mean lifetime with certain confidence.
