The plastic encapsulated DC/DC converters have been widely used in data communication, oa equipment, industrial instruments etc. in these years. One of the fundamental problem which obstacle to its further application is the unreliability of the pins. In light of a batch of plastic encapsulated DC/DC converters with unweldable pins, four group contrast experiments are designed to analyze the failure...
Bipolar junction transistors can be used as switch transistors in satellite power system. In order to confirm that weather water vapor control and passive layer process effecting on transistor performance and Aluminum corrosion, 88 silicon NPN switching transistors with different process used in this paper. Experiments with temperature cycling and power on, the contrastive groups of which were with...
