Test items

-Routine test

It mainly tests the appearance, size, electrical performance and safety performance of electronic components. Test the basic parameters according to the device specifications, such as the triode, to test the appearance, size, ICBO, VCEO, VCES, HFE, pin tension, pin bending, solderability, welding heat resistance and other items, and test RoHS for some export products.

-Reliability test

It mainly tests the life and environment of electronic components. Test the device's life and various environmental tests according to the user's requirements and specifications, such as high temperature test, low temperature test, humidity test, vibration test, maximum load test, high temperature durability test, etc;

-DPA analysis

It mainly controls the internal structure and process of the device. For example, the main means of triode are X-ray monitoring of internal structure, acoustic scanning monitoring of internal structure and packaging process, and unsealing monitoring of internal wafer structure and size.
