What are the common quality problems of diodes and what causes them
Common quality problems of diodes mainly include: electrical breakdown of the product, easy breaking of the cover strip, and poor appearance; There are six reasons for the problem.
1、 Selection error, insufficient material selection margin;
2、 The diode packaging stress is not completely released;
3、 The chip quality is poor, and the ability to withstand current is lower than the rated standard;
4、 Large reverse leakage;
5、 Using circuits subject to high current or voltage surges;
6、 The operator's carelessness resulted in poor appearance.
