What are the common quality problems of diodes? What causes it?
Common quality problems of diodes mainly include: electrical breakdown of products, easy breakage of cover tape, and poor appearance; There are six reasons for the problem.
1、 Wrong type selection and insufficient material selection allowance;
2、 Diode packaging stress is not fully released;
3、 The chip quality is poor, and the current bearing capacity is lower than the rated standard;
4、 Large reverse leakage;
5、 The circuit is impacted by high current or high voltage;
6、 The operator's carelessness leads to poor appearance.
