1. Q: Doe Liujing produce power semiconductor or only trading? A:Liujing has own factory, can control the production and quality directly.
2. Q: How does Lujing control the product quality? A: 100% of the products will be tested . Firstly we will test chip parameters . After the chip encapsulation . we test 100% of the thyristors again. Each chip and thyristor should pass all these QC procedures before shipping to customer.And we will deliver goods with all testing parameters wrriten in the paper.
3. Q: Could Liujing provide technology support? A: Liujing is specialized in manufacturing power semiconductor. If there's any problem,we'll provide suggestion from our engineer to help you to solve problem.
4. Q: Which field can Liujing power semiconductor be used on?
A: Liujing power semiconductor can be used on Locomotives, industrial transmission, motor soft start, high voltage dc transmission, high voltage reactive power compensation, the motor excitation, induction heating...
