Does Wuxi Ding Jian Technology need to wear dust-free clothes?

This depends on other stations. Inner layer, lamination, drilling (in some factories), outer layer, negative film and solder mask are not needed in some stations of these courses. In fact, the level of clean rooms in Ding Jian is not very high. Look at your question, you don't just want to ask this little question. I've been inside for a long time, and I know all the stops. You can ask me again if you have any questions. I hope I can help you.
