HDI’s circuit board requires only one micro-blind hole to fail, which is almost equal to the failure rate of 20000PPM. For HDI technology, everyone is working hard to study the process, technology, and yield improvement. The topic of discussing how HDI is really successful is rare. Xing Electronics, X Tong Computer, and X Hua Electronics are all current HDI production and mass production factories in Taiwan, including other European and Hong Kong-invested HDI investors. HDI has done a lot, but now it is difficult to escape an important issue. At the time of the problem, I also paid a lot. The industry is very strange. The article says that the gross profit is very profitable, but it won’t make much money in a long time. It is easy to make HDI boards. As long as there is a laser, motherboard manufacturers can also make HDI boards. What is not easy is how to control the entire plant ’s HDI product system concept so that it does not lose a lot of money and does not have HDI trust. The problem of degree of blistering is not a big problem, because the eyes of the quality assurance system can be easily blocked, and it will not really lose money. The invisible problem, the micro open circuit of the via, directly It is really horrible to flow out to customers. Seek like-minded colleagues. Let ’s discuss the deep theme of HDI, high yield, high reliability, and low cost.
