American peacekeeping and Zhanhua used INPLAN a long time ago, and now they want to engage in INCAM. The medium and large PCB factories in Shanghai include: Meiwei Electronics, Hong Kong-funded Songjiang multilayer HDI board, Meiwei Technology, Hong Kong-funded Songjiang IC carrier board, COF and so on. Austrian, Minhang, China, Taiwan Province and Qingpu multi-storey HDI. Other small and medium-sized PCB factories include Pulin, which is located in Songjiang. The big one who makes soft board is Bole, and the small ones are Efu Bixi and Liangwen Changping, all in Qingpu. Jiading also has Xintai Optoelectronics, which is Taiwan-funded, making soft boards and hard boards, neither too big nor too small. Secondly, there are many small factories in Jiading, such as Shuangzhan, Xiangchengmao, Zhuokai and many others, so I won't list them one by one. 1 1. Autes can be chosen as the first choice, but I don't know whether to use inplan, followed by Meiwei. Are these two companies well treated in this industry?
