汽车用PCB品质可靠性分析(国外英文资料) Auto PCB quality reliability analysis One, preface:? ? The current domestic automobile low proportion of automobile electronic application, every new car automotive electronics spending, on average, 4.8% of the value of the vehicle, the global average of 26.2% over the same, some even luxury sedan in electronic devices, more than 50% of the cost of the vehicle [1], gap and development should be fairly obvious. The low proportion of domestic car electronic equipment is mainly limited by rd and reliability. ? The status quo:? ? Chinas automotive electronics market is largely occupied by Delphi, the worlds leading auto parts maker, and Japanese electric and Bosch.

High-end products with high technology content are mostly foreign brands. ? ? PCB supply for car use, many domestic enterprises have already see the unlimited business opportunities, have all the philistines, to high zhuofei, shantou ultrasound, bead, have good electronics, Stanley electronics (China)... Passed QS9000 certification, such as introduction to get a coup
