The technology level and quality of PCB and PCBA products are also facing serious challenges, along with the high density of electronic products and lead-free of electronic manufacturing. PCB design¡¢production and processing and assembly process needmore strict process and control raw materials. Due to the technique and technology is still in the transition period at present, customer knowledge of PCB manufacturing and assembly exist bigger difference. Sofailures similar to theelectric leakage, open circuit (circuit, hole), rack of fusion and blasting plate layersare of common occurrence.It often causes the quality responsibility of the dispute between suppliers and users,which led to the serious economic loss.Failure analysis of PCB and PCBA failurephenomenon, verification through a series of analysis, identification the reasons for failure and mining failure mechanism make important significance to improve product quality, improve production technology and arbitrate failure accidents.
