What is PCB migration poblem ?
■.What is PCB migration problem ? - Migration is narrow space short problem in high temperature and humid. It is abbreviated as ECM (Electrochemical migration) ■.Why occur migration ? - In Electrolyte, apply power to both metal. Electrical potential is difference and move electron move from the positive electrode to the negative electrode, and the ions of the electrode carry the metal ions along..
