The look can be welded metals were wet, when the high temperature solder is melted. And forming an alloy layer on the contact surface with the metal connectors to be welded together. General assembly of electronic products, the main use of tin-lead solder, solder wire, Shanxi, known as solder. Depending on the melting point of the solder can be divided into hard and soft solder; it can be divided according to the different composition of tin-lead solder, silver solder, copper solder. Tin copper drain means the original point with the board, the solder wire wholesale, non-wetting caused by a variety of situations. After welding is completed icicles that is, solder offer, the solder joints irregular shape appears sharp, the aid may be solder wire activity is not strong impact on solder wetting and scalability affect the poor welding. That crude tin rough surface after welding. This phenomenon described indicators contain other metal impurities in the solder caused by high production does not meet specifications.
