Service Introduction
Among the faults of electronic appliances, those caused by welding abnormality accounts for as high as 80%. Therefore, the welding strength has become a major indicator in evaluating the quality of welding points. And whether there are cracks and holes in welding appliances is generally regarded as the main factor in such evaluation. During the installation and use of the appliances, if the welding temperature curve is not appropriate or the mechanical stress-resistance is weak, great holes or cracks might be made, seriously affecting the touching performance of appliances, and even triggering ill touch between them or making them separate from the connecting areas in severe cases. On the other hand, if the chips are influenced by the above-mentioned factors, cracks will be made on solder balls, which will dramatically affect the welding quality of chips and leave their electrical performance abnormal.
