Usually based on workpiece material and thickness, with reference to the kinds of materials selected  copper alloy welding wire, first determine the shape and size of the electrode end. Second, the welding electrode   force and welding time selected, and then adjust the welding current, welding current of different samples, the inspection nugget diameter to meet the requirements, then adjust the appropriate range of electrode pressure, welding time and current, the sample welding and inspection, until the solder joint quality and full compliance with the requirements of technical conditions so far. The most common method is to tear the specimen test method, high-quality solder joints are marked: in the tear samples of a hole on the other chip has a round boss. Thick or hardened material sometimes can not tear out the hole and boss, but judging by the shear fracture nugget diameter. If necessary, the need for low-fold measurement, tensile stretch test and X-ray examinations to determine the penetration rate, shear strength and the availability of shrinkage, cracks and so on.

To sample selection of process parameters, we must fully consider the specimens and artifacts in the diversion of ferromagnetic material, as well as differences in terms of assembly space, and the appropriate adjustment.
