The first piece crimp contact inspection uses a three-coordinate measuring machine to detect the size of the joint surface, with a sampling rate of 100%; after mass production crimp contact pin, it is changed to sampling 1 piece for every 20 pieces. contact socket crimp Key indicators include joint surface gap (≤0.03mm) and tensile strength (≥90% of the material standard). Common crimp contact female defects and countermeasures: bubbles on the joint surface need to check whether the moisture content of the material exceeds the standard; crimp contact male metal matrix deformation requires reducing pressure or increasing crimp socket contact support structure; filler overflows to adjust the mold gap or reduce the amount of material. Unqualified female crimp contact are classified as scrapped or reworked, and male crimp contact reworked workpieces need to peel off the filler and reprocess the matrix surface.
