This part is made from very thin tin-plated steel, only 0.3mm, so it is prone to warping, scratches and burrs during stamping.
The two V-shaped legs must be squeezed to the correct opening, equal in height and in a straight line, since they mate directly with another part and even a small deviation causes a poor fit.
The part goes through two stamping steps run at the same time on two dies, so dimensions must be kept consistent between the steps.
In addition, the thin tin layer on the surface must not peel or get scratched, as this affects electrical contact and solderability.
