Focusing on precision stamping processing, dongguan precision professional custom precision shrapnel, precision terminal, all kinds of precision stamping parts.
Mainly for intelligent digital, new energy vehicles and other high and new technology enterprise difficult mass production of precision hardware, and the public, amphenol, jinlong machinery, and other industry giants long-term cooperation.
Precision stamping parts in internal residual liquid and additive to vomit, and the tin plating adhesion, easy to corrosion by these substances.
Cause the surface oxidation, coating yellowed.
Insufficient post-processing and artifacts not drying can also lead to coating yellowed.
Tetravalent tin an excessive amount of adhesion, additive, zinc plating bath with impurity pollution (
, coating thickness is not enough, iron impurity pollution (
Phenomenon in the process of plating is not easy to find)
And storage environment.
These are the cause of precision metal stamping parts yellow.
Precision wish you a prosperous business, all the best, if you want to learn more dynamic, can scan the qr code, pay attention to the public.
, is committed to precision stamping processing factory of the world's most professional electronic components
