You can judge the quality of the M12 4pin waterproof connector according to the following aspects. As long as you have your own judgment, you can know that our products will definitely satisfy you.
First , the gold layer color is not normal
The color of the gold-plated layer of the pogo pin connector is inconsistent with the normal gold layer color, or the gold layer color of different parts in the same accessory product.
Secondly . Influence of raw material impurities
When the impurities introduced into the plating solution exceed the tolerance of the gold plating solution, the color and brightness of the gold layer will be affected quickly. If it is affected by organic impurities, the gold layer will appear dark and faint. Slice check dark and flower position
The setting is not fixed. If the metal impurities interfere, the effective range of current density will be narrowed. The Haoer trough test shows that the current density of the test piece is not bright at the low end or the high-end plating is not bright and the low end is not plated. The coating is red or even black, and its holes
The color change inside is more obvious.
Thirdly the current density is too large
Since the total area of the plated parts is incorrectly calculated, the value is larger than the actual surface area, so that the amount of gold plating current is too large, or the amplitude of the gold plating is too small when the plated gold is used, so that all or part of the gold plating in the groove is crystallized, and the gold is visually observed. The layer is red.
