Common Surface Treatment Processes

Surface treatment purposeThe most basic purpose of surface treatment is to ensure good solderability or electrical properties. Since copper in nature tends to exist in the form of oxides in the air, it is unlikely to remain as raw copper for a long time, so other treatments of copper are required. Although in the subsequent assembly, strong flux can be used to remove most of the copper oxide, the strong flux itself is not easy to remove, so the industry generally does not use strong flux.Common ...
