Plating circuit boards
WebbSoft, pure gold plating is used in the semiconductor industry. The gold layer is easily soldered and wire bonded. Its Knoop hardness ranges between 60 and 85. The plating baths have to be kept free of contamination. Soft, … PCB plating is applied to protect any copper in your PCB that would be exposed through the solder mask, whether it’s a pad, via, or other conductive element. Designers will often default to something like tin-lead (SnPb) plating, but other plating options may be better for your board’s application. Visa mer This PCB surface finish is probably the cheapest option, but it will not comply with RoHS due to use of lead in the plating finish. Immersion tin is a lead-free alternative that can be used in entry-level boards. Visa mer HASL was historically a very popular surface finish choice, but it is not as reliable as other plating materials. It is inexpensive and is available in a lead-free option, so it can be used as an entry-level plating option. Visa mer Given the disadvantages of SnPb and immersion tin, ENIG is now arguably the most popular surface finish in the industry. In this plating material, … Visa mer This organic water-based surface finish selectively bonds to copper to provide a highly planar surface finish. As an organic material, it is sensitive to handling and contaminants, … Visa mer
