Guide for Surface Coating Calculations

The amount of solids needed to coat a surface to a particular film thickness is the same regardless of the coating composition used Reducing the solids content of an organic solvent-borne coating increases the quantity of coating required and increases VOC emissions because more coating is used and the coating has a higher VOC content

Solderability

Nickel and gold are the most common plating choices Nickel is used alone and it is almost always used as under-plating for gold or tin These metals are plated on top of the nickel because they do not plate well directly to other base metals Nickel can be plated by an electrolytic or electroless process
