One of the primary A very low cost, and also highly reliable system which drawbacks of using these coatings is that they do not can be used, involves the incorporation of a gold plated offer an interfacing resistance which is low enough to plate, which is reflow soldered to the PCB pad, thus facilitate the use of pressure contacts. Popular pressure providing an adequate interface.
