Abstract
Abstract A surface mounting method which utilizes an adhesive component to mount the electrical components to a printed circuit board instead of solder and which includes the use, between the contacting surfaces, of a flowable, corrosion-resistant material which bridges contact imperfections and penetrates surface films. The method may also be implemented to connect two electrical conductors.
