Abstract
A chip mounting device which is hereinafter also referred to as an 'interconnection preform placement device', includes a retaining member having a predefined pattern of holes in which are positioned preforms of joint-forming material such as solder. Each preform is of a predefined configuration and has a height or length greater than is cross-sectional dimension. The preform retains its general configuration after the interconnection or soldering process to form a resilient joint which is more capable of withstanding stress, strain and fatigue. A method of forming resilient interconnections comprises placing the interconnection preform placement device between parallel patterns of electrically conductive elements, such as the conductive pads on an electronic component and a circuit board, and effecting the bonding of the conductive elements with the preforms.
