Occam process for components having variations in part dimensions
An Occam process (solderless manufacturing) that employs a component support fixture that provides permanent or temporary support for components during subsequent processing in a solderless process for electrically connecting the components to circuits. The component support fixture provides oversized compartments for housing the components which may have varying sizes. The compartments are provided with vent holes or apertures for venting air or excess glue as the component support is pressed against the components during manufacture.
1. A process comprising:
placing components having at least two heights or two widths or both defining a size range on an anisotropic adhesive substrate, wherein the anisotropic adhesive substrate comprises an adhesive film consisting of an anisotropic adhesive that is conductive in a direction vertical to the plane of the adhesive film, the adhesive film adhered to a metal foil; each component having at least one lead that contacts the substrate, the components adhesively attached to the anisotropic adhesive substrate without solder;
coating the components with an insulating material;
placing a component support fixture over the components, the component support fixture comprising oversized compartments surrounding the components, the size chosen such that the compartments accommodate components of all sizes with the size range; wherein the component support fixture comprises vent holes to permit venting of air or excess insulating material;
pressing the component support fixture until it contacts the substrate;
patterning the metal foil to provide an electrical connection to the at least one lead through the anisotropic adhesive.
2. The process according to claim 1 , further comprising pressing the component support fixture while the insulating material is still moldable thereby molding it.
