PROCESS TO PRODUCE CONFORMAL NANO-COMPOSITE COATING FOR MITITGATION OF MANUFACTURING DEFECTS USING CHEMICAL VAPOR DEPOSITION AND NANO-STRUCTURES

摘要

The present invention relates application of conformal coatings made up of nano-fiber, nano-particle, and/or nano-capsule materials to be applied on electrical component parts in general and printed circuit boards (PCB) in particular. A conformal coating material, such as Parlyne, can be combined with nano-materials to produce desired results. Benefits of this invention include enhancement of conventional conformal coatings performance in terms of properties such as mechanical, electrical, magnetic and in particular to prevent or obstruct the growth of tin whiskers or any other manufacturing defect that can develop on the surface of a PCB.

主权项

1. A method of manufacture of a conformal coating comprising the steps of:
providing an electrical component; providing a first structure source, wherein the first structure source produces one or more first structures having a modulus of elasticity higher than a manufacturing defect of the electrical component; providing a chemical source capable of producing a chemical vapor; and depositing the chemical vapor and the first structures in a layering process on the electrical component such that a composite non-conductive mechanical barrier to extrusion or emergence of manufacturing defects arising from the electrical component is created, wherein said manufacturing defect comprises one or more crystalline metallurgical phenomenon involving a conductive spontaneous growth structure, wherein said first structures have a higher modulus of elasticity than said manufacturing defect, wherein the first structures are made up of a nano material such as nano-fiber, nano-capsules, or nano-particles which prevent or restrain formation or protrusion of undesirable manufacturing defect structures.
