METHOD OF ENCAPSULATING END-CONTACTED ELECTRICAL COMPONENTS

摘要

A method of encapsulating an end contacted electrical component, provided with connecting wires, with a continuous layer of synthetic resin material serving as insulation and protection, by a vortex sintering process by attaching a metal foil to the component or wrapping the component with a metal foil or a metalized synthetic resin foil with the metalization facing outwardly, in such a manner that no electrical contact is formed between the end contacts and thereafter placing the wrapped component in a reservoir containing a suspended synthetic resin powder maintained in a turbulent motion and heating the component indirectly by inductance using high frequency current so as to fuse or sinter resin powder deposited on the component to form the synthetic resin layer, the heating being conducted only after the component has been placed in the reservoir.
