Method of manufacturing an improved microelectronic package
View Patent ↗A method of making a microelectronic package. The advanced microelectronic component package incorporates a specially shaped base element which holds and electrically separates the individual conductors associated with the microelectronic component(s) so that the individual conductors may be bonded to external package leads and other conductors within the package. In a first embodiment, jacketed, insulated wire is used as one winding of a toroidal transformer, while unjacketed insulated wire is used as another winding. The jacketing is stripped from the first winding and the exposed conductors are routed into channels along the sides of the base element. The unjacketed conductors are also routed into the same channels, where both conductors are bonded to the external package leads. Raised elements along the sides of the base provide the required electrical separation between the conductors during both manufacture and operation. A method of manufacturing the improved microelectronic package is also disclosed.
1. A method of manufacturing a microelectronic component package composing:
providing a microelectronic component having a plurality of individual conductors;
forming a component base having at least one sidewall, at least one internal recess, said recess adapted to at least partially receive said microelectronic component, and a plurality of raised elements, said raised elements mounted at least partially on said at least one sidewall, adjacent ones of said raised elements forming channels defined by said adjacent raised elements and said sidewall, said raised elements further defining a cavity for at least partly receiving said conductors;
disposing said microelectronic component within said internal recess of said component base such that pairs of said individual conductors are disposed at least partially within respective ones of said cavities;
routing individual conductors of said pairs in respective ones of said channels so as to provide electrical separation between said conductors;
inserting electrical leads into respective ones of said channels; and
forming an electrical connection between said leads and respective ones of said individual conductors.
2. The method of claim 1 , wherein said microelectronic component is a transformer.
3. The method of claim 1 , wherein the act of forming a component base includes the formation of four sidewalls and a top surface.
4. The method of claim 1 , wherein the act of forming a component base includes forming more than one recess.
5. The method of claim 1 , wherein each of said plurality of conductors of said microelectronic component are insulated.
6. The method of claim 1 , wherein at least two of said plurality of conductors are jacketed for at least part of their length after the conductors are insulated.
7. The method of claim 6 , wherein said method further comprises removing said jacket during manufacturing.
8. The method of claim 1 , wherein the act of forming an electrical connection between said electrical leads and said conductors includes soldering at least one conductor to at least one electrical lead.
