Abstract

Abstract A ceramic chip capacitor is dipped in conductive termination paint so that there is a complete band of the conductive material all the way around the end of the chip and on the end surface. Leads having a nailhead type end that has larger overall dimensions than the end of the chip are soldered to the conductive end termination of the chip. A solder fillet forms all the way around the chip to the nailhead lead and extends over the edge of the chip producing a mechanical saddle all around the chip that provides an advantageously strong bond therewith.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 91 words
An electrical component having a lead assembly attached thereto comprising: an electrical component having at least one metallized end portion thereon; a lead assembly having at least one lead wire with a component contacting portion thereon perpendicular to said wire, said contacting portion having larger overall dimensions than said metallized end portion; and a soldered bond between said metallized end portion and said contacting portion, said bond is a solder fillet extending around the entire periphery of said metallized end portion and extending over the edges of said metallized end portion.
Claim 2
Dependent Claim 91 words
An electrical component having a lead assembly attached thereto comprising: an electrical component having at least one metallized end portion thereon; a lead assembly having at least one lead wire with a component contacting portion thereon perpendicular to said wire, said contacting portion having larger overall dimensions than said metallized end portion; and a soldered bond between said metallized end portion and said contacting portion, said bond is a solder fillet extending around the entire periphery of said metallized end portion and extending over the edges of said metallized end portion.
Claim 3
Dependent Claim 52 words
The electrical component of claim 1 wherein said component is a monolithic ceramic capacitor having said at least one lead wire in contact with, and extending outward from opposite metallized end portions thereof; and said component contacting portion of said at least one lead wire is in the form of a nailhead.
Claim 4
Dependent Claim 48 words
The electrical component of claim 2 wherein each of said metallized end portion is a band of silver completely around said end portion and end surface of said monolithic ceramic capacitor; said lead wire has a tinned outer coating; and said soldered bond consists of tin and silver.
Claim 5
Dependent Claim 25 words
The electrical component of claim 3 having a protective outer coating over said component, said soldered bonds and said contacting portions of said lead wires.
Claim 6
Dependent Claim 14 words
The electrical component of claim 4 wherein said protective coating is a molded material.
Claim 7
Dependent Claim 15 words
The electrical component of claim 4 wherein said protective coating is a fluidized bed coating.
Claim 8
Dependent Claim 109 words
An electrical component having a lead assembly attached thereto comprising: a monolithic ceramic capacitor having silver terminations completely around opposite ends and the end surfaces thereof; a lead assembly consisting of a pair of tinned lead wires, each having a component contacting portion thereon perpendicular to said wire, said contacting portion being in the form of a nailhead having larger overall dimensions than said silver terminations; and a tin and silver soldered bond between said silver terminations and said contacting portions of said lead wire, said bond is a solder fillet extending around the entire periphery of said silver termination and extending over the edges of said silver termination.
Claim 9
Dependent Claim 109 words
An electrical component having a lead assembly attached thereto comprising: a monolithic ceramic capacitor having silver terminations completely around opposite ends and the end surfaces thereof; a lead assembly consisting of a pair of tinned lead wires, each having a component contacting portion thereon perpendicular to said wire, said contacting portion being in the form of a nailhead having larger overall dimensions than said silver terminations; and a tin and silver soldered bond between said silver terminations and said contacting portions of said lead wire, said bond is a solder fillet extending around the entire periphery of said silver termination and extending over the edges of said silver termination.
