Abstract
Abstract One or more leads are bonded to electrodes on a circuit board. Each lead has a first upstanding portion that extends away from a principal surface of the board and a second portion that extends parallel to that principal surface. The second portions are inserted through apertures in a block which is then inserted in an open ended case having a stair formed in its interior with the first portion of each lead clamped between the stair and a surface of the block.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
107 words
An encased micro-circuit comprising: a circuit board for mounting at least one electric element, said board having a plurality of electrodes thereon; a plurality of leads bonded to said electrodes, each lead having an upstanding first portion that extends away from a principal surface of said board and a second portion that extends parallel to said principal surface; a block defining apertures in which said leads are inserted; and a case in which said circuit board and said block are inserted, an inner wall of said case defining a stair, the first portions of each lead being held between said stair and the surface of said block.
Claim 2
Dependent Claim
107 words
An encased micro-circuit comprising: a circuit board for mounting at least one electric element, said board having a plurality of electrodes thereon; a plurality of leads bonded to said electrodes, each lead having an upstanding first portion that extends away from a principal surface of said board and a second portion that extends parallel to said principal surface; a block defining apertures in which said leads are inserted; and a case in which said circuit board and said block are inserted, an inner wall of said case defining a stair, the first portions of each lead being held between said stair and the surface of said block.
Claim 3
Dependent Claim
26 words
The micro-circuit of claim 1, wherein the second portion of each lead extends through a corresponding aperture in said block to the exterior of said case.
Claim 4
Independent Claim
124 words
A method for making an encased micro-circuit comprising the steps of: mounting at least one electric element on a circuit board having an electrode thereon; forming a lead having a first upstanding portion, a second portion extending at an angle to said first portion and a bonding portion; attaching said bonding portion to said electrode so that said first portion extends away from a principal surface of said circuit board and so that said second portion extends parallel to said principal surface; inserting said second portion through an aperture in a block; and inserting said block in a casing having a stair formed therein so that said upstanding first portion of said lead is held between said stair and a surface of said block.
Claim 5
Independent Claim
124 words
A method for making an encased micro-circuit comprising the steps of: mounting at least one electric element on a circuit board having an electrode thereon; forming a lead having a first upstanding portion, a second portion extending at an angle to said first portion and a bonding portion; attaching said bonding portion to said electrode so that said first portion extends away from a principal surface of said circuit board and so that said second portion extends parallel to said principal surface; inserting said second portion through an aperture in a block; and inserting said block in a casing having a stair formed therein so that said upstanding first portion of said lead is held between said stair and a surface of said block.
