Abstract

Abstract A method of manufacturing a base for the envelope of an electric component, for example a semiconductor device, in which a pressure member is provided on one side in the cavity of a jig, which cavity has an approximately rectangular cross-section, after which a member of insulating material which softens upon heating is placed on the pressure member from the other side where a chamber of a larger cross-section is present which communicates with the cavity, after which of a conductor grid the conductors of which are supported at one end by a strip and are bent at their other end transverse to the plane of the grid the ends connected to the strip are inserted into a narrow slot between the pressure member and the wall of the cavity until the bent ends of the conductors bear on the insulating member after which the chamber is closed by a closure plate, the jig is heated and a force is exerted via the pressure member, in which the bent ends of the conductors are forced against the closure plate by the insulating member and a part of the softened insulating material is forced between the conductors in the direction of the side walls of the chambers so that a base is formed the bent ends of which of the conductors are situated on the upper side of the insulating member and the parts of the conductors connected thereto with are embedded in the insulating material and the further part of the conductor project from the lower side of the insulating member.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 172 words
A method for making a base for an electric component, comprising the steps of: forming conductive strips each having a transversely bent over portion near one end thereof; spacing the strips around a block of heat softenable insulating material having a top surface, a bottom surface, and a side surface, each strip extending along the side surface to and beyond the bottom surface with the bent over portion partially covering the top surface; heating the block of insulating material until suitably soft; while the block is soft, compressing the block between a first solid surface covering the top surface of the block and a second surface covering the bottom surface of the block, whereby the bent over portion of each strip is pinched and held between the first surface and the top surface of the block while soft insulating material from the side of the block is squeezed through the spaces between the strips; and molding to a suitable shape the soft insulating material which squeezes through the spaces between the strips.
Claim 2
Independent Claim 172 words
A method for making a base for an electric component, comprising the steps of: forming conductive strips each having a transversely bent over portion near one end thereof; spacing the strips around a block of heat softenable insulating material having a top surface, a bottom surface, and a side surface, each strip extending along the side surface to and beyond the bottom surface with the bent over portion partially covering the top surface; heating the block of insulating material until suitably soft; while the block is soft, compressing the block between a first solid surface covering the top surface of the block and a second surface covering the bottom surface of the block, whereby the bent over portion of each strip is pinched and held between the first surface and the top surface of the block while soft insulating material from the side of the block is squeezed through the spaces between the strips; and molding to a suitable shape the soft insulating material which squeezes through the spaces between the strips.
Claim 3
Dependent Claim 28 words
The method of claim 1 wherein the forming step comprises forming a grid of parallel spaced conductive fingers having a transversely bent over portion near one end thereof.
Claim 4
Dependent Claim 55 words
The method of claim 2 wherein the spacing step comprises positioning the grid adjacent a block of heat softenable insulating material having a top surface, a bottom surface, and a side surface, the grid extending along the side surface to and beyond the bottom surface with the bent over portion partially covering the top surface.
Claim 5
Dependent Claim 16 words
The method of claim 1 wherein the molding step includes maintaining the position of the strips.
Claim 6
Dependent Claim 16 words
The method of claim 1 wherein the compressing step includes maintaining the position of the strips.
Claim 7
Dependent Claim 11 words
The method of claim 1 wherein the insulating material is glass.
