Abstract
Abstract A method for the manufacture of transistors whereby groups of transistor lead wires are rigidly held during attachment of the transistor elements to the wires and are flexibly held during encapsulation of the transistor elements in a protective plastic nodule so as to prevent damage to the transistor elements due to thermal expansion.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
99 words
The method of manufacturing circuit element assemblies which comprises the steps of arranging each wire of a plurality of spaced parallel wires on a carrier strip so that the strip holds said wires in fixed relation to each other and the wires extend from the strip; attaching circuit elements to certain of said fixed wires; releasing said wires from said fixed relation so that the wires containing said elements are freed for limited movement relative to each other without removing the wires from the strip; by weakening the strip and then performing a manufacturing operation on said circuit elements.
Claim 2
Dependent Claim
22 words
The method as described in claim 2 wherein said manufacturing operation comprises encapsulating certain of said circuit elements in a protective covering.
