Abstract
Abstract A template made of steel or other hard material is identical with a printed circuit card with respect to the locations of holes for receiving component leads to be soldered to the printed circuit cards. The template and card are sandwiched together at the start of production. Then, all components are mounted with their leads projecting through the bottom of the template. Thereafter, they are cut off flush with the bottom of the template. Next, the template is removed to expose the stub ends of the leads. Then a roller is run across the bottom of the card, and the leads are bent over into a presoldering position.

Claim 1
Independent Claim
146 words
A method of assembling components to printed circuit boards comprising the steps of: (a) placing and aligning a printed circuit board having plural substantially laterally spaced and longitudinally spaced conductor lined openings upon a rigid, reusable template having holes alignable with the openings on the board, (b) mounting components on the board with the component leads extending through the aligned holes and openings, (c) affixing a holding plate temporarily to said board to retain the components on the board, (d) applying a cutting member to the leads extending through the template, and in a single pass severing all the leads substantially flush with the bottom of the template, (e) removing the template from the board and, (f) bending over the extending cut leads and causing same to engage the bottom side of the board and the conductive openings by making a single pass with a roller.
