Abstract

A method is described to minimize cost in some cases when engineering rework is necessary on printed circuit boards. At times it is possible to assemble a small printed circuit card with an engineering change on it and join it to the original assembly. This method saves the time and cost used to connect the parts with individual wires. The small card has printed pads adjacent to the component leads. To assemble the change to the original, first register the small card then fix it in place with adhesive. Then place solder fillets, and finish with a very small number of wires.
