Abstract

The printed circuit board assembly system incorporates an improved method of fixing the terminal wires of the electronic components onto the board. The panel phenomena in the soldered section of the component wires is avoided. This method achieves more compact wiring and improves component density. The conducting area on the printed circuit board is not drilled. There are preset holes (4) which are formed by drilling through the insulating layer (12) so that one end of the holes concerned (14) will be sealed off by the conducting layer. The dia. of the hole is smaller than that of the component leads.
