Abstract
Abstract A device for connecting minute electric circuit elements with wire elements is disclosed. The connections are made by soldering, heat being supplied by an infrared lamp. A preinspecting system having an inspection head is provided. This system provides electrodes spaced to correspond to the spacing between circuit elements, which are utilized to evaluate the integrity of the electric circuit elements. A connection inspection system, using a bridge circuit is also provided. Open terminals of the bridge circuit are connected with a scanning device to determine the resistance of each element.
