Stripping and Soldering Process

The process is for stripping and soldering an insulated wire. There is a time- and temperature-controlled thermal cycle.

In one application, in the initial part of the cycle, a thermal pulse, which is at a high level and is of a relatively short duration, is applied to the insulated wire. It causes the insulation to melt and the solder to commence to flow. During the subsequent longer part of the cycle, the level of the thermal pulse is reduced leaving the solder in a wettable condition for effectuating the bond between the bared portion of the wire and a workpiece.

In another application, the process is used for stripping and pretinning an insulated wire. In the initial part of the cycle, a high-level thermal pulse is applied to the wire causing the insulation to melt. This is followed by a low-level thermal pulse which causes the molten solder to float away the melted insulation. In turn, the molten solder wets and adheres to the bared wire forming the pretinned coating during subsequent cooling.
