Abstract
A heat-recoverable soldering device comprises a heat-recoverable member having a fusible solder insert and associated with the solder insert, a solder flux composition which undergoes a visible color change at a critical temperature. Solderable substrates are positioned within the device and heated until a critical temperature has been reached as indicated by a color change in the flux. The critical temperature depends on the material of the particular heat-recoverable member and the solder used. It is that temperature which is required to effect a solder joint between the substrates and recovery of the heat-recoverable member. Novel flux compositions and their use in soldering are also disclosed.
