Abstract
A heat-recoverable soldering device comprises a heat-recoverable member containing a fusible solder insert, solder flux and a thermochromic composition which undergoes a visible change from a colored to a colorless state at the soldering temperature. Solderable substrates are positioned within the device and heat is applied until the soldering temperature has been reached, as indicated by a color change of the thermochromic composition. The soldering temperature is that temperature which is required to effect a solder joint between the substrates and recovery of the heat-recoverable member. Typically this temperature is at least about 20.degree. C. above the melting temperature of the solder.
