  • Solder connector device
    Patent number: 5350105
    Abstract: Composite solder articles contain a first portion of a first solder having a first melting point, T.sub.1, and a second portion of a second solder having a second melting point, T.sub.2, which is at least (T.sub.1 +10).degree. C. Such articles are useful as the sole solder-producing inserts in heat-recoverable solder connection devices. When the device is heated, the second solder will not melt until the first solder has melted and flowed. Thus the second solder portion can indicate when the first solder has flowed, and/or can control flow of the first solder.

  • Solder connection device
    Patent number: 5086967
    Abstract: A device for froming a solder connection between a plurality of elongate bodies comprises a dimensionally recoverable article, e.g. a heat-shrinkable sleeve, into which the bodies can be inserted, and a solder insert. The solder insert comprises two portions, one formed from a relatively low melting point solder for forming a solder joint between the bodies, and the other portion being formed from a relatively high melting point solder. When the device is heated the relatively high melting point solder will not melt until the low melting point solder has melted and flowed, and therefore provides a means for indicating that the correct temperature has been reached.
