ABSTRACT:
A solder-bearing lead (10) includes a contact clamping finger (20) having an arcuate, reverse-bent clamping portion (34) which is wrapped about a solder preform (12) so that a surface portion (22) of the preform directly engages a contact pad (14) on a substrate circuit device (16) when the lead is mounted on the device. When the lead (10) is temporarily subjected to heat in a soldering operation, the solder preform (12) melts and flows directly over the contact pad (14) and then resolidifies to form a soldered connection (26) having an outer end portion (28) of the reverse-bent clamping portion (34) of the contact clamping finger (20) embedded therein.
