ABSTRACT:
A device 10 usable in conjunction with a source of constant amplitude high frequency alternating current of known frequency for providing sufficient thermal energy to melt a fusible electrically conductive material 24 includes an integral member formed from strip 12 of a first metal having a carrier strip section 14 and a plurality of fingers 20 initially integrally coextending therefrom. The carrier strip section 14 further has a thin magnetic layer 18 thereon, transforming the carrier strip into a Curie point heater. The fingers 20 including end portions 22 having layers of solder affixed to opposite sides thereof are adapted to be inserted into apertures 36 defined through a first electrical article 30 from a first surface 32 to a remote surface 34 thereof and adjacent contact pads 40 thereon. The first and second electrical articles 30,46 are placed together with the respective contact pads 40,48 opposed from each other and separated by the finger end portions 22. Upon subjecting the heater body 14 to the constant current of known frequency, the heater body 14 generates and transfers sufficient thermal energy to the finger end portions 22 to melt the fusible material 24 disposed therealong thereby electrically and mechanically interconnecting the arrays of contact pads 40,48. The heater body 14 is then detached from the fingers 20 thereby electrically isolating the interconnections.
