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 32 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 receive bare end portions of conductors 36 inserted into slots 28 thereof. The device 10 and the conductors 36 disposed therein are placed on the board 50 with the respective conductors 36 opposed from respective contact pads 52 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 32 disposed therealong thereby electrically and mechanically interconnecting the array of conductors to the contact pads 52. The heater body 14 is then detached from the fingers 20 thereby electrically isolating the interconnections.
