ABSTRACT:
A grid array 10 of terminals 20 secured with a fusible electrically conductive material 34 usable in conjunction with a source of constant amplitude high frequency alternating current of known frequency is formed by the steps of: selecting a plurality of terminals 20 having a thin magnetic layer 30 defined thereon, transforming the terminal into a Curie point heater, each terminal 20 including a first connecting section 24 having a fusible electrically conductive material 34 disposed thereon; releasably holding each of the terminals 20 precisely positioned within an array 22 corresponding to an array 14 of circuit termini 16 of a circuit bearing article 12 such that each of the first connecting sections 24 of the terminals 20 is substantially in physical engagement with a corresponding circuit terminus 16; interposing an electrical conductor 60 connected to the source of alternating current among and adjacent each terminal 20 positioned within the array 22; subjecting each heater body to said constant current of known frequency, the heater body resultingly generating and transferring sufficient thermal energy to melt the fusible material 34 thereby electrically and mechanically interconnecting the terminals 20 to the respective circuit termini 16; and releasing the terminals 20.
