    摘要: 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.

    摘要: A strap comprised of a layer of magnetic material on a layer of nonmagnetic conductive metal comprises a self-regulating heater, which is wrapped around a length of heat recoverable tubing disposed around a terminal being terminated to a conductor wire, or a pair of wires being spliced. When energized, the strap generates thermal energy melting solder of a preform within the tubing, terminating the terminal to the wire, or the two wires together, and sealing the termination simultaneously. A plurality of terminals in a connector housing include solder tails extending rearwardly from the housing so that respective wire ends may be placed therealong within solder preforms within heat recoverable tubing therearound. A strap comprising a self-regulating temperature source is wrapped around the array of solder tails and wire ends and is energized to solder the array and seal the terminations. A high frequency alternating current induced in or transmitted to the magnetic layer of the strap causes the strap to generate thermal energy sufficient to melt the solder and shrink the tubing. The strap may have several layers and may be shapable to conform to the outer surfaces of the heat recoverable tubing lengths. A strap may seal an open end of a length of heat recoverable tubing having a sealant preform therewithin, when wrapped therearound and energized.

    摘要: A heater bar assembly intended for use in a soldering apparatus or the like has a laminated self-regulating Curie effect heater mounted on a rigid support member. The heater is rapidly heated in use up to its Curie temperature and maintained at that temperature during a soldering operation so that overheating does not occur and, on the other hand, cold joints are avoided. The heater is slightly resilient, or deformable, so that when it is brought into contact with the wires, it is deformed by the wires thereby increasing the area of contact with the wires. A complete integrated soldering apparatus incorporating the heater bar assembly is also described.

    摘要: Soldering of surface mount connector terminals to contact pads on a circuit board is facilitated by configuring the terminals and their solder tails as spaced integrally-formed projections of a selectively actuable heater. Thermal energy developed in the heater is conducted along the projections to the solder tails to melt fusible conductive material (e.g., solder, at the connection sites). After cooling, the projections are severed from the heater. The terminals, which are formed at the distal ends of the projections, are typically supplied partially inserted in respective terminal-receiving passages of the connector housing. After the soldering operation, the terminals are fully inserted into the passages. The heater is preferably a self-regulating heater in the form of a copper substrate having a skin layer of magnetically permeable, high resistance material. An alternating current of constant amplitude and high frequency is passed through the heater and concentrated in the skin layer at temperatures below the Curie temperature of the skin layer material. At higher temperatures the current is distributed through the lower resistance substrate to limit further heating. During the time interval required for the surface layer to reach its Curie temperature, the resistive power dissipation creates thermal energy that is conducted to the solder tails.

    摘要: A self-redulanting heater includes an electrically-conductive substrate (11), having a magnetic surface layer (13) of one skin depth, folded 180 degrees to define two heater sections joined by a fold section. The magnetic material has a considerably higher resistance than the substrate material. The surfaces of the two sections clad with the surface layer are in closely spaced parallel relation and connected in series by the fold section (23) such that a constant amplitude alternating energizing current flows in opposite directions through the two sections at any instant of time to thereby establish an electric field between the two heaters. The field concentrates current flow at the two facing surfaces. Depth of the current is determined by the skin effect phenomenon and increases significantly at temperatures above the Curie temperature of the magnetic material.
