Abstract:
A power measurement is made to determine completion of a proper soldering operation; in one embodiment by measuring peak power delivered to a level as a function of temperature, and in another embodiment the plot of peak power as a function of time.
Abstract:
A self regulating heater comprises a non-conductive, magnetic core (20) having a coil (22) wound about it and providing pole pieces (26, 28) extending into contact or very near contact with a surrounding ferromagnetic member (36) which in turn may be surrounded by and in intimate contact with a non-magnetic low resistance member (30); the magnetic member having an effective Curie temperature at the temperature to be maintained.
Abstract:
A Curie point heater primarily for use in a soldering iron and initially designed to operate with currents in the megahertz range is restructured to operate in the kilohertz range. Further in one embodiment of the heater, the coil exciting the heater is mounted in the handle of the iron.
Abstract:
A self-heating and self-soldering bus bar for use in many applications. The pins of the bus bar are quickly and directly heated to a predetermined autoregulated temperature without significantly raising the temperature of the body of the bus. Thusly a bus bar may be mounted while maintaining thermal balance and mechanical integrity of all wotk pieces. The present invention avoids the problems normally associated with excess thermal expansion experienced when a bus bar is heated incidental to the heating of its contact points. A majority of this incidental heating is eliminated by direct quick heating of the mounting pins.
