  • Fabrication of thin film resistors and capacitors
    Patent number: 4385966
    Abstract: Disclosed is a method for fabricating a circuit including thin film resistors (15) and capacitors (12, 13, 14, 16) on a single substrate whereby stabilization is effected after all such components are completely formed. A high pressure steam atmosphere is utilized for stabilization so that the resistors can be stabilized at lower temperatures and/or times and the capacitors are not degraded.

  • Electronic component including soldered electrical leads
    Patent number: H498
    Abstract: Disclosed is an electronic component which includes soldered leads (30 and 31) for electrical connection to other components. The electronic component is typically a film or hybrid integrated circuit formed on an insulating substrate (10) which includes contact pads (20-23) on the periphery. Clip-on type leads (30 and 31) are soldered to these pads. The leads include a thin layer of nickel (36) formed at least in the jaw (32) of the clip-on lead to prevent the formation of brittle intermetallics by the interaction of solder components with the lead components.
