摘要:
A process for quantitatively measuring one of the surface tension components for a solder-flux combination by introducing a gaseous ambient bubble internally coated with a liquid flux into a molten solder, and measuring a pressure differential.
摘要:
A zero-insertion force connector comprising a supply means for providing a thermal source and a base means adapted to support one or more pairs of mating contacts. A reversible motion actuator means comprising a temperature responsive nickeltitanium alloy is adapted for connection to the mating contacts. The actuator means is selectively responsive to the thermal source for opening the mating contacts for providing zeroinsertion force for an electrical interconnection package having one or more pairs of electrical contacts thereon.
