Abstract

A modified soldering iron tip has been developed that permits soldering of multiple solder joints simultaneously without solder bridging and without the need for precision solder volume control on printed wiring boards. Refer to the Figure for an illustration of the modified soldering iron tip.

Soldering Iron Tip

      A modified soldering iron tip has been developed that permits
soldering of multiple solder joints simultaneously without solder
bridging and without the need for precision solder volume control on
printed wiring boards.  Refer to the Figure for an illustration of
the modified soldering iron tip.

      Blade style soldering iron tip 1 is fitted with solder
unwettable adapter 2 which is secured to soldering iron tip 1 by
spring clip 3.  This creates alternate solder unwettable adapter
fingers 4 and solder wetted tip sites 5 on the working face of the
soldering iron tip 1.  Solder unwettable adapter 2 is loosely fitted
over solder wetted tip sites 5 such that molten solder can flow under
the unwettable adapter fingers 4 which creates reservoirs of equal
solder volume at each solder wetted tip site 5.  Solder is fed to the
soldering iron tip through the openings in solder unwettable adapter
fingers 4.

      Proper material selection for solder unwettable adapter 2
preculdes hard contact by soldering iron tip 1 during soldering which
protects components and printed wiring boards from mechanical damage
or burns.
