  • Wave soldering in a protective atmosphere enclosure over a solder pot
    Patent number: 5176307
    Abstract: A short hood for enclosing and providing a protective atmosphere over not more than the solder pot of a machine for wave soldering printed circuit boards. Other operative areas of the machine are exposed to air. The entrance and exit openings to the hood for the circuit boards are covered by electrically conductive curtains of thin material cut into vertical strips. The process employs a thin layer of no-clean flux and allows up to 5% oxygen content in the protective atmosphere.
    Type: Grant
