  • Horizontal soldering system with oil blanket
    Patent number: 5934540
    Abstract: A solder immersion chamber in a solder crater/leveler includes a solder manifold having upper and lower solder chambers, from which solder is directed onto the top and bottom surfaces of printed circuit boards conveyed therebetween. The solder immersion chamber has a pair of driven rollers at either end thereof for conveying the printed circuit boards through the solder immersion chamber, and for damming and holding the molten solder within the solder immersion chamber. A pair of oil weirs is provided adjacent either side of the upper solder chamber for continuously flowing oil to flood the top surface of the molten solder in the solder immersion chamber. A skimmer skims oil from the top surface of the molten solder, and returns the separated oil to the pair of oil weirs.
