US Patent:
4451000, May 29, 1984
Filed:
Jun 11, 1982
Appl. No.:
6/387462
Inventors:
David E. Stephens - Concord MA
Assignee:
Hollis Engineering, Inc. - Nashua NH
International Classification:
H05K 334
US Classification:
228 20
Abstract:
The present invention provides an improvement in a circuit board mass soldering apparatus wherein a circuit board is contacted with molten solder at a soldering station and excess solder is removed from the surface of the board while still molten by impingement of a high velocity heated gas stream thereon, by providing a substantially horizontal louvered exhaust system adjacent to and in advance of the mass soldering station, below the travel path of the boards. The louvers extend and open into the path of the effluent gas stream such that the momentum of the gas stream carries it and entrained soldering fumes and particulates into the louvers to the underside thereof from which it may be exhausted by conventional means.
