Abstract

By the use of U-shaped channel members across the top of a wave solder pot, critical parts, such as connector housing, etc., can be kept free of solder while circuit cards are conveyed over the solder or wave soldering. By the use of U-shaped channels, the time to attach and detach protective fixtures, which protect the housing from solder, is saved. Solder pot 11 includes molten solder 13 and a wave hump 15 which raises the solder in a localized area to contact the bottom of a circuit card being conveyed across the top of the soldered pot. Channels 17 and 19 are mounted to the top of the solder pot.

Fixtureless Wave Solder Conveyor System

By the use of U-shaped channel members across the top of a wave solder pot, critical parts, such as connector housing, etc., can be kept free of solder while circuit cards are conveyed over the solder or wave soldering. By the use of U- shaped channels, the time to attach and detach protective fixtures, which protect the housing from solder, is saved. Solder pot 11 includes molten solder 13 and a wave hump 15 which raises the solder in a localized area to contact the bottom of a circuit card being conveyed across the top of the soldered pot. Channels 17 and 19 are mounted to the top of the solder pot. As a circuit card is conveyed over the solder by a horizontal conveyor (not shown), the connector housings which are used to connect the circuit card to a circuit board and to other circuit cards or cables are protected because they travel in channels 17 and 19, as shown in Fig. 2. Although the solder does rise up and touch the bottom of the channel, the channels protect the housings from the solder. A multi-purpose conveyor finger mechanism is shown clearly in Fig. 2 for grasping cards having a housing at both edges or a housing at only one edge. If the card has no housing at its edge, the indentation 21 in the finger receives the edge of the card to support the card. When the card does not have a housing, channel 17 or 19 can be eliminated because solder will not stick to fingers 23 and 25.
