ABSTRACT:
A flexible circuit 10 panel is coated with solder by lowering into a bath of molten solder 4. On removal from the bath excess solder is blown from the panel by air jets from one or more nozzles 22. The panel is pulled towards the nozzle by a region 60 of negative pressure associated with the nozzles, and is held close to the nozzles to obtain an even coating of solder.
