Abstract: PURPOSE:To prevent the solder pool, solder dripping and hole clogging in the projecting parts on a chassis surface by inclining the chassis in such a manner that the respective ridges of the chassis are made non-parallel with the solder surface then pulling up the chassis in the stage of passing the chassis through the floating film of a flux and taking the same to the outside. CONSTITUTION:The solder 2a in a solder melting vessel 1 is held at a prescribed temp. and the oxide film of the surface 2b is removed, then the chassis 5 is dipped into the tank 1. The chassis 5 is inclined as shown A so as to bring the point P of the chassis corner into contact with the solder surface 2b and is dipped in this state into the solder in an arrow Y direction. The flux coated on the chassis 5 detaches from the surface 5 and floats on the solder surface 2b on the tank 1, thus forming the floating film 6 of the flux as shown in B. The film 6 does not diffuse to the outside of a diffusion-preventive frame. While the chassis 5 dipped in the solder is kept inclined as shown in C, the chassis is passed through the film 6, is pulled up in the arrow X direction and is taken to the outside as shown in D. The molten solder sticking to the chassis 5 flows down along the ridges of the chassis 5 as shown by an arrow and no inconveniences are generated.
