Method for filtering a molten solder bath |
摘要 |
An apparatus for filtering a molten solder bath comprises, a housing having an entrance end and an exit end enclosing a channel means extending from the entrance end to a filter means adjacent the exit end. The channel means being configured for receiving molten solder at the entrance end and directing the solder to the filter means in a turbulent flow. The filter means being configured to filter particles from the flow and direct the filtered flow to the exit end. A cooling means is positioned on the housing for cooling solder flowing through the channel means without reacting with the solder. A method for filtering a molten solder bath comprises, directing solder from the bath in a turbulent flow and cooling the flow to form a precipitate of an impurity in the molten solder. The cooled flow is filtered to remove particles and form a high-purity solder, and the high-purity solder is returned to the bath. Preferably, the molten solder is protected by an inert atmosphere that does not react with the solder.
