Latest Patents
Hasegawa's latest patents include a method for recovering lead-free solder from printed circuit boards. This method involves sorting discarded printed circuit boards according to the alloying elements in the solder used. After sorting, the boards are heated to melt the solder, allowing for the collection of the molten solder. Another significant patent is a soldering method using a copper-containing lead-free alloy. In this method, members to be soldered, such as printed circuit boards with electronic parts, undergo flow soldering in a solder bath containing the copper alloy. When the molten solder level falls below a prescribed point, it is replenished with a material that has a lower copper content, ensuring that the solder bath's copper content remains substantially constant for prolonged flow soldering.
