Abstract: A solder dross recovery module has gears and a waste collection chamber positioned within a solder pot. The gears are configured to draw in solder dross from a surface of molten solder stored in the solder pot. The gears apply pressure to the solder dross so as to separate solder from the solder dross. The recovered solder is returned to the molten solder in the solder pot. A resulting waste material is collected in the waste collection chamber.

Abstract: A solder supply system that judges whether a solder cup is set on a solder supply device. In a case in which it is judged that the solder cup is set on the solder supply device, reading a barcode by a barcode reader is allowed. In contrast, in a case in which it is judged that the solder cup is not set on the solder supply device, reading a barcode by the barcode reader is restricted. That is, reading a barcode by the barcode reader before the solder cup is set inside an outer tube is restricted, while reading a barcode by the barcode reader is allowed when the solder container is set inside the outer tube.

The solder pre-form may also have a plurality of holes between the cable and connector sides. In a method of use, flux is applied to the flux grooves and the solder pre-form applied to encircle the outer conductor which is then inserted into the connector body and the solder pre-form melted to complete the solder interconnection. Where holes are present, flux may be applied to the connector side, passing through the holes also to the cable side.

Abstract: A continuous hot bonding method for producing a bi-material strip with a strong bond therebetween is provided. The method comprises sanding a first strip formed of steel; and applying a layer of first particles, typically formed of copper, to the sanded first strip. The method next includes heating the first strip and the layer of the first particles, followed by pressing a second strip formed of an aluminum alloy onto the heated layer of the first particles. The aluminum alloy of the second strip includes tin particles, and the heat causes the second particles to liquefy and dissolve into the melted first particles. The first particles and the second particles bond together to form bond enhancing metal particles, which typically comprise bronze.
