Solder the pickup ground conductors to a potentiometer body wherever you find it to be most convenient. Bismuth solder is a low temp solder but then the surface treatment of the die is critical and most of these treatments are best done in wafer form. I've had good luck on closely-spaced solder connections by flooding the work with liquid flux; it's wasteful, but it prevents any oxidation, and solder bridges (that's what we called them) are less likely to happen, because surface tension stays healthy. to join (metal objects) with solder. Bridges can be caused by problems at various points in the assembly process. For example, you heat the metal of a component pin and the metal of a circuit board pad simultaneously, and then you touch the tip of the rosin-core solder to the pad or the pin, but not to the iron. The BGA device can warp during reflow causing adjacent BGA spheres to come in contact and form a solder bridge.
