Abstract
The disclosure describes soldering a first component (200) to a second component (226) for use in a downhole circuit, device and/or tool. The first component (200) includes an electrically conductive contact region (402) finished with a metallic finish layer (404). The soldering includes disposing a layer of manganese (408) adjacent to the metallic finish layer (404), and applying solder (406) to the layer of manganese (408). The solder (406) used in the soldering of the two components is a mixture of copper, silver and tin.
