Abstract:
1. A printed circuit board, comprising: a substrate comprising an insulating material; a plurality of conductive tracks attached to at least one surface of the substrate; a multi-layer coating deposited on the at least one surface of the substrate, the multi-layer coating covering at least a portion of the plurality of conductive tracks, the multi-layer coating comprising at least one layer formed of a halo-hydrocarbon polymer; and at least one electrical component connected by a solder joint to at least one conductive track, wherein the solder joint is soldered through the multi-layer coating such that the solder joint abuts the multi-layer coating; the solder joint is formed on a particular region of the substrate after a substantially continuous layer of the multi-layer coating is deposited on the substrate; and the soldering alters the multi-layer coating at the particular region of the substrate without altering the multi-layer coating at other regions of the substrate.
