1. A method, comprising:
- attaching a plurality of conductive tracks to at least one surface of a substrate comprising an insulating material;
depositing a coating on the at least one surface of the substrate, the coating covering at least a portion of the plurality of conductive tracks, the coating comprising at least one halo-hydrocarbon polymer; and
after depositing the coating, soldering through the coating to form a solder joint between an electrical component and at least one conductive track attached to the substrate, the solder joint abutting the coating; and
wherein;
the coating is deposited as a substantially continuous layer on the at least one surface of the substrate;
the solder joint is formed at a particular region of the substrate; and
the soldering removes the coating from the particular region of the substrate without removing the coating from other regions of the substrate.
