a coating deposited on the at least one surface of the substrate, wherein:

the coating covers at least a portion of the plurality of conductive tracks; and

comprises at least one halo-hydrocarbon polymer; and

at least one conductive wire that is connected by a wire bond to at least one conductive track at a particular region of the substrate, the wire bond formed through the coating without prior removal of the coating such that the wire bond connects the at least one conductive wire directly to the at least one conductive track at the particular region and the coating abuts the wire bond at the particular region.

2. The printed circuit board of claim 1 , wherein the wire bond abuts the coating along a plane parallel to the at least one surface of the substrate.

3. The printed circuit board of claim 1 , wherein the wire bond is at least one of:

a ball bond; and

a wedge bond.

4. The printed circuit board of claim 1 , wherein the wire comprises at least one of:

gold;
