Abstract:
A printed circuit board (10) and method of manufacture thereof is disclosed. The printed circuit board (10) includes a first substrate provided from a conductive layer (12) having disposed on a first surface (12a) thereof a cured adhesive layer (14). A semi-cured adhesive layer (16) is then disposed over the cured adhesive layer (14) and a second substrate (18) is disposed against the semi-cured adhesive layer (16).
Abstract:
A method of depositing a conductive material (20) on a surface of a printed circuit board (10) includes the steps of chemically treating at least a portion of a surface of the printed circuit board, disposing a resist layer (16) over the chemically treated surface (12), depositing a conductive layer (20) in the areas which are not covered by the resist (16), stripping the resist from the surface of the printed circuit board (10), and cleaning exposed chemically treated surfaces of the printed circuit board (10) to remove contaminants from the surface of the printed circuit board (10) which were introduced in the chemically treating step.
