Abstract
Electrical components, e.g., radiators, are made by a method comprising the steps of (1) providing a substrate, e.g., a polymeric film, having a first facial side that has a metal coating, e.g., copper, and a second facial side that does not have a metal coating; (2) applying an etch-resist to the metal coating to define a trace; (3) etching from the substrate the metal coating not covered by the etch-resist; (4) removing the etch-resist from the metal coating; and (5) plating, e.g., electroless plating, the uncovered metal coating with a plating material comprising at least one of silver, gold, and nickel.
Claims20
A method of manufacturing an electrical component that comprises a trace that comprises a contact spot, the method comprising the steps of:
- A. Providing a substrate having a first facial side that has a metal coating and a second facial side that does not have a metal coating;
- B. Applying etch-resist to the metal coating to define the trace of the electrical component;
- C. Etching from the substrate the metal coating not covered by the etch-resist;
- D. Removing the etch-resist from the metal coating;
- and
- E. Plating the uncovered metal coating with a plating material that comprises at least one of silver, gold, and nickel.
A method of manufacturing radiators on a polymeric film, the radiators comprising a trace, the method comprising the steps of:
- A. Providing a flexible, polymeric film having a first facial 'side that has a copper metal coating and a second facial side that does not have a metal coating;
- B. Applying etch-resist to the copper metal coating to define a plurality of discreet traces arrayed in a matrix comprising at least two rows;
- C. Etching from the film the copper metal coating not covered by the etch-resist;
- D. Removing the etch-resist from the copper metal coating;
- E. Electrolessly plating the uncovered copper metal coating with a substantially uniform thickness of plating material that comprises at least one of silver, gold and nickel;
- F. Applying a double-sided tape to the second facial side of the polymeric film;
- and
- G. Cutting the polymeric film and double-sided tape to form strips each of which includes at least one row of radiators.
