Procedure

A copper formate/citric acid solution was prepared by combining 3 ml of a saturated copper formate/water solution with 1 ml of a two percent by weight solution of citric acid and water. The solution was applied to a polyimide substrate and exposed to a Nd:YAG laser in the manner described above to produce copper lines having a cross-section of about 20 μm in width 5 μm in height. These copper lines were of comparable quality to the ones mentioned in the examples above.
