METHOD FOR MANUFACTURING OF SINGLE- OR MULTIPLE-LAYER PRINTED CIRCUITS Russian patent published in 1997 - IPC

FIELD: electronics, in particular, design of printed circuits which use polymer or ceramics base and have at least one current-conducting layer which is produced on both sides by chemical or galvanic methods. SUBSTANCE: substrate surface of circuit to be manufactured is processed in solution of oxidizing agent. Then after removal of rest of oxidizing agent, substrate is immersed in solution which at least one monomer from range of pyrrole, furan, thiophene or their derivative(s). Then substrate is immersed in acid solution. This results in generation of polymer layer from polymerized or co-polymerized pyrrole, furan, thiophene or their derivative(s). After this, excess of said solution is removed and article surface is subjected galvanic or chemical treatment to produce metal coating. EFFECT: increased functional capabilities. 10 cl
