| abstract | (57) [Summary] (Modified) [Purpose] The adhesion of jumper circuits, through-hole circuits, and electromagnetic wave shields to the circuit pattern is increased to improve conductivity, eliminate bleeding during printing, and improve flex resistance. Improve. [Structure] The circuit pattern 1 has Zr 0.01 to 0.05% by weight, Cr 0.01 to 0.05% by weight, and the balance being substantially Cu, and is excellent in bending resistance and more conductive than pure copper. It is formed from a copper alloy rolled annealed foil that is comparable. The electromagnetic wave shield 7 and the jumper circuit 6 are made of a conductive coating material which is surface-coated with titanate and contains metallic copper powder, a resol type phenol resin, a chelate layer forming agent, an adhesion improving agent, and a conductivity improving agent. The through-hole circuits 5a and 5b are composed of metallic copper powder, resol-type phenol resin, thixotropic adjusting agent, amino compound, surface-coated with titanate, It is formed of a conductive paint containing a chelate layer forming agent. |
