Patent ID: 7713862

Claim:
A method for manufacturing a printed wiring board having one or more layers of a conductive pattern and an insulating pattern, comprising: forming a first insulating pattern on an insulating substrate; semi-hardening at least one of the insulating substrate and the first insulating pattern; forming a conductive pattern on the insulating substrate and/or the first insulating pattern, thereby providing a stack structure; forming a second insulating pattern on the conductive pattern; performing a thermal treatment on the stack structure to fully harden the semi-hardened insulating substrate, the first insulating pattern and/or the second insulating pattern; and firing the conductive pattern, wherein the height of the second insulating pattern is the same as the height of the conductive pattern or higher than the height of the conductive pattern, and the insulating ink is a 2-component system consisting of 85-95 wt % of bismaleimide based compound and 5-15 wt % of photo-polymerization initiator.
