| Research Abstract |
Aromatic polymers such as polyimide and poly(oxybenzoate-co-oxynaphthoate) were modified with direct and remote plasmas, and the effects of the modification on the adhesion between the copper layer and the modified film surface were investigated for flexible printed circuit boards. The plasma treatment led to a noticeable decrease in the contact angle, which was mainly due to the C-O functional groups on the surfaces. The modification by the plasma was effective in improving the adhesion with copper metal. The peel strength for the copper/polymer system was enhanced from 10 to more than 500 mN/5 mm by the surface modification.
