| titleOfInvention |
Flexible printed circuit board and process for its production |
| abstract |
The flexible print board contains as an insulating material a less heat-swelling resin having structural units represented by general formula (I), wherein Ar1? represents a tetravalent aromatic group, and Ar2? represents a compound of formula (II), (III) or (IV), wherein R1? to R8? may be the same or different and each represents a lower alkyl group, a lower alkoxy group or a halogen atom, and n1 to n8 each represents an integer of 0 to 4. This flexible board is produced by directly applying a solution of polyamidoimide precursor on a conductive substance and conducting imidation to form the insulating material of the less heat-swelling resin of the above-described general formula (I). The flexible printed circuit board undergoes less curling and has excellent adhesiveness, bending resistance, and dimensional stability. |
