| titleOfInvention |
Flexible polyimide circuits having predetermined via angles |
| abstract |
A flexible circuit having a polyimide substrate containing at least one chemically etched feature, wherein such etched feature has sidewalls having a predetermined slope angle. It is possible to create etched features having predetermined slopes of from about 10 to about 70 degrees. Preferably, the flexible circuit was formed from a polyamic acid containing multiple ester groups in its main polymer chain. |
