Significance and Use
7.1 The electrical and mechanical characteristics of circuits produced from flexible composites of copper foil with dielectric materials will, to a large extent, depend on the properties of the dielectric portion of the composite. Measurement of these properties is essential for predicting performance of the circuit.
1.1 These test methods cover procedures for testing flexible materials consisting of copper foil combined with either dielectric film or with treated or impregnated fabric to form flexible composites used in the manufacture of flexible or multilayer circuitry, or both.
1.2 The procedures appear as follows:
ASTM Reference Method

Flex Life of the Composite

Peel Strength of the Composite
| || |
Strain Relief Due to Etching
Testing of the Dielectric Portion of the Composite
