Technical requirements for Aluminum PCB
Main technical requirements:
Dimensional requirements, including board dimensions and deviations, thickness and deviation, verticality and warpage; appearance, including cracks, scratches, burrs and delamination, aluminum oxide film, etc.; performance, including peel strength, surface resistivity , minimum breakdown voltage, dielectric constant, flammability and thermal resistance requirements.
Special inspection method for aluminum-based copper clad laminates:
1.The dielectric constant and dielectric loss factor measurement method. It is a variable-Q series resonance method. The principle that the sample and the tuning capacitor are connected in series to the high-frequency circuit to measure the Q value of the series circuit;
2.The thermal resistance measurement method, which is calculated by the ratio of the temperature difference to the thermal conductivity between different temperature measurement points.
