Storage conditions
Aluminum PCBs are generally stored in a dark, dry environment. Most aluminum PCBs are prone to moisture, yellowing, and blackening. Generally, they should be used within 48 hours after opening the vacuum package.
Aluminium layer thickness
2 layers aluminum PCB substrate, copper thickness 1oz, aluminum base on the bottom of the laminate is probably like this for reference. The above parameters are basically unchanged. The thickness of the aluminum base is the thickness of the plate selected by the customer minus the thicknesses above.
