How this two-layer aluminum PCB is constructed
This listing specifies two copper circuit layers with 2 oz copper and an aluminum base. Aluminum provides mechanical support and a heat-spreading path; it is not a substitute for the copper signal and power traces. An electrically insulating dielectric separates the circuitry from the metal base.
Confirm the stack drawing before ordering: the position of each copper layer, dielectric thickness, total finished thickness, hole isolation and the connection to the aluminum base must be defined. The stated 1.6 mm thickness and panel dimensions describe this catalogue example, not every two-layer aluminum construction.
What to provide for engineering review
Send the board outline, circuit files, copper requirements, operating voltage, dissipated power and the mechanical mounting arrangement. Thermal performance depends on the dielectric and its thickness, copper spreading, interface materials and the final heatsink or chassis. An aluminum base alone does not establish the allowable component temperature.
Review aluminum PCB construction options and PCB manufacturing requirements, or request a review of your stack drawing.
