Base Thickness
Copper and aluminum Thermal Clad is normally purchased in one of
the standard-gauge thicknesses shown in the table below. Non-stan-
dard thicknesses are also available.
Electrical Connections To Base Plate
If a connection to the base plate is desired, copper is the most com-
patible base layer to use. When using electrical or thermal vias, it is
important to match the circuit and base coefficients of thermal TCE
expansion as closely as possible. Otherwise, excess plated-hole stress
will occur during thermal cycles. Other base layer materials can be
used for connection, but will require different connection schemes.
Costs
The most cost effective base layers are aluminum and copper
because they represent industry standards. Copper is more expensive
than aluminum when comparing the like thicknesses, but can be the
less expensive option if design considerations allow for a thinner layer.
As an example, typically the cost of 0.040" (1.0mm) copper is equal
to the cost of 0.125" (3.2mm) aluminum.
