The construction of Hybrid aluminum PCB
In fact, there were few MCPCB guys know the construction of hybrid aluminium PCB.
Even some of them know this type PCB.
In a ‘Hybrid’ aluminum PCB construction a “Sub-assembly” of a non-thermal material is processed independently and then bonded to the aluminum base with thermal materials.
Typical Hybrid aluminum PCB introduces
Due to hybrid aluminium PCB were not used widely, just use by some high tech companies.
So there were necessary introduce the typical Hybrid aluminum PCB.
The most common construction is a 2-Layer or 4-Layer Sub-assembly made from conventional FR-4.
The benefit of Hybrid aluminum PCB
When designed with an adequate number of thermal was this construction is less costly than one composed of all thermally conductive materials, but still provides superior thermal performance over a standard FR-4 product.
