FR4 Microwave Frequency PCB

The most mc pcb is aluminum pcb, aluminum has good heat transfer and dissipation ability, but also cheaper than copper based pcb.many customers asked a quote for mc pcb but without the thermal.requirements.if you know the thermal conductivity is the most most important thing for mc pcb,then you will know why the price is so difference.
