Aluminum PCBs by its own structure, has the following characteristics: the thermal conductivity is very good, one side of the copper, the device can only be placed in the copper. Cannot open electrical connection hole so as not in accordance with the single panel placed jumper.

Aluminum PCBs is generally placed placement device, switch tube, the output rectifier tube through the substrate to heat transfer out. The thermal resistance is very low, which can obtain high reliability.

Transformer using planar patch structure, but also through the substrate heat, the temperature rise is lower than the conventional. The same specification of the transformer using aluminum board PCB structure can get a larger output power.
