Bergquist Aluminum PCB: The aluminum PCB substrate is three layers, the top layer is copper foil for etching circuit, the following is a base metal, aluminum substrate metal layer is aluminum, the middle layer is the key technology of aluminum substrate, we call the high thermal insulation layer. If you look at the appearance, a variety of aluminum plate manufacturers are similar, the core performance of aluminum substrate is its thermal conductivity, thermal conductivity lies in the middle of the high thermal conductivity insulation layer.
Material /Laminate: Bergquist Aluminum
Board thickness: 2.0mm
Copper weight: 1oz
Finishing: LF HASL
Now, in the global electronics industry cooling solutions that the American Bergquist company do the best, the best thermal conductivity of aluminum substrate for the company to do is 2.2, in other words the thermal conductivity of the aluminum substrate that the global can reach is 2.2.
