• Information：
A simple one layer MCPCB has 3 layers, the copper circuit layer, thermally conductive dielectric layer, and the metal core base layer. These three layers are then laminated together. The lamination technique bonds the three layers together providing a path for the heat to dissipate. Metal Core Layer This layer can be made out of aluminum, copper or steel. Aluminum is the most common due to its cost, weight and thermal characteristics. Typical thickness for aluminum is 1.0mm to 3.2mm and typical aluminum alloys used are: AL6061, AL5052, AL1370, AL770, and AL710. In some cases where heat dissipation takes priority over cost, copper is used for the base layer. Typically a heatsink is attached to the metal base to further dissipate heat away from the components. Dielectric Layer The dielectric layer is the most important layer in a MCPCB because it must maintain electronic insulation while also being thermally conductive. The dielectrics thickness plays an important role because it must be thick enough so the copper circuit does not short out, yet thin enough to maintain high thermal performance. Typical thickness of this layer is between 0.6mm to 2.0mm(.0024”-.008”). Thicker or thinner layers can be used depending on voltage and current. Copper Circuit Layer This layer is a traditional PCB circuit. The thickness can be anywhere between 35μm to 350μm (1 - 10 oz/ft2). A green or black solder mask coating covers the entire board to protect the circuit. Unlike PCBs a thicker copper layer can be used if the circuit requires higher current.
