Aluminum PCB is a type of ims substrate which made of metal-based copper-clad laminate with good heat dissipation function, and generally single-sided Aluminum PCB is composed of three Structural layers, namely the circuit layer (copper foil), the insulation layer and the metal base layer. For high-end use, there are also designs that are double-sided, and the structure is circuit layer, insulation layer, aluminum base, insulation layer, and circuit layer. Very few applications are multi-layer boards, which can be made of ordinary multi-layer boards laminated with insulation layers and aluminum bases.

The thermal conductivity of copper is as high as 386.4w/(m.k), which is an excellent thermal conductive material, and its performance is much higher than that of aluminum, and it has an absolute advantage in heat dissipation. In some products with extremely high requirements for heat dissipation, when the aluminum substrate cannot be satisfied, the copper PCB naturally becomes a better choice. SEEKPCB is a reliable copper PCB manufacturer that manufactures copper substrates for thermoelectric separation technology, and we have a wide range of copper and thermally conductive adhesives to provide quick turn copper PCB prototype service.

Iron PCB is a relatively rare metal circuit board, which is used in some special scenarios due to iron's good dimensional stability, heat dissipation, magnetic permeability, and acid and alkali resistance and moisture resistance. Generally, Iron PCB is divided into Ferrum based PCB and Stainless based PCB. These two different types of Iron PCBs have different applications, Ferrum based PCBs are generally used in brushless DC motors, laser printer motors, and Stainless based PCBs are used in subsea lighting or lighting used in some harsh environments. Although Iron PCB is a relatively rare product, and SEEKPCB has the ability to produce IRON PCB, which enriches the customer's approach to PCB design to a certain extent. Of course, SEEKPCB can also be competent for other types of metal PCBs.Most importantly, SEEKPCB can provide the best metal circuit board solution to meet the technical, stability and cost challenges.
