Aluminum Nitride PCB Manufacturer

Fx PCB is a professional manufacturer of Ceramic substrate PCB,  and we can make the ALN PCB(Aluminum Nitride PCB)  and AI203 circuit boards(Aluminum oxide board). FX PCB manufactures the ceramic PCB using DPC (Direct plate copper) technology, which will plate the copper directly into the ceramic substrate. The advantages of the DPC manufacturing process are high thermal conductivity, high precision of the traces, and reasonable cost.

Let us talk about the ALN(Aluminum Oxide board) here, the substrate is gray in color, while the AI203 is white.  The PCB  thickness can be 0.38-3.0mm,  Alumina substrate PCB size is 50×50 to 138*190mm. Its thermal conductivity is over 170.  So even the cost of ALN is more expensive than the AI203, it is still the best choice for customers’ products
