Ceramic Substrate Manufacturers

DPC (Direct Plate Copper) is a thin-film manufacturing process that deposits copper directly onto the ceramic substrate using physical vapor deposition and electroplating. Unlike conventional methods, DPC eliminates microbubbles at the copper-ceramic interface, resulting in superior thermal conductivity, tighter trace resolution down to 0.075mm, and better long-term reliability under thermal cycling conditions.

SFX PCB's ceramic PCBs are available with three surface finish options: ENIG (Electroless Nickel Immersion Gold), ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold), and Immersion Silver. Each finish offers excellent solderability and corrosion resistance. ENEPIG is particularly suitable for wire bonding applications common in semiconductor packaging.

Yes. Ceramic PCBs from SFX PCB are well-suited for aerospace and military electronics. The ceramic substrate contains no organic ingredients, providing inherent resistance to cosmic radiation. Material testing is conducted per Chinese national standards (including GB/T 3299-1996), and the boards offer high-temperature resistance, chemical stability, and thermal expansion coefficients that match semiconductor components.

Ceramic PCBs are available in standard thicknesses of 0.25, 0.38, 0.5, 0.635, 1.0, 1.5, 2.0, 2.5, and 3.0mm. Layer count supports 1-2 layer designs. Thickness tolerances range from ±0.03mm for the thinnest boards to ±0.05mm for boards up to 2mm, ensuring precise fit in tight mechanical assemblies.

Yes. SFX PCB offers turnkey PCBA services on ceramic substrates, including SMT and through-hole (THT) assembly, component sourcing from a pool of over 600,000 local stock items, and functional testing (FCT). Boards can be delivered assembled and tested, reducing your supply chain complexity and accelerating time to market.

SFX PCB accepts the most common PCB design file formats including Gerber, CAM, Eagle, CAD, Protel99, 99se, and DXP. This broad compatibility ensures a seamless order process regardless of your preferred EDA design tool. Their engineering team also provides free DFM (Design for Manufacturability) analysis to flag any issues before production begins.
