Ceramic PCB Manufacturer

As a Ceramic PCB manufacturer in China, FX PCB can provide the ALN(Aluminum oxide) and AIO203(Aluminum Nitride) Ceramic PCB, we can make ENEPIG, ENIG, Immersion silver surface, you can check the material datasheet and our capability from the below tables.

Ceramic PCB is actually made of electronic ceramic materials and can be made into various shapes.

The ceramic circuit board has the following characteristics: high-temperature resistance, high electrical insulation, low dielectric constant, low dielectric loss, high thermal conductivity, good chemical stability, and thermal expansion almost can be coefficients of components.

Description

What is the Ceramic PCB Substrate?

FX PCB listed two kinds of Ceramic PCBs, which are Aluminum Nitride Ceramic PCB and Alumina Ceramic PCB (ALN and ALO203) Properties for your reference:

BECAUSE OF ITS HIGH THERMAL CONDUCTIVITY, LOW ROUGHNESS, AND EXPANSION, Aluminum PCB (AL203) is the most popular ceramic material for Ceramic PCB. Meanwhile, the price is cheaper than the ALN and Beo.

 Alumina Ceramic PCB Materials datasheet:

Item Unit Value Test Standard
Color / White 3.2
Density g/cm³ ≥ 3.7 GB/T 2413
Thermal Conductivity 20℃, W/(m • K) ≥ 24 GB/T 5598
Dielectric Constant 1MHz 9~10 GB/T 5594.4
Dielectric Strength KV/mm ≥ 17 GB/T 5593
Flexural Strength Mpa ≥ 350 GB/T 5593
Camber Length‰ ≤2‰
Surface Roughness Ra µ m 0.2~0.75 GB/T 6062
Water Absorption % 0 GB/T 3299—1996
Volume Resistivity 20℃, Ω .cm ≥ 1014 GB/T 5594.5
Thermal Expansion 10-6 mm 20~300℃ 6.5~7.5 GB/T 5593

Even though the  ALN PCB will be more expensive than the AIO203, ALN has high conductivity, and the expansion coefficient matching Si, which makes the customers still choose it as the material for their products, here you can see the details for the ALN material properties.

The Technology for The Ceramic Circuit Board

There are four kinds of technologies: LTCC (Low-temperature Co-fired Ceramic), HTCC (High-temperature Co-fired Ceramic), DBC (Direct Bonded Copper), and DPC (Direct Plate Copper). It is the thick film technology for LTCC and HTCC, and it will have the problem of poor thermal conductivity, bad precision of the trace, and a surface that is not smooth. If you want to know more details about this technology, you can read here 

DBC and DPC have high thermal conductivity, as the copper foil is bonded or plated to the ceramic directly without any middle layer, However, DBC will have the problem of the microbubbles between the ceramic substrate and copper. FX PCB is using the DPC technology for all of our orders. Click here to get more Ceramic technology from us

Ceramic  PCB VS Fr4 Material

  • Better thermal expansion
  • Stronger and lower resistance metal film
  • Good solderability of the substrate and high operating temperature 5, Good insulation, and Low High-frequency loss
  • High-density assembly possible
  • It has a long life and high reliability in aerospace as it does not contain organic ingredients and is resistant to the cosmic rays

What’s kind of fields that the Ceramic PCB can be used in?

The ceramic circuit board is primarily used in the LED field, high-power semiconductor modules, semiconductor coolers, electronic heaters, power control circuits, power hybrid circuits, components, high-frequency switching power supplies, automotive electronics, communications, aerospace, and military electronic components
