How It's Made
Manufacturing Process
High-precision ceramic fabrication with state-of-the-art laser and plating tech
01
Substrate Sourcing
Selection of high-purity Alumina or Aluminum Nitride. Substrates undergo ultrasonic cleaning and surface treatment to ensure bonding quality.
02
Laser Drilling & Scripting
Using CO2 or UV lasers to drill high-precision through-holes and scribe individual boards with micron-level accuracy.
03
Metallization (DPC/DBC)
Thin-film deposition (DPC) or high-temperature bonding (DBC) to create robust copper layers on the ceramic surface.
04
Patterning & Plating
Fine-line circuit imaging followed by electroplating and high-end surface finishes like ENIG or Electrolytic Gold.

FAQ
What certifications do PCB factories have?
All of our products are IPC rated with ISO 14001; ISO 9001; CE; ROHS certificates, etc. Our products are widely used in communication, medical equipment, industrial control, power supply, consumer electronics and aerospace, automotive industry and other fields.
How many layers is a Ceramic PCB？
According to the different needs, different processes, our factory can do ceramic circuit boards, can do the traditional process layer 2-8 layers, using low temperature co-fired ceramic (LTCC) and high temperature co-fired ceramic (HTCC), can reach 10-20 layers, or even higher. In actual application we will choose according to the customer, the type of process required and demand.
Commonly used ceramic circuit board processes
Using the common ceramic circuit board thick film process, it is an advanced printed circuit board manufacturing technology with the advantages of easy multi-layer wiring, low cost, high temperature resistance, corrosion resistance, good mechanical strength, etc., which is widely used in the fields of electronics, communications, aerospace and so on.
Is it possible to produce a ceramic PCB with only a picture and no Gerber file?
We can't produce without gerber file, we produce based on Gerber. Or if you have any samples, we can also clone based on the samples, if so, we can send 3-5 samples to our company, and then evaluate the price of making samples for you.
What is your delivery time?
The fastest delivery time we can support is 12 hours. 1 hour for prompt quotation. 4 hours for prompt engineering. This depends on your product requirements and quantity. In addition, lead time will be included in your quote.
Where are your circuit boards manufactured?
As a global PCB manufacturer, our factories are located in Guangzhou, China and Shenzhen, China, utilizing the strengths of each region to best serve you.
