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 different needs, our factory can produce ceramic circuit boards using various processes. We can handle traditional processes with layer counts ranging from 2 to 8 layers, utilizing low-temperature co-fired ceramic (LTCC) and high-temperature co-fired ceramic (HTCC) technologies to achieve layer counts of 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.
