Questions & Answers
1.What is your lead time?
It usually takes 1–3 days for prototypes. For mass production, expect 7–15 days, depending on the order quantity and the design complexity.
2.How does MOKOPCB ensure the quality of alumina ceramic PCB?
We apply several inspection methods, such as automated optical inspection (AOI), x-ray inspection, in-circuit testing, functional testing, and flying probe testing.
3.Why choose Al2O3 material over other ceramic materials for PCBs?
Alumina is the most widely used ceramic material, offering a good balance of thermal conductivity, electrical insulation, and mechanical strength.
4.Where are aluminum oxide ceramic PCBs commonly used?
We can find aluminum oxide circuit boards in many industries, including aerospace and defense, automotive electronics, high-frequency electronics, etc.
5.Are alumina ceramic PCBs environmentally friendly?
Yes, alumina material is non-toxic and contains no harmful chemicals. It is an oxide of aluminum, which does not cause much pollution after disposal and can be recycled.
