FAQ

Frequently Asked Questions

We offer Alumina (Al₂O₃), Aluminum Nitride (AlN), Silicon Nitride (Si₃N₄), Silicon Carbide (SiC), Beryllium Oxide (BeO), and LTCC substrates. Our engineers can help you select the best material based on your thermal, electrical, and budget requirements.

Using thick film processes we handle 2–8 layers. With LTCC and HTCC technologies, we can achieve 10–20 layers or more. The optimal layer count depends on your circuit complexity and application requirements.

We accept orders starting from 1 piece for prototyping. There is no strict MOQ — whether you need a single sample or full-scale production, we provide competitive pricing at every volume level.

Our facilities are certified to ISO 9001, ISO 14001, UL, CE, and ROHS standards. All products meet IPC specifications and are widely used in communication, medical, industrial control, aerospace, and automotive industries.

We require Gerber files for production. However, if you have physical samples, we can reverse-engineer and clone them. Simply send 3–5 samples to us, and we'll evaluate and provide a quotation for prototype production.

We support turnaround as fast as 12 hours for urgent orders — 1 hour for quotation, 4 hours for engineering review. Standard lead times depend on product complexity and quantity, and will be included in your quote.
