FAQ
Q: How far is your factory from the nearest airport?
A: About 30 kilometers
Q: What is your minimum order quantity?
A: One piece is enough to place an order.
Q: How much does a PCB ceramic board cost?
A: The cost of a ceramic PCB board is significantly higher than that of a traditional PCB board. Ceramic boards are much more expensive than FR4 boards, so the price of ceramic PCB is substantially higher, generally more than three times that of traditional PCB. The cost of prototyping ceramic PCB also differs from that of mass production, with mass production being more cost-effective.
Q: How to quote a ceramic PCB?
A: The specific quotation depends on the drawings, process requirements, complexity, and the utilization rate of the ceramic substrate. Generally, aluminum nitride ceramic PCB are more expensive than alumina ceramic PCB due to their superior thermal conductivity. However, the exact quotation is subject to the evaluation of the provided data files.
Q: Can you provide samples?
A: We have the ability to quickly proof-sample PCB and provide comprehensive technical support.
