HDI PCB
Engineered for fine-pitch components, compact layouts, and high-density interconnection.
LEARN MORE >>Multilayer PCB
For complex designs that need stable signals, dense routing, and solid layer-to-layer connections.
LEARN MORE >>Rigid-Flex PCB
Joins rigid and flexible circuits so the assembly can drop connectors and save space.
LEARN MORE >>Flex PCB
Ideal for lightweight, bendable, space-constrained products where rigid boards cannot fit.
LEARN MORE >>Metal Core PCB
Moves heat away from high-power LED, automotive, and power-conversion boards.
LEARN MORE >>High Frequency PCB
Low-loss materials for RF, microwave, and high-speed designs with strict impedance control.

What are our core advantages as a one-stop PCB & PCBA provider?
PCB fabrication and PCBA assembly sit under one inquiry, so you deal with one team, one set of files, and one schedule. We cover multilayer, HDI, high-frequency and high-speed, high-Tg, heavy copper, metal core, rigid-flex, and mixed-dielectric boards, from prototype to volume.
Can you support both prototypes and batch production?
Yes. We support prototype development, small-batch production, and volume manufacturing. Put the quantity you need in the quote form and the quote will reflect it.
What files do I need to provide for a PCB quotation?
Gerber files, drill files, BOM if needed, drawings, material requirements, surface finish, board thickness, copper thickness, quantity, and other project details.
Do you have a Minimum Order Quantity (MOQ)?
Our standard listings start from 10 pieces. If you need fewer, for example for a prototype, send your files and we will confirm what is possible.
How do you control quality?
Every order passes incoming material inspection, engineering review, production, testing, final inspection, and shipment. Our quality management system is certified to ISO 9001:2015, ISO 13485:2016 (medical-device PCBA), and IATF 16949:2016 (automotive PCBA).
How can I request a PCB quote?
Use the quote form with your files, specification, quantity, and project requirements. The team reviews it and replies.
Can you sign a Non-Disclosure Agreement (NDA)?
If your project needs one, tell us in the inquiry and we will arrange it before you share your files.
What files do you need for a complete PCBA quote?
Gerber files, the BOM, and a pick-and-place (coordinate) file.
What is your typical turnaround time for quotes and production?
Average production lead time is about one month in peak season and within 15 working days in the off season. With assembly, the time also depends on parts availability.
Can you handle full turnkey box-build assembly?
We provide PCB fabrication and PCBA assembly with testing. For box-build or enclosure work, send your requirements and we will confirm what can be covered.
Do you support alternative component sourcing for cost reduction?
Yes. Send your BOM and we will review it, suggest alternative parts where it makes sense, and confirm any substitution with you before use.
How do you handle shipping and global logistics?
We ship worldwide, with main markets in North America, South America, Europe, the Middle East, Southeast Asia, and East Asia. Shipping terms and carriers are agreed per order.
