HDI PCB Manufacturer in China
High-density interconnect boards with blind and buried vias, made to order at factory-direct prices — every stack-up reviewed by our process engineers, free of charge.
HDI PCBs pack more routing into less space using blind and buried via structures, letting designers fit fine-pitch BGAs and dense component layouts onto smaller boards. Our five LDI direct-imaging systems are the hardware behind the 0.075 mm (3 mil) fine-line capability that HDI routing depends on.
We manufacture HDI boards to order and review each stack-up case by case. Send your Gerber and stack-up files for a factory-direct quote and a free DFM review before production — the same flying-probe and 100% electrical testing that covers our standard boards applies here too.

Common Questions
How do I get an HDI PCB quote?
Email your Gerber and stack-up files with quantity and requirements to sales@yz-pcb.net. You get a factory-direct quote and a free DFM review within 24 hours.
My stack-up is unusual — can you build it?
Send the files anyway. Every HDI stack-up is reviewed case by case by our process engineers, free of charge, before any commitment.
Do HDI prototypes need a test fixture?
No. With 12 flying-probe testers in-house, prototypes and small batches are electrically tested without building a dedicated fixture, and every board ships 100% electrically tested.
Do you ship overseas and support English communication?
Yes — worldwide delivery by express courier or sea freight, EXW/FOB terms with T/T payment, and English-speaking sales support by email.
