HDI PCB manufacturers in China
ChinaPCB lists Chinese HDI PCB factories only after a public-source review; each profile states the microvia build-up structure, the source of the claim and the review date, so a buyer can shortlist on documented HDI capability instead of an advertised maximum layer count.
Last reviewed: Tue Nov 10. See how evidence levels work.
What HDI means on a factory profile
HDI boards use build-up layers and laser-drilled microvias, usually with blind or buried vias and finer trace geometry than a conventional multilayer board. A factory that builds a 1+n+1 stack is not automatically able to build 3+n+3 or any-layer HDI. Those are different process qualifications.
We therefore record the build-up structure, not a single headline layer count, and we keep it attached to the product series it was published for.
What we check before listing a factory here
- Whether the microvia structure is published by the manufacturer or supported by a qualification record.
- Whether via filling, laser drilling and sequential lamination are in-house or subcontracted.
- Whether the laminate and the via-fill process are stated for the same series.
- The date the claim was last checked.
A claim that only appears in a marketing paragraph is labelled as manufacturer-reported, not independently reviewed.
Factories in this category
No factory has cleared the hard-verification bar for HDI yet. When one does, this section will list its registered legal entity and production address, and record the microvia structure (stacked or staggered), build-up layer count, laser-drill capability and lamination cycles per product series, each with an evidence level and review date.
