Evidence before claims
Every capability figure is tied to a source, an evidence level and a review date. Marketing maximums from different product series are never merged into one capability package.
Real PCB factories, verified
Find a real PCB factory in China, not another name on a list.
PCB and PCBA factories in mainland China, checked one by one. Find the factory that can actually build your board, read what it can prove, then contact it directly — no agent in between.
What a profile answers
- Who is the registered legal entity issuing the invoice?
- Which address actually runs the production line?
- Who holds the UL file, and for which site?
- Which process steps are subcontracted?
- When was each claim last checked, and against what source?
How the directory works
Verified factories. Direct contact.
ChinaPCB.org is a directory of checked PCB and PCBA factories in China. Before a factory gets a page we check the registered legal entity, the production address and the evidence behind its capability claims. A profile is built around the fields buyers actually compare — layer count, material, surface finish, certification and MOQ — each with an evidence level and a review date. Where something could not be checked, we say so instead of filling the gap. Read the profile, then contact the factory directly. No agent in between, and no request form that goes nowhere: enquiries reach us at info@chinapcb.org.
One entity, one page
A group parent, a trading company and a manufacturing subsidiary are three different things. We build a profile around the entity that actually makes the boards.
Nothing invented
Company names, certificate numbers, capacities and lead times are only published after they are checked. Unconfirmed fields stay visibly unconfirmed.
Browse by board type
Six board families, six different processes
A factory that builds multilayer boards well is not automatically an HDI or rigid-flex factory. Start with the process you actually need.
Aluminum PCB
Metal-core boards that use an aluminum base plate to move heat away from components, common in LED lighting and power conversion.
Open the categoryFlexible PCB
Circuits built on flexible polyimide film that can be bent or folded, used where a rigid board or a cable harness will not fit.
Open the categoryHDI PCB
High density interconnect boards built with build-up dielectric, laser-drilled microvias and fine lines instead of only mechanically drilled through vias.
Open the categoryHigh Frequency PCB
Boards built on low-loss RF laminates where dielectric constant, dissipation factor and impedance consistency drive performance.
Open the categoryMultilayer PCB
Three or more copper layers bonded into one board, used where routing density and controlled impedance make double-sided construction impractical.
Open the categoryRigid-Flex PCB
A board combining rigid sections and flexible sections in one laminated assembly, removing the connectors between the two.
Open the categoryWhat "verified" does and does not mean here
Public information can confirm that a company exists, that a UL file names a holder, and that a capability was published. It cannot, on its own, prove that a factory owns every production line it advertises. We separate those claims instead of blurring them together.

Read the guideCommon questions
Are the factories listed on ChinaPCB verified?
Every published profile carries one of four evidence levels and a review date. We check public records such as the business registry and UL files, but a listing is not a guarantee of factory ownership or in-house production.
Do you guarantee a factory owns its production line?
No. A website statement alone does not prove factory ownership or that manufacturing is performed in-house. We record which steps a factory says it owns and state clearly when that claim has not been independently checked.
How do I request a quote?
Email one technical package to info@chinapcb.org. The RFQ checklist lists the board data, materials, acceptance terms and supplier identity fields that make the replies comparable.
Can I correct a fact on a factory profile?
Yes. Send the profile URL, the field and a primary source to info@chinapcb.org; the correction is recorded on the profile together with its review date. The same contact is published on the about page.
