High Frequency PCB manufacturers in China
ChinaPCB identifies Chinese factories that name a specific Rogers or PTFE laminate system and publish their Dk control and insertion-loss test method, which is a more useful signal than a generic high-frequency capability claim.

Rogers and PTFE laminate capability
Which Chinese factories can produce Rogers high-frequency boards is a question about a named material system, not about a category label. A profile is useful only if it says which laminate series the factory has qualified, whether the board is a pure RF stack or an FR-4 hybrid, and how dielectric constant and insertion loss are verified.
We record the laminate per layer on hybrid stack-ups. A factory that has qualified one Rogers series has not automatically qualified every PTFE-filled or hydrocarbon-ceramic material, and we do not write the two as one capability.
What we check before listing a factory here
- The specific laminate series, not just “Rogers” or “high frequency material”.
- Whether the stack-up is pure RF or a hybrid with FR-4, and which layers use which.
- The published Dk tolerance and the insertion-loss test method.
- Whether the factory holds the material handling and etching process in-house.
- The source of the claim and the date it was last checked.
Factories in this category
No factory has cleared the hard-verification bar for high-frequency boards yet. When one does, this section will list its registered legal entity and production address, and record which laminate series the factory has actually qualified, the Dk/Df test method used, and the evidence level and review date for each claim.
