Read the status before relying on a claim.
| Status | What it establishes | What is still open |
|---|---|---|
| Official sources reviewed | The platform read the cited manufacturer pages and recorded their publication context. | Factory ownership, present capacity and order-specific suitability. |
| Manufacturer reported | A named statement or numerical value is present in the original source. | Independent confirmation, combined process limits and current availability. |
| Independently reviewed | A specific evidence record has a review scope, reviewer and date. | Anything outside that recorded scope; a single check is not a whole-factory guarantee. |
| Unclaimed listing | The platform created a research profile. | The manufacturer has not obtained account access or confirmed participation. |
A claim is only as useful as its evidence.
PCBVerified organizes company identities, technical capabilities and source material so buyers can make a more informed shortlist. A directory profile does not replace your supplier qualification process.
Company identity
We record the company identity source and review date. A website statement alone does not prove factory ownership or that manufacturing is performed in-house.
UL records and equipment
A reported UL file number is separate from a verified ownership check. Equipment claims require source evidence; an equipment list does not independently establish process yield or production availability.
Materials and capability limits
Material traceability evidence is reviewed within its documented scope. Layer, trace and drilling limits may refer to different product series. Confirm the exact combination through a design-for-manufacturing review.
What a sourcing dossier should contain
| UL ownership | File number, identified holder, relevant site and product scope, original record and review date. |
|---|---|
| Equipment | Machine type, make/model where supplied, site, supporting document and the process it supports. Outsourced steps must remain visible. |
| Materials | Manufacturer and grade, approved supply documentation and a link to the relevant production batch. |
| Capability | Production stage, board family, copper weight and separate line, space, drill and finished-hole definitions. |
Corrections and factory participation
Manufacturers can submit an application to identify an outdated source or provide additional documents. Publishing a correction, reviewing technical evidence and approving account access are separate actions. No status is upgraded simply because a company is listed.
What we do not assume
Missing information is not a zero. Public marketing copy is not a certification. Published profiles are not guarantees of quality, delivery or regulatory compliance.
