# EMS Suppliers, Verified

> An independent, source-linked directory of China-based electronics manufacturers for North American buyers. Every profile lists verifiable facts only — monthly capacity, process limits, board types or connector platforms, certifications with registry numbers, real lead times, MOQ, and public US customs shipment records — each with a link to its source. Free to browse. Manufacturers cannot pay to be listed.

Operated by Sichuan Zhiqi Technology & Culture Co., Ltd. (founded 2021, Suining, Sichuan, China — inside one of China's densest PCB manufacturing clusters). Contact: hello@emssuppliersverified.com

## Categories

- [PCB Fabrication](https://emssuppliersverified.com/pcb) — single/double-sided, multi-layer, HDI, rigid-flex, aluminum and metal-core, high-frequency laminates. Compared on capability ceiling, volume fit, certification scope, and export evidence.
- [Wire Harness & Cable Assembly](https://emssuppliersverified.com/wire-harness) — automotive, industrial, medical, overmolded and waterproof assemblies. Compared on connector platforms, wire range, test capability, workmanship class (IPC/WHMA-A-620), and export evidence.
- Further categories — connectors, sheet metal and enclosures, PCBA turnkey — will open as separate sections under the same fifteen-field standard. A new category is a new section, not a new website.

## How facts are verified

1. Company identity from the national enterprise credit registry, cross-checked against the company's own site.
2. Capability figures taken only when specific, not promotional.
3. Certification numbers looked up in the issuing body's public registry (UL, ISO/IATF via the certification body), never from a factory PDF alone.
4. Export evidence from public US customs bill-of-lading records — what the record shows, nothing inferred.
5. Every field carries the URL it came from; fields whose source disappears are removed at review.

## Reading the profiles

A blank field means "not confirmed from a public source" — not a negative rating. Many capable factories publish no capacity or certification data. No paid placement, no sponsored rankings, no customer names.
