The short answer. Of sixteen measured Chinese PCB plants, five state a layer range on a page this directory could read: Champion Asia at 1–108 layers, Yingchuangli at 2–48, Jingming at 2–24, Suntak at 2–78 — for its Thai plant, which is under construction — and Kaishengshi at up to 10. The other eleven describe high-layer work in words and publish no number at all.
The inversion worth knowing. The plants with the most high-layer revenue disclose the least. Kinwong (¥15.31bn, a Zhuhai high-layer-count factory at full production), Victory Giant (¥10.73bn, boards for AI accelerator cards) and Shengyi (¥9.494bn, servers and supercomputing) publish no ceiling between them. The ¥2.5bn plant is the one that says 108 layers.
The distinction in the fourth column matters more than the number in the third. A range attached to a whole company is a marketing claim; a range attached to one factory is closer to a specification, because a stack-up is built on a line, not on a group.
| Plant | Where | Range stated | What the range is attached to |
|---|---|---|---|
| Champion Asia 骏亚科技 · 603386 | Huizhou | 1–108 | The group’s manufacturing range as described in its own 2025 annual report (pp. 33–34), across eight factories |
| Yingchuangli 英创力 · IQE | Suining | 2–48 | Its technical-capability table, checked 2026-11-01. A recruitment notice from the same company says 2–40 — two figures, one company, the site being the newer source |
| Suntak 崇达技术 · 002815 | Shenzhen | 2–78 | The Thai factory, under construction: 8-order HDI, 200,000 m²/month planned. No Chinese line has a stated ceiling |
| Jingming 景明 | Suining | 2–24 | Volume production claimed at the plant opening, per local trade press — not a document published by the company |
| Kaishengshi 凯盛石 | Suining | ≤10 | Company site, board-type list. This is a lamp-bar and automotive-lighting plant, not a high-layer shop |
| Suntak — 江门一厂 | Jiangmen | 4–12 | One factory’s page, alongside its published monthly capacity. The only case here of a range tied to a single building |
Read the Suntak row twice. The 2–78 figure that makes it look like the most capable high-layer plant in this directory belongs to a building that does not yet produce, while its Chinese high-layer factory in Zhuhai publishes a capacity — 120,000 m²/month, phase one — and no layer ceiling. A buyer comparing the two will get the wrong answer from the wrong document.
| Plant | Revenue | What it publishes about high-layer work |
|---|---|---|
| Kinwong | ¥15.31bn | A Zhuhai high-layer-count factory “at full production”, listed among thirteen factories. No ceiling, no capacity for that line, no HDI order |
| Victory Giant | ¥10.73bn (2024) | High-order HDI and high-layer boards for AI accelerator cards, AI servers, data-centre switches and 800G optics. Yields a 35% revenue increase and a 72% profit increase in one year — and states no layer count anywhere |
| Shengyi | ¥9.494bn | High-precision multi-layer for servers and supercomputing; revenue doubled in 2025. Explicitly publishes no layer count, no HDI order and no capacity in square metres on either language version |
| Xunjiexing | ¥689m | 信丰 #1 runs high-layer and HDI at 10,000 m²/month — a published capacity with no published ceiling |
| Glorysky | ¥1.152bn (2022) | Claims “high layer count” as one of four technology claims. No number, no capacity, no revenue since 2022 |
| Puruisen, Haiying, Zhichao, Hong'an Xingsheng, Shengda Xinxing, Wanyexing | ¥100–700m | Fine-line multilayer, HDI, or single/double-sided families. None publishes a layer ceiling; Zhichao publishes no website at all (its domain resolves for mail only) |
A layer ceiling is the least useful of the five numbers that decide whether a plant can build your stack-up, and it is the only one most plants publish. The other four are the laminate and its loss characteristics, the plating aspect ratio, impedance tolerance, and the registration capability at the layer count quoted. Only one plant in this directory publishes any of them: Hong'an Xingsheng states a plating aspect ratio of 10:1 and line/space of 3/3 mil (etch 2.5/2.5 mil) on a page that also admits a layer ceiling is not published. That is a vendor-stated, single-source figure — but it is a specification, which is more than the other fifteen offer.
The most detailed single board specification in the whole directory comes from a Suining plant rather than a Huizhou one. Jingming exhibits an 8-layer UAV main board with a 1+2+1 build-up on Shengyi S1000-2M laminate, TG170, minimum via 0.3 mm, 11/8 mil line/space, and a surface finish of electroless gold with OSP and resin-plugged blind vias. One board is not a capability statement, but it is checkable: a buyer can ask for the same board and compare.
Why the ceiling is a weak number: at 20-plus layers the constraints move from “can you laminate it” to “can you hold registration across 20 lamination cycles, and can you hit impedance on a loss-controlled material at the tolerance your SI team signed off”. A plant quoting 108 layers is telling you its equipment list, not its yield.
The 108-layer claim has no counterpart in the same document. Champion Asia’s annual report states 1–108 layers and, in the same filing, reports a net loss of ¥6.88m on ¥2.536bn of revenue. Capability and utilisation are different facts, and the second one decides your lead time.
Two of the five ranges are not about a Chinese line. Suntak’s 2–78 belongs to a Thai factory still under construction; Yingchuangli’s 2–48 contradicts its own recruitment notice (2–40). Ask which factory, and ask for the document, not the sentence.
Nobody publishes an impedance tolerance. Zero of sixteen. For a high-speed stack-up this is the number your design depends on, and it will only arrive in an email from a process engineer — after you ask for it in writing, with a coupon result.
Above all of them sits the material: which of these plants will name the laminate grade they buy, and who makes it. Two of sixteen name a grade — measured on the laminate layer.
The other process pages: HDI and any-layer · quick-turn prototype · IC substrate and SLP · metal-core, ceramic and heavy copper · FPC and rigid-flex. All six are indexed on capability by process, and the commercial questions — entity, certification, origin, order size — are on the buyer-question index.
