What this factory is. A STAR-listed (688655) PCB manufacturer in Bao'an, Shenzhen, incorporated in August 2005 and listed on 11 May 2021. Its business is not volume: it is the difficult middle of the market — prototype, then small batch, then production, without the customer changing factory. Three bases do different jobs: Shenzhen Shajing for custom prototypes with a 24-hour option, Xinfeng County in Jiangxi for high-layer and HDI plus a volume plant, and Zhuhai for a smart prototype plant that started production in the first half of 2025.
Why a buyer should look twice. Very few Chinese plants will quote a 2-layer prototype and a 12-layer production run from the same engineering file without a re-qualification. Xunjiexing's published claims are specific and checkable in kind: 10,000+ customers served, 130,000 prototype part-numbers a month, 280,000 m² a year of design capacity, certifications claimed for automotive (IATF 16949), medical (ISO 13485) and military (GJB 9001C). The 2025 accounts are the check that matters most, and they are not flattering.
What the record shows that the website does not. Revenue rose 45.21% to ¥689 million in 2025 and the company lost ¥22.4 million, with a 14.43% gross margin. That is a plant buying growth on thin spreads — typically the signature of a new base ramping (Zhuhai) and of prototype work priced to win volume. There is also no English-language website at all, for a company that took 21% of 2025 revenue from export customers.

The claim that matters is “no factory change from sample to production”. It is a genuinely unusual promise in this industry: most Chinese plants specialise by volume band, so a buyer's prototype house and their production house are normally different companies with different quality systems, which is exactly where hand-over defects come from. Xunjiexing inverts that by owning all three bands — Shenzhen for custom prototypes, Zhuhai for prototype volume, Xinfeng for high-layer/HDI and for volume.
The capacity numbers are internally plausible: 60,000 m²/month at Zhuhai plus 10,000 m²/month of HDI at Xinfeng #1 plus over 1,000,000 m²/year at Xinfeng #2 is roughly the stated 2.8 million m²/year group design capacity. What is not published: layer-count ceiling, minimum line/space on production panels, HDI order, copper weight ceiling, and the qualification required to move a part-number from the prototype line to the volume line without a new first article.
The 14.43% gross margin is the number a buyer should read as a capability statement rather than an accounting one. Prototype work carries high engineering content and low material volume; if the mix is drifting toward volume at prototype prices, the margin falls exactly like this. Ask what the margin is on the specific band your order sits in.
Four anchors: a STAR listing with audited accounts since 2021, a 20-year operating history, a four-system certification claim that spans automotive, medical and military (the last is unusual and implies a traceability discipline that commercial work does not), and a sitemap with 208 real URLs — a plant that maintains its own site, whatever it fails to publish there.
One anchor is missing and one is negative. Missing: certificate numbers with scope, which matters most for the IATF and GJB claims. Negative: two loss years. A listed company losing money is not a fraud signal — it is a capacity-expansion signal — but it does mean the balance sheet, not the brochure, decides who gets priority when the plant is full.
Measured on 1 November 2026. The Chinese homepage returns 200 over HTTPS with 121,261 bytes — by far the largest page in this directory, because it carries the whole product taxonomy — declares lang="zh-cn", and contains zero blocks of structured data, zero language alternates and no canonical link.
The technical basics are better than most: robots.txt is 66 bytes of exactly the right thing — allow everything, declare the sitemap — and the sitemap returns 200 with 208 URLs. That combination is rarer in this directory than a green factory award. What is missing is the identity layer: nothing on the page states the USCC, nothing connects the Chinese brand to an English name, and there is no English page to connect it to. A crawler can read this site thoroughly and still not know which legal entity it belongs to.
The gap in one sentence. The plant publishes 208 pages a search engine can crawl, in one language, for a business that takes a fifth of its revenue from abroad and files its accounts in public.
Technical SEO hygiene and business legibility are different things. This is the one plant in the directory whose robots.txt and sitemap are both correct, and it fails the four checks that matter for a foreign buyer: no English page, no structured data, no legal identifier on the page, and a registered office in an office tower that does not appear on any factory gate. Buying from it is entirely possible — the accounts are public and the capacity is real — but nothing about the company's web presence will help you get there.
Four more delta plants are measured the same way, on the same day: in Huizhou, Victory Giant (胜宏科技, 300476) — ¥10.731bn revenue, registered as a chip maker — Glorysky (惠州市特创电子科技) — no HTTPS, registered as a repair shop — and Champion Asia (骏亚科技, 603386) — HTTP-only with three English names; and in Dongguan, Shengyi Electronics (生益电子, 688183) — ¥9.494bn revenue, majority-owned by China's largest laminate maker.
This is one of 16 measured plants in this directory. To compare it by question rather than by name — who publishes a layer count, who publishes a certificate number, whether the plant is too big for your order — use the buyer-question index. The rest of the region is measured together on the Pearl River Delta cluster page; the visit itself is covered by the factory audit checklist; the process view — who claims HDI, substrate, metal-core or flex — is the capability index.
