What this factory is. A 74-person board shop on Mingxing Avenue running the products the big plants in this cluster treat as filler work: automotive lighting and lamp-bar boards, 6-layer 3 oz heavy-copper power and ceramic boards, FPC harnesses, and up to 10-layer security decoder boards. Registered in 2017, ¥30M registered capital with ¥10.9M paid in, High-Tech Enterprise and provincial Specialised & Sophisticated SME, with customs registration for export.
Why a buyer might want it. Lighting boards and FPC harnesses are where this cluster is thin. Most of the plants here quote computer, communications and display boards; this one quotes car-lamp metal-core, 6-layer 3 oz power, ceramic and flexible harness work — and its own 2022 press describes an automated line running at 80%, which is the kind of claim a visitor can check in ten minutes.
The fault line, in one sentence. Its live website has never had its content-management placeholders replaced: the meta description reads “网站描述” (website description) and the keywords field reads “网站关键字” (website keywords) — so every search engine and every AI crawler reading that page is told, in the site's own words, that the description is a description.

This is not neglect. It is a finished job that was never started. Somebody paid for a site, chose a template, filled in the products — and nobody ever opened the SEO settings panel. The description field still holds the label the CMS put there. Compared with the other profiles here, the fix is trivial and the upside is immediate: write two sentences and one comma-separated keyword list, delete one test SKU, buy a certificate, publish a sitemap. A morning's work.
The deeper problem is that capability is not being described at all. Automotive lighting boards need thermal cycling data, CTI, and an IATF certificate. The site says “operates ISO/TS 16949”, a standard retired in 2016. An engineer sourcing a car-lamp board in 2026 reads that and stops. The plant may well hold IATF 16949 — it is a Specialised & Sophisticated SME with 74 staff and 80% automation — but nothing on the page proves it, and the page is the only thing a distant buyer sees.
Compare with the leaders. Yingchuangli has 240 Chinese pages and 146 English ones, on a site whose English homepage names a fingerprint-lock company. Zhichao has a domain that answers only email. Guangtian has a full English site and is in judicial auction. Kaishengshi has a technically adequate site whose metadata is a placeholder — the gap between what this factory can build and what it says it can build is the widest in the directory, and it is measurable in one HTTP request.
Open fields, not a rating. (1) IATF 16949 certificate number and certification body. This is the single most important field for automotive lighting work, and the site cites a withdrawn standard instead. (2) Whether the metal-core and ceramic capability is in-house — ask for the thermal-conductivity grade and the dielectric used. (3) The actual layer stack behind the “10-layer security decoder board” — 10 layers at what trace/space and what via structure. (4) Which plant is producing: the registered address names another company's building, and that company has filed as suspended. Ask for the lease or ownership document and the exact production floor. (5) Current headcount and payroll period — 74 insured is the 2025 filing, not today. (6) Whether the ¥30M registered capital has moved past ¥10.9M paid in, and what that means for equipment. (7) UL mark, if any — not mentioned anywhere.
