What this factory is. A small, capability-dense plant in Chuanshan District working the part of the market the bigger factories here avoid: small-batch and prototype runs of low-CTE ceramic substrate, high-thermal-conductivity copper-core, high-frequency microwave and rigid-flex boards, plus blind and buried vias. Registered in 2020, 53 insured staff, ¥40M registered capital (¥10M paid in), and a ¥100M special-PCB project launched in late 2022.
Why a buyer might want it. Nothing else in this directory does ceramic substrate. For radar, 77 GHz automotive, RF front-ends or thermal-critical boards, this is the supplier the cluster's big plants will subcontract to — and it takes small orders, which the 1,700-person plants will not.
The fault line, in one sentence. A company that talks about supporting national defence and radar equipment runs its website without HTTPS, and its robots.txt hands every crawler a sitemap URL belonging to a domain that no longer resolves.

This is the cheapest fix in the entire directory. Four faults, all of them configuration rather than content: buy a certificate, correct one line in robots.txt, point the marketing links at the real domain, done. The content — 158 pages, product descriptions, keywords, an about page that names radar and aerospace — is already written. Nobody told them.
Compare with the leaders. Yingchuangli has 240 Chinese pages and no English. Zhichao has a domain that only answers email. Haiying built an English site and never linked it to its Chinese one. Wanyexing has the most fixable problem of the four, and the least money to spend on it — which is exactly why the fix has to be sold on return, not on effort. A buyer's search for “low-CTE ceramic PCB, small batch, China” is a query this plant can already serve; it simply cannot be found by anyone who types it.
Open fields, not a rating. (1) Whether ceramic-substrate capability is in-house or brokered — ask for a process flow for an aluminium-nitride build. (2) Whether any defence-related work is actually performed, given that the company describes itself as civil-only in its own marketing. (3) ISO 9001 certificate number and the certification body. (4) What the ¥40M registered / ¥10M paid-in gap means for current capex plans. (5) Realistic lead time on a 4-layer high-frequency prototype versus the quoted 5–15 days. (6) MOQ — small-batch is the stated niche, so ask what “small” means in m².
