Aaltosemi

AaltoSemi (Chinese name 芯爱科技（南京）有限公司) is an integrated-circuit packaging substrate manufacturer founded on 8 May 2021 and headquartered in the Pukou Economic Development Zone in Nanjing, Jiangsu, China. The company designs and fabricates the organic substrates that carry the electrical connection between a semiconductor die and the printed circuit board, covering both BT and ABF material systems across Coreless, ETS, FCCSP, FCBGA (BT) and FCBGA (ABF) product families for consumer electronics, high-performance computing, communications, automotive and medical applications, and it offers those as an end-to-end service spanning R&D, design, production and test. Its Nanjing fab is a high-automation plant with a stated annual capacity of roughly 1.45 million substrate panels, and the company holds IATF 16949 and VDA 6.3 quality certifications and has filed more than twenty patents since founding. The name is taken from the Finnish designer Alvar Aalto. AaltoSemi is a hardware manufacturer: it sells physical substrates to chip makers and OSATs, and it publishes no public API, developer portal, SDK or machine-readable contract of any kind.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/aaltosemi: open an issue to ask a question, or submit a pull request to add artifacts.
