A Shenzhen service profile, not one magic capability number.
The named company, 深圳市品升高精密电路有限公司, describes a service path from circuit design and PCB layout through fabrication, SMT, mechanical assembly and functional testing. Its PCB and SMT pages publish different technical tables. They should be compared as separate scopes when reviewing a mixed PCB/PCBA quote.
The website says it operates a production workshop and offers inspection equipment; this page does not convert those descriptions or the site's certificate imagery into independently verified certifications, equipment ownership or a specific UL file.
Ask for one feasible construction.
The manufacturer's PCB table spans 1–40 layers, 2/2 mil minimum line/space, 0.5–12 oz copper and 0.2–7 mm board thickness. These are separate rows; the site does not show that the extremes coexist on one board. The same table labels 0.15 mm as a minimum hole without identifying it as finished size.
If your job requires fine routing and heavy copper together, request a stack-up-specific DFM answer. The published 0.2 mm minimum thickness applies to the two-layer row; the minimum thickness rises with layer count in the same table.

The file package changes at assembly.
Confirm the bare-board build
Pinsheng lists Gerber, DXF, PCBdoc and ODB++ among its accepted fabrication formats. Include the layer stack, finished dimensions, copper and surface finish, and identify any impedance or drilled-versus-finished-hole requirement.
Provide the assembly definition
Its SMT page separately asks for a BOM, placement/coordinate file, assembly drawing and a functional-test guide. Decide whether components are customer-supplied or procured, and who owns substitutions, programming and fixtures.
The quote should name the handoff
Match the two acceptance records
The assembly page describes SPI/AOI and X-ray inspection as well as ICT and functional-test options. Ask which checks are included for your assembly, what evidence will be returned, and who handles a failed board or a component change. Do not assume every stated inspection is applied to every order.
Four original pages, separate scopes
