About
Zhixin Heng is a PCB solution design company. One team, from schematic through production release.
Who we are
Zhixin Heng does PCB solution design. Concretely: you have a product idea or a schematic, and we turn it into a board that can be built repeatably — schematic cleanup, stackup planning, PCB layout, DFM review, signal-integrity simulation, and the full release of Gerber, assembly documentation and source files.
We do not broker components, and we do not earn design fees from parts margin. The design fee is the design fee, with no purchasing rebate folded in — which means our component and alternate recommendations are made from the board's point of view.
The company was founded in Shenzhen in 2018. The team is electronic engineering background, working with hardware R&D teams both in China and overseas.
What solution design means here
PCB solution design is not just routing a board. It is translating function, performance, cost, process and production risk into a board that can actually be built, repeatedly and reliably.
TEAM
01 — RolesWho is on a project
These are the roles we actually staff on a project. Who is on yours depends on how complex it is.
R-02
Schematic Engineer
原理图工程师
Module breakdown, ERC, symbol and footprint libraries, BOM maintenance.
R-03
Layout Engineer
Layout 工程师
Stackup planning, placement and routing, impedance and matching, HDI and flex.
R-04
Process & DFM Engineer
工艺与 DFM 工程师
Works against the fab's real capability, sets DRC and DFM rules, checks panelisation and assembly.
R-05
Simulation Engineer
仿真工程师
SI / PI, thermal analysis and EMC pre-assessment, brought in as the project requires.
R-06
Production Liaison
生产对接
Prototype tracking, assembler communication, revision closure, production release sign-off.
R-07
Supply Chain
供应链
Component alternates, availability, kitting and BOM sourcing support.
R-08
Programme Management
项目管理
Schedule, versions, change records and release archiving.
QUALITY & CONFIDENTIALITY
02 — QualityQuality and confidentiality
Both matter more than they look. The first decides whether the board ships; the second decides whether you can hand us your files at all.
✓Standards firstDesign rules come from IPC standards and the fab's process capability together — not a copied default sheet.
✓DFM on every boardA manufacturability pass before release, so problems surface before the prototype.
✓Stackup and impedance confirmedStackup must match the fab's real stackup before we call impedance done.
✓Traced changesEvery revision is recorded, and source files always match the released version.
✓ConfidentialNDA signed. Project material is not shared, reused, or shown as a case study.
✓Sources are yoursDesign work and source files transfer with the release, with no ongoing restriction.
✓Released to the fab's formatDrill format, panelisation rules and impedance test requirements are followed as specified.
✓We do not promise what we cannot doThe assessment says plainly what is out of scope, rather than explaining it later.
