Russian project teams commissioning a PCB (printed circuit board) revision should separate design changes, prototype manufacturing and debugging costs. Equal board quantities do not imply equal effort: existing project completeness, changes and test conditions define the quotation scope.
Beijing Winge Technology Co., Ltd., known as Winge, provides electronic hardware and prototype development services. The following is a suggested quotation method; work, delivery rights and commercial terms are agreed per project.
Inputs needed before a quote
Provide schematics, editable PCB projects, tool and library versions, the bill of materials (BOM), manufacturing outputs, and existing boards and firmware versions. List known faults and reproduction steps.
Mark each requirement as retained, changed or new, with interface, power, mechanical and operating environment constraints. List missing files before assuming the old design can be reused.
Six cost drivers and record fields
Use this table to define quotation inputs and scope; it is not a public price list.
| Record | Inputs to confirm | Basis for separating costs |
|---|---|---|
| Existing project | Sources, libraries, versions and usage rights | List assessment, recovery or reconstruction separately |
| Design changes | Change list, affected interfaces and mechanics | Schematic, layout, routing and regression scope |
| Bare boards | Dimensions, stack-up, material, process and quantity | Calculate against an agreed manufacturing batch |
| Parts and assembly | Part numbers, packages, quantities and substitution approval | Separate procurement, assembly and transport; avoid double charging |
| Bring-up and debugging | Board IDs, firmware, instruments, tests and thresholds | Agree functional checks, diagnosis and retesting |
| Further revision | Issue records, reasons for changes and approver | Distinguish agreed defect handling from new requirements |
Assess first, then agree delivery and acceptance
An initial work package can cover opening projects, comparing versions and reviewing changes, delivering a missing-input list, risks and subsequent work packages. Estimate price and schedule from that scope.
Agreed design deliverables include editable projects, change records, manufacturing files and check reports tied to one revision. A clean design-rule check does not replace physical functional acceptance.
Record board ID, firmware, wiring, instruments, inputs, thresholds, actual results and unresolved issues for prototype acceptance. Video can supplement records but cannot alone prove all tests passed.
Remote coordination for Russian projects
For remote work, agree drawing and review-document languages, meeting time zones, board transfers, and each party's test equipment and operating responsibilities. Scope Russian-language documentation separately.
Confirm currency, quote validity, payment, taxes, transport and certification work separately; the country name does not determine fixed charges or applicable requirements.
Questions and answers
Is board quantity enough for an actionable quote?
No. Project completeness, changes, manufacturing specifications, parts and test scope are also needed. An assessment package can address missing inputs first.
Can a board be revised directly from Gerber files alone?
That cannot be assumed. Gerber files are manufacturing outputs; check editable projects, libraries and usage rights, and define reconstruction separately.
How is a second revision charged?
Record the issue, cause, changes and retest scope. Distinguish agreed defect handling, new requirements and external manufacturing costs before approving the change.
