German project teams commissioning a test fixture should quote initial mechanical, electrical and test software development separately from additional stations, consumables, software licences, calibration and maintenance. A one-time development fee does not automatically include hardware for every later station or settle all operating costs.
Beijing Winge Technology Co., Ltd., operating as Winge, provides project-based electronic hardware and test fixture services. The following is a recommended budgeting and acceptance method; scope, prices, schedule and rights are agreed in the project documents.
Inputs needed before a quotation
Provide product and firmware versions, test points and wiring, known-good and faulty samples, test items, ranges, units and the basis for limits. Specify whether the complete station cycle includes loading, unloading, programming, waiting and data upload.
List initial and subsequent station quantities, existing instrument models and interfaces, mechanical space, power and safety conditions. Identify who supplies samples, reference equipment, software licences and on-site operation.
Six cost and responsibility records
Use this table to request quotations and assign responsibilities. Agree cost classification in the quotation; this is not a price list.
| Cost item | Initial work and deliverable basis | Recurring use and responsibility |
|---|---|---|
| Mechanical fixture | Positioning, probes and clamping design; list drawings and first-unit manufacture separately | Additional stations, wear parts and repairs; agree drawing rights and supplier |
| Electrical system and wiring | Interface circuits, harnesses and control design; design files and debug records | Hardware per station, spares and changes; assign procurement and replacement validation |
| Test software | Drivers, sequence, decisions and records; program, configuration and cases | Runtime licences, upgrades and new-product adaptation; agree source-code and maintenance scope |
| Reference equipment and instruments | Purchase or rental, integration and initial status checks | Availability, rental renewal and replacement; agree ownership and custody |
| Calibration and measurement validation | List measurement planning, reference comparisons and required external calibration separately | Recalibration, transport and downtime; agree interval basis and report scope |
| Operation and maintenance | Training, instructions, backups and fault-handling procedures | Consumables, upkeep and remote or on-site support; agree triggers and charging boundaries |
First-stage deliverables and acceptance
A first stage may cover an information review, test matrix, interface and responsibility records, cost breakdown and draft acceptance cases, delivering a gap list and next-stage scope. Assess missing information before committing to a total fixture price.
Agreed implementation deliverables should identify mechanical and electrical files, programs or configurations, a bill of materials, wiring, operating and maintenance instructions and version records. Separate reusable design from manufacturing, configuration and validation for each additional station.
Acceptance records should identify samples and fixtures, hardware, software and rule versions, instrument status, inputs, raw readings, units, limits and conclusions. Check good, faulty, timeout and interrupted cases; agree separate methods and pass criteria for measurement error, repeatability, cycle time and safety interlocks.
Calibration and handover for German projects
If a German project requires calibration reports from an accredited laboratory, first define the measurand, range, required uncertainty and intended report use, then check the laboratory's current accreditation scope. The DAkkS testing and calibration laboratory overview links to its laboratory directory. Confirm external calibration separately from fixture development.
Agree working language, drawing and record formats, sample transfers, remote integration and on-site responsibilities. Check currency, taxes, transport, compliance and downtime for the project; a country name does not establish a fixed recalibration interval, certification or fee.
Common questions
Does another fixture cost only the materials?
That cannot be assumed. Check design reuse rights, mechanical and electrical manufacture, instruments, licences, configuration and validation of each station. A new product or interface change also needs assessment.
Is calibration the same as acceptance of the complete fixture?
No. A calibration report covers only its stated object and conditions. The fixture also needs checks of contacts, sequence, decisions, records, fault handling and agreed safety and cycle-time requirements.
How are later changes split between maintenance and new development?
Record the cause, original agreement, change scope and retest cases. Distinguish defect handling, consumable replacement, rule changes and new-product adaptation, and agree responsibility and cost before implementation.
