Agree the Checks.
Keep the Records.
Quality requirements should be clear before production begins. We work with your team to define inspection, testing and the documentation needed for the build.
- Before production: review BOM revisions, assembly files, approved materials and acceptance criteria.
- During the build: apply the agreed assembly, programming and inspection steps.
- Before shipment: review test results and prepare the production and traceability records agreed for your project.
ISO 9001-certified quality management. RoHS-compliant materials. CE and FCC documentation support is assessed against the product and target-market requirements.

What files should I send for a PCBA quotation?
Please provide the BOM, Gerber or board files, assembly drawings or placement data, and expected quantities. Include firmware, test requirements and target delivery dates where available. If your data is incomplete, tell us what you have so we can identify the next information needed.
Can you support prototypes as well as volume production?
Yes. Vosnor supports prototype and NPI builds through to volume production. Minimum quantities, setup requirements and the production plan are reviewed against the board, materials and scope of work.
Can you source components or use parts we supply?
Both approaches can be reviewed. We can source to your approved BOM and vendor requirements, work with customer-supplied components, or agree a partial-sourcing arrangement. Proposed substitutions should be approved before procurement.
How are test coverage and delivery dates confirmed?
Test coverage depends on the board design, product functions, fixture requirements and agreed acceptance criteria. Delivery planning also depends on material availability, quantity and production preparation. Share your requirements so these can be reviewed before the build.
What does product assembly include?
The assembly scope is defined from your drawings, parts list and work instructions. Share the enclosure, connections, mechanical parts, test and packaging requirements so we can confirm the work to be included.
