Prototype PCB Assembly
Prototype assembly turns a design release into physical boards for bring-up and evaluation. The priority is finding design and manufacturing issues early, while keeping revision control clear enough to learn from each build.
Release one consistent file set
Use a single revision for fabrication, BOM, placement and assembly drawings. Identify intentionally unpopulated components and any hand-fitted parts. If you expect component changes during bring-up, discuss access and rework before assembly starts.
Plan a first-article review
Agree which checks happen before the remaining boards are assembled. A first-article review may include polarity, orientation, critical placements and assembly notes. It does not replace the electrical checks that your design requires.
Keep bring-up separate from assembly acceptance
Define what the assembler will verify and what your engineering team will test. Power sequencing, firmware, programming fixtures and instrument requirements need a written plan. Record changes against a board serial number or batch reference.
What to include in your RFQ
- Versioned design release
- Quantity for bring-up, testing and spares
- Programming files and instructions if needed
- Critical component orientation notes
- First-article approval and test responsibilities
Confirm the process limits, material availability and acceptance criteria in your project quotation. They depend on the design and the manufacturing facility.
