| Placement & orientation | Component coordinates, board side, rotation, polarity, and assembly drawing review |
| Inspection | Component placement, polarity, solder-joint inspection, AOI, and X-ray to project requirements |
| Programming | Firmware loading and configuration according to supplied instructions |
| Functional testing | Board-level function checks, test fixtures, and acceptance criteria as agreed |
| Additional operations | Specified burn-in or aging, wiring, enclosure integration, and labeling |
| Production stages | Prototype builds, pilot batches, and repeat production |
Component dimensions, package pitch, board size, and production schedule are reviewed against the supplied design and assembly files.
Closed-loop quality control
Four Checkpoints.
One Consistent Build Standard.
Follow each assembly from incoming materials through process checks, final verification, and shipment review.
IQC
Incoming Material Control
Check board condition, component identification, BOM revision, and supplied-material quantities before the build.
IPQC & FAI
In-Process & First-Article Review
Review placement, orientation, and soldering on the initial assembly. Align production checks with the approved build documentation.
FQC
Finished Assembly Verification
Complete visual and solder-joint checks, then programming and functional tests according to the agreed acceptance criteria.
OQC
Outgoing Quality Review
Check assembly identification, required inspection records, protective packaging, and shipment quantities before dispatch.
Inspection & verification
Inspect the Joints.
Test the Functions.
- AOI for placement, polarity, and visible solder features
- X-ray for hidden-joint inspection where specified
- Firmware loading and board-level functional tests
- Agreed burn-in, aging, and final appearance checks
PCB assembly process
See How Your Assembly Moves Through Production
Explore the principal stages of an SMT build, with through-hole and test operations coordinated to your project.
Prepare the Surface-Mount Build
- Confirm the stencil and assembly revision
- Apply solder paste to the required pads
- Review print alignment before component placement
Place Components to the Approved Data
- Use BOM and placement data from the same revision
- Check orientation, polarity, and component identity
- Review fine-pitch and BGA assembly requirements
Form and Inspect the Solder Joints
- Coordinate reflow and through-hole operations
- Inspect visible joints and component positions
- Resolve assembly findings against the agreed criteria
Verify the Defined Board Functions

PCB assembly FAQ
Plan Your Build with Confidence
Can you source all the components for my PCB assembly?
Yes. Choose turnkey assembly for coordinated PCB fabrication and component sourcing, or partial-turnkey if you want to supply selected parts. Include manufacturer part numbers and your sourcing preferences in the BOM.
Can I supply my own boards or components?
Yes. Consigned and partial-turnkey arrangements are available. Share the supplied-material list, available quantities, and any packaging or handling requirements before shipment.
Do you assemble BGA and fine-pitch components?
Yes. Include the package details, board files, and inspection requirements so we can review the assembly scope and required checks.
What is needed for functional testing?
Provide the test procedure, expected results, firmware, and any required fixtures or interfaces. We agree the test coverage and acceptance criteria before the build.
What happens if a component is unavailable?
We review procurement availability and coordinate proposed alternatives with your team. Substitutions are agreed before they are used in the assembly.
Can you also supply an enclosure and final assembly?
Yes. We can coordinate PCB assembly with enclosure manufacturing, wiring, final product assembly, programming, and testing.
How is assembly lead time determined?
The schedule depends on board fabrication, component availability, assembly complexity, quantity, and testing. The quotation confirms the production plan for your project.
