Service
SMT Assembly
SMT assembly is the core of our in-house SMT PCB production line. Paste deposit, placement, reflow, and AOI inspection run as one continuous process, feeding optional firmware loading. Functional test, when the test plan calls for it, is coordinated through partner test houses.
What this service includes
- Solder paste stencil printing with dual squeegee
- Vision-assisted pick-and-place across 0201 to 35 mm components
- Multi-zone horizontal convection reflow, lead-free SAC305 capable
- Inline AOI on every assembled board
- Defect-rate logging per batch with feedback into DFM review
Production workflow for this service

-
Stencil and paste prep
Stencil mounted, paste loaded, alignment verified.
-
Paste deposit
Dual-squeegee print across the panel.
-
Component placement
Pick-and-place sequenced from the feeder bank.
-
Soldering and reflow
Profile selected from stored options, board passes through six zones.
-
AOI
Camera inspection of every joint and component.

Technical scope
- Placement accuracy
- +/- 0.025 mm
- Min component
- 0201
- Max component height
- 16 mm
- Max throughput
- up to 4800 cph theoretical, typical 2500 to 3600
Right fit when
- Your design uses SMT components and you need automated placement on a real production line.
- You need consistent reflow profile control across batches.
Frequently asked questions
Which design files do you accept?
Gerber RS-274X, ODB++, and IPC-2581 for PCB data. BOM in xlsx or csv with manufacturer part numbers. CPL or pick-and-place file in csv or txt. Step files for enclosures. Firmware binaries as hex, bin, or signed image bundles.
How is solder joint quality verified?
Automated optical inspection runs on every assembled board against IPC-A-610 acceptance criteria. We support Class 2 and Class 3 inspection profiles. X-ray inspection is available through partner labs for BGA and high-density boards when required.
What is your minimum order quantity?
No fixed minimum. We run NPI pilots from a single unit through recurring production into the tens of thousands per year. Single-shift line capacity is approximately 4.8 million component placements per year; programmes above that level we plan jointly across multiple shifts during DFM and BOM review.
