SMT Assembly
Specifications

Our surface-mount lines run multi-head placement, fine-pitch BGA, and lead-free reflow soldering — engineered for 0201 components and ±25µm placement accuracy on every run.

0201 Capable ±25µm Accuracy Lead-Free Reflow Nitrogen Inert Atmosphere

Fine-Pitch Placement,
Built for High Yield

Our SMT lines combine multi-head pick-and-place, closed-loop solder paste inspection, and nitrogen-inert reflow to hold tight tolerances across 0201 passives and fine-pitch BGAs — without sacrificing throughput on high-mix production.

High-Speed Pick & Place

Multi-head placement machines rated for 0201 passives and fine-pitch components at production speed.

Fine-Pitch BGA Placement

0.4mm pitch BGA and QFN placement with vision-guided alignment for zero-defect solder joints.

Solder Paste Inspection

3D SPI on every board post-print, catching insufficient or excess paste before components are placed.

Lead-Free Reflow Soldering

SAC305 RoHS-compliant reflow with precision thermal profiling tuned per board stack-up.

Nitrogen-Inert Atmosphere

Nitrogen reflow reduces oxidation for cleaner, more reliable solder joints on dense boards.

In-Line AOI After Reflow

100% automated optical inspection scanning for tombstoning, bridging, and placement drift.

SMT Assembly — FAQs

What's the smallest component you can place?

+

Our lines are qualified for 0201 (0.6×0.3mm) passives and fine-pitch BGAs down to 0.4mm ball pitch.

Do you support nitrogen reflow for all jobs?

+

Yes, nitrogen-inert reflow is standard on our lines and is particularly recommended for dense, multi-layer boards or lead-free processes.

Can you handle mixed 0201 and larger through-hole components on one board?

+

Yes — we regularly run mixed-technology boards, sequencing SMT placement first followed by THT insertion and wave or selective soldering.

What inspection happens after SMT placement?

+

Every board passes through solder paste inspection pre-reflow and automated optical inspection post-reflow before moving to the next process step.
