200K CPH/Line

Placement Speed

High-speed modular SMT lines with dual-lane capability. Up to 200,000 components per hour per line. Automatic changeover reduces downtime between batches. Suitable for both high-mix low-volume and mass production runs.

1,200×510

Max Board Size (mm)

Standard PCB size up to 510×460mm. Extended rail up to 1,200×510mm for LED strips and backplanes. Board thickness 0.3mm–6.0mm. Panel up to 600×800mm with fixture support for over-sized assemblies.

Soldering Technologies

SMT reflow — 10-zone oven, N₂ atmosphere, ±1.5°C profile control. Wave soldering — dual-wave for mixed-technology boards. Selective soldering — nozzle-based for through-hole on double-sided SMT. Lead-free (SAC305) or leaded (Sn63Pb37).

IPC Class 3

Workmanship Standard

IPC-A-610 Class 2 as standard for commercial/industrial products. Class 3 for aerospace, medical, and automotive. IPC J-STD-001 for soldering process. ANSI/ESD S20.20 ESD control.

Free

DFM & BOM Validation

Every order includes a free assembly DFM review. We validate footprint-to-package match, paste stencil aperture, polarity/orientation, component spacing, and BOM part number cross-reference before production start.

Assembly Process Flow

Solder Paste Printing

Laser-cut stencil (0.08–0.2mm). Automatic paste inspection (SPI). 100% area coverage check per pad.

Pick & Place

High-speed & fine-pitch placement. Vision alignment. Real-time component verification. Feeder and reel traceability.

Reflow Soldering

10-zone profile. N₂ atmosphere. ±1.5°C per zone. Ramp-soak-spike to J-STD-020. Post-reflow cooling control.

AOI Inspection

3D AOI on every board after reflow. Solder joint quality, bridging, tombstoning, lifted leads. Automatic pass/fail.

Test & Conformal Coating

ICT, FCT, flying probe. X-Ray for BGA/QFN. Conformal coating. Final QA before packaging.

Inspection & Testing

SPI

Solder Paste Inspection on every print. 3D volumetric measurement. 100% pad coverage. Catch stencil issues before placement — no rework downstream.

3D AOI

Automatic Optical Inspection on every board after reflow. 3D solder joint profiling. Bridging, tombstoning, lifted leads, missing components. Automatic pass/fail with human review on borderline cases.

X-Ray

2D/3D X-Ray for BGA, QFN, and hidden joints. Void detection, solder ball integrity, bridging under packages. Mandatory for Class 3 assemblies. Programmable inspection paths per board design.

ICT

In-Circuit Test — bed-of-nails fixture per design. Component value verification, open/short detection, polarity check. Fixture design and fabrication in-house. Flying probe available for low-volume / prototype.

FCT

Functional Circuit Test — powered-on board exercising real operating conditions. Custom test jig per product. Firmware flashing, calibration, and burn-in available. Full test report with every shipment.

Micro-Section

Conformal Coating & Protection

Acrylic (AR)

General-purpose. Good moisture & fungus resistance. Easy rework. Widely used in consumer, industrial, and IoT products.

Silicone (SR)

Wide temperature range (-65 to +200°C). Excellent for automotive under-hood and aerospace high-temp environments.

Polyurethane (UR)

Excellent chemical & abrasion resistance. Fuel and solvent resistant. Common in industrial and harsh environments.

Parylene (XY)

Vapor-deposited nano-coating. Ultrathin (0.1–25µm), pinhole-free. The gold standard for medical implants and mil/aero electronics.
