From bare board loading to finished PCBA unloading — Keli Automation designs and integrates complete surface mount technology production lines. Whether you need a compact entry-level line or a high-speed fully automated system, we deliver turnkey solutions optimized for your product mix and volume requirements.
A complete 9-station workflow engineered for seamless synchronization, maximum throughput, and zero-defect manufacturing.
Each station in the SMT line is carefully selected and integrated to deliver consistent quality and reliable throughput.
Magazine-style board loader that automatically feeds bare PCBs from stacks into the production line. Supports standard PCB sizes up to 330×250mm, with SMEMA communication for seamless line integration. Adjustable width for quick product changeover.
Fully automatic stencil printer with vision alignment for precise solder paste deposition. Features automatic stencil cleaning, 2D inspection, and squeegee pressure control. Supports fine-pitch printing down to 01005 components and 0.3mm pitch QFNs.
3D solder paste inspection system that measures paste volume, height, area, and offset with micron-level accuracy. 100% inspection of all pads before placement, catching printing defects early when rework cost is lowest. Full SPC data output for process control.
High-speed chip shooter + precision placer configuration for optimal CPH (components per hour) and component range. Handles 01005 chips through large connectors and BGAs. Modular feeder setup with automatic tape splicing for uninterrupted production runs.
Multi-zone forced convection reflow oven with precise temperature profiling. Nitrogen-capable for advanced soldering processes. Supports lead-free and leaded solder profiles. KIC-style thermal profiling and closed-loop zone temperature control for consistent results.
Post-reflow AOI system with high-resolution cameras and AI-assisted defect detection. Identifies solder bridges, tombstones, missing components, polarity errors, and insufficient solder. Supports both 2D and 3D inspection technologies for comprehensive quality coverage.
CNC routing or laser depaneling for stress-free PCB separation from multi-up panels. Supports V-cut, tab-route, and mixed panelization methods. Integrated dust extraction and vision alignment for precision cutting. Essential for minimizing board stress on sensitive components.
In-circuit test and functional test stations verify both component-level and board-level performance. Custom test fixtures ensure reliable contact with test points. Test data feeds directly into MES for full traceability and pass/fail sorting.
Finished board unloader stacks good PCBs into magazines for downstream processing. Integrates pass/fail sorting based on test results, routing defective boards to rework stations. Optional robotic unloading for direct tray or conveyor handoff.
A specialized 7-station post-reflow line that automates everything after the reflow oven — maximizing throughput while minimizing manual handling and ESD risk.
Ergonomic loading station with anti-static protection and barcode scanning for production traceability from the start of the post-reflow process.
Bed-of-nails in-circuit testing verifies component placement, solder joints, and electrical continuity with automatic fault diagnosis.
Functional circuit testing validates operational behavior under real-world conditions including power-on self-test and signal verification.
Precision XYZ gantry dispensing system for component securing, conformal coating, and thermal adhesive application with programmable patterns.
Automatic board inversion for dual-side processing with laser or inkjet marking for serial numbers, date codes, and traceability labels.
Dual-spindle CNC routing system for stress-free PCB panel separation. Supports V-cut, tab-route, and mixed panel formats with dust extraction.
Robotic arm picks finished PCBAs and places them into trays or onto downstream conveyors, with pass/fail sorting based on test results.
