| Placement Speed | Approximately 10,000–30,000 components per hour for compact or medium-scale SMT production. | Higher theoretical speed can improve output, but practical performance depends on feeder changes, board complexity, and component mix. | Request a placement test using the customer’s actual PCB files, component list, and production program. |
| Placement Accuracy | Typically around ±0.03–0.05 mm under documented operating conditions. | Accurate placement helps reduce solder defects, rework, component waste, and alignment problems. | Check repeatability data, calibration procedures, sample boards, and inspection results from a controlled trial. |
| Component Range | Support for common chip packages, small passive components, integrated circuits, connectors, and selected odd-form parts. | A wider component range allows one machine to serve more products and reduces equipment changes. | Compare the machine’s feeder, nozzle, camera, and component-size specifications with the actual bill of materials. |
| PCB Compatibility | Adjustable support for the required PCB length, width, thickness, weight, and panel configuration. | Correct board handling prevents vibration, transport errors, registration problems, and production interruptions. | Confirm the permitted PCB dimensions and test single boards, panels, thin boards, and heavy boards when applicable. |
| Vision and Alignment | Upward and downward vision functions, fiducial recognition, component verification, and automatic correction. | Reliable vision improves placement quality when boards, components, or solder pads have small positional variations. | Test fiducials, polarity marks, fine-pitch packages, reflective parts, and components with different surface finishes. |
| Feeder System | Stable tape, tray, stick, and bulk-feeding options where required, with quick setup and clear feeder status monitoring. | Feeder reliability directly affects changeover time, placement continuity, and material loss. | Evaluate feeder repeatability, spare-part availability, loading time, and compatibility with the planned component packaging. |
| Software and Programming | Intuitive programming, CAD and BOM import, offline preparation, barcode functions, and production-data storage. | Efficient software reduces setup errors and makes product changeovers faster and more consistent. | Ask for a live programming demonstration using real customer files rather than a prepared sample project. |
| Changeover Efficiency | Fast product changeover supported by feeder carts, setup verification, recipe management, and clear operator instructions. | Shorter changeovers are especially valuable for high-mix, low-volume manufacturing. | Measure the complete changeover process, including feeder replacement, program selection, verification, and first-board approval. |
| Machine Availability | Designed for stable continuous operation with effective alarm handling and accessible maintenance points. | Availability often has a greater effect on output than maximum advertised speed. | Request documented uptime records, failure-response procedures, preventive-maintenance schedules, and service commitments. |
| Maintenance and Spare Parts | Clear maintenance procedures, commonly available wear parts, technical documentation, and responsive remote support. | Accessible support lowers downtime and helps operators resolve routine problems safely. | Review the spare-parts list, service response time, training plan, warranty coverage, and escalation process. |
| Inspection and Traceability | Compatibility with barcode scanning, production records, placement verification, and integration with inspection equipment. | Traceability supports quality control, process analysis, and faster root-cause investigation. | Confirm supported data formats, communication interfaces, barcode standards, and data-export functions. |
| Safety and Compliance | Emergency stops, guarded moving parts, safety interlocks, electrical protection, and documentation for the destination market. | Safety features protect operators and support smoother installation and customer acceptance. | Verify the applicable electrical, machinery-safety, and electromagnetic-compatibility documentation for the intended country. |
| Total Cost of Ownership | Evaluate purchase price together with installation, training, feeders, nozzles, software, maintenance, energy use, and downtime risk. | The lowest initial price does not always provide the lowest cost per correctly placed component. | Prepare a multi-year cost model based on actual production volume, staffing, maintenance intervals, and expected utilization. |
