| Loom and Controller Compatibility | Compatibility with the loom model, jacquard head, control system, harness, connectors and communication protocol. | Confirmed compatibility with the exact machine configuration; all pin assignments, communication settings and firmware versions documented. | Approved compatibility list, wiring diagram, interface protocol, sample test report and written confirmation from the supplier’s engineering team. | 20% |
| Hook and Channel Capacity | Number of independently controlled hooks or channels supported by one board and the required expansion method. | Rated capacity should meet the machine requirement with at least 10% spare channels where practical. | Technical datasheet showing channel count, expansion architecture, wiring limits and a full-load demonstration. | 12% |
| Electrical Ratings | Input voltage, output voltage, peak current, continuous current, isolation and connector ratings. | All voltage and current ratings must match the loom power supply, with documented protection against overcurrent, short circuit and reverse polarity where applicable. | Electrical schematic, load test results, protection circuit description and safety test records. | 12% |
| Operating Speed and Timing | Maximum switching frequency, response time, timing accuracy and synchronization with the loom controller. | Supplier must provide tested performance at the customer’s required loom speed and pattern complexity; timing tolerance should be stated numerically. | Performance curve, oscilloscope or logic-analyzer test data, test conditions and synchronization specification. | 10% |
| Thermal and Environmental Reliability | Operating temperature, humidity, vibration, dust protection, cooling method and enclosure requirements. | Clearly declared operating and storage ranges; thermal testing at continuous rated load; protection level suitable for the installation environment. | Environmental specification, thermal imaging or temperature-rise report, vibration test information and installation requirements. | 10% |
| Quality Management | Manufacturing controls, incoming inspection, process inspection, final testing and traceability. | Documented quality system, preferably certified to ISO 9001:2015 or supported by equivalent audited procedures. | Valid certificate or audit report, inspection plan, serial-number traceability process and sample final-test record. | 10% |
| Regulatory Compliance | Material restrictions, electromagnetic compatibility and electrical safety requirements for the destination market. | Where applicable, documentation addressing RoHS Directive 2011/65/EU, REACH Regulation (EC) No 1907/2006 and relevant EMC requirements. | Declaration of conformity, material declaration, supplier declarations and applicable EMC or safety test reports. | 8% |
| Product Lifecycle and Maintainability | Component availability, firmware control, repairability, replacement procedure and backward compatibility. | Written lifecycle policy, controlled firmware releases and a replacement plan for discontinued components or board revisions. | Lifecycle statement, revision-control procedure, spare-parts list, repair instructions and change-notification policy. | 7% |
| Technical Support | Application engineering, troubleshooting, remote support, commissioning and documentation quality. | Named technical contact, complete installation documents and a defined response target for production-impacting issues. | Support procedure, escalation contacts, service-level terms, troubleshooting guide and commissioning checklist. | 5% |
| Delivery and Commercial Risk | Sample lead time, mass-production lead time, minimum order quantity, warranty and supply continuity. | Lead times stated in writing; warranty of at least 12 months is a practical minimum; payment, inspection and replacement terms clearly defined. | Formal quotation, production schedule, warranty terms, inspection agreement and business-continuity or capacity statement. | 6% |
