Baseline Split Ratios and Minimum Volume Floors in Dual Sourcing
Maintain a 70/30 production split with strict monthly minimum volume floors to preserve secondary line yields and protect against idle overhead surcharges.
Lot Code Traceability
Meaning
Quality tracking systems record the production history of individual components to ensure that any defects can be isolated to a specific manufacturing batch. This capability, known as lot code traceability, links each component on an assembled board to its original production lot and supplier.
Quality Tracking
Enterprise resource planning software monitors the movement of components from the incoming warehouse to the surface-mount technology line. When a reel of components is loaded onto a feeder, the operator scans the barcode to register the lot code traceability data for that specific production run. This scanning process associates the batch number with the serial numbers of the printed circuit boards produced during that shift.
This association allows the brand owner to verify the origin of every part in the final product.
Defect Mitigation
Product recalls are significantly narrower when a manufacturer maintains detailed record systems for all active and passive components. If a specific component batch is found to have a high failure rate, lot code traceability enables the quality team to identify the exact units that contain those parts. This precision prevents the need to recall entire production months, limiting the financial damage and preserving brand reputation.
The records also help identify if the issue originated from the component supplier or the assembly process.
Supply History
Regulatory documentation in fields such as medical electronics or aerospace demands strict verification of the component supply chain. Auditors regularly review the lot code traceability files to confirm that all parts come from authorized distributors and have not been mixed with unauthorized stock. This documentation forms a necessary part of the final quality pack delivered to the client upon completion of the order.
Without these records, the finished boards cannot be certified for use in critical applications.
