Meaning
Traceability in electronic component supply chains depends on identification labels placed on protective cartons that sit between the primary unit box and the master shipping container. These printed elements, called intermediate packaging marks, ensure that batch data remains visible during partial distribution of a product lot. They prevent identification losses when bulk shipments are divided into smaller quantities for regional warehouses.
Labeling Format
The barcode or matrix on the packaging contains the part number, batch number, and quantity. These intermediate packaging marks must conform to standard international supply chain formats to enable automatic scanning during logistics transitions.
Lot Traceability
Manufacturers use these labels to track parts from the silicon foundry to the sub-assembly plant. By scan-registering the intermediate packaging marks, the warehouse system maintains a continuous record of the storage conditions and transit times of the components. This systematic tracking is necessary for isolating defective batches during a product recall.
It ensures that only unaffected sub-assemblies remain in the supply stream. The presence of these marks allows the receiving warehouse to verify the authenticity of the components without opening each individual product pack, reducing the risk of environmental contamination.
Storage Instruction
Environmental sensitivity symbols are often printed alongside the barcodes. These intermediate packaging marks indicate the electrostatic discharge sensitivity, moisture sensitivity level, and correct orientation of the container. Observing these indicators protects delicate integrated circuits from environmental degradation before they are mounted to the circuit board.
