Solid State Interdiffusion Microvoid Formation Kinetics in Electronic Packaging
Kirkendall microvoid formation in solder joints is driven by asymmetrical copper diffusion across Cu3Sn layers and accelerated by substrate plating organic inclusions.
Landed Scrap Cost
Meaning
Total financial outlays for non-conforming material include the original purchase price and all transport expenses incurred before the waste reaches a disposal site. Calculating the landed scrap cost involves adding the initial procurement price to the freight, insurance, handling fees, and import duties paid upon entry into the territory. This figure represents the true loss to the manufacturer when a raw material is rejected before it enters the production line.
Companies use this value to negotiate claims against international suppliers or logistics providers.
Valuation Component
The calculation includes every expenditure required to bring the material to the factory gate. A landed scrap cost covers more than just the invoice price because it accounts for the wasted logistics capacity. In China, where customs duties can be high for specific raw materials, the duty portion of the cost is often non-recoverable.
This makes the total loss significantly higher than the book value of the material itself.
Waste Recovery
Financial recovery from defective items depends on the ability to prove the condition of the goods at the point of transfer. The landed scrap cost provides the baseline for insurance claims and supplier credits. If the scrap is sold locally for recycling, the revenue is subtracted from the total cost to determine the net loss.
Documentation of the disposal process is mandatory for maintaining the integrity of the inventory records.
Expense Recognition
Accounting departments must write down the value of the inventory once the material is identified as scrap. The landed scrap cost is moved from the balance sheet to the income statement as a cost of goods sold or a separate loss account. Frequent occurrences of high scrap costs suggest problems in the procurement or quality control process.
Management monitors these figures to improve the efficiency of the supply chain.
