Financial Assessment
The total expense of sourcing, manufacturing and delivering a printed circuit board assembly to its final destination represents the true economic baseline for supplier selection. This metric, known as landed cost calculation, incorporates the base unit price, shipping fees, customs duties and transit insurance. It ensures that procurement teams do not rely solely on the ex-works factory price when evaluating foreign electronic manufacturing services.
A detailed formula avoids unexpected budget overruns. The calculation must also account for any localized testing or packaging requirements performed after arrival.
Logistics Factor
Freight charges and tariff rates vary based on the shipping method and origin country. Air freight delivers assemblies quickly but adds high costs, whereas ocean transport reduces the cost per unit but extends the holding time of the inventory. These logistics variables are modeled alongside assembly costs to determine the most cost-effective supply chain path.
This analysis prevents expensive delays.
Procurement Impact
Quality issues and rework costs at the receiving point can alter the final cost of a production lot. A cheap supplier with higher defect rates often yields a higher total cost than a premium manufacturer with zero-defect runs. This reality forces purchasing departments to factor in risk and quality yield metrics.
The resulting total cost model guides strategic sourcing decisions.
