ROI Calculation Logic

Assuming a current plating-related defect rate of 5% in electronic component manufacturing, this technology could reduce the defect rate to 1%. With a monthly production of 100,000 units, a unit price of $20 (AI est.), and defect costs (materials, processing, inspection) at 50% of the unit price, monthly defect reduction is (100,000 units × 4%) = 4,000 units. The cost reduction is (4,000 units × $20 (AI est.) × 50%) = $40,000/month (AI est.). Annually, this projects to $480,000 (AI est.) in cost savings. Additionally, extended product lifespan and enhanced brand value are expected due to increased reliability.
