Defect Classification - ADC

ADC is essential for facilitating efficient repair processes

Orbotech's cutting-edge, Automatic Defect Classification (ADC) is used in the global FPD industry by many panel manufacturers. Automatic Defect Classification is implemented for monitoring the production process, for Go/No-Go decisions and repair judgment. As repair techniques continue to be improved, ADC is essential for facilitating efficient repair processes.

In a price sensitive and competitive market where material costs are high and account for total cost of large panel displays – FPD manufacturers must maintain the highest possible yields. Orbotech's AOI systems, featuring ADC capabilities, maintain those yields while improving product quality and productivity in a highly competitive marketplace.
