A machine vision-based IC chip positioning marking and character recognition detection scheme
IC chips are an integrated circuit formed by a large number of microelectronic components (transistors, resistors, capacitors, etc.) placed on a plastic substrate to make chips. Chip appearance identification and testing is an indispensable and important link, which directly affects the quality of IC products and the smooth progress of subsequent production links. Machine vision inspection is characterized by high efficiency, accuracy, automation, and low cost, which helps to improve product quality, production efficiency and yield. It is widely used in the electronics industry and is a development trend in IC chip inspection.
