Study of puncher materials for singulation process in semiconductor manufacturing industry / Vikram Nanthanar
Punching or Singulation is one of the most common processes used in many semiconductor industries as a separation process from a substrate which contain four to nine units. Having a basics understanding of the material to be used in the punching process can help to improve the tool life thus can inc...
