Method for repairing an electronic substrate and method for making an led display

Abstract

A method for repairing an electronic substrate by removing a bad electronic component from a pad on the electronic substrate uses steps of: providing a control pad image; providing an image of the pad with which the bad electronic component is bonded; comparing the image of the pad with which the bad electronic component is bonded with the control pad image to determine a difference between the said images; generating a positioning directive based on the difference, and following the positioning directive to position the bad electronic component; and applying an energy beam onto the positioned bad electronic component to deconstruct a bonding between the positioned bad electronic component and the pad. A method for making an LED display is also provided.
