Abstract

The present disclosure provides a welding-pad repair device and a welding-pad repair method. The device includes: a de-soldering component, an insulating layer removal component and a cleaning component; a welding-pad coating mechanism for forming an initial welding pad, where the welding-pad coating mechanism includes a coating component and a curing component; and a welding-pad encapsulation mechanism for performing an encapsulation operation on a welding pad and a circuit exposed at a periphery of the initial welding pad to form a new welding pad having a predetermined exposure pattern. Embodiments of the present disclosure provide a welding-pad repair device and a welding-pad repair method capable of effectively repairing defective pads before and after dies are bonded, thereby solving problems of low product yield and high cost caused by defective welding pads.
