Abstract
Description
technical field
[0001] The invention relates to a method for reworking and rescuing integrated circuit components, in particular to a method for selecting whether to re-solder soldered integrated circuit components packaged in a ball grid array, so as to save the integrated circuit components for the next step of testing. Methods of operation of circuit assemblies. Background technique
[0002] Generally speaking, when the customer finds substandard integrated circuit components, they will return these integrated circuit components to the manufacturer, hoping to conduct quality analysis or replace them. At this time, the manufacturer will try to determine whether these returned IC components are really unqualified IC components as the customer said, and if they are really unqualified IC components, they can understand which pins are faulty and why. The unqualified analysis will help IC component manufacturers to refer to the next batch of IC components to avoid the occurren...
