First Claim
Patent Images
1. A method of processing an unsingulated array of packaged semiconductor devices comprising the steps of:
- mounting the singulated array of packaged semiconductor devices on a mounting device;
then singulating the packaged semiconductor devices to physically separate the packages; and
then testing the singulated packaged semiconductor devices for defects while they are mounted on the mounting device and without removal therefrom.
