Title: Testing device of mini ball grid array base
Inventor: LI BING-HUAN
IPC: H01L21/66
Filed: 1999-02-01
Granted: 2000-07-01
Abstract: A testing device of mini ball grid array is provided, which has a machine platform sequentially arranged with a wafer feeder, a die sorter and transfer module, and a transmission module, that are operated with a host control system. With automatically feeding the sliced mBGA wafer into the die sorter and transfer module, the condition of the solder ball on the mBGA IC substrate is automatically inspected by the digital image processing device of the die sorter and transfer module. The inspected mBGA Ics are automatically transferred to the carrier on the transmission module one by one. The transmission module can move out the carrier automatically to operators for taking off the Ics and receive empty carrier. Therefore, the accuracy of the inspection process to the mBGA IC is increased and the process can be automatically performed.
