METHOD FOR MONITORING SOLDER OF FBGA-TYPE FPGA ONTO PCB

摘要

FPGA the present invention and PCB solder contacts a printed circuit board be equipped with multiple FPGA how inspection state and to a device that. ;Multiple FPGA data are installed on a printed circuit board compared with testing data together is selected by the other FPGA read and write data to determined in a single FPGA in the method for the printed circuit board of the solder contact and FBGA types according to the present invention and device that check FPGA, it reads, the accurate and easy FBGA types of FPGA solder contacts and printed circuit board, FPGA and printed circuit can determine the contact state of solder substrate.
