Abstract:
1. A method for determining locations of maximum deflection of a printed circuit board (PCB) under test, said PCB to be mounted in a tester fixture of a printed circuit board tester, said method comprising: obtaining boundary conditions of said PCB; obtaining loading conditions of said PCB; obtaining first vertical force magnitudes at associated first vertical force locations to be applied to said PCB by said tester fixture in a first direction and/or obtaining second vertical force magnitudes at associated second vertical force locations to be applied to said PCB by said tester fixture in a second direction; determining a location of maximum deflection of said PCB conditioned by said boundary conditions of said PCB, said loading conditions of said PCB, said first vertical force magnitudes at said associated first vertical force locations to be applied to said PCB by said tester fixture in said first direction, and said second vertical force magnitudes at said associated second vertical force locations to be applied to said PCB by said tester fixture in said second direction.
