Summary:
The resonances of the electromagnetic field in the space between a BGA and a PCB has been analysed. The equations that give quality factors at resonant frequencies about Model A and Model B have been derived theoretically. In Model A, the space between the BGA and the PCB is shut by setting a lot of shield posts connecting the edges of the BGA to the PCB. Model B is without the shield posts. The equations have been examined in electromagnetic simulation.
