BGA is the acronym of Ball Grid Array. In this kind of devices, the bottom of the package is composed by different pads with solder balls distributed in an array. It is a more or less a recent technology that appeared to increase the number of pads per size of package with respect older ones. It is very useful for digital circuits like FPGAs in which a high density of signals is required. It allows to concentrate more functions of the ICs using the minimum room in the PCB. It has some advantages and some disadvantages with respect other packages. [Read more...]
