"I am trying to locate information relating to the actual usage of Plastic
Ball Grid Arry (PBGA) devices. I am interested in info relating to the
mounting, temperature cycling, problems, and long term field performance of
this type of device.
Am also searching for data that illustrates whether plastic microcircuit
packages will support the growth of a fungus, or not. Should I be
concerned, or not, and why....?????

My reply: A good technical source for information would be:
Plastic Ball Grid Array (PBGA), Document # AN1231/D published by Motorola.
Motorola may have some additional reliability data they could share.
