with JEDEC standards JESD51-2 and JESD51-6, and the junc-
tion-to-board measurement complies with JESD51-8. Test
board and thermal via design comply with JEDEC standards
JESD51-9 (BGA). The junction-to-case measurement complies
with MIL-STD-883 (Method 1012.1). All measurements use a
2S2P JEDEC test board.
Industrial applications using the 208-ball BGA package require
thermal vias, to an embedded ground plane, in the PCB. Refer to
JEDEC standard JESD51-9 for printed circuit board thermal
ball land and thermal via design information.
