Figure 6.3 A6G2C core board dimensions
Note: In Figure 6.3, the tolerance of hole diameter dimensions is +/-0.1 mm, and the tolerance of the external
dimensions of the board is +/-0.15 mm.
Pay attention when choosing the fixing column of the four positioning holes of the core board. You must
choose a fixed column with a height that is exactly the height between the base plate and the core plate. If the
fixed column is too high, it will lead to poor contact of the core board; if the fixing column is too low, the core
board will be deformed after the screws are tightened, which will cause poor contact and affect the use. It is
recommended to use copper pillars of Ф 2 x 3 + 3.5 mm
Due to the large number of BGA components on the core board, it is recommended not to remove and
insert the board frequently. When you need to remove and insert the board, you must be careful to avoid PCB
deformation; otherwise, the component may be falsely welded.
