Ian:
Regarding your JEDEC inquiry, JEDEC has issued several BGA-reated specs.
These include:
MO-149 Tape BGA / square
MO-151 PBGA / square
MO-156 Ceramic BGA / square
MO-157 Ceramic BGA / rectangular
MO-158 Ceramic column Grid Array / square
MO-159 Ceramic Column Grid Array / rectangular
MO-163 PBGA / rectangular
Are there others, someone????
Also, JEDEC procedure SPP-010 specifies use of an alphanumeric system for ID
of BGA balls/columns (very similar to Pin Grid IDs.)
Hope this is of help to you.
Best Regards,
Doug Peck, AEIC
