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
