MicroBGA is a package name that is Trademarked by Tessera.  Packages that
are sold as microBGA must be either made by Tessera or licensed by Tessera
to build microBGA.

These packages vary in body size, lead count, and lead pitch.  The micro BGA
packages are used for flash memory and Rambus memory devices, to name a few.

The technology of the package and how it is built defines microBGA.  I would
check with Tessera (www.tessera.com) for more information.

Subject: [TN] Micro-BGA definition?


Hello technetters,

How is micro-BGA defined in the industry? By body size, pitch and/or ball
size?

What is the IPC referring document for this definition?

Thanks in advance,
