The memory encapsulated by BGA technology can increase the memory capacity by two to three times without changing the volume of the memory. Compared with TSOP, BGA has a smaller volume, better heat dissipation performance and electrical performance. BGA packaging technology has greatly improved the storage capacity per square inch, using BGA packaging technology memory products under the same capacity, the volume is only one-third of TSOP packaging; In addition, compared with the traditional TSOP package, the BGA package has a more rapid and effective heat dissipation way.
