The Benefits of Package-on-Package Assembly

Package-on-Package (PoP) is a type of IC packaging method that combines ball grid array (BGA) packages. In this method, two or more packages are vertically installed (i.e. stacked) with an interface that can direct signals between them.

Package-on-Package assemblyThere are two popular configurations for PoP assemblies:

  • Pure Memory Stacking: multiple memory packages are stacked on each other
  • Mixed Logic-Memory Stacking: a memory package is stacked on top of a CPU package

The packages are stacked on each other and attach to each other during reflow soldering.

There are several advantages PoP assembly has over tradition packaging methods:

  • Package-on-Package assembly more efficiently uses space, as packages are stacked vertically, increasing the effective space on the motherboard. The reduced space requirements for PCB assemblies caused by package-on-package assembly allowed smartphones and other compact electronic devices to achieve higher levels of performance without increasing in size.
  • Package-on-Package assembly also shortens the track length between components, causing better electrical performance as the shorter length will reduce noise and cross talk, and promote faster signal response.
  • Memory packages stacked in this fashion can be tested separately from the CPU package.
  • As long as the memory package fits on the CPU package, any memory package can be used, increasing flexibility in design.

Package-on-Package assembly is a delicate process and you should rely on an experienced and reliable PCB assembler such as IPC A-610 certified company like ACME PCB Assembly to build your products.
