PoP Process Capabilities
PoP is package-on-package assembly that consists of two or more fine-
pitch ball grid arrays (BGAs) stacked one on top another. In a two-piece as-
sembly, the bottom package is usually a high-density logic device, while the
top package is a high-capacity memory device. Both devices may contain
more than one die.

Engineering Services051 Electronics desires to be involved at the inceptionof the program.The most cost effective time to find and fixdefects is at the initial requirements stage.
We are able to provide this valuable manufac::turing feed-back when provided the following information:
• ASCII Output of the CAD data• Fabrication drawing - DXF,Gerber or PDF• Assembly drawing - DXF,Gerber or PDF• Parts List - .XLS is preferred• Schematic - PDF is preferred
DFM Feedback Example
Hole drilled in SMT pad -this will lead to insufficientsolder, as solder will fill thehole.
051 Electronics recommends removing vias from pads,or add a note on the PCBfabrication drawing indicatingthat the PCBsupplier must epoxy fill the via.
