7.1 Land Pad and Stencil Design
Land Pattern Guidelines for BGA-80B ?
The PCB BGA land pads have to be designed to ensure solder joint reliability and provide optimum manufacturability. The two basic types of BGA land pad design are: 1) The Solder mask defined land pad (SMD)
2) The Non-solder mask defined land pad (NSMD); recommended type for PCB ?
The SMD type of BGA land pad design is characterized by the copper pad being larger than the solder mask opening above this pad. Thus the solder joint area of the land pad is defined by the opening in the solder mask.
Stencil Guideline for BGA-80B ?
The stencils for BGA pitches at or below 0.65 mm have to consider other factors as well. Usually on a PCB, there may be other small size and small pitch components which prevent the stencil opening size to be reduced. Instead, the total stencil thickness is decreased. Typically, stencils are from 0.075 to 0.125 mm thick.
