PCB Metal and Components Placement

Evaluations have shown that the best overall performance is achieved using the substrate/PCB

layout as shown in following figures. PQFN devices should be placed to an accuracy of 0.050mm

on both X and Y axes. Self-centering behavior is highly dependent on solders and processes, and

experiments should be run to confirm the limits of self-centering on specific processes. For further

information, please refer to “SupIRBuck™ Multi-Chip Module (MCM) Power Quad Flat No-Lead
