PCB METAL AND COMPONENT 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 (PQFN) Board Mounting
Application Note.” (AN1132)
