PCB Mounting Recommendations
Board (PCB) reflow processes. For optimal zero-g offset after
PCB mounting, care must be taken to PCB layout and reflow
conditions. Reference application note AN3484 for best
practices to minimize the zero-g offset shift after PCB
mounting.
design. The footprint for the surface mount packages must be
the correct size to ensure proper solder connection interface
between the board and the package.
subjected to a solder reflow process. It is always
recommended to design boards with a solder mask layer to
avoid bridging and shorting between solder pads.
