1. The marking codes can be rotated by 90 ° or 180° to differentiate assembly location. In no case should this
product marking be used to orient the component for its placement on a PCB. Only pin 1 mark is to be used
for this purpose.

PCB design preference
1.
To control the solder paste amount, the closed via is recommended instead of open
vias.
2.
The position of tracks and open vias in the solder area should be well balanced. The
symmetrical layout is recommended, in case any tilt phenomena caused by
asymmetrical solder paste amount due to the solder flow away.

Minimize air convection currents in the reflow oven to avoid component movement.
