I always put the step on the squeegee side. You'll get some "shadowing" effect on any parts in close proximity to the stepped up region. It should be manageable with proper board / stencil design.

In the future, please try to explain the situation with some detail. Usually this is the sensor on the 10th station to verify to nozzles are in the up position.

The solder in MB become to yellowish after thermal test (100 oC/12HR) I think the problem that is flux residue and I really want to know the principle that why it color change Thanks!!

Turns out the seal was being broken from poor handling allowing moisture in. Thanks for all the info pointing me in the right direction!!

I would consider to have mask in between the leads and have it open a little bit more than the copper Thank you. That is exactly what the NSMD pad is!

Yes, but I have seen designs where the whole row of leads has no mask(which is also a NSMD)

If at all possible, you definately want solder mask defined pads. Without it, you will struggle with solder bridging. This is especially important if you have a larger size board.
