The surface tension of lead free solder alloys doesn't self align as well as it does with leaded alloys. Taking the guesswork out of alignment would negate the need for expensive split vision systems and make the parts hand reworkable.

I have heard there is a process for mitigating the pure tin issues for 0402/0201 size parts by the use of SN63/PB37 solder print process. Is this true and does anyone have the data to back this up?

You're thinking correctly in trying to improve your process. Can you change to a more active flux? Look at the copper that connects to the center pin. You may need to relay-out the board to add a wagon wheel style thermal relief in that area.

We just got a wave solder machine and we are using Sn100. I am new to the wave process. I see a product called "Super Deox Dross Reducer". Is this something we should be using? Is there a downside? Better alternatives? Thanks!

Polymide is like a sponge and absorbs moisture much faster than rigid substrates. Pre-bake your substrate for 2-4 hours at 125C and perform your soldering within 1 shift thereafter or seal in moisture barrier bags.

Sizzling would be hard to hear our machine has forced air preheaters along with all the other ambient noise, so I'm going to say no sizzling. I've tried really slowing the conveyor down to see if it helped, I saw no noticeable difference.
