Immersion tin is very sensitive for handling, scratches, storage condition and time, thermal influence and washing. You will get problems in second reflow if you have double sided PCB with immersion tin surface finish.

Every thing you need is in "links" here http://packaging.hp.com/. The only thing you need to do now is find it. Ah, so much information, so little time. Yeh yeh yeh, nice little ESD bags are good. Er, maybe sealed barrier bags might be better. E

I'm working on A DEK 265 Horizon and I need to convert it to right to left. I have changed the conveyor direction in software, however, the board stop position appears to be from 0 to 255 and I need it stop on the left hand side of the centre referen

Shadowing sounds about right to me also. Really dicey experiment to run if you are dropping expensive tantalums just to save a little coin in epoxy and processing time.

OK, I'll bite. How you can set a stencil down on a printed board and run a squeegee across it (even if it's a proflow head, it's still a squeegee, right?) without disturbing the printed paste?

... and don't forget proper stencil alignment. Invariably I find most bridging problems for fine pitch parts, etc. is caused by lousy alignment. The alignment must be verified under magnification, using the naked eye is not good enough. Use at least
