@smartieoncomputer solder mask, it's not that common to find it at solder resist, at least most places I see I find like that, including people, tutorials and suppliers... wte, just pointing out that, not offensive or anything =)

This is simple, when the solder melts it gets pulled into the pads by some force ... forgot the name of it. Basically if you use too much solder it will bridge and cause a short. But if you use the right amount or a bit less then it will only stick to the pads.
Basically The PADS attract the solder.The plan board does not.

How does the solder past not short the IC's connections when you smear it like that?

Hey atomsoft, what is your rate of success in these procedures? Did you apply it to chips with ceter square on the bottom? Did you have any issues with solder bridge on the pins, making an unwanted short? Thx

@tiagofumo
98% rate.. some times i get a bridge but on the OUTSIDE where i can see. I usually fix it with FLUX and a CLEANED Soldering iron. Then alcohol to clean entire thing. I check with a hand held microscope from radio shack... i check every pin on the entire board. Takes only 2 minutes on larger boards... Its worth it.

@AtomSoft
The force is called Surface Tension :P
and the purple mask on your board is called "Solder resit" which repels solder.
:)
