Looks like you need to get a jig to hold them down on the board too. It looks like the 0603 is good, but the 0402 is a little canted, and the microscopic one is tipped pretty good. Seems to be the break point where I was running into problems keeping them straight and tight too, but I'm only planning on going 0201 as the smallest. I just don't have the dexterity in my fingers anymore. The microscope is in the works, just haven't gotten around to it yet,...work comes first.
Just need to increase size of pads so that I can put more solder and surface tension will do better job, apparently it takes some effort from PCB fab house too, in orded for this 008004 to work better I will have to reduce the gap between pads to about 3mils, currently it is about 6 mil so 008001 part is not laying flat and one end of it always falls into the gap, sending new board design with pads a bit closet together and larger, that should work, same for 01005, will be fun project again, I may throw 1206 cap in there too and line them up so it will make nice visual reference from 1206 down to 008004.
How do they even deposit solder paste to such small pads in real production world?
