@bigbulb

Hand soldering SMT? That's really hardcore! Maybe in my youth but these days with my "mature" eyes and hands I'm lucky if I manage to plug circuit boards together without mis-aligning the connectors  Confused

Your results look great.

Thanks!
well, I'm not young anymore, I'm using a magnifying glass / a loupe (and my shaky hands)  . 
I finished up 5 units in 4 days, need a good rest before continue assemble the rest of boards.
