Also amazing how small the components (LED dies) are.
> 0402 (1005 metric): 1.0 mm × 0.5 mm (0.039 in × 0.020 in).
There was a reason I did it before I had any coffee!
The pick and place machine needed blank strip of about ten components (just for lead-in on the cassete).
Transfering components from one tape to another was really annoying. And one of the bosses just did not understand that the fractions of a penny saved were obliterated by time wasted moving components over.
And until you've had to do something like that you can't really understand the benefit of $60 Swedish tweezers.
The lady I have hand building my boards can place 0201 all day. Pretty amazing.
(says me who just bought 200 for a small prod run). So that's £10 or £50 out of the budget. Thanks to cheap LED guys, I can take my family out for that extra £40 :)
