hello, its been sometime since the part was drawn,
just here to show that the footprint of 2020 is tested
the apa102-2020 is from TW, those are not friendly to hand solder, or impossible?
I met more problem on stencil + hot plate soldering,
but finally can get a chain with 80 -2020s working
there are apa102-5050 prototype at left (with density of 2LED/cm)
and apa102-2020 prototype at right (with density of 4LED/cm)
here is a working video of two
Thanks for everyone helped
