Just wanted to note, we did a rigid PCB demo board with 64 APA102Cs and it is clear the APA102Cs are very delicate compared to even other LEDs. I believe we will need to utilize a lower temperature solder or improve our reflow oven's timing. We ended up needing to rework many APA102Cs and re-reworking some. The demo proved our concept though, so we will next be producing hand etched flexible PCB prototypes.
