Hi, I currently don't solder the 2020 LEDs myself anymore, I order from internet PCBA... mostly I encounter data/clk pin shorts to Vcc or gnd, which is obvious as I can see the LEDs aren't updating after a specific LED, just check the pins nearby...

Hi, Sorry for the late reply, I somehow missed your answer. I'll give it one last try based on your tips. If it still takes too much time, I'll just order a prebuilt one instead.You're absolutely right that time and effort have value too...

Awsome work!!! I'm currently trying to solder the LED boards and I'm consistently ending up with VCC-GND shorts after reflow. I'm planning to order a new stencil with reduced apertures and thinner steel to get less paste, but some shorts will...
