[Update] hand soldered board

This one is almost as big as the small 20mm x 20mm, inspired by @al1 's visit at my place, showing of his colourful and tiny RGB displays. I plan on putting this on arduinos and just run and hope for the best with blue or white LEDs.

don't be cheap, use fresh solder paste :D first heatgun station (858D) clone test.

I needed something to calm down my nerves - the annoying colleague was annoying - so I hand soldered the board with the today arrived UV LEDs. I wanted purple leds on a purple board...

ah hah! If that's what happens with old solder-paste, then no wonder I've always had so much trouble with it I thought it amazing anyone could use it. Musta got some old-stock... 'cause that's basically exactly what my experience has been... but not nearly to such a scale ;)
