It’s Manufacturing Monday at Adafruit!
The KISS102 Selective Solder machine is an essential component of Adafruit’s machine line, and one that requires consistent attention. The KISS102 contains a pot of molten solder which must be regularly cleaned. In the video you can see “dross”, a layer of scum formed from oxides and other debris, being scraped off the surface of the pool of molten solder. We clean this machine before and after every use to make sure it’s always in top notch soldering condition.
