I am a beginner at soldering and am trying to assemble a number of these small pcbs. In the process, I have to solder SK6812 MINI-E LEDs and am struggeling to get that right. My problem is that the LEDs tabs are almost exactly as large as the solder pads on the PCBs and if I apply solder and flux to the pads and try to use hot air to settle the tabs into place, they tend not to stick to the pads and if I try to put them in "dry" and solder them with the soldering iron (like a through hole connection), I have trouble getting solder between the tab and the pads. Any advice? Any video that shows how to solder this kind of joint?
