It's easy to hand-solder smt parts - you just need flux, tiny solder, and a good iron.Then you are either wiring them dead-bug style or soldering them down to a circuit designed for them. Youtube has a lot of videos on smt soldering.iceng: There are RGB that have 3 separate anode/cathode connections if you want to do some fancy matrixing, but you are right - usually you get common cathode or anode for a 4 pin package.

+1 Live and learn 6 pin RGB LEDs wowee If you come across a source link please copy me with it :) I still want to caution 21century about over heating the BLUE LED pins when dead-bug style or soldering. It would be a shame to lose a whole LED for a touchy blue diode. Like tonight installing a blue LED sign for air flow on my plasma cutter got overheated from shrink-tube and I had to rewire that LED a second time being carefullest heatsinkinging the led when heating.....

You don't...The RGB LED ( weather common anode or common cathode ) are not arranged for series wiring because the three LEDs are connected to a single terminal on one side. This is true for SMD parts and through hole parts.If you want to make a series RGB you need to use individual Red, Greenand Blue LEDs....A
I got that but how do I solder such small connectors?
The same way as all other SMT parts can be soldered to a PCB. A hot plate with solder paste is the DIY way. I layout my smt pads with extra area to permit side solder in-flow and use something like a princess solder iron and can do 25 mil spacing. A
