The SMD stuff is new to me. I’m getting the hang of it. I’m using a soldering iron. I really need a smaller tip. The one I have works, but tip seems a little too blunt for this kind of work.
Flux is important. I have been using liquid flux. I also bought some paste which I might test.
You really need very little solder on the tip. Just a tiny bit, if you can see solder on the tip it’s pro too much. Like vermouth and gin.
Some fine tweezers are essential for getting parts on to the board. I use a dental tool to hold the part in place then touch the pad with the iron. I have a magnifier lamp that helps see what’s going on.
I don’t fully trust my work yet. The parts are so small it’s hard to inspect the joints. I tes each resistor with the multimeter at traces connected to it after each is soldered.
