Thanks, everything is starting to make sense. What tip is good for SMD soldering? I know smd soldering is for the pros and the experienced, but i am just asking because smd looks a lot cheaper and smaller when finished. MT1 and chisel tip looks good, but which is the easiest to use? I will also stay away form pointy tips because i heard they dont transfer heat very well.
Not sure of the exact iron you have, but if it's what I think, there's only 4 tips offered anyway (MT1 = conical, MT2 & MT3 = chisel, HK11 = knife). You'd want to get both chisels to give you some options for better sizing of the tip to the pad, and the knife blade would be usable for drag soldering.
As per SMD, it just needs a bit of practice, just like thru-hole does. If anything, it's actually a bit easier IMHO, as you don't have to flip the board over and worry about parts falling out like you do with thru-hole. Drag soldering might take the longest to perfect, but it's quite doable as well (good quality supplies really help here).
Where it can get difficult, is when the packages are really tiny. 0402 is probably about as small as most can go without magnification and still get good joints (assumes good eyesight).
Is stainless steel sponges good for cleaning irons? The ones you use for pans and stuff.
I'd stay away from it. Bit too abrasive IMHO, and no flux (good quality ones for soldering tend to have flux on the wool). Brass is softer than steel.
