The tricky thing sometimes is determining between "what's best" and "what's best/good enough for my use".
Obviously there's a huge difference in equipment needs for a professional who uses these tools heavily every day and a hobbyist as myself who works on the occasional projects for personal use. From what I've learnt so far it appears the Ersa I-Con Nano Mk2 will be a very big improvement over what I've been using all these years (30W or 40W soldering irons and mostly the same type of pencil tip) and probably more than good enough for hobbyist needs. Agreed?
With the caveat that hobbyist and professional needs are often not
that far apart -- I am an advocate of using good tools for your hobbies -- I fundamentally agree. The whole package is what matters, not necessarily one spec above all else.
Going from a "fire stick" with single tip to a modern soldering station will be a
revelation. At least that's how it was for me when I got my i-Con nano. Going from the nano to JBC at my old work? A little better, but not groundbreaking.
IMHO, for most purposes, once you're in the world of name-brand soldering stations, the choice of tip will make a bigger difference than whether it's an Ersa, JBC, Pace, or Weller. Matching the tip to the job makes all the difference.
PS: the guide refers to P.W.B. ("Consider the size and shape of the P.W.B. and components for their thermal mass carefully, and select the soldering tip that fits with them well."). Does anyone know what this means?
PWB = printed wiring board.
Aha! I've never heard that term before, always referring to "printed circuit board" or "PCB". Thanks for clearing that up
Another term you may encounter is PCA: printed circuit assembly. This means specifically a PCB that has the components populated. (In that case, then "PCB" is used to mean specifically the board itself,
without the components.) Sometimes you see PCBA (printed circuit board assembly) to mean the populated board.
Analogous to this, you occasionally see PWA (printed wiring assembly) to mean the populated board.
