solder tip size for PC work

[mozarti]

I was just about to solder my C4S printed circuit, and I began to wonder that the tip of my weller soldering iron (.063" x 1.6mm) might be too big and that by accident I might melt the board. Does anyone know the ideal size for work on PC work? Thank you.

I find a 2mm chisel tip is the best for through hole PCB components.

PC boards don't melt, but a big tip can make it difficult to get into a tight spot. I suggest buying  couple of different tips and finding which one works for you. I prefer a pencil type tip for PC work but most seem to prefer something a little bit fatter. A 2mm tip is a good suggestion

I use a chisel or screwdriver point on my iron.  It is small enough I can get one edge on the PCB trace and the other on the component lead.  You want heat into both so the solder bonds them together.

I solder more often than the instructions call for just to keep the leads out of my way while soldering.

Thank you, all three of you, for your helpful advice.

Well yeah, but for decades I used a 300-watt soldering gun for practically everything. (For really fine stuff I had an old woodburning kit.) I'm not exactly picky!
