I pulled out an old Weller WTCPT soldering iron, the type where the tip
controls the temperature, not the one with a digital readout, and was trying
to change out some components on a MIkrotik board. The tip was a 700 degree
1/16" tip. I haven't done much soldering since the world went lead free,
but a 700 degree tip used to be standard in the 60/40 solder world. The
solder on the Mikrotik board just laughed at it. (I was using some small
solder wick.)
Do I need a higher temperature tip, or a bigger tip? Or both?
And can I use 60/40 or 63/37 solder for the new components and clean the
flux off with alcohol like we did in the old days? Will that hurt anything
as long as the RoHS police don't find out?
