what is the best solder to use on PCB boards

[kellogs]

Good morning i am just about to start building my new surf pi i used .60 resin cord solder on other jobs i have done works well i have been told that the residue flux can affect the PCB board if you don't clean it all off as i am new to this could some of you chaps that have the experience give me some advice.Regards Kellogs.

Hi kellogs; the 60/40 rosin core solder cleans well with 91% Isopropyl Alcohol, the kind you use for cleaning cuts and abrasions. It comes in different % ratings so use the stronger for less work. I use a toothbrush and cotton tipped applicator to clean around every solder connection. A side benefit is that you will catch any missed solder joints or notice bad or cold solder joints as you clean the board.

Hi kellogs, good to see you back, I look forward to you getting a successful build. I built the Minipulse Mini kit. It works fine on the bench. I am experimenting with different coils and other ideas. Need to add some kind of ground balance circuit before putting it into a box for field testing.
