yes Glenn I am seeing that all boards are not equal. I did not know about different materials thanks for that info. was working on a neato robot vac board and had a problem with burning the board this was before I got a de soldering iron.
when de soldering I start with a little flux I like the fact it marks the joint that needs to be de soldered and hope it protect the board from over heating. is there any thing else I can do to prevent over heating the board? Is the Carver C1 board a good board what is your opinion of it?
Thanks
Robert
