Subject: Re: Odd Soldering Tip Behavior

I bought the iron about 15 years ago at the Tektronics surplus store
in Beaverton, OR. Since then it has been my primary circuitboard
iron. It heats in 40 seconds and has handled everything from 1208 smt
chips to .025 square pins to circuitboards. I bought a new 1/16 inch
tip for the iron so I could better handle SOIC chips when this problem
arose.
