Electronics Forum | Mon Dec 17 13:58:54 EST 2007 | ck_the_flip

I made my own wave measuring device using KIC2000 system. KIC2000 has automatic wave detection, so now I have a profiler for both reflow ovens and wave solder. The delmat carrier only cost $500. A guy, Samir, from this forum gave me the idea, actu
