I agree with all of the other comments about iron temperature. I used 800 degrees as standard and had no trouble. The only exception was when soldering the big final transistor pads. There I used the same temperature but switched to a wider tip since my regular tip couldn't transfer enough heat to overcome the considerable heat sinking effect of the wider pads.
Another advantage of 800 degrees was that iron to part contact tip was minimized and that was all to the good.

Hi again, just took a photo. You see it seems to affect only a special kind of hole (see picture). You can see on the picture that other holes work well. http://www.gs-roboter.de/problem.htm Iron is temp regulated at 330 deg C. Same like before. I already changed iron and solder. To no avail. 73 again. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list. Subscriber Info (Addr.
