[quote]QUOTE: <i>Originally posted by lupo</i> <br /><br />gsetter, you seem to know a lot about soldering, I once was told that when the parts you soldered the tin looks dull after cooling that joint is not good, it should look shiny after cooling. <br />do you know anything about that? <br />thanks <br />LUPO <br />[/quote] <br /> I've had plenty of practice. <br /> A dull solder joint is sometimes called a cold joint or bond. What happend was not enough heat was applied and the metal / solder cooled too fast and / or the parts moved while cooling down. Always let the joint cool down compleatly before moving it. Reheating the joint and securing the parts (clamp of some sort) to prevent movement will fix the bond. <br /> However, if the solder doesn't look as shiny as polished aluminum it doesn't necessarily mean it's a bad bond. It should at least look somewhat shiny but not like flat aluminum or dull gray. Allways test you work before puting it into service. <br /> <br /> G.
