I bought a Hakko desoldering gun and would never part with it. I don’t waste my time with wick anymore, unless I really need it. Sent from my iPhone using Tapatalk |

I've ripped up pads and traces by accident with wick. Scary stuff. Got to be careful with it. |

You guys rock. Thank you all very much for the info. :cheers: My sister got me the coolest pair of 3M glasses that have led lights on the temples AND magnify too, so maybe my 50 yr old eyes can see what the hell I'm doing. I could be imagining it, but I would swear that using denatured alcohol to prep solder areas made my soldering better. Desoldering wick I have used, but sometimes it seems like it takes an uncomfortable amount of heat to get old crap off. I'm new at it, so still not sure what stuff can tolerate for heat. I did keep some old boards out of stuff to be tossed so I can practice on some cadavers. The old Weller I have has worked for what I have done previously, but I need to look up the Hakko units and Panavice too. I don't want to butcher these chassis (I have two Sharp Image and two Kortek that need help) so all help is very meaningful. Mahalo nui loa! Bobby |

I should do that more often ::) --- Quote ---Desoldering wick I have used, but sometimes it seems like it takes an uncomfortable amount of heat to get old crap off.

I often have similar problems using the fine solder tip that I use to solder tiny things with, it just doesn't transfer enough heat to the wick. So now I keep another iron handy, a Hakko Presto 20/130W iron with a fat tip (so I don't need to change tips) for those dirty jobs. Solder flux (liquid kind) can help too, soak the braid in it (drop or two from the little bottles Vigo mentioned/linked earlier). |

It's always the nuance of these things that makes the difference in how it goes. The heat transfer thing... makes so much sense. I've watched a few guys who were VERY good weld aluminum- and that is art. Being able to see how fast something can absorb (and also dump) heat, and the difference between doing it right and wrong was an eye opener for me in regard to real welding (and speaks to soldering too then of course.) I can put a car exhaust back together (and not beautifully at that) and sweat water pipes too, but I can't ever see having the skill to weld aluminum. Hopefully I can sort out electrical solder! ;D |
