Burn from Soldering Iron or Measling ??

Electronics Forum | Thu May 14 18:45:15 EDT 2009 | jax

I am having trouble determining what the IPC classification is for the attachment. Also... if a burn, is it a defect and for what classes? Thanks

0201 Rework

Electronics Forum | Wed Aug 26 15:47:37 EDT 2009 | stepheniii

Are there solering iron tips for that size component? The C shape end ones. That might be even easier than cutting them first. I would think hand repair is going to be better than a semi-automated repair station for a while.

Mysterious reflow problem

Does the established joint still exist if once again re-touched by a soldering iron, or does it return to the original problem? Wetting issues on pad could be for many reasons and you could analyze with a cause effect diagram.

Lead Free solder

Some companies claimed their lead free solders wouldnt attack stainless steel, frankly they do and they should not be allowed to get away with these claims. Lead Free does not attack Cast iron

SN96 solderability on electrolytic tin

Electronics Forum | Tue Nov 24 19:17:29 EST 2009 | gregoryyork

It could be that the Sn96 has dissolved the Tin rapidly and gone for the Copper. What dwell times are they using with the irons? Probably better off using a Tin Copper alloy for reduced dissolution worth a try Cheers Greg

hi peter, i have experience with manual soldering iron using automated wire feed,please email to me about it in detail,thank you.email:steven@ludeecircuits.com

ceramic cap crack

Dennis: These "terminal detach failures" probably are caused by thermal shocking of the components. * Preheat the components * Use a hot air pencil rather than a soldering iron

Fiducials

What type of finish are the PCB's? HASL, tin immersion, silver immersion,........we've seen all the above problems with HASL finished boards. Usually either reheating w/ a soldering iron or "burnishing" with a scotch brite pad has worked for us.

Solderability Issues

Electronics Forum | Wed Jul 28 09:15:46 EDT 2010 | vetteboy86

I took a pad that did not have any solder flow (wetting issue with pad) and not reworkable with soldering iron, and scraped with an exacto knife. After scraping the pad soldered fine. Any suggestions?

Soldering equipment

Besides selecting an efficient soldering station, the geometry of the iron tip and its maintenance thereafter is extremely critical to equipment performance during the soldering process.
