Talk:Practical Electronics/Soldering

Eutectic solder
The section on Eutectic Solder, as currently written, is NOT nonsense. Eutectic, in materials science terms, means that the combination of constituents in an alloy results in the lowest possible melting point, lower even than the melting points of the constituents in isolation. Like any other alloy, eutectic solder can have a plastic, pasty state and can produce cold and fractured joints. QuicksilverT @ 01:03, 26 September 2008 (UTC)
 * I've had a quick look around and there's several sources that agree with the page as it stands:
 * ,
 * Wikipedia article, which states that eutectic solder has a very well defined melting point rather than a range. This would imply to me (although I'm no materials scientist) that it should solidify instantly on falling below the melting point. The other sources explicitly state this.
 * If the page is wrong, then this is a common misconception, but I've seen no sign of anyone refuting it. Inductiveload (talk) 06:52, 11 June 2009 (UTC)


 * I'm refuting it, as one who has studied materials science, among other subjects, in achieving a degree in electrical engineering. QuicksilverT @ 19:09, 8 January 2010 (UTC)

Troubleshooting section needed
The usefulness of the module would be greatly improved by adding a section, with photos, covering cold joints, fractured joints, dry joints, excessive solder, insufficient solder, and the various other problems that novices are likely to encounter. QuicksilverT @ 19:12, 8 January 2010 (UTC)

Incomprehensible external links
The following was added to External links by user DavidCary on 2010 August 27, 14:48 UTC:
 * Have all MIL Standards been replaced(Mil-Std-100, Mil-Std-275, MIL-STD-2000, etc.) by IPC standards such as IPC 610 Class 3 ?

It's an incomprehensible mish-mash, couched as a question, with bad typography. Maybe DavidCary could take some time to sort it out before attempting to re-add it to the article. &mdash;QuicksilverT @ 16:41, 26 May 2011 (UTC)
