Premium Grade solder? - Page 4

post #46 of 64
Cardas quad is the way to go for boardwork. It melts and reflows very easily, I build most cables with it. You'd have to be a masochist to want to use Mundorf for much more than plug terminations, it takes an insane amount of heat to melt it. It smells cool, though.

Because it costs more. I'd rather upgrade something in the amp. Hell, I'd rather use a fancier volume knob or something than silver solder.

i noticed that as well.
i used my father's 60/40 and didn't have cold joints.
i bought some 63/37 the other day and had some cold joints

60/40 may flow better but if heated properly a eutectic solder should result in better joints when hand soldering (ie when there is some movement of components as the solder cools).

Cold joints are usually a sign of over heating or lack of flux. (or burning off he flux through overheating). The type, amount, and proper usage of flux make a big difference.

Solder falls into the realm of voodoo science. Pick what works best for you, what you like the smell of or whatever, but if it costs more you're probably overpaying for aesthetic rather than important per function, reasons. Regular 60/40 and 63/37 low cost solder is not hard to use and most people do not hear any audible difference but as Brian Donegan pointed out, the amount and type of flux can vary some so pick based on what you're soldering.

OT of solder type, but a good guide for good and bad things in soldering:

THROUGH-HOLE SOLDERING GENERAL REQUIREMENTS

Note that NASA considers gold in a solder joint to be a contaminant.

i got some cardas solder and they are really nice to work with

Cardas Quad Eucetic is my favorite.

Did anybody work with WBT lead and lead-free solder? Do they both flow equally?

It is interesting that Gold Plating is considered bad as well:

Quote:
UNACCEPTABLE

GOLD PLATING

Gold plated surfaces that will become part of the finished solder connection shall be tinned prior to soldering to remove the gold plating.

NASA-STD-8739.3 [7.2.5.c],[13.6.2.a.3]
So every gold plated board would fail their tests...

i think because the gold is plated :x

well, i don't think any sane human will go for solid gold pins :x

at least gold plated contacts are still good^^
just not for solder joints.

I've only used the WBT leaded solder, it flows REALLY well and absolutely dispels the myth that silver content solder doesn't flow well. That's not to knock 60/40, 63/37, or anything else, but to say that anyone who has actually tried WBT-0800 knows it is very easy to work with, at least for the typical DIY project.

 

The wetting characteristics of WBT-0800 are no doubt a function of the flux formula. As various other posts have pointed out, the flux is a huge part of the equation, that too gets broadly overgeneralized or overlooked when the 60/40 or 63/37 staunch supporters stage their attacks on all silver content solder.

 

I'm not referring to complex board work or anything that would qualify as the intricate professional realm, especially life and death medical devices or NASA space program electronics. But I find most of the digs at, and rejection of something like WBT-0800 are from those that have never actually used it, or those that are fiercely against the pricing.

IMO the only people who are worrying about type of solder are those with the luxury of not having any serious design choices to make.

No one said anyone was "worried".

 

IMO, your post belongs in the "serious designers making serious design choices" thread, as it has nothing to do with solder at all.

 

Why waste your time in a solder thread when you clearly have big design choices to worry about?

 

Go ahead and pat yourself on the back Mr. Serious Designer.
