Silver Solder ?

Silver Solder ?
Does silver solder require more heat to solder and de-solder ?
Tryin to de-solder a dc power jack on a circuit board and the solder wont liquify.
Any ideas are appreciated.

RE: Silver Solder ?
Stay-brite is not true silver solder, it is partially silver solder and flows at a lower temperature than true silver solder. True silver solder almost always requires a torch for good application. Stay-brite does require a higher temperature than a tin/lead solder does but not very much higher. If you are using Stay-brite, be sure to clean the flux very well after soldering as it is an acid base flux and any residue will cause corrosion.

RE: Silver Solder ?
Not sure what this solder is on this board but its very hard to liquify.
I dont have any problem on another board so its not the iron...I dont think.
chisel tip usually works better but im useing a pincil tip because its a small & tight area.
Probally need a smaller chisel tip!

The solder on the board your working on is most likely lead free solder[:'(][&o]
Lead free solder melts at around 425 F. The standard 60/40, or 63/37 Tin/Lead solder has a melting point of 361-374 F
I've been frustrated at times doing repairs on electronics that are soldered with the lead free stuff. If anyone else has more experience with dealing with the stuff, I could sure use some tips
No, not for the iron, I have plenty of them[:-]

Just got a can of soldering flux from radio shack,
Is it me or does the paste flux actually help transfer the heat ?
It seemed that it heated the wires much quicker.
Not a pro here...just learnin as I go.

You would almost never find true high temp silver solder used in any electronic application though I have found it in very high power broadcast and communications transmitters before. Low temp silver solders can be quite common though the lead free ROHS approved solders now prevail most everywhere now. Sometimes they don't melt when removed, they crumble off and require extensive cleaning before a repair can be accomplished.
Oh yes, when using Stay-brite I prefer to use a much lower corrosive flux than what comes with the solder. Any good paste flux available in the plumbing section of a good hardware store works well without the rust and corrosion that Stay-brite flux can cause.

The next time I break out the Stay-brite, I'll definitely get out the can of Oatey paste flux that I use for plumbing. The liquid that comes with the Stay-brite is noxious if you get a whiff of the fumes[:'(]
