Premium Grade solder? - Page 3

post #31 of 64
Haven't tried it yet, but I might just get some next week or so..
I gotta say I love the premium solder! It melts at low temperatures and thus less heat to potentially destroy the heat sensitive materials

Buy some here:
Mundorf M-Solder Silver/Gold Solder x1 Meter - eBay (item 220380087175 end time Jul-16-09 03:54:06 PDT)

I haven't tried it yet. I got a small roll of Tri and Quad solder from Cardas and I am very impressed with that stuff. You can move very fast soldering as it heats and runs so easily just makes such nice joints.
I have been testing various solder lately but I haven't got to the Mundorf Supreme yet. I will have to get some, thx for reminding.

ROBSCIX, did you try Mundorf Supreme? I recieved 3m Mundorf Silver/Gold and I have mixed impressions about it.
It doesn't flow very easily, at least not for me when I was soldering 2 sided PCB. It ran to other side only when I had clean tip and when I melted it directly on hole. If I had solder on tip, then it stayed just on one side.

And forgot to ask... Is there any lead free solder which flows well?

i use mundorf supreme, the one with 9.5% silver, but its only good for point to point soldering esp in tube amps etc. it only flows well when you have the iron heated to 300+ degs, if you dont have a temperature controllable iron, you can consider irons above 40 watts.

you risk overheating components if you're not quick enough. it solidifies in a quick instant due to its high melting point, so i usually dab the solder on and blow at it immediately after application.

for PCB based or solid state electronics, i would still suggest something like tri eutectic w/o lead or with if you like. this solder will be too hard to work with, esp with the need of a fine tipped iron on PCBs, you wont get good flow, and probably lots of bad joints

Well I also have ETI silver solder(5% silver) and I use it only for P2P soldering as it flows very poor.

vajrasattva did you work with any lead free solder?
post #39 of 64
Mundorf Supreme is lead free. Personally, I think it has an extremely high melting point, so I only use it for non-sensitive components (interconnects, etc.). Otherwise, I stick with my 63/37 or my 62/36/2. I personally found them all to sound the same. If I had to buy more, I'd stick with the 63/37. Easy to use (I don't really like 60/40, doesn't flow as well) and cheap. I bought the 62/36/2 out of curiosity, but it flows about the same but takes a slightly higher temperature to melt (and is more expensive to boot!). The Mundorf solder was a gift (so I have to like it the best ), but I wouldn't recommend it unless you HAVE to have lead-free solder (of which the Mundorf was easiest to use; then again, I only had crap that came with cheap soldering iron).

Thanks for reply. As I live in EU, in few years leaded solders will most probably be history and that's why I'm asking if there is any lead free solder that melts and flows well.
How did you compare 63/37 and 62/36/2 solders?

They both flowed quite well (but they're both leaded), but it feels to me that the 62/36/2 has a higher melting point. I'd just stick with the 63/37. Of all things to get boutique items for, solder is the very last thing on my list. As Uncle Erik said, solder is there to provide a conducting, mechanical connection. Priority should be on ease of use and cost efficiency.

I totally agree with you. But if you're building amplifier with expensive parts, why not solder with silver.

yup i do, cardas tri-eutectic is lead free. the Quad eutectic contains lead, tri doesnt. you can buy shorter lengths (i.e. 100grams etc) off ebay or some online shop i.e. hifi collective, parts connexion etc

i typically prefer to use the mundorf supreme solder only when i'm working with mundorf 1% gold wires, else for copper or anything else normal solder will be fine.

the rosin in the mundorf solder smells less offensive than others that i've used though i.e. wonder solder
post #44 of 64
I'm using Wonder Solder that I got from Michael Percy Audio a few years back... works great. Apparently it's a 'secret' blend BTW - I just checked his most recent catalog and it's still listed - several flavors now

I too use liquid flux - got it from Tangent... SMD soldering is, for me, impossible without it.

I use kester 62/36/2 it works pretty well for me i like it much better than the 60/40 solder.

it flows pretty well and makes good joints
