In my experience, albeit limited, you don't have to have a fancy no-clean flux pen. This one worked perfectly for me: Surface Mount Rework Flux Pen - Jaycar Electronics

I just cleaned the board when i was done with several rinses of 100% isopropyl alcohol and very gentle work with a soft toothbrush.

I butchered the pcm2702 on my first alien dac.. took me maybe 20 minutes, and eventually fried it. I got perfect joints after getting a flux pen.. about 25seconds to solder the pcm onto my first bantam, and 15 seconds for the second and third one. Tweezers and a reasonably fine chisel tip helps as well.
I got all three at mouser.

Am in 2000% agreement on the flux and would suggest the bottle with the needle applicator that Tangent has on his site works even better than the pen.

I grown tired of using my flux pen, I just can't get flux to come out (and I still have a decent amount) and the tip's worn out, often making a massive mess, and is overall a pain to use. But regardless, flux is awesome to have around! I would like to try the one Tangent sells one day...

Anyways, I wanted to do a point-to-point version of the balanced -> single-ended stage for my Opus, and need to make sure the wiring's okay: clicky. It's probably a lot more trouble than it's worth, but we'll see...

I have used a bottle like the one Tangent sells. It is very nice as you can apply a very limited amount of flux.

Looks like the jist of it. Are you using the circuit on the right? From where did you find it?


It's part of the schematics on the first page, second post, I just copy and pasted it so it's easier to compare.

I use the exact same one! It's very easy to control how much flux you apply.
Thou I really want a little squeezy bottle like tangent sells as it looks even better... I wonder if you can get a similar product in au?

Fry's Electronics stores sell liquid flux in bottles with a small brush built-into the cap. I use that now and it works great.

Flux pens also work well, but only when they're new. The flux tend to dry up at the tip, clogging the flow (even when there is plenty left inside). Working the tip sometimes works to get it started again, sometimes not, or you might suddenly unleash too much flux... making a sticky mess.

Can't say I have ever left a flux pen unattended long enough for the tip to dry out.

As much as I hate to sound ungrateful...I threw the bottle of flux I got from Tangent (for free) away after using less then a quarter of it because the solvent had evaporated to the point where it was a exercise in frustration to try use it.

Maybe something like one of those "General" pen oilers is a more suitably sized container for novice DIYers?

chipquik? I think mouser stocks them

Digi-key (#SMD1-ND) or maybe at Fry's if you have one near by (# 2644632)

BTW the flux that comes with that kit is kinda neat because it's tacky but I dunno about the smell.

I meant over the course of several months, not in a single soldering session...
