Cardas Audio Rosin Flux 焊接膏 57g

The 57g jar is plenty for a bunch of cable repairs, and the paste spreads evenly without drying out mid-solder. My joints come out shinier and cleaner than with the liquid flux I used before, and it doesn't leave that sticky mess behind.

Finally, a flux that actually makes my solder joints flow smoothly instead of balling up. The activated rosin formula in this 57g jar is perfect for delicate audio work.

The 57g jar is a solid size for bench work, and this activated rosin flux handles tarnished joints noticeably better than the generic paste I was using before. It’s a bit sticky to clean off afterward, but the solder flows so smoothly that it’s worth the extra wipe-down.
