Review on SRA Rosin Paste Flux 135: Unbeatable Flux for Optimal Soldering Performance by Tio Kotaki

Flux and tip can are great! I find that flux is much easier to apply when it's warm and melted. To do this, I dip and pull the hot soldering tip into the flux container very quickly (be careful, if the tip is in a hotter position the flux can splatter!), and this makes it chubby enough that I can easily pick it up and apply it . I use a small piece of dry sponge to soak up some of the melted flux and then apply it with a brush. For a diode lead, for example, I can just dip a wire in melted flux to lightly coat it. For the tip can, I dip the hot tip into the container, then gently roll it back and forth, gently pulling the tip in and out. from a container. Then I wipe off the residue with a damp sponge as suggested. This tin works really well once you repeat the process a few times. It didn't work well with just one use, but after 3-4 more iterations it tinned the tip very well and the solder started to build up on the tip instead of rolling off like it would with an untinned tip. It is normal that there are solder balls after using the tin container. It vaporizes the acid and then leaves the tin material in balls that resemble solder balls. As I said, don't worry, it's normal. So here it is! This stuff works as intended, but you may have to find methods that work best for you!
