I finally gave flux a real chance on my solder jobs
I used to skip flux because I thought my iron was hot enough for clean connections. After a messy board fix, I tried it and saw how it cleans surfaces and stops bridges. Do you use flux every time, or only for tricky spots?
Honestly the biggest thing for me is how it saves time on cleanup. Without flux you get that crusty residue anyway. With the right flux, a quick wipe with alcohol and the board looks factory fresh. Stops that white haze from forming under components later. Makes rework so much less of a headache.
Skipping flux because your iron is hot is like baking without flour, it just doesn't work right. Morgany23 called it, flux is a must-have for any soldering, not just tricky spots. Once you see that clean flow, you'll never go back to dry joints.
