Which solder paste for LED reflow?

I don’t even use solder paste. I use the same solder that I use with my iron, Kester 44.

I clean the old solder off the pad then add flux and solder with my iron. Then more flux and put the led on top and heat the mcpcb up again.

The thing about pastes is they go bad over time and then don’t work well. I’d rather have the reliable spool and do the extra step. Just my opinion.

How do you reflow? If you are using hot air for a PCB or hot plate for MCPCB paste is really helpful. I have been using the same cheap syringes of paste for a few years now without issues.

Hot air.

A lot of pastes technically expire like 6-9 months after date of manufacture. I rarely reflow stuff, so that paste just goes to waste with me. I’m also not real comfortable using it after the expire date. It’s probably okay, but eh.
