Flux Pen?

jschristian44 · 22nd January 2012, 02:22 PM

What is the Flux Pen for? I was told you put it on the PCB board in the middle of very tiny pieces and they will stick to it. I tried this and it doesn't work. And yes, I pushed it down at first and it came out. I have this:

It's to help with soldering. Use the pen to put some flux on the copper, then it will be easier to solder onto the copper.

Oh alright that sounds good, I will try it then.

I've only soldered for decades.

If the flux isn't in the solder, check back after decades.

There is a ton of reflow work, all that surface mount stuff for example, where you are not feeding solder from a roll into each joint. A dose of flux on the board before soldering down a huge LSI makes it a lot easier.
