So I am trying to solder a wire to a PSB board. Here is a image of a different person doing it: http://www.instructables.com/files/deriv/F6G/IBR1/GREPYEFM/F6GIBR1GREPYEFM.LARGE.jpg But when I try to do it the solder does not stick to the PCB. What flux would be best for this? I am fairly new to this and if you could possibly send me a link to where I can buy the one I need, that would help :)
So basically I am asking is, what flux would be best for what I am trying to do? Are all fluxes the same? Are some better than others?
I am new to using flux, and is it also possible I could pick it up from a store like radio shack?
Also if the liquid flux is good for this project, will it be good for other things? Like connecting to wires together?
