Could you put a link in for me for the best wick and flux to use on a mobile phone please? Thank you
Just get good quality brands, and in the case of wick, the appropriate size for the joints.
For wick, I'd go with Chemtronics if you can get it. Flux from any of the companies I listed would work.
Personally, I prefer liquid over a pen (more economical than pens; needle bottle or small brush gives you fine control of how much & where). Unfortunately, small quantities of it are harder to find, so MG Chemicals would be your best bet if you go this route (100ml bottles; others, such as Kester 1 gal & larger containers). Pens are much easier and more common to find. Circuit specialists sell refillable pens, so that might be an alternative as well (not sure who manufactures their flux though).
As per type, go with either rosin or no-clean,
but I'd recommend avoiding water soluble flux, as it must be cleaned off quickly (or it will corrode your joints within 24 hrs or so).
Thank you again nanofrog really aplriciate the help
