What braid to desolder to clean the pcb iphone motherboard What type of flux to clean pcb connection without damage Flux no clean or Rosin Or find a braid of very good quality clean with iron soldering or hot air if iron soldering what temperature if hot air what temperature (my station is three picture) I am glad that there is very great profesionel on this forum Thanks to them all
I use Tenma, Size #1 Width .035" (0.9mm) Part# 21-8355 but any good quality thin braid of same size with flux would work. Thicker braids tend to be a little harsh and just move the solder instead of soaking up like the really fine braid. An alternative I have used is to cut a 1 inch piece of braid and hold it in your tweezers. cover all other areas with Kapton tape except area you are working on to 1. protect other components from heat and 2. to keep the other components from moving. put flux down on pads working on and focus heat on braid. then using wick like a paint brush, lightly brush solder (Do not brush against other components) and it will soak up. I keep a few cut pieces near by to change up after piece is full of solder on tip. Just try to keep it short as an iron is better to focus heat on area you are working on and the hot air is indiscriminate and too much heat is not good for the board or for the components surrounding the area you are working on or the reverse side.
