I have a question my friend
I just repaired a u2 ic on iphone 6
I wanted to ask you if the original glue black on u2 ic on the picture 1
Question: what is it used for
To solidify the weld ??
If so I can put uv solder mask as in picture 2
Mise à jour (29/07/2017)
Thank you my friend for your answer then I can cover the u2 ic with mechanic uv solder mask (green color)
For welding to be consolidated
see picture for example
Is this a good question?
