What do I need to do and get to fix touch ic
I have a iphone se that I posted about earlier, ill put the link in the description. I watched a video of a person repairing a 5S and he used a heat gun and some brownish liquid substance, but there is no video for repairing the SE touch ic. I do have a soldering iron that can microsolder and I am experienced in soldering but im new to iphone motherboard repair and microsoldering. I am on a tight budget so can I just order the touch ic and fix it or do I need to get a heat gun, the substance?
also Is there a video for repairing the touch ic on my iphone SE?
I already have a lot of supplies for microsoldering except a hot air reflow. soldering paste, and wickets, do ineed those too?
