Hi, I have a problem with removal old pol film during iphone refubrish. Half of them are removing without problem, other half got damages on LCD. For polarizer removal I use YOUYUE 948A machine. Tried to do it slower/faster, changed temperature, use dedicated molds or silicon but still some LCD got damages. Take a look at the attached pictures. I will appreciate for any clue

Hi, A quick Google of the machine you say you use shows it just to be a heated flat plate, so do you use wire to remove polarizer? I use a dedicated Polarizer removal machine (Particularly the OCAMaster OM-C2) which I have used for hundreds of iPhone 7 LCD’s with basically zero broken. I also suggest using a mould to keep the flex in its natural folded position during every stage of refurbishment as these are very fragile and will often cause No touch or lines in the LCD if bent past 90 degrees. Hope this Helps.
