Heat. We use it for all of our tablet repairs, and also some of our Android phone repairs as well. Using heat properly will make help the entire process go much more smoothly.
When applying heat to your iPad, you can be fairly liberal. The key is keeping the heat focused away from the LCD and on the frame itself. Using brushing motions also helps to disperse the heat across the iPad frame and adhesive. This allows for more area to be covered when you switch from your heat gun to your pry tool.
Once proper heat has been applied, slip a metal pry tool between the glass digitizer and the frame of the iPad. Begin sliding the tool the length of the iPad. It should move fairly easily with little resistance. If you have to strong-arm it to push through the adhesive, you may need to apply more heat. If there isn’t enough heat applied to the glass (and adhesive), you risk cracking the digitizer, which only makes it that much tougher to get the screen removed.
The ReNū iPad digitizers have heat-activated adhesive installed on them, so don’t forget to apply heat prior to installing a new digitizer. Without applying this heat to the adhesive, it will not create a strong bond. Before laying your fresh ReNu digitizer onto the iPad, apply heat directly to the adhesive (from the inside). You will once again use a brushing motion to spread the heat across the edges. Once heated, this adhesive is ready to go! After laying it onto the frame, apply pressure around the edges. Maintaining pressure until the screen and adhesive has cooled will maximize the bond.
I will use a Samsung Galaxy for an example of a phone repair that requires the use of a heat gun. Working Galaxy LCD’s for are worth a substantial amount of money if you can salvage them for an LCD Buy Back program. Unfortunately, the way that these screens are adhered to the device makes safe removal a bit more difficult. In order to loosen the adhesive on these screens, you will need to heat the entire screen area. (This heat will decrease the likelihood of the LCD screen cracking upon removal.) Once heated, slowly and gently use a pry tool to release the screen from the frame behind it. While the heat will assist in loosening the adhesive, excessive heat will risk damage to the LCD itself. Finding a good balance between heat and finesse will lead you to success in safely removing these screens.
