Why should the touchscreen of a phone or tablet (glued only along the contour) be heated with a hairdryer during dismantling?

Question

Do it yourself

I think he sticks out just fine. The thermal conductivity of plastic is crappy, and I personally came across such glue that somehow it didn’t help much. It overheated, and the body was already a bit moved, but it still had to be torn off with force.

Answer 1

so that during removal the touchscreen does not break at the slightest bend

Answer 2

The heat softens the adhesive that holds the glass to the case. After that, it is hooked over the edge and gently lifted, either by cutting the remaining glue (thick adhesive tape) or by helping the glue to separate from the body / glass with a spatula (thin adhesive tape).

Answer 3

no, you don’t need to heat it - just a little solvent or white spirit
