    • Too much head risks melting the micro-welds on the Trackpad, so be cautious with the use of a heat gun.

    • Be careful not to damage the Trackpad when taking it off. Although it is a relatively solid part, the glue is present on a large part of its surface and is strongly adhered. You can see the adhesive strip on a new part.
