Hi guys. Ok ok I know you can buy the adhesive strips to re attach the LCD I have tried several now from different suppliers but they all fail some literally within hours. Has as anyone found a supplier to any that actually stick it down & could you share please? Cheers guys.
All adhesives have a weak point! Thats the surface they are trying to adhere. I’m sure thats what you are facing a dirty surface! What you use to prep the surface could be leaving an oily film or other material thats interfering with the adhesion. I use a three step process to make sure the surfaces are clean. The first is using distilled water, Yep water! Using a shop wipe and/or cotton swab I go over the area with a cloth or swab slightly damp to clean off the sugars and salts that are on the surfaces going over it a few times gets this done. I’ve personally stopped working on the AppleWatches but I often found this was needed. If the parts still have a lot of adhesive left I sometimes do this second. The second is to remove any traces of the old adhesive as well as any skin oils. Here I use Goof Off. This will dissolve the old adhesive but it does leave an oily residue! So now we need to clean it off either allowing it to evaporate over a few days. Or, use reagent grade isopropyl alcohol 90% or higher. The stuff you get over the counter is not clean! This is where I find many people get into trouble! The residues within it leaves a film which interferes with the adhesion. This also will remove any grease or wax as well. I often need to go over the areas a few times to make sure I get it all off. The last issue is making sure not to touch the surfaces with bare skin! use tweezers and a small metal spatula in the iFixit tool kit. Make sure you wipe them down before you use them.
