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.
Ist dies eine gute Frage?

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.
War diese Antwort hilfreich?
Cheers for that but yep apart from the distilled water tried all that the screen I used to replace was brand new so no dirt on that but still gave it a wipe used 99% isopropyl alcohol to clean before I applied new adhesive strip with tweezers & pressed down with a spudger tip to adhere to watch frame first. Used tweezers to remove top adhesive protection & then pressed screen down evenly. I always make sure I don’t touch any of it with my fingers as I know about leaving grease or sweat so I always use rubber surgical gloves whenever I work on any device. I’ll give it a go with the distilled water & try again. Thank you
