Glue is losing grip after LCD repair

Hello everybody.

I've got a small repair shop in Germany and most of the time I fix iPhones and Samsungs.

But lately a lot of customers show up with Sony Xperia Z3's with broken Glass and / or Touchscreen / Digitizer.

To change a LCD-Unit or a Digitizer isn't a problem for me.

I order a brand-new LCD-Unit or Digitizer along with the adhesive tape (already cut out in the right dimensions) off a wholesaler, clean the frame with 99% alcohol and Q-tips or microfibre cloth and install the new screen onto the frame.

And here is the Problem:

The adhesive tape is getting loose after a few days.

Especially on one of the corners at the top of the device.

I never experienced this issue on Samsung LCDs or any other devices except Sony Xperia devices.

I tried to solve this problem by using adhesive tape off a roll (3M) instead using the cut out adhesive tape, but the problem is still appearing from time to time.

Did somebody of you had same issues with this stupid adhesive tapes (cut out or not) and found a way to glue the glass to the frame of Xperia devices?

Like is there some kind of adhesive that is strong enough to hold the glass and frame together?

Thank you very much in advance!

Sorry for my bad english :(

I have exact the same problem too..

I've had my screen fixed and the new screen has never sat on phone properly! The light shines through the sides. So annoying as it cost $250 to repair and I've now got a dodgy phone with a screen that doesn’t work properly and I would have rathered bought a cheaper brand new phone! Fed up!

Please use B8000 adhesive.Best solution ever

by

Hello, do you know the difference between B7000 and B8000 ? i dont found informations.

I repair many Sony mobile , and the stickers unstickers very often! and with the B7000 its not very better :-/

My sollution is two stickers! first on the frame, and the second on the screen Maybe that more thickness = more flexibility on the twists and better adhesion between the two stickers.

I had this problem all the time, usually down to the frame not being cleaned properly. Make sure you're using the original waterproof (supposedly) adhesive. Get some micro-clamps and clamp it down in each corner but do NOT clamp anywhere that is near the screen. I learned the hard way and did damage to a Z2 lcd, it wasn't big damage but you could see the pressure from the clamps.

So, just clean the frame with IPA or whatever you use and clean the LCD and then make sure you properly apply the adhesive without creases etc.

I personally hate working with Xperia's. I have one of my own that I've had for ages because either the LCD will come apart or the back glass will come apart, very easy to repair but so annoying to get right.

Hope this helps

would you use an adhesive like the E6000 for a job for your xperia?

by

The risk of liquid glue like E6000 is, that it can run between the LCD and damage the whole screen...

by

Actually you can test E6000 on the broken screen, to see if it really gets in between the LCD, also with a new original screen there is thermal adhesive tape on the back of the LCD and tape going from there to the front glas. Maybe this can prevend glue getting in between the lcd and backlight part. I tried it with E6000 glue, did not get in between backlight and lcd (because the viscocity was less of the glue compared to new E6000 glue). But did get out of the frame and front glass. After 24 hours when the glue is really dry, then I tried to remove, but the glue is so flexible, that I teared out all the glue from the 2mm bezzel. So I am looking for a new glue to hold it down. Never use superglue for this job.

original LCD for Z3 and z3 compact is thinner than china LCD thats why it can't be "normally" mounted in original frame. Digitizer must be glued to frame in middle frame also. IN the beginning, also sony realized if they will use only glue tape for z3 frame it will not hold like in z/z1/z2 model so they decide to use some kind of silicone glue and glue this digiitzer to frame with this glue not with tape. we must find what kind of glue sony used for frame or you can buy lcd+digi in frame which will be also glued by china workers.

Sony for Z3 lcd made black thin protection foil to prevent glue to run into LCD.

I start post about it in XDA forum, Z3 Q&A maybe somebody will show some light on it.

I've had success using clear cell phone tape.

pre-apply the tape so that that it overhangs the edge of the lcd glass, use a VERY sharp exacto blade to trim off the excess. takes patience but provides a good, tight, sticky finish.

thanks for reading.

I run a small repair business and have also had problems with Z3 (and occasionally Z3 compact) coming unstuck. I think I may have now cracked it :)

I first clear all old adhesive, clean both the frame and the new screen with 99.9% isopropanol and microfibre cloth, I allow to dry then apply TWO layers of the best quality 'original' adhesive cutout I can find to purchase. I add a small amount of silicone glue to the top and bottom of frame and secure the screen in place. I apply a small amount of heat and use little plastic clamps for a couple of hours on top and bottom of screen. This seems to have turned the nightmare of Z3 into a minor headache :)

For the Z3's I've always used what we generally refer to as 'red tape'. It's a strong-bonding clear double stick adhesive. There WILL BE LIGHT LEAKING FROM THE EDGES. It's simply because the original adhesive (glue) pulls the screen down more tightly and it's opaque. The clear adhesive isn't, but it holds very well. The same thing is common with the LG G series phones. I get all of my red tape from Etechparts.com. Use a little heat after (I use 65C for 15 mins on my heat plate) to help the adhesive bond to all of the surfaces correctly and clamp it tight while the adhesive cools.

For the Galaxy S5's and especially the Note 4's (which are notorious for coming loose) you have to get high quality adhesive. The stuff on Ebay won't cut it. I've gone to Etradesupply.com for all of my Samsung adhesive needs. I've even tested their S5 adhesives with the water test. They retain the water resistance as long as the frame isn't tweaked. Again, 65C for 15 mins on the hot plate after, clamp and let cool.

I've noticed the largest difference between a screen staying or lifting on me a few days later is the heat. When the adhesive heats, it gets pressed outward, applying to the whole surface. Then clamps for cooling! If you don't, the heat will just loosen it. If you clamp it, it spreads the adhesive out further, and the cooling contracts it, sucking the screen down to the frame. Great method for iPads too!

Alexander, I don't have any experience with repairing Sony Xperia screens. I have done a few Samsung Galaxy S5 and Note 4's. I'm not a pro by any means...I just do it for friends and family. Would you mind sharing how you're able to get the Samsung screens to stick to the housing? The pre-cut adhesive tapes I bought from ebay are not as strong as the original ones. Not even sure if anyone sells the original ones. Thank you!

If you repair Samsung Displays, you probably are using LOCA-Glue in combination with an UV-Light for bonding LCD and new glass.

After you apply the liquid LOCA-Glue, put a bottle of water (~1 kg / ~2 lb) on top of the new Glass for a couple minutes before you put the whole unit under UV-Light.

The weight of the bottle will squeeze out some of the glue, leaving a thinner layer of glue. This way the whole Display-Unit (LCD with new glass) will be thinner and fit better into the housing of any Samsung Galaxy.

A thinner Display-Unit which fits better in the housing of the Galaxy will ensure a better contact between the outter glass and the frame of the Samsung, because the gap between glass and frame is smaller now.

This again ensures a better contact between your pre-cut adhesive tape on your device.

Clean up the frame with alcohol or nail polish remover and don't touch the back side of the glass or the frame with your fingers after you cleaned it.

I hope this helps you ;)

Actually, I just buy a complete screen/AMOLED assembly. The hard part for me is to secure the assembly on the housing. The previous cut double sided tape I bought in ebay specific to the phone model doesn't have enough strong adhesive to keep the screen assembly on the phone housing.

someone told that used 2 adhesive tapes,

does it help? anyone else tried? it seems that it will be a thicker adhesive band, and the screen won't be pushed anymore by the stainless steel plate

probably will try it on next repair
