How to glue plastic - General Questions and Answers

Hey, this seems like quite a noob question but I broke my case, its plastic and I want to know if I can glue it back together, I can't buy a new one as they are very hard to find for my phone in my country. Can anyone give me some tips on how to glue it, what glue ect.

Methy lEthyl Ketone (MEK) will bond some plastics. Look for an adhesive containing that. When I work on swamp coolers, this is the main chemical in the bonding agents. That could work, but I don't know what kind of plastic is in phone cases. I AM NOT RESPONSIBLE FOR ANY DAMAGE YOU MAY CAUSE TO YOUR PHONE. http://www.google.com/url?sa=t&rct=...kbCrU7S0ixuXDgNCg&sig2=RKxdYs_f8e0B_MyT25yseQ Here's a wikipedia link. Good Luck!

Good video for Inspire 4G screen replacement?

Has anyone seen a good take apart/repair guide for the Inspire4G. Just got digitizer replacement and cannot for the life of me figure out how to attach the ribbon cable without totally disassembling the phone. Hoping to avoid this.
If this is the wrong forum, please direct me to a better one rather than flaming me.
Thanks
Fairly certain that ifixit.com has a good teardown.

Thanks for the tip, but I find nothing for the DesireHD/Inspire4G there other than a total disassemble for the HD that I've already seen, but really did not help me. I just need to change to touch screen. I appreciate the try though.
Got it apart. And kinda back together. Apparently it is not a good idea to reuse the double sided tape that holds the LCD to the motherboard and the digitizer to the LCD. At least the phone works. Now, must order some proper adhesive tape and redo the whole thing.... Took me about 6 hours for whole breakdown and rebuild. Doesn't really seem to fit back together all that well though. Maybe I'll videotape my next breakdown.
Couple of questions as my phone is in need of a new digitizer too.
Did you have any other adhesive tapes in the process?
What did you use to cut the tape that held the LCD together after you baked it?
Does the phone mostly feel the same now that you have it back together, or does it feel flimsy now?
I'm disappointed that it's this difficult to replace the digitizer.

Just so you know, I was a TOTAL noob in phone deconstruction. That being said, the old adhesive seemed quite sticky after i took it apart so I just reused it. Mistake number one. Once it was back together, i notice it slowly opening up like an accordion. The tape wasn't holding and the LCD, digitizer assembly started to rise up. I have since ordered some adhesive tape from the place I got the digitizer from. Definitely get the tape.
I did not bake it as in the video (i assume you watched the same one I did). I used an old spark plug gauge tool thingie to just cut through the tape. It was still really sticky so after i struggled to insert the digitizer ribbon cable, I just reused it. Don't do this. Get new tape.
I did have some plain old scotch double sided tape. I used it in one spot. Lesson: Don't use this stuff. Get new tape.
Did I mention that I think you should get new tape? All in all, it was quite laborious. I went really slowly so as not to brick it. When it was done the phone worked, but like I said the LCD raised up after a couple of minutes. The adhesive was not working anymore. At least I have gained confidence for the next take-apart. I can't believe i GOTTA go alll the way back to total break down. Aaaarrrgh.
So something like this should do the trick?

Thanks for the heads up... Where exactly do you recommend putting the tape? Does it just go on the black edges of the digitizer, or does it actually go on the surface of the LCD? Sorry if that's a noob question, but I haven't gotten the glass off and I want to make sure I have enough adhesive tape from the Ebay Vendor. Did you have any issues with reusing the mylar?
Sorry for the 1000 questions, I really don't want to shell out off contract prices for another phone...
Mylars were all reusable if removed carefully. I photographed every step so I would know what to put back where. Still waiting for my tape from Repairs Universe. The biggest two culprits are:
1] Tape holding back of LCD to the silver chassis frame and
2] Tape holding SIM FPC to the main board.
You might also tape the PCB cover to the upper board, mine was loose after rebuild.
That I believe that is it for the major tape requirements. Of course the digitizer needs to be taped to the LCD. I'm curious, though, the tape framing the LCD holding the digitizer seemed to have some thickness to it. Almost like foam rubber, quite thin, but thicker than regular cellophane tape.
Good luck. Let me know if you have any tips after your attempt.
Got the tape. Retried to rebuild with new OEM tape. Same result. The phone when completed expands like an accordion. The digitizer/LCD assembly does not stay stick to whatever is under it. I know when to admit defeat. Looks like I'm shelling out 500 for another phone. At least I have spare parts!
yeah i was going to do my screen myself till i seen the tear down & then called afew places around here that does screen replacements and said NO we won't touch the Inspire, i spent the money and let HTC fix it. was worth it they replaced the whole shell not just the screen ... IE lcd / digitizer / Outer case that was scratched and dented... basically a new phone with the guts out of my phone
I attempted to do this and let me just say that I too now have spare parts. I purchased a phone off of ebay. I didn't realize the no contract price went up to around 500.00 I should have gone directly to HTC. Live and learn...
I will be in possession of an HTC Inspire for testing purposes that also has a cracked screen. Not sure how bad it is but I was planning on just replacing the display for learning purposes. However it seems that it may not be worth the time spent.
If I do decide to give it a go I'll post my results here. First thing is to acquire new tape. Did you all purchase it locally or did you buy the adhesive online?
YouTube has lots of videos. Best to watch a few a see the best way. If you are scared to break it best you send it in for repair instead. Get a digitizer and screen combo.

Ballistics SG Question

Got this case a few days ago and have a couple questions.
1) Do you guys find this case very hard to get off? I feel like I don't want to push hard because it will do damage to the phone. Any tips on removing?
2) Do you find you have to "pull up" on the ballistic corners once you install the case to get everything even? I find that the silicone lays flat in the plastic casing without the phone in it, but once installed I have to work the corners to get the case flat.
Yea I would suggest prying from the side that has no buttons and also yea it is a very snugg fit so u kind have to work it to get the plastic price set into the rubber
I have taken mine off many times with no damage so u should be ok and it all sounds normal to me
Sent from my HTC One X using xda premium
Ok, sounds good. I love the case, just don't want to damage my phone lol. Can't imagine how the Commuter is to take off considering people say that's even harder to remove.
I kind of use my fingernails and pry off the plastic part first by sticking my fingernails in between one of the parts on the side and then using the top/bottom portion for leverage. At first I thought it was gonna damage the phone but nothing has happened yet

Painting the plastic parts and polishing The Aliminium unibody

Hello everyone , i'm relly intersted by polishing my sensation case , and painting the plastic parts in a white color , i Know that there are some antennas in the Plastic parts . I will Not sand this plastics , I'm just gonna Paint it . I want to ask you guys if it is possible to do this work . Thanks a lot and sorry for my bad english .
You can do with this plastic anything you want. Painting them wouldn't affect signal.
the 'soft touch' coating on the plastic parts wiil be hard to paint over. I don't think paint wil stick to it at all. I guess removing the soft touch finish will damage the antennas (just a guess).
You are righy, if he wants to remowe this layer he probably damage antens, but i think paint will stick perfectly if surface will by mated.
There's some cool covers here http://forum.xda-developers.com/showthread.php?t=1184568

As I think Radolex is suggesting above, you could try very gently sanding the surface of the plastic to provide a 'key' for the paint to stick to, but I honestly don't think this will work due to the properties of soft touch paint, which naturally shrugs stuff off and tries to self heal (so to speak). If you want to try it, degrease the soft touch paint, sand lightly with something like 800 grit wet and dry paper, then apply a thin layer of primer (I wouldn't know what to suggest, maybe a plastic primer or some etch primer), then your top coat. Wear a mask if you're spraying dude : )
Have a look at this site, I think it's the same kind of stuff that's on the plastic panels on the back of our phone http://www.alsacorp.com/products/softtouch/softtouch.htm
Ouzo, you should be a Safety Officer. Suggesting to wear a mask for painting. Great stuff.

LOL, I know - it's easy to overlook these things when you just want to get on with something though, or you don't understand the long term risks. I painted an entire motorcycle in my kitchen about 20 years ago without wearing a mask for most of it. It was a really really dumb thing to do....

Tips for Digitizer Screen Replacement?

http://www.amazon.com/gp/aw/d/B00AHTFNEM
This is the one I bought, for a reference. I'm just curious if anyone else has done it and what problems they ran into. I'm no stranger to electronics, so I'm not afraid to take it apart, I'm just worried that I'm going to end up doing something wrong.
For example, the glass and digitizer are fused together, right?
And do you go around the front or the sides with the heat gun? 750w or 1300w?
Here's a good DIY video:
https://www.youtube.com/watch?v=_70-W9JjVjg&feature=youtube_gdata_player
A hair dryer should suffice so I don't think you need such a powerful heat gun.

I posted this thread a few days ago after replacing the digitizer myself. The video referred to by another member was for a phone, and personally I doubt a hairdryer would suffice for the job 'cause cell phones usually use light double-sided tape to hold the almost weightless glass. The tape on the Tab 2, on the other hand, is quite strong. You can use sheer force except there's no gap at the edge, front or back, and you might damage the LCD display in the process. I used a dryer for a few minutes and it did nothing to loosen the adhesive. Good luck.
That is an awesome tutorial. You're right about it giving confidence, as well as answering many of the questions I had. I guess I'm more concerned now over just various tips and tricks.
Is there any fine science to lining it up? How easily can it be fingerprinted and what would you use? Also, I've heard of WD-40 to remove the glue left over. What should I use if this one doesn't include any adhesive?
As you can see, I'm clearly a worrier. Got it honest.

Lining it up is a no-brainer since the glass fits snugly into the frame. The lcd is a non-issue since it is separated from the touchscreen. As far as finger prints,I use a 50/50 white vinegar/water solution. Be sure to wipe it off with a microfiber cloth while it's still wet. For left-over glue,I use either Goo-gone and 91% alcohol afterwards, or acetone. WD40 is fine though I am not sure it would not leave any residue after drying out. In case the new one has no adhesive, the better choice would be the outdoor double-sided tape for 5 lbs at Home Depot, or failing that, loctite outdoor epoxy though this one could get messy.

[Q] Digitizer replacement - glue replacement?

Hi all, I got an i9300, it has the digitizer broken and I need to replace it.
The problem is, here, in Venezuela, the UV glue and the UV lamps are too much expensive... due a pathetic government.
Anyways I need to fix the phone, and for that, I need to replace the digitizer but without the UV glue and UV lamps...
I know there is the double-sided tape but it leave a space between LCD and digitizer, so I don't like it, and... the tape is too expensive also.
I'm trying to find a cheap glue replacement, but I don't know if what I've found untill now would work or destroy my LCD...
So far, I've found a transparent glue, which has the following components:
1) Polyvinyl acetate.
2) Alcohols.
3) Special solvents.
It also says that it has no water.
The thing is that I don't know if this glue would be too abrasive with the LCD and may damage it in some way.
AFAIK, the LCDs has polyvinyl acetate on its components... but as I said, I don't know how this would react with the glue...
Somebody here can give me a hint? should I try it?...
When the glue I've found gets dry, just gets cristallized and over 60ºC it can be easyly removed.
I wouldnt mess with and unknown glue or adhesive that is not meant for this type o job. I would seriously recommend considering the double sided tape. Its a perfect fit and works perfectly.

I see, well finally, I've ruined the digitizer behind the pieces of glass... and the LCD with it, so, I must buy a new whole screen.
Warning: Do the replacement with extremely patience... do not pass the 200ºC and be extremely carefully.
