How can I prevent Loca glue from entering the side of the LCD (backlight) screen? I got the whole glass replacement down and the screen working, but theres is a slight discoloration in the corner of the screen, just wondering what would be the best technique to prevent the local glue from entering the backlight in future repairs. Thank you in advance for your answers.
Loca glue is messy unless your buying them in sheet form then applied by machine…if you don’t want glue in the backlight just remove it off the back before glueing but keep in mind it is vey delicate and in some cases people just resolder a new one.i used to do refurbishing and if you have the machines and you know the proper way to fix with no esd or particles then you can make some money.
The best and somehow easy way to prevent the glue would be by taking the backlight film off gently, putting a thin transparent tape on the mirror of the lcd and then applying the glue. When the glue dries using UV, take of the tape clean the mirror with isopropyl and put the backlight film back carefully. Voila, no marks and u got a clean glass replacement. Please note, that to take off the backlight you will need to unsolder the three small connections first and when putting back the backlight you have to resolder them back. Not very difficult to do so, so you can give a try. And please also note, when glue goes in between the lcd you don’t have to throw it away. Just remove the backlight film and clean the mirror with isopropyl or acetone. Film costs like 5$. Just be gentle and have patience.
you may laugh at this but seriously stopped any glue spots on lcd what I did was use blue tac around edge of lcd before aligning the glass it’s worked on every glass repair I’ve ever done and the only awkward thing I found was cutting precise sizes but roll it into a rectangle shape then use a Stanley blade to cut to size honestly try this easy to remove afterwards to ;)
Hey dude.. Just try this tips. Make sense and also its easy to do. Prepare oca tape. (i use 5.5 inch oca tape sheet) and you can adjust the length depend what your need. Use oca tape as sealent. cut oca tape to divided 2mm or 3mm wide (and it will be very much). Then stick on each side of lcd (side, up and bottom). It will be hold LOCA to leak on the lcd backlight.
The machines you need to use OCA (a sheet of adhesive) would set you back a few thousand not to mention you will need a HUGE amount of space to set it up and even know you won’t sail through the process. The easiest way is to completely remove the backlight and replace it with a brand new one LOCA will always get through unless you remove ALL uncured loca. you would be surprised how much there is that you can’t see/have access to
The best way to give a good quality is using OCA instead of LOCA- but that method is gonna b expensive- coz you need autoclave vacum machin to get rid of bubbles. So the second best way is as younis said take the back light off- but you need to make sure you are working in dust free workplace. Or try sugru on the sides of lcd to prevent LOCA between LCD and BACKLIGHT- If you are very good in alignment of GLASS and LCD- coz you can not use mouldy if you use sugru
LCD never catch loca. I think it’s dirt or something else.
