Glass-Only Repairs: Part 2

Glass only repairs are quickly increasing in popularity as technicians search for a more economical way to replace the glass on a smartphone. Since designers of consumer electronics are continuing on the path of the small, smaller, and smallest, more devices will be held together with gobs of sticky adhesive. As LCD glass assemblies rise in cost, and thus create narrower margins for business owners, glass only repairs could easily become an important aspect of the electronic repair industry.

Thanks to members of our Repair Community on Facebook, as well as countless repair technicians and our vendors, we’ve learned a lot about these repairs. We’ve also researched the tools that work – and don’t work – so we can offer as many options and as much information to our community as possible. Stay tuned during the coming weeks, as we will have more information to offer on how to do the repair.


NEW! Polarizer Film

Polarizer film is a thin piece of film that goes between the LCD and glass during re-installation. Simply put, polarizer film helps reduce the reflection of light off the glass and LCD after installation. Similar to the lens of polarized sunglasses, this piece of film does the same job of reducing reflected light and UV rays. eTech Parts is happy to announce we now carry polarized film for the most common glass-only repairs.

Note: Make sure to remove the protective film on both sides of the polarizer film prior to installation.


LOCA and Translucent LOCA Alignment Mold

As previously mentioned on the eTech Parts blog, we are loco for LOCA, or Liquid Optical Clear Adhesive, which is the glue that goes between the LCD and glass during a glass-only repair. This glue is the best to use because preventing bubbles is easier with LOCA than with the pre-cut sheets of optical clear adhesive.

Now eTech Parts has a new tool to make applying LOCA even easier! Introducing the Translucent LOCA Alignment Mold for iPhone 5/5s, this professional tool is specially designed to align the LCD and glass lens during installation. This tool makes it easier than ever to properly apply LOCA for a perfect install, every time.

Last but definitely not least; you will need the glass for these repairs! eTech Parts offers each piece of glass necessary to complete these repairs – including Glass Only for iPhone 5, Glass Only for Samsung Galaxy Note 2, Glass Only for Samsung Galaxy S3 and Glass Only for Samsung Galaxy S4.

Offering this repair is an investment and with the proper tools, knowledge and ambition this repair will not only increase your profits but save your customers money as well. As mentioned in eTech Parts‘ previous Glass-Only Repairs article, we highly suggest practicing this repair on an extra or non-working LCD/Digitizer assembly before attempting on a customer’s phone.

What happens if you recycle a LCD, where you separate the polarizer without attaching a new one on it, and bonding the lcd with a new glass. I've done this in my shop a few times.

If you take the polarizer off an lcd you won't be able to see anything on the screen. So you need to put a new one no doubt about it. Besides every time you replace the glass on an iPhone 5, 5c or 5s you have to replace the polarizer if you intend to use oca which is the appropriate methodology for iPhone 5 series as the polarizer is underneath the glass, meaning you will scratch the plastic cover of the polarizer, creating scratch marks on. The right equipment and knowledge is important and is required to do this job correctly. Although a lot of good techs are doing them with LOCA, it does not mean is the right method to use with iPhones.

Thanks for posting that video, Luis! We agree with you in that the right equipment and knowledge is required for proper glass-only repairs...and a lot of practice, too :)

This is the way I replace the polarizer.

Guys, if you remove the plastic film under the oca on top of the polarizer, you will most likely damage the conductive paste on the top of the lcd, which will give you a static ghosting effect problem. Also if you remove the polarizer. So replace the polarizer and add the silver conductive paste in between the small area on the top part of the lcd.
