Discussing methods for performing a glass only repair as a business?
So as the title says, I'm looking to start performing glass only repairs on iPhone 5S's, 5C's, Samsung's etc. There are several methods ranging from several price ranges, but for what I want to do I want a high success rate, and 0 bubbles. I want an efficient business setup (I am a business owner) to explore these cheaper repairs.
These are the two things I was looking;
The first, LOCA (Liquid Optical Clear Adhesive) Which is applied on the screen after separation and cleaning then after the removal of bubbles it is then cured under a UV lamp.
The second, OCA (Optically Clear Adhesive) which comes in pre-cut sheets that are applied to the LCD and the glass is attached.
I was originally leaning towards LOCA, and now OCA, but I have queries with the pressure methods of removing residual bubbles in the gap between the glass and the screen. There are two ways to remove bubbles, an autoclave, and a vacuum chamber. I am wondering, for anyone who has experienced, which works better for what method? Also, if the vacuum chamber is a viable option, do you think it would be possible to make your own (having the knowledge and tooling of course). Is heat necessary when removing bubbles? To my understanding it works best at roughly 60 degrees centigrade(140 degrees Fahrenheit). How do you heat the screen in a vacuum? Would any autoclave work? Or would I need to fork out the $1500 for a purpose built autoclave? What pressure is required for these bubble removals? I'm looking for the most cost effective professional method for performing glass only repairs on phones, while still having some level of automation and a high success rate? What do you guys recommend? I really appreciate any tips from guys already doing this. Thanks so much! :)
P.S. Could anyone explain exactly how each bubble removing method has an effect on each type of screen adhesive? I have heard that using an autoclave with LOCA would make it spit out the sides? The vacuum chambers make the bubbles expand and then come out the side, how long does this process take? It just seems to worsen it while looking at it. Sorry for all the questions but it's a lot to invest, especially for someone of my age (15).
Sorry if this belongs in Meta, I wasn't quite sure.
