- No bubble, but they came back couple hours later
- as recomended, put in autoclave again at 20ºC an 0.4 MPA for 20 min
- No bubble, but some little bubbles came back couple hours later
- autclave for third time and fourth time, always 20ºc and 0.4mpa for 20 min.
- stiil have a very very little bubble at the bottom left corner.
LCD 02 is a Galaxy S4
- put it in autoclave at 20ºC and 0.4 MPA for 20 minutes.
- Many bubble still remaining
- put it in autoclave at 50ºC and 0.4 MPA for 40 minutes.
- Less bubble, but still many of them
- put it in autoclave at 75ºC and 0.4 MPA for 40 minutes.
- Almost no bubble and some came back couple hours
- as recomended, put in autoclave again at 20ºC an 0.4 MPA
- Just one medium bubble, but some others came back couple hours later
So. As i mentioned before, i am doing almost everything manually. The only machine i have is autoclave.
Do you think my problem could be on laminating? |
The problem is not Laminating I have ~6-8 months working with OCA and have tried With and Without laminating and used to have the bubble problem but only like 1 screen out of 10

The machines are not the culprit for this issue let me share my experience
(I'm using Mitsubishi OCA)
(Tried different types of adhesive removers does not really matters)
When I started working with OCA I used the autoclave a LOT since my laminating skills were bad and sometimes I had bubbles a few days after repairs like 1 out of 10 screens but don't get me wrong the laminating process was not the problem BUT since I was not laminating perfectly, that made the process inside the autoclave longer so the OCA was exposed to vacuum and heat for a longer period of time.
So I noticed when I finished the process in under 15 min
Laminating 2-4 min
Autoclave 6-10 min
The chances of bubble would be around 5%
When laminating went bad and I had to use autoclave for more than 25min
the chances of bubbles a few days after repair would be around 40%
So I figured what happens inside the autoclave causes the bubbles and I tried different things like adjusting the values for pressure and heat (I'm not an expert)
Did not really make any difference so finally my wife suggested that I put the OCA in the Fridge Before and After every repair and believe it or not guys this has solved my issue 100%
the Before part is not that important since most of you take care of your OCA by having them on the fridge at all times probably
It's the after that really hits the spot since the OCA get's out of the autoclave at around 40 degrees which is my current setting and it's weak at this point, easier to yield but the cold takes care of that really fast, I leave every screen like 10min- 1 hr after each repair and it's been enough so far, at the beginning I left them like overnight lol
So guys I hope this helps some of you having this issue If you have any questions fell free to ask
I myself have some questions about iPhone 6 repairs
