The lcd separator machine is usually kept on 80 degrees. This is the best temperature for success without burning polarizers. The machine produces safe temperatures but if you walk away and leave it there I’m not so sure how safe that would be so just keep that in mind.
Looking at this machine you’re wondering how strong is the vacuum. Trust me this is very strong. I stuck it to a wall and it stayed and was extremely hard to remove. This lcd separator machine comes with an external pump. This gives it a bit more power than the machines with a built in pump would have.
I actually prefer this machine a lot more than the clamp version because so many screens nowadays are just completely shattered on the top and bottom and it has always been a problem to cut these screens. A few tricks like super gluing it to the actual hot plate, double siding it down, holding it, or just using the hot plate as a heat pad and cutting it by hand were working for the clamp version which was okay but at the same time you know something else the had to give and finally this machine has hit the market.
When comparing this vacuum lcd separator machine against a machine with clamps, this one would win. This machine seems to be a major improvement in the design of these machines. The major flaw with clamp machines is that they do not secure the screen go enough. Sometimes the screen tends to move when you are doing the repair. Also, some screen are pretty cracked, so you cannot even clamp them down. The vacuum eliminates the problem altogether. No matter how badly damaged the screen is, it will hold onto it and allow you to separate the cracked screen from the lcd assembly.
There are many different models of these machines. All have their benefits. Some have external pumps, newer ones have them built in. Whichever you choose to get, just get one of these instead of the machine that has the clamps.
