Recently i got some feedback from customer like Peter, Wesley, they asked me to keep writing some contents here to help people who has not much experience of LCD repairing.
Well, thanks for your guys suggestion, i am Alex from OCAmaster China factory, i am the CEO and also a technicial guy with about 5 years experiences of LCD repairing industry, my english is not so good so i can only write some simple sentence, but i hope it can help you to learn some useful points from my content.
Today i want to talk about how important of the vacuum condition for a LCD laminator machine, as you know, the full name of OCA lamination machine is "Vacuum oca lamination machine", so Vacuum is the precondition for LCD laminating.
1, How to get vacuum ?
OCAmaster has 2 kind of machines, they are all in one model & separated model, all in one model means the laminator, vacuum pump, air compressor, bubble remover all built in one machine (such as K5, K5i, K5EDGE, K6EDGE), those machines are very popular for a individual repair shop since it won't take too much space from your table. some people said the all in one machine is not good because if any components damaged, fixing it will be a problem.
i don't know how is other factories made their machines, but from ocamaster, all machine's components are very organized, all wires has been marked which is easily for replacing new parts if anyproblem happen. like below photos.
Separated laminator is only for lamination, you need to connect it with an extra vacuum pump, air compressor, and you need a bubble remover for bubble removing, this kind of machine normally is suitable for mass producing (LCD repairing center, over 500pcs per day), OM-K4 & OM-K4Plus is a fast lamination for mass producing.
All the vacuum motor for the machine above can pump to over 99.5% vacuum, this is very enough for LCD lamination, we sold more than 9000pcs machine in the last 3 years and never had customer complain about our vacuum motor can't pump enough vacuum.
2. Select a good connector for machine.
OCAmaster's new machine has upgraded to the metal self-locking hose connector, many factories does not choose this kind of connector because it consume more time to assemble machines compared with the fast hose connect, but ocamaster prefer to consume more times for getting a better performance.
3. Equipped with a digital vacuum monitor & controller
Digital vacuum monitor's accuracy is 0.1Kpa, OCAmaster's machines all equipped with this digital vacuum monitor and it made our machines are high sensitivity control vacuum motor's working, MOST OF OUR COMPETITORS'S MACHINE EQUIPPED WITH POINTER TYPE MONITOR, pointer monitor only can show the vacuum but can't control vacuum motor starting and stopping.
Once vacuum degree is enough, bubbles will be easily removed after put in the bubble remover, a good laminator need a good vacuum motor, OCAmaster do understand about this !
