What measures can we take for bubble free lamination with Vacuum OCA laminating machine?
Vacuum OCA laminating machine is an indispensable equipment in the lamination process of mobile phone broken screens refurbishing.It can make the front glass and LCD screen completely laminated together in a seamless way.However,when using the vacuum OCA laminating machine,air bubbles may appear.What measures can we take to avoid this problem?
1. First of all,please make sure the entire process completed in a dust free environment.
2. Secondly,there is a certain relationship between the generation of bubbles and OCA glue.You are suggested to choose the reliable brands such as Mitsubishi,because in most cases air bubbles appear because of poor quality OCA glue,such as unevenness,poor viscosity and poor air permeability etc.
3. Before lamination,the 2 in 1 Aligning & lamination mold would be very helpful with aligning,but why it makes aligning easier and better than the normal or universal one?That's because it's designed with high accuracy,one mold for each phone model.And it greatly reduce the possibility of pre-lamination since the 2 in 1 mold can be put into vacuum OCA laminating machine for lamination directly(no need to take the screen out from aligning mold after aligning).
4. In the process of OCA lamination,it is a must to pay much attention to the operation method.At present,there are many manual vacuum OCA laminating machines(OCA film laminating machines) used for OCA lamination in the market,but made by way too many different manufacturers and trading companies,it is really hard to distinguish which is the one with best performance.A good vacuum OCA laminating machine should be equipped with a selected platform and the roller is adjusted to a certain height,reasonable avoidance and pressure.A smooth lamination process will bring perfect lamination,greatly improving the yield and efficiency.
5. In the vacuum lamination stage,please make sure the correct setting of parameters such as pressure,negative pressure,temperature,time,etc.All vacuum OCA laminating machines with heating function from OCAMaster set different parameters for different models and provides free technical guidance and training.
6. The last but not the least,it proves the selection of a good performance bubble remover machine is indispensable.When air bubbles found after lamination,bubble removing should be carried out at the very first time.
