What is the reason why the defrosting machine is not clean?

Colleagues who have done mobile phone screen maintenance know that in addition to the bubble is an essential part of the mobile phone screen replacement screen, and the bubble machine is one of the three essential parts (separator, laminator, debubble machine).

The mobile phone needs 4 steps to replace the outer screen: separation, removal of glue, bonding, and removal of bubbles. Defrosting is the last link, but also a very important link, if the front mobile phone screen separation and fit everything is very, but it is our turn to defrosting the mobile phone screen, if the screen is not clean, there are still bubbles, even small bubbles, then everything we have done before will be wasted, and we have to face rework, and we have to start from scratch, we all know that, Rework faces the risk of breaking the screen and leaking liquid if not careful. In that case, it will not be worth the loss, and a profitable business will lose money. So, what is the reason why the debubbling machine is not clean?

One: The quality of the external screen glass cover plate is not good or not cleaned when it is fitted.

If the external screen glass cover is not wiped clean when the fit degree will also lead to residual bubbles inside, it is recommended that we must have good quality glass when selecting the external screen glass, try to use the original glass, even if the original glass can not be bought, it should also try to buy good glass, because now the competition for mobile phone glass is very fierce, glass cover manufacturers in order to reduce costs, Quality must be sacrificed, so the quality of the glass produced is also uneven.

Two: Choose OCA optical adhesive with reliable quality

In addition to the glass cover plate, OCA optical glue is also very important, early because we do not have the ability to produce OCA optical glue, most of the use of imported glue, and Japanese glue accounted for the vast majority, there are Mitsubishi glue, there are Hitachi glue. Among them, Mitsubishi's OCA glue is used, which of course means that there is no bubble and it is good to stick. Until now, the technology and materials are also very mature, and the glue made by many domestic OCA glue manufacturers is also very good to use, if we buy a large glue and we use the appropriate thickness of the glue, I believe that the screen bubbles posted are also very few, and it is easy to remove the bubbles with a defroster.

Three: When fitting the glass cover plate, the technology is not good.

Do the mobile phone screen cover laminating is a technical work, the manual requirements are relatively high, including the glue and the glass cover should be skilled, need to be done in one go, if there are too many bubbles in this link, later with the defrosting machine defrosting is difficult to remove clean, there will be bubbles residual. This link only more paste more practice, the so-called practice makes perfect, paste to a certain extent believe that it will be able to do well.

Four: The defrosting machine must be selected well.

Good debubbling machine can be stored to debubbling required enough pressure, if the pressure can not reach, it will remove the bubble is not clean, debubbling machine manufactured by Shandong Tianyuan Machinery, debubbling effect is good, the use of tail heating and forced circulation, to ensure the working effect, and can save energy; High degree of automation, all control system using touch screen +PLC control, one-click operation; According to different defoaming requirements, can be freely set, setting flexible; Reasonable design, complete specifications, can meet your actual production needs.
