Which LCD Screen Repair Separator Machine is Better?

Now the market have two main LCD Screen Repair Separator Machine, te yellow one and black one as below:
What are the diffierences between them? Which lcd separator is suitable for you?

First:  The temperature controller is different, the black one uses industrial,  which is widely used in BGA rework stations, because it can bring high accurate and precise temperature detection.

Second:  the black LCD Screen Repair Separator Machine uses sheet metal, which can experience high temperature higher then 300 degree. But the yellow one uses bakelite（Phenolic Resin,)  once the temperature get to 150 degrees, the material will give off  toxic gases which is bad for your health .

Third:The black lcd repair machine is 2 in one . It is not only ideal for separator the cell phone LCDS,  but also can be used for bga reballing & soldering like reflow oven ht-1212, because the temperature can get to 200 degrees, but the yellow one can only get to less then 150 degrees, only can repair cell phone lcds.

Characteristics Of Polarizing Film

Because LCD display not light, ISO identification requirement in order to display

bright, polarizing film must have a clear, high permeability and high optical

activity. LCD recently becoming more widely used, such as livelihood, military and

high-tech, particularly application of intelligent machines. Due to the diversity of

the LCD and the durability of promotion, we must strengthen the durability and

resistance to rotation of the polarized film.

In addition, the appearance of characters on, with the draw cable LCD improving

polarizing film surfaces must be smooth and fine, if prolonged use at high

temperature and high humidity environment, must also be maintained on the optical

performance, and with one of the key parts of the security requirements for

adhesives, usually in a polarizing film manufacturing process, is carried out in

clean room:
1. is PVA polarizing film footage and TAC, so it is not available on the foreign body and resin that is not soluble.
2. in the polarizing film laminating process, not glue, lamination and when there is any foreign body into.
3. the protection film and release film and other materials may not have any defects.
4. finished surface and cutting surfaces, or on the wrapper should not be mixed with any foreign objects attached to it.

If the above conditions cannot be met, you cannot make a high resolution and large

size, high precision of polarizing film.
