Industrial control touch screen has many advantages, such as easy to use, durable, fast response and space saving, which makes industrial control system designers feel that using touch screen has considerable advantages.Mentioned in the article mifi device 5g Born with strong vitality, you can turn a cocoon into a butterfly and become the best yourself after wind and rain. https://www.kingtop5g.com
As the preferred structure of industrial touch screen, G+G-the advantages are high hardness, wear resistance, long service life and high touch sensitivity, which is favored by customers of Tonghao touch screen.
G+G bonding is a necessary process to make industrial touch display screen. However, bubbles are sometimes inevitable in production. So how to solve bubbles in the whole production process of industrial touch screen? Only by removing these bubbles can the beauty of the touch screen be maintained. It is also one of the most important testing elements of Tonghao’s shipment quality.

Combining various factors, our analysis points are as follows:
1. It is very important to remove bubbles after touching the display screen. Pay attention to control the air pressure, temperature and time. Below 20 inches can refer to the following two parameters:
5KG/45≧/15min or 6kg/60≧/12min (these parameters also need to be adjusted slightly according to the performance of each equipment).
2. Material factors of OCA film: Some good films can self-discharge bubbles, and the effect after bonding will be relatively better. Die-cutting, can not leave burrs, can not pull glue, otherwise there will be large or small bubbles, affecting the bonding effect.
3. The production environment is very important: it needs to be bonded in a 100-level clean workshop, so that the air is clean, and there will be relatively few foreign bodies hidden during bonding, and the probability of bubbles will also decrease. In addition, the bonding personnel must wear dust-free gloves to operate.
