Compared with black, white mobile phones are more popular with consumers, but white products are more difficult to process.
however, with more and more new materials.

White OGS ink and the characteristics of the ink manufacturers

new technologies and manufacturers' accumulated experience, the yield rate of white products has been greatly improved, and white OGS will be more and more used in mobile phones, mid and other terminal products.
in this paper, the author analyzes the advantages and disadvantages of white OGS8 h" X$ V3 P5 e' V* a(U: Q9 @ 2 p * q "\ \ white OGS products.
at present, the mainstream process is still realized by screen printing high temperature resistant white ink and coating after curing.
due to the different design schemes of various manufacturers,
the process routes will be quite different.

its temperature resistance.
the curing agent should be added when usingHowever, the curing agent must be added before using the ink.
and the addition of the curing agent will affect the life of the ink and the consistency of the product screen printing. Therefore, the application of OGS, which requires high surface smoothness, is limited to some extent, and the screen is prone to dry screen blocking, As a result, the waste of ink and screen printing will be caused, and the production efficiency will also be greatly affected.
in this paper, the author analyzes the reasons for the waste of ink and screen printing* R1 `; O* I( {; }1 W% G$ O8 D9 U+ The second type is one component modified type.
no need to add any curing agent or catalyst before use.
excellent high temperature resistance makes the product no yellowing problem.
it also overcomes some disadvantages brought by two-component ink.
at present, some mainstream OGS manufacturers use this type of ink.
through the simple design of screen printing graphics and the improvement of coating process.
at present, the steps are climbing Moreover, there is no difference in the square resistance between the ink area and the window area.
the results show that the square resistance between the ink area and the window area is almost the same. _ " h* ]/ b.
