The Use of Windotex in Membrane Switch/Panel Window

 In the membrane switch industry, we often need to cut some windows of different sizes, shapes and transparency on the panel material of the membrane switch for LCD or LED display. When screen printing these windows, there are many aspects that need to be paid attention to in material selection and usage. Today JRPanel will comprehensively and systematically explain its function, performance and precautions for use with Windotex, a product of AutoType.

 

When using Autotex PET material, we can screen print a variety of different color effects on the printing surface of the sheet. At the same time, we can also screen-print windows with different finishes on the surface of the sheet according to the different requirements of users for LCD, LED or other different purposes.

 

Windotex is specially designed for Autotex PET to produce different effects of display windows, which can fully meet the requirements of users. Below we will introduce the precautions during the use of Windotex.


Autotex PET material 


1. Windotex is a liquid that is specially designed for AutoType industrial product PET and can produce different display effects on its surface. It is screen-printed onto the panel material, and then dried in a UV oven. The resulting window is wear-resistant, scratch-resistant and chemical-resistant.

 

2. There are two products of Windotex:


Windotex Gloss - Gloss is greater than 80%;

Windotex Antiglare - Gloss is between 50%-75%.


At the same time, according to the different effects required, Windotex Gloss and Windotex Antiglare can be mixed in different proportions to achieve different effects between the two. The precise gloss depends on the conditions during the screen printing and drying process.

 

3. Printing Notes

 

The AutoType sand surface material Autotex must be printed with window liquid within 48 hours after being taken out of the package. If there are multiple color inks to be printed, Windotex printing is best done as the first or second process.

 

--Engineers of JRPanel concluded based on years of production experience: After Autotex was taken out of the package and exposed to the air for more than 48 hours, its absorption rate of Windotex began to decrease. Therefore, we must re-wrap the unused panel materials in piles to extend the absorption rate of Windotex as much as possible.

--The printing workshop should avoid direct sunlight.

--The printing workshop should be kept clean and dust-free.

--Before printing, we use an antistatic cloth to wipe the surface of the materials to ensure that the cleanliness.

--Printing thickness:15-20 μm.

--Do not pour unused window liquid back into the original tank.

--Windotex should be thoroughly stirred for more than 2 minutes before use.


4. Precautions for Solidification

 

--In order to prevent dust pollution, the window liquid should be solidified immediately after printing.

--When in the UV furnace, the printed window should not be placed on an uneven or hot surface, it is best to place it on a metal plate.

--Light source energy: 120W/cm


5. Once Windotex is printed on the panel according to normal operation and properly solidified, the final product will have a long service life.

Identify Different Types of Transformer Cores, Based on Materials

  Hi guys, this is JRPanel ! In previous  blog s, we have introduced several points about High Frequency Transformer, like  bobbins  and  Flat Spiral Coil . In this blog, JRPanel would like to introduce the commonly used magnetic cores in transformers ,  based on materials.   Generally speaking, the material of the core determines the environment in which the transformer is used. A transformer that uses a core of a different material will have its performance affected, may even be non-functional.   By material, magnetic cores are generally divided into the  several  categories . JRPanel will introduce them one by one to help you understand more fully.   1. Manganese Zinc Ferrite Core Mn-Zn core is a soft magnetic core with high initial permeability (2000~15000). The higher the initial permeability, the lower the surface resistance, so it is generally used in circuits below 1 MHz. Mn-Zn core has a high saturation flux density and causes lower losses, making it one of the most desirable

The Relationship Between Plastic Nameplates and Membrane Switches

Before the 1970s, most nameplates   were made of metal materials. Today, plastic  nameplates   have been widely used in household appliances, instruments, meters, office equipment and other fields, and have become an indispensable part of electromechanical products. It not only plays the role of trademark identification, specification model, function indication, etc., but also becomes an element that reflects the appearance of the product.   With the continuous use of new materials and new processes, the surface of plastic  nameplates   is constantly improving, and it has become the crystallization of three major technologies: comprehensive surface treatment, processing and molding, and screen printing.   Plastic  nameplates   can be divided into 2 types according to their material processing methods and objects of use:   1. The injection-type plastic  nameplate   is made of ABS, PC and other engineering injection molding, and then undergoes secondary surface decoration processing such

The Main Use and Classification Methods of Transformer Bobbins

  Hi guys, this blog is still about   high frequency transformers .   JRPanel   would like to introduce you the main use of transformer bobbins and how we classify them.   In the pictures are the transformer bobbins.        Following are the main uses of that JRPanel has summarized for you:   1. The bobbins provide space for winding copper wires in transformers.   2. Wire channel in the bobbins provides path for transformer winding.   3. The bobbins help to fix the core in the transformers.   4. The metal pins in the bobbins are connected to the  PCB  after soldering, which play an important role in conducting electricity when the transformer is working.   5. The baffle at the bottom of the bobbins isolates the core from the tin stack to avoid poor volta ge resistance.       From this it can be seen that the importance of bobbins in transformer is extraordinary.   After understanding the main uses of transformer bobbins,  JRPanel  is to introduce its common classification methods.   Fi
