3 Special Crafts in Membrane Switch Manufacturing -- Light Color Background

 In last week, we have explained you the second special crafts in Membrane Switch Manufacturing -- Glossy Window with Matte Surface. The special process we are going to introduce today is probably the most special one, which you may never have heard of. JRPanel named it Light Color Background.

 

DEFNITION OF LIGHT COLOR BACKGROUND

 

As the name implies, the background here refers to the background of the graphic layer of the membrane switch product. So what kind of color is considered as light color? Let's take a look at this color comparison image.


 


Four colors are shown in this image: 20% Gray, 10% Gray, 5% Gray and White. In JRPanel, if the background color is lighter than 20% Gray, then it meets the definition of a light background.

 

LIGHT COLOR BACKGROUND PROCESS

 

For the light backgrounds mentioned above, JRPanel will always take a second printing. At the JRPanel factory, screen printing is done in layers, and the background color is usually printed first. During the first printing of the light background, our engineers found that the panel also had some light transmission. If the panel is mounted on an LED or LCD at this time, we will find that some of the light will penetrate the light colored panel, causing the entire panel to " shine".

 

However, JRPanel's engineers found that such problems would be effectively solved if the panel was printed again at this point. The second printing would be a more complete coating of the substrate. At this point, the entire panel is no longer translucent, although the color is still light. Since the background color is full enough, when all the colors are printed, the visual effect of the whole panel will be surprising.

 

Now JRPanel has explained all the 3 special crafts in Membrane Switch Manufacturing to you. In the future, we will continue to bring you knowledge about membrane switches in the future. Welcome to follow us!

What Exactly Is the Difference Between IP66 and IP67?

  What is IP67 and what is the difference between it and IP66?   This is probably the question that JRPanel engineers have been asked most often recently.   On the  online pricing page  of JRPanel's website, a new option appears in the Rear Adhesive section: 3M300LSE & Waterproof ( IP67 ).   In fact, this is a waterproof process recently upgraded by the JRPanel factory. This process can bring more possibilities to your products, and it also marks that JRPanel's products have reached a new level.   So what is the difference between IP67 and the previous  IP66 process ? In this article, we will explain in detail.   In the previous article  Criteria for the Classification Ratings of Ingress Protection , we introduced that the ingress protection rating is composed of two digits. The first  digit  represents the level of the electrical appliance's ability to prevent intrusion of foreign objects, and the second  digit ...

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 ...

Brief Introduction to Flat Spiral Coil Inductors

  Hi guys! Today JRPanel would like to share a few points about Flat Spiral Coil  Inductors  with you. Basically, a flat coil inductor is an inductor wound with flat copper wire.  The picture below is the side view, we can see that each circle of copper wire is arranged very compact. Here are some of the application characteristics of flat coils : 1.  High current inductance 2.  Lowest DC resistance           3.  Can ensure smooth drop of current-resistant inductance 4.  Suitable for reflow SMT process 5.  Lead-free, RoHS compliant This pciture shows a flat coil product.  It is generally used in power supplies, personal computers and other handheld  electronic devices . Advantages of  F lat  C oil  I nductors are : 1.  Scientific and reasonable space design. 2.  Tight and flat between turns ensures the effective cross-sectional area of the wire, which greatly reduces the copper loss ...
