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!

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 ...

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 transf...

How Does JRPanel Assemble Your Membrane Switches

Let's talk about the assembly of membrane switches. 1. Installing LED and baking For products that require LEDs, JRPanel engineers will attach the LEDs to the corresponding circuits. The printed circuits are subsequently put into the oven for baking. 2. Cutting Cable Engineers will cut out the cables in bulk with a cutting die or laser cutting. 3. Installing Male Pin Before installing the Male Pin, the end of the Cable must be cut flat. Next, the Cable is placed under the machine and by pressure, the Male Pin is positioned and fixed at the end of the Cable. This step is to ensure the conductivity of the product. 4. Silver Paste Die-pressing Silver paste die-pressing is a heat embossing process on the circuit layer with a die. At JRPanel, the dies used for this process are all aluminum plates. Therefore, compared to metal domes, the die-pressing process results in the long service life of the keys. 5. ...
