Precautions for Pasting and Storage of Membrane Switch

To use a membrane switch, we must know the using steps, so that the membrane switch would not be damaged. The way of use determines the service life of the membrane switch to a certain extent. The precautions for pasting and storage of membrane switches and membranes are described as follows:

1.Pasting Steps:

1) Cleaning: Clean the liner, casing or pasting position (the surface to be pasted is required to be smooth, rust-free, oil-free, and dust-free).

2) Check the size: Put the membrane switch (before peeling off) to the place to be pasted to compare whether it is qualified;

3) Alignment: Peel off the adhesive on the back of the membrane switch about 10mm from the side (better on no-button area ), and then paste it to the corresponding position. Check the position of the entire switch and then continue to paste;

4) Pasting: peeling and pasting (the curvature of the membrane switch surface shall not be greater than 15°);

2. Precautions for  Pasting:

1) Pasting cannot be repeated, it must be done at one time, otherwise it may affect the performance of the adhesive;

2) The curvature of the membrane switch should not be greater than 15°. The operating buttons must be placed flat and then pressed. Do not operate when there is no liner or the buttons are suspended, otherwise it will affect the performance of the metal dome and severely may cause a short circuit.

3. Precautions for Storage:

1) The front and back of the product are generally covered with transparent film to protect the surface of the product or the display window from scratches. The protective film should be kept;

2) After taking out a few of them from the original package, the rest should be tied as before, but not too tightly;

3) Products with tactile feel need to be packed upright to prevent the buttons from weakening the tactile feel due to long-term pressing;

4) The cable and connector of the membrane switch should be well protected and not placed downward;

5) Products with windows or products with tactile feel should be protected from bending by force, the performance will be affected. Severely, it may cause short circuits and dome rebound failure, leading to a switch scrap.

6) The membrane switch is stored in a room at normal temperature and should be protected from dust and moisture, with no acid, alkaline or other corrosive gas in the surrounding air.

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 Difference Between PVC, PC and PET in Membrane Switch Applications

  In membrane switch fileds, there are 3 main materials being used in production, PVC, PC and PET. To help you choose the proper material for your product, we would like to introduce you the difference between PVC, PC and PET in membrane switch applications.   1. PVC    PVC  is also called polyvinyl chloride membrane, the full name is Polyvinylchlorid membrane. The top layer of this structure is lacquer, the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. The price of PVC membrane is low, and it has excellent chemical resistance and insulation function. It is used in sign panels, but not suitable for membrane switches and light touch panels. The global usage of PVC membrane ranks second among various synthetic materials.   2. PC    PC is also called polycarbonate membrane, the thinnest is 0.01mm thick, amorphous, odorless, non-toxic, high transparency and low fogging. Chemical resistance: Dilute acid...

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.  ...
