China's membrane switch manufacturer .Real-time quote:https://jrpanel.com/R

  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...

  PCB corrosion is caused by many different factors, such as Atmospheric Corrosion, Localized Corrosion, Electric Corrosion, Electrolytic Corrosion, Electrolytic Dendrite Formation, Fretting Corrosion and Intergranular Corrosion.   Corrosion can be extremely harmful to PCBs. Although there are many reasons that can cause PCB corrosion, there are several ways to clean it with traditional household products such as baking soda and compressed air. We can also take preventive measures to ensure that PCB corrosion will not occur in the future.   What Causes PCB Corrosion?   Corrosion of the circuit board can completely destroy the PCB, rendering it useless. There are many reasons for this corrosion, which is the oxidation process that occurs when oxygen combines with metal to produce rust and peeling.   Atmospheric Corrosion   Atmospheric corrosion is the most common type of PCB corrosion. The metal on the PCB is exposed to moisture, which in turn exposes i...

MORE 1. Features   As we all know, switches play a role in transmitting command information in electronic products. There are many varieties of switches, and their development is constantly updated with the progress of electronic products. In the 1950s, the toggle switch, toggle switch, and changeover switch of the Endeavour component were dominant; in the 1960s, a combination switch represented by the key switch appeared to complete simple function conversion; with the expansion and With the increase of the functions of the whole machine, conductive rubber keyboard switches appeared in the 1970s, and the membrane switch is a new type of electronic device researched and developed in the late 1970s and early 1980s. It conforms to the miniaturization and digitalization of electronic products. Intelligent, multifunctional development needs products.   Membrane switch is a switch made of conductive paste printed contact circuit on flexible polycarbonate or polyester film, which is...

  Online Pricing The heat generated by electronic equipment causes the internal temperature to rise rapidly. If the heat is not dissipated in time, the equipment will continue to heat up and the components will overheat and fail, resulting in a decrease in the reliability of electronic equipment. Therefore, PCB heat dissipation is a very important part. So how to design PCB heat dissipation?   1. Dissipate heat to the surrounding air through the surface of the PCB itself. However, with the miniaturization, high-density mounting, and high-heating assembly of electronic products, it is not enough to rely on the surface of a component with a very small surface area to dissipate heat. At the same time, due to the massive use of surface mount components such as QFP and BGA, a large amount of heat generated by the components is transferred to the PCB. Therefore, the best way to solve the problem of heat dissipation is to improve the heat dissipation capacity of the PCB its...

👉 https://www.jrpanel.com/R The manufacture of flexible PCBs involves several complicated steps, and extreme care must be taken. Some design or manufacturing defects can cause the entire circuit board to fail. During the PCB manufacturing process, please follow the precautions listed below: 1.  Use the right type and quantity of materials to maintain "flexibility". For example, if an application requires a 6-layer rigid-flex PCB that will bend during assembly and then should be kept in a fixed position, the correct type of copper and adhesive must be used. 2.  It is recommended to keep the circuit small. It is better to use a set of smaller circuits rather than a single larger circuit. 3.  It is not a good habit to bend flexible circuits around corners. However, some design situations require bending at the corners. In this case, you can make a gentle bend or use a conical radius bend. 4.  The copper used in the 6-layer rigid-flex board is easy to fall off the subst...
