We will encounter various safety spacing issues in ordinary PCB design, such as the spacing between vias and pads, the spacing between traces and traces, etc., which should be considered. . So today we will divide these spacing requirements into two categories, one is: electrical safety spacing; the other is: non-elect...

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 maint...

The choice of components and the size of the PCB are interdependent. Therefore, when choosing the right components for rigid flexible printed circuit boards (PCBs) or other types of PCBs, the footprint of the PCB must also be considered. The package is the basic layout of the PCB. It includes electrical and mechanical ...

Learning to contact a new technology will always encounter various problems, and learning EMC is no exception. EMC includes two parts: EMS and EMI. Generally speaking, solving the EMC problem is actually solving the external radiation interference of electronic equipment, or how to prevent the equipment and electronic ...

In Membrane Switch production, we use LEDs very often. Today, we are going to introduce LED Aluminum Substrates. As soon as LED aluminum substrates came to the market, the development of the heat dissipation application industry started. Because of the heat dissipation characteristics of LED aluminum substrates, and al...

1. Shape: shape, conductor line, insulation treatment, liner combination, etc. should meet the requirements of the drawing or provide physical samples. 2. Material: panel, substrate, silver paste, carbon ink, spacer, adhesive, adhesive, reinforcing plate, insulation printing should meet the requirements of the drawing....

White light LED is a voltage-sensitive device. In actual work, the current is 20mA as the upper limit, but the current will often increase due to various reasons in use. If no protective measures are taken, this increased current The LED will be damaged after a certain time and range. The main reasons for LED damage ar...

Two common faults of microwave ovens are mostly related to membrane switches or FPC printed circuits: (1) Failure of most switches in the keyboard. Leakage of electricity on thin-film switches or FPC is a common cause of such failures. Leakage is caused by long-term damp or moisture erosion on the microwave computer bo...

From hospital equipment and engineering controls to telephone systems and household appliances, membrane keyboard are used in a wide variety of applications. At first glance, one might assume that a membrane keyboard is nothing more than a standard keyboard, similar to the type used with computers. While they share som...

Membrane switch is an integral sealing structure composed of flat multi-layer films. The key switch, panel, mark, symbol display and liner are sealed together. The integration of light, mechanism, electricity, and integration rose in the 1980s. A new type of electronic components that can perform operating system tasks...

The colors which are used in a company’s logo or other interface design have a major impact on how the company (brand) is viewed as a whole. Color reference guides (like Pantone) and Adobe color tools make it fast and easy to select colors. But they don’t always translate well into the final production process. You h...

History has fixed in the minds of membrane-switch engineers the belief that 100 ohms is the maximum circuit resistance they should build into their products. The ability to achieve this low level of circuit resistance was made possible through the availability of highly conductive silver inks with volume resistivities ...
