High efficiency is a common requirement for power supplies and electronic devices. Improving the working efficiency of high frequency transformers can save power. It also has double social and economic benefits of environmental protection. Therefore, improving efficiency is a major design requirement. Generally speakin...

Drawing design is important for PCB, so how to check if it doesn't goes wrong? After the circuit board wiring is settled, check the PCB for rules to ensure that the circuit board meets the design requirements. All nets should be connected correctly. Commonly used inspection items in design rules are as follows: Che...

Nowadays, the traditional injection molding process can no longer meet the surface requirements, especially in the rapid developing fields of electronic consumer products. Mobile phones and wearable devices are what I'm talking about. These products have extremely high requirements on appearance, abrasion resistanc...

1. Working Principle High frequency transformer is a component that converts alternating voltage, current, and impedance. When an alternating current flows through the primary coil, an alternating magnetic flux is generated in the iron core (or magnetic core). At the same time, the voltage (or current) is induced in th...

Switches are components that control the circuits in modern times. You can see them everywhere. All kinds of switches work in equipment such as electric lights, microwave ovens, and large machines. Everything improves in daily life, so various types of advanced switches appear. Let's take a look at the development ...

1. Manufacturing Clean the surface of the membrane switch that needs treatment (the surface is required to be flat, rust-free, oil-free, and dust-free) Inspect and compare the size (put the membrane switch to the place to be pasted, and compare the size and position to see if everything's good). Peel off the centri...

1. Introduction Membrane switch is a multi-layer structure switch with elasticity. It is composed of insulating material layers. The component is flat and non-locked. You can see membrane switches everywhere, ranging from small household appliances to high-tech products. They are widely popular in many fields because o...

Practitioners in electronics field all know ROHS and REACH. However, people may have a confusion about difference between ROHS and REACH. There are always some questions, "Doesn't REACH include ROHS?", "Why do I need a ROHS report if I have a REACH report?" So, what is the truth? Let's talk ...

Acrylic sheet is a kind of organic glass that has been specially treated. It can be endowed with different colors by screen printing. In a way, acrylic sheet is an upgrade product of organic glass. You must have seen some light boxes made by this good material. It owns good light transmission. The pretty and flat produ...

PCB and PCBA, as important components in the electronics industry, play key roles in electrical interconnection and circuit. The printed circuit board provides the fixing and electrical connection of electronic components. And PCBA, as the manufacturing process of the printed circuit board, completes the assembly and w...
