We often need multimeters to measure various electrical values. We use it daily for many technical tasks. A multimeter helps us check voltage, current, resistance, and continuity. From home repairs to professional electrical work, multimeters are indispensable. However, you may feel confused when you first look at the dial and buttons. That’s where understanding multimeter…

We all know that air conditioners play a crucial role in keeping our homes and offices cool. But for efficient operation, the most crucial electrical component is the AC capacitor. When you open an AC unit and look at the capacitor, you will find several colored wires. These wire colors can be confusing for beginners….

GND is a fundamental term used in electronics. In fact, you’ll see it written on almost all modern devices that use electricity. Many people don’t know the  meaning of GND, so they ask, “What is GND in electronics?” Understanding the basics of GND is crucial because it completes the circuit and makes devices work. Without…

The world of electronics literally depends on direct current (DC). Alternating currents are unsafe for most sensitive electronic devices. However, if not using batteries, the alternating current is first converted to direct current. Which then becomes suitable for use in the device. But not all devices use the same level of dc voltage. Each device,…

Most modern electronic devices rely on signal regulation to work correctly. You may think of audio amplifiers, power amplifiers, motor controllers, and many sensor modules. On a PCB, even a small change in voltage can affect performance. That is why you need to include adjustable components to fine-tune signals during setup. A proper potentiometer wiring,…

Electronic devices look simple from the outside. However, they involve complex components such as resistors, capacitors, and chips. All these components are mounted on the PCB (Printed Circuit Board) of these electronic devices through SMT technology. But many don’t know about SMT meaning in electronics. Generally, SMT is confused with SMD, which is obviously wrong….

When you are dealing with PCB, precision and stable components are crucial. Proper heat dissipation, the correct number of PCB layers, trace sizes, and PTHs are all essential in ensuring the best PCB performance. In this case, choosing the proper PCB fabrication manufacturer is very important. PCBs are small boards that power machines and electronics….

A laptop computer is a big part of our daily lives. Desktop computers are typically larger and work with a combination of various devices. It’s tough to move it where you go. Here, the need for portable computers arose, and the laptop emerged. However, compressing the entire desktop into a small book was not easy….

China has become the global hub for printed circuit board (PCB) manufacturing. It is home to hundreds of companies that promise top-quality products and reliable service. However, with so many options, finding the right manufacturer can often feel overwhelming. To make your search easier, I have researched and shortlisted the top 10 best PCB manufacturers…

PCBs are an integral part of almost every modern electronic gadget. You will find PCBs in smartphones and laptops, as well as in cars and home appliances. But before a PCB becomes a working part of a product, it must go through a process called PCB assembly. Have you ever wondered: How much does PCB…
