When creating a PCB project, one of the first steps is defining a PCB stackup. With this, you need to know which PCB material to use. You won’t be able to define a dielectric constant, which is critical for your impedance-controlled lines, if you haven’t decided on your PCB material yet.   Additionally, you’ll have…

When to Use Flexible and Rigid-Flex PCBs: Real Applications in Wearables and Medical Devices Are you planning to use flex PCBs on your projects? Can’t decide whether to use flexible or rigid-flex on them. This article should help you with your decision. Introduction Modern flex PCBs emerged when polyimide films were developed in the 1960’s….

After designing and bringing up a successful prototype, your next step could be to scale up for mass production. There are sizeable differences between preparing for a prototype build versus preparing for mass production. It’s important not to get overwhelmed with the process and plan. What’s good is that UET PCB (https://uetpcb.com/turnkey-pcb-assembly/) has a turn-key…

In every country, taxes and tariffs must be determined when importing or exporting products. The tax or tariff rates can vary depending on the type of product. In this case, the HS code system is used to correctly identify each product. The HS Code for PCBA is specifically used to identify PCBA-related products. PCBA products…

Today, electronic products have become a key part of our everyday lives. For example, from your smartwatch to your laptop and even machinery parts, everything is now electrical. However, at the heart of these electronic products is PCBA (Printed Circuit Board Assembly). But when it comes to importing and exporting them, the HTS code for…

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,…
