Factors to Consider When Choosing PCB Substrate Materials Before diving into the specific types of PCB substrate materials, it’s essential to understand the key factors that influence substrate selection. These factors include: Dielectric Constant (Dk): The dielectric constant measures the substrate’s ability to store electrical energy. A lower Dk value […]

What is Clipping in Audio? Clipping is a form of waveform distortion that occurs when an amplifier is overdriven, and the output voltage exceeds the maximum voltage the amplifier can produce. In digital audio systems, clipping happens when the signal level exceeds the maximum digital value, resulting in a loss […]

Introduction to Zero-ohm resistors A zero-ohm resistor, also known as a jumper resistor or wire link, is a special type of resistor with negligible resistance, typically less than 0.005 ohms. Despite its name, a zero-ohm resistor does not actually have zero resistance, as this would be impossible according to the […]

What is a Multimeter? A multimeter, also known as a multitester or VOM (Volt-Ohm-Milliammeter), is an electronic measuring instrument that combines multiple measurement functions into a single device. It is used to measure various electrical parameters such as voltage, current, resistance, continuity, and sometimes even capacitance, frequency, and temperature. Types […]

Introduction to PCB Hacking PCB hacking, also known as printed circuit board hacking, is the process of modifying or repurposing PCBs for various projects and applications. It involves understanding the PCB design, identifying components, and making changes to suit specific needs. PCB hacking has become increasingly popular among hobbyists, makers, […]

Understanding the Basics of Voltage Regulation Before we dive into the specifics of the AVR PCB circuit, let’s first understand the fundamental concepts of voltage regulation. In an ideal power generation system, the output voltage should remain constant regardless of the load demands. However, in reality, various factors such as […]

What Are Semiconductor Chips? Semiconductor chips, also known as integrated circuits (ICs) or microchips, are the brains behind modern electronics. These tiny components, made from semiconductor materials like silicon, contain millions or billions of transistors that process and store data, enabling the functionality of devices such as: Computers and laptops […]

Introduction to Thermal Pads in PCB Design In the world of printed circuit board (PCB) design, managing heat dissipation is a critical factor in ensuring the optimal performance and longevity of electronic components.
