Introduction to Transformerless Power Supply A transformerless power supply is an electronic power supply that does not use a transformer to convert AC mains voltage to a lower AC voltage for rectification. Instead, it uses capacitive or resistive voltage dividers to step down the high voltage AC mains to a […]

Introduction to Flex PCBs Flexible printed circuit boards (Flex PCBs) have gained significant popularity in recent years due to their versatility and ability to conform to various shapes and sizes. Unlike traditional rigid PCBs, flex PCBs are designed to bend and twist, making them ideal for applications that require flexibility, […]

Introduction to PCB Thickness Printed Circuit Boards (PCBs) are the backbone of modern electronics. They provide the foundation for electronic components to be mounted and interconnected, enabling the functioning of various devices. One of the crucial aspects of PCB design and manufacturing is determining the appropriate PCB thickness. The thickness […]

What Are Single-Layer PCBs? A single-layer PCB, also known as a single-sided PCB, is a printed circuit board that has conductive traces on only one side of the insulating substrate. The conductive traces are usually made of copper and are used to connect various electronic components, such as resistors, capacitors, […]

What is a Rigid-Flex PCB? A Rigid-Flex PCB, also known as a Rigid-Flex Circuit, is a unique type of printed circuit board that combines the benefits of both rigid and flexible PCBs. It consists of multiple layers of flexible PCB substrates, such as polyimide, that are laminated together with traditional […]

Introduction to PCB Circuit Boards A Printed Circuit Board (PCB) is the foundation of nearly all modern electronic devices. It provides mechanical support and electrical connections for electronic components using conductive pathways, tracks, or signal traces etched from copper sheets laminated onto a non-conductive substrate. PCBs have revolutionized electronics manufacturing […]

Introduction to PCB Stack-up A printed circuit board (PCB) stack-up refers to the arrangement of copper layers and insulating materials that make up a PCB. The stack-up determines the electrical properties, signal integrity, and manufacturability of the board. As PCBs become more complex, with higher layer counts and increased density, […]

What is a Microvia PCB? A microvia PCB is a printed circuit board that incorporates microvias – tiny holes that are less than 150 microns (μm) in diameter. These microvias enable high density interconnects between layers within the PCB. They allow for finer pitch components, reduced layer count, and smaller […]
