What is a Multilayer PCB? A multilayer PCB (Printed Circuit Board) is a complex circuit board that consists of multiple layers of conductive copper foil laminated together with insulating material. These layers are interconnected through vias, which are small holes drilled through the board and plated with conductive material. Multilayer […]

Introduction to MOSFETs Metal-oxide-semiconductor field-effect transistors, or MOSFETs, are voltage-controlled semiconductor devices widely used for switching and amplifying electronic signals. MOSFETs have revolutionized the electronics industry due to their high input impedance, fast switching speeds, and excellent power efficiency compared to bipolar junction transistors (BJTs). MOSFETs are divided into two […]

What is a Bare PCB? A bare printed circuit board, also known as a blank PCB, is the foundation of any electronic device. It is a flat, rigid board made of insulating material, typically fiberglass or composite epoxy, with conductive pathways etched onto its surface. These pathways, called traces, connect […]

What is PCB Etching? PCB etching is a critical process in the manufacturing of printed circuit boards (PCBs) where unwanted copper is removed from the surface of the board, leaving behind the desired copper traces that form the electrical connections. Etching is typically performed using chemical solutions that selectively dissolve […]

What are Active Components? Active components are electronic devices that require an external power source to operate and can control the flow of current in a circuit. They have the ability to amplify, switch, or modulate electrical signals, making them essential for various electronic applications. Active components play a crucial […]

How Does Surface-mount technology Work? In surface-mount technology, the components are placed directly onto the surface of a printed circuit board. The components are typically smaller than their through-hole counterparts and have small metal tabs or end caps that can be soldered directly to the PCB’s surface. The components are […]
