What is PCB Warpage? PCB warpage, also known as PCB bow and twist, refers to the deformation or distortion of a printed circuit board (PCB) from its intended flat shape. This phenomenon can occur during various stages of the PCB manufacturing process, such as lamination, soldering, or even during the […]
Introduction to Circuit Board Components Circuit boards are the backbone of modern electronics. They are the foundation upon which all electronic devices are built, from simple gadgets to complex machines. A circuit board is a flat piece of insulating material, typically made of fiberglass or plastic, with conductive tracks, pads, […]
Introduction to Hartley Oscillators Hartley oscillators are a type of electronic oscillator circuit that uses a resonant circuit consisting of an inductor and capacitor to produce a sinusoidal output waveform. They are named after American engineer Ralph V.L. Hartley who invented the design in 1915 while working at Western Electric. […]
Introduction to BGA Soldering Ball Grid Array (BGA) is a surface-mount packaging used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package. The whole bottom surface of […]
What are Gold Finger PCBs? Gold finger PCBs, also known as edge connector PCBs or contact fingers, are printed circuit boards with gold-plated contact pads along one edge. These gold fingers allow the PCB to be plugged into a socket or slot for easy connection and disconnection. The gold plating […]
What are Arduino Shields? Arduino shields are expansion boards that can be connected to an Arduino board to add specific features or functionalities. They are designed to be plugged directly on top of the Arduino board, using the same pin layout and form factor. This allows for easy integration and […]
What is PCB Warpage? PCB warpage refers to the deviation of a PCB from its intended flat shape. It is a type of dimensional instability that occurs when the board experiences uneven thermal expansion or contraction during the manufacturing process or under certain environmental conditions. The warpage can be classified […]
Introduction to Proximity Sensors Proximity sensors are essential components in various applications, from industrial automation to consumer electronics. These sensors detect the presence of objects without physical contact, making them ideal for situations involving delicate or unstable objects. In this article, we will explore the working principles, types, applications, and […]
What is Conductive Paint? Conductive paint is a special type of paint that contains conductive materials, such as graphite or silver, which allow electricity to flow through it. Unlike traditional wires or printed circuit boards (PCBs), conductive paint can be applied to various surfaces, including paper, fabric, plastic, and even […]
