Introduction to PDF, Gerber, and NC Drill Formats PDF (Portable Document Format) is a widely used file format for exchanging and printing electronic documents. It was developed by Adobe in the 1990s and has since become the standard for sharing documents across different platforms and devices. PDFs can contain text, […]

What is an AC-DC Converter? An AC-DC converter is an electronic device that takes alternating current (AC) input from the power grid and converts it into direct current (DC) output suitable for powering various electronic devices. The converter rectifies the AC input, filters it, and regulates the output voltage to […]

What are Gerber Files? Gerber files, also known as Gerber format or Gerber image format, are the industry standard for printed circuit board (PCB) designs. These files contain essential information for PCB Fabrication, including copper layers, Solder Mask, silk screen, and drill data. Gerber files are generated by PCB Design […]

Introduction to Class C Amplifiers Class C amplifiers are a type of electronic amplifier where the active element (usually a transistor or vacuum tube) conducts for less than 50% of the input signal cycle. They are one of the most efficient types of RF power amplifiers but have higher distortion […]

Introduction to the TL494 The TL494 is a versatile pulse width modulation (PWM) control circuit that is widely used in power supply applications. It is designed to provide all the necessary features for building a high-performance power supply, including voltage and current control, undervoltage lockout, and output protection. In this […]

Introduction to PCB Etching Printed Circuit Board (PCB) etching is a crucial process in the manufacturing of electronic devices. It involves removing unwanted copper from the surface of the PCB to create the desired circuit pattern. The choice of etching method can significantly impact the quality, precision, and efficiency of […]

Introduction to the BMP280 and BME280 Sensors The BMP280 and BME280 are two popular environmental sensors used in a wide range of applications, from weather monitoring to IoT devices. Both sensors are produced by Bosch Sensortec and offer high-precision measurements of atmospheric pressure, temperature, and in the case of the […]

Introduction to PCB Edge Plating Printed Circuit Board (PCB) edge plating, also known as metalizing circuit board edges, is a process that involves coating the edges of a PCB with a conductive material, typically copper. This process is crucial for various applications, such as providing electrical connectivity, enhancing mechanical strength, […]

Introduction to PTC Thermistors PTC (Positive Temperature Coefficient) thermistors are temperature-sensitive resistors whose resistance increases significantly with rising temperature. Unlike traditional resistors that maintain a relatively stable resistance across a wide temperature range, PTC thermistors exhibit a sharp increase in resistance once they reach a specific temperature threshold, known as […]

What is a Heat Sensor Circuit? A heat sensor circuit is an electronic device that consists of a temperature-sensitive component, such as a thermistor or a thermocouple, and additional circuitry to process the sensor’s output. The temperature-sensitive component changes its electrical properties in response to changes in temperature, allowing the […]
