How Does Via-in-pad plating Work? The via-in-pad plating process involves several key steps: Via Drilling: First, holes are drilled through the PCB substrate at the locations where the vias will be placed. These holes are typically drilled using high-speed mechanical drills or laser drills, depending on the size and precision […]

What is Opamp Hysteresis? Opamp hysteresis, also known as positive feedback or Schmitt Trigger, is a technique used in operational amplifier circuits to create a threshold voltage that must be exceeded before the output switches states. In other words, it introduces a deliberate amount of hysteresis or “dead zone” between […]

Understanding the PCB Manufacturing Process The PCB manufacturing process consists of several key stages, each of which plays a crucial role in determining the quality of the final product. These stages include: PCB Design PCB Fabrication PCB Assembly PCB Testing and Inspection PCB Design The PCB design stage is where […]

What is a Motion Sensor Light? A motion sensor light is a type of light fixture that automatically turns on when it detects movement within its range. These lights are commonly used for outdoor security, energy efficiency, and convenience. They are equipped with a passive infrared (PIR) sensor that detects […]

What is a Robot Chassis? A robot chassis is the main structural frame of a robot that supports all the components such as motors, batteries, circuits, and sensors. It provides the foundational base upon which the rest of the robot is built. The chassis must be strong and rigid to […]
