Introduction to ABS schematics Anti-lock braking systems (ABS) are a critical safety feature in modern vehicles. ABS prevents the wheels from locking up during heavy braking, allowing the driver to maintain steering control and reducing stopping distance. Understanding the schematics and components that make up an ABS system is important Read more…
Introduction to GSR Sensors Galvanic skin response (GSR) sensors, also known as electrodermal activity (EDA) sensors, are devices that measure the electrical conductance of the skin. The skin’s conductivity varies with changes in moisture level, which can occur due to emotional arousal or physical exertion. GSR sensors are widely used Read more…
What is Design Rule Check (DRC)? Design Rule Check, commonly known as DRC, is a critical step in the integrated circuit (IC) design process. DRC is an automated verification process that checks the layout of an IC design against a set of predefined design rules. These rules are established by Read more…
What is PCB Soldering? PCB soldering is the process of joining electronic components to a printed circuit board using a molten metal alloy called solder. The solder forms a strong electrical and mechanical bond between the component leads and the PCB pads, allowing current to flow through the circuit. Types Read more…
What is Soldering Flux? Soldering flux is a chemical cleaning agent used in soldering to help facilitate the soldering process. It is designed to remove oxidation from metals, prevent further oxidation during soldering, and help the solder flow more easily over the joint. Flux comes in several forms including liquid, Read more…
