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…
Key Components of a Bill of Materials A typical BOM includes: BOM level: BOM level refers to the hierarchy of components in the BOM. Top level is usually indicated by 0 or 1, with subassemblies and components going down from there. Part number: Each part or component will have a Read more…
What is Mixed Assembly and How Does it Benefit Manufacturing? Mixed assembly is a manufacturing process that combines both automated and manual assembly techniques to create a more efficient and cost-effective production line. This approach takes advantage of the strengths of both methods while minimizing their weaknesses, resulting in improved Read more…
