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 the semiconductor foundry or fabrication facility to ensure that the design can be reliably manufactured using their specific process technology. DRC is essential because it 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 in research, clinical settings, and consumer applications to monitor stress, emotional states, and other physiological responses. How GSR Sensors Work GSR sensors work by measuring Read more…

What is ODB++? ODB++ is a file hierarchy format that contains all the necessary information required for PCB fabrication, assembly, and testing. It is an open format, meaning that it is not proprietary to any specific CAD or CAM system, allowing for seamless data exchange between different software tools. The ODB++ Format consists of a directory structure that organizes the various files and data related to a PCB design. This structure includes: Job file (.job) 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, paste, and solid. The most common types used in electronics soldering are rosin-based fluxes which are available in various activity levels. Types of Soldering Flux Read more…
