Overview of JST Connectors JST connectors are compact, rectangular-shaped connectors that use a crimp-style connection method. They consist of two main components: Housing – The plastic body that holds the metal contacts and provides insulation. JST housings come in different sizes, colors, and materials depending on the series. Contacts – […]

Introduction to PCB soldering Soldering is an essential skill for anyone working with electronic circuits and printed circuit boards (PCBs). PCB soldering involves joining electronic components to the conductive traces on a PCB using a molten metal alloy called solder. Proper soldering techniques ensure strong electrical connections and reliable circuit […]

What is Solder? Solder is a fusible metal alloy used to create a permanent bond between two or more metal surfaces. It is commonly used in electronic assembly and repair to join components to printed circuit boards (PCBs) or to create electrical connections between wires. Solder typically consists of a […]

Introduction to PCB Surface Finishing Printed Circuit Boards (PCBs) are essential components in modern electronics, providing a platform for electrical components to be mounted and interconnected. To ensure optimal performance and longevity, PCBs undergo a surface finishing process that protects the exposed copper traces from oxidation and enhances the solderability […]

Introduction to PCB Safety Distance When designing and manufacturing printed circuit boards (PCBs), it is crucial to consider the safety distances between various components, traces, and layers to ensure proper functionality, reliability, and compliance with industry standards. PCB safety distance, also known as clearance or creepage distance, refers to the […]

Introduction Solder mask, also known as solder resist or solder stop, is a protective layer applied to the copper traces of a printed circuit board (PCB) to prevent short circuits and corrosion. It also provides a surface for the application of silkscreen legends and component designators. One of the most […]

What is a DPDT Relay? A Double Pole Double Throw (DPDT) relay is an electromechanical switch that uses an electromagnet to control two separate electrical circuits simultaneously. It has two sets of contacts, each with a normally open (NO) and normally closed (NC) position, allowing for greater flexibility in switching […]

Introduction to Double Throw Relay A double throw relay, also known as a changeover relay or a SPDT (Single Pole Double Throw) relay, is an electrically operated switch that allows switching between two circuits. It consists of a coil, an armature, and a set of contacts. When the coil is […]

Understanding Motor Drivers A motor driver is an electronic circuit or module that is designed to control and drive motors. It receives control signals from a microcontroller or other control circuitry and translates them into appropriate power signals to drive the motors. Motor drivers are capable of handling the high […]

Understanding Firmware in Electronics Design Firmware is a crucial component in modern electronics design, serving as the bridge between hardware and software. It is a type of software that is embedded into a hardware device, providing low-level control and functionality. In this comprehensive article, we will delve into the world […]
