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 […]

Introduction Soldering is a crucial process in the creation of electronic devices, and choosing the right solder is essential for ensuring the quality and longevity of your circuit boards. With so many different types of solder available, it can be challenging to know which one is best suited for your […]

What is an SPDT Relay? An SPDT (Single Pole Double Throw) relay is an electromechanical switch that uses an electromagnet to control the switching of electrical contacts. It has one common terminal and two switchable terminals, allowing it to switch a circuit between two different paths. When the relay coil […]

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 […]

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 – […]

What are PCB Traces? PCB traces are thin copper lines that are etched or printed onto the surface of a PCB. They serve as the electrical pathways that allow signals and power to flow between various components such as resistors, capacitors, integrated circuits (ICs), and connectors. The width, thickness, and […]
