What is Through-Hole Technology (THT)? Through-Hole Technology (THT) is a PCB assembly process where component leads are inserted into drilled holes on the PCB and soldered onto the opposite side of the board. This method has been used for decades and is still popular for certain applications. Advantages of THT […]

Planning and Design Techniques Create a Detailed Schematic Before you start building your circuit board, it’s crucial to create a detailed schematic. This schematic should include all the components, their values, and how they connect. Use software like KiCad, Eagle, or Altium Designer to create your schematic. Choose the Right […]

Introduction to PCB assembly PCB assembly refers to the process of attaching electronic components to a printed circuit board (PCB) to create a functional electronic device or product. The PCB serves as the foundation, providing the electrical connections between components. PCB assembly involves several key steps: Solder Paste Application Component […]

Introduction to PCB Forums A printed circuit board (PCB) forum is an online discussion board where electronics enthusiasts, engineers, designers, manufacturers, and hobbyists can ask questions, share knowledge, showcase projects, and discuss anything related to PCB design, fabrication, assembly, and troubleshooting.

Introduction to the 28BYJ-48 Stepper Motor The 28BYJ-48 is a Unipolar Stepper motor that operates on 5V DC and provides a step angle of 5.625 degrees per step. It comes with a built-in reduction gearbox that increases the torque and reduces the step angle, resulting in smoother and more precise […]

1. Visual Inspection The first and most basic method of checking for soldering defects is visual inspection. This process involves carefully examining the soldered joints and components on the PCB Board using the naked eye or a magnifying glass. Some common defects that can be detected through visual inspection include: […]

1. Bridging What is Bridging? Bridging, also known as solder bridges, occurs when excess solder creates an unintended connection between two or more adjacent pads or traces on a PCB. This defect can lead to short circuits and cause the device to malfunction. Causes of Bridging Excessive solder paste application […]

Why China is the Top Destination for Printed Circuit Boards China has become the go-to place for companies looking to manufacture printed circuit boards (PCBs) at scale. With its vast supply chain, skilled workforce, advanced factories, and cost advantages, China offers compelling reasons to source PCBs from its shores. Here […]

What is PCB Prototyping? PCB prototyping is the process of creating a physical printed circuit board (PCB) based on a design, for the purpose of testing and validation before mass production. A PCB Prototype allows designers and engineers to verify that their circuit design works as intended in the real […]

What are Prototype Boards? Prototype boards, also known as breadboards or development boards, are essential tools for electronics enthusiasts, engineers, and hobbyists. These boards provide a platform for quickly and easily creating electronic circuits without the need for soldering.
