Definition and Basic Concept Aspect Ratio is expressed as a ratio of two numbers, typically in the format of width:height. For example, a common aspect ratio in photography and digital displays is 16:9, which means that for every 16 units of width, there are 9 units of height. This ratio remains constant regardless of the […]
Why Use Blind Vias in PCB Design? There are several reasons why blind vias are used in PCB design: 1. Space Savings One of the main advantages of using blind vias is that they save space on the PCB. Since blind vias do not go all the way through the board, they free up space […]
What is BGA Soldering? BGA soldering is a method of attaching electronic components, such as microprocessors and memory chips, to a PCB using an array of small solder balls. These solder balls are arranged in a grid pattern on the bottom of the component package, allowing for a high number of connections in a small […]
Introduction to High-Voltage PCB Design High-voltage printed circuit boards (PCBs) are essential components in various applications, including power supplies, industrial control systems, and medical equipment. Designing high-voltage PCBs requires careful consideration of several factors to ensure reliable performance, safety, and longevity. In this article, we will explore the key aspects of high-voltage PCB design and […]
Introduction to Cold Solder Joints A cold solder joint is a common problem in electronic assemblies that occurs when the solder fails to properly bond with the surfaces being joined. This can lead to a dry, cracked, or incomplete connection that may cause intermittent or complete failure of the circuit. Cold solder joints are often […]
Introduction to PCB Drilled Holes Printed Circuit Boards (PCBs) are essential components in modern electronics, providing a platform for interconnecting various electronic components. One crucial aspect of PCB manufacturing is the creation of drilled holes, which serve multiple purposes, such as mounting components, establishing electrical connections between layers, and facilitating heat dissipation. In this article, […]
Introduction to Buried Vias A buried via is a type of interconnect used in printed circuit board (PCB) design to connect different layers within the middle layers of the board, rather than connecting to the outer layers. Unlike through-hole vias which go through the entire board from top to bottom, buried vias are embedded within […]
Introduction to PCB Bottom The printed circuit board (PCB) is a fundamental component in modern electronics. It serves as a platform for mounting and connecting various electronic components to create a functional circuit. A typical PCB consists of two sides: the top side and the bottom side. In this article, we will focus on the […]
How Does a Desoldering Braid Work? A desoldering braid consists of a fine copper wire that is tightly woven into a flat, ribbon-like structure. The copper wire is typically coated with a thin layer of flux, which helps to facilitate the removal of solder. When heated with a soldering iron, the desoldering braid absorbs the […]
What Causes Lifted Pads on PCBs? There are several potential causes of lifted pads on printed circuit boards: Incorrect Hole Drilling One common cause is incorrect hole drilling during PCB fabrication. If the holes for through-hole components or vias are drilled off-center from the pads, there will be less bonding area between the pad and […]
