1.Visual inspection Since the layers in the PCB are tightly combined, it is generally not easy to see the actual number, but if you carefully observe the board fault, you can still distinguish it. If you are careful, we will find that there is one or more layers of white material in the middle of…
When designing a more complex board, you must make some design trade-offs. Because of these trade-offs, there are some factors that affect the design of PCB power distribution network. When the capacitor is installed on the PCB, there will be an additional loop inductance, which is related to the installation of the capacitor. The size…
There are very large differences in the scenarios, products, performance, materials, area, etc. when PCB is used, which leads to very large changes in the types of components used, the thickness of connecting wires, and the wiring density of different PCBs. Therefore, the degree of differentiation of different PCBs is very high. Generally, there are…
The most important feature of PCB is the high degree of customization. There are very large differences in the scenarios, products, performance, materials, area, etc. when PCB is used, which leads to very large changes in the types of components used, the thickness of connecting wires, and the wiring density of different PCBs. Therefore, the…
Introduction to PCB Green Mask and Via Plugging Printed Circuit Board (PCB) manufacturing involves numerous intricate processes that contribute to the final product’s functionality and reliability. Among these processes, the application of solder mask (commonly referred to as “green mask” due to its traditional color) and via plugging play critical roles in modern PCB production….
PCB wastewater is polychlorinated biphenyl wastewater, which is a type of wastewater in the printing industry and circuit board factory wastewater. At present, the world produces 300 million to 400 million tons of toxic and harmful chemical waste every year, among which persistent organic pollutants (POPs) are the most harmful to the ecology and the…
Here are some tips to help you understand how to do micro PCB design and fabrication. Today, the reduction in size of basic circuit boards will allow designers to reduce the size of their PCBs by half, or down to a quarter of the original size. Very fine lines that were previously unavailable to designers…
Learn how rigid PCBs compare to flexible PCBs, when it’s better to use one type over the other, and learn about some of the manufacturing steps associated with these PCB types. A Printed Circuit Board Isn’t Always a “Circuit Board” When the term “PCB” is used, many people think of a rigid PCB (printed circuit…
When it comes to high costs being a common crisis regardless of any improvement in economic conditions, many US industries are tracking effective ways to cut costs and upgrade profit margins without compromising on the quality aspects of product and process development, especially in the electronics industry. One of the hottest issues experienced by electronics…
Introduction to PCB Rails Printed Circuit Board (PCB) rails, also known as guard rails or edge rails, are essential conductive pathways that serve multiple purposes in electronic design. These rails typically run along the edges of a PCB or between critical components, providing structural support, electromagnetic shielding, and reliable power distribution. When properly implemented on…
The backplane PCB is a special type of circuit board that is usually located on the back or bottom of an electronic device to support and connect various electronic components and subsystems. Unlike conventional PCBs, backplane PCBs have a higher level and complexity to accommodate a large number of connectors, slots and other connection devices….
Introduction Printed Circuit Boards (PCBs) form the foundation of nearly all modern electronics, from smartphones to industrial control systems. Among the various specifications that define a PCB, thickness stands out as one of the most fundamental—and one where 1.6mm (approximately 0.063 inches) has emerged as the de facto standard for countless applications. This article explores…
Introduction Printed Circuit Board (PCB) design is a complex process that requires careful planning and precise execution. One of the most critical aspects of PCB design is setting up constraints to ensure signal integrity, manufacturability, and reliability. Constraints define the rules that govern trace widths, spacing, via sizes, and other design parameters. In this article,…
Introduction to PCB Relays Printed Circuit Board (PCB) relays are electromechanical switching devices designed specifically for mounting on printed circuit boards. These compact components serve as crucial interfaces between low-power control circuits and higher-power load circuits in countless electronic applications. PCB relays combine the reliability of electromechanical switching with the convenience of direct PCB integration,…
Printed circuit board (PCB) layout may be considered an art form by circuit designers, and there is a lot of truth to that. Creating the most reliable, functional, and cost-effective circuits and finished PCBs can be a challenging task, especially with today’s demand for increasingly complex requirements for compact, lightweight, and even flexible circuit boards….
