The “surface” here refers to the connection points on the PCB that provide electrical connections between electronic components or other systems and the circuits of the PCB, such as pads or contact connections. Bare copper itself has good solderability, but it is easily oxidized and easily contaminated when exposed to air. This is why PCBs…

Designing a printed circuit board (PCB) is the delicate process of turning a circuit schematic into a real application. You need to consider many factors in a real circuit that will affect your results almost as much as the quality of your schematic. Unlike theoretical components, real-world devices generate heat, wires and traces have inherent…

Top 10 Quality Problems and Solutions of PCB Products that Newbies Must Know In the entire production process, there are many control points. If you are not careful, the board will be damaged. PCB quality problems are endless, which is also a headache, because if only one of them has problems, most of the components…

In the field of electronic products, PCB (Printed Circuit Board) is an extremely critical component. Whether it is a high-speed circuit, a high-frequency circuit or a millimeter-wave related product, it is indispensable. The processing of PCB boards is a complex system engineering, covering multiple aspects such as PCB materials, potions, processing technology and line geometry…

For hardware engineers, the level of PCB design directly affects the performance and stability of electronic products. In the previous series of articles, we explored many key points of PCB design. This article will continue to go deeper and focus on some aspects that are easy to overlook but crucial, helping hardware engineers to further…

Introduction Today’s electronic products are no longer like the TVs and refrigerators of the 1970s, which consumers only replaced every ten years. Now almost every member of every family is a consumer of electronic products, and as technological development continues to bring a variety of affordable new features to smartphones, tablets, cars and TVs, people…

Recently, I have been doing ESD testing of electronic products. From the test results of different products, I found that this ESD is a very important test: if the circuit board is not designed well, when static electricity is introduced, it will cause the product to freeze or even damage the components. In the past,…

PCB (Printed Circuit Board), Chinese name is printed circuit board, also known as printed circuit board, printed circuit board, is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made by electronic printing, it is called a “printed” circuit board. There are two…
