Author Introduction:Engineer Zhang，NPI Engineer。Some may not know this position, so let me explain it in a more understandable way. I am closely related to DFM – Design for Manufacturability analysis, which serves as a bridge between R&D and production. I often interact with electronic engineers, PCB layout engineers, and factories, and there is a lot … Read more
1. What is PCB? PCB (Printed Circuit Board) is the carrier for the electrical interconnection of electronic components, serving as a relay for transmission, and is thus referred to as the “mother of electronic products.” 2. Composition of PCB The materials of PCB mainly consist of two parts: PP semi-solid sheets and Core substrates, along … Read more
In the electronics manufacturing industry, printed circuit boards (PCBs) are critical components whose quality directly determines the performance of the final product. Choosing the right PCB factory is crucial, as it affects not only product stability but also project efficiency and cost control. Which PCB factory is the best choice? It depends on factors such … Read more
1. History of PCB Development The history of PCB development is a chronicle of the continuous miniaturization, integration, and high performance of electronic technology. 1. Concept Origin (Early 20th Century): The idea of “printing” wires on a substrate was first proposed by Germans Albert Hansen and Americans Charles Ducas, laying the theoretical foundation for PCBs. … Read more
PCB, known in Chinese as 印制电路板 (printed circuit board), is commonly referred to as a circuit board. If chips (such as CPU, GPU, etc.) are the “brain” of electronic products, responsible for thinking and computation, then the PCB serves as the “skeleton” and “nervous system” of electronic products. It supports all components (organs) and establishes … Read more
PCB (Printed Circuit Board) is a circuit board that connects and secures electronic components by printing conductive circuit layouts on an insulating substrate. It is a core component of electronic systems, often referred to as the “mother of electronic products,” and is widely used across various fields in modern society, including consumer electronics, healthcare, industrial … Read more
For those studying electronics, setting up test points on a circuit board is a natural practice. How many people have not heard of test points? And how many know about test points but do not understand their purpose?The primary purpose of setting up test points is to test whether the components on the circuit board … Read more
