This article serves as an introduction. Online programming, integrating programming and testing, has garnered increasing attention. To enhance programming efficiency, programming fixtures or jigs are often created, and the connection between the fixture, jig, and programmer typically requires longer wiring. The longer the wiring, the faster the signal attenuation, which increases the programming failure rate. … Read more
1.Definition A PCB buried via is a hole that connects different layers of conductive traces within a multilayer printed circuit board. Unlike through holes and blind vias, buried vias are completely hidden inside the PCB and are not visible on the surface. This design allows the PCB to maintain high-density routing while optimizing signal transmission … Read more
Introduction: This article discusses the potential interference from high-frequency electromagnetic waves in electronic signal processing circuits in practice. These situations are often omitted in ordinary classrooms and textbooks. The additional peripheral resistors and capacitors that seem unrelated to ordinary signal processing play a crucial role in ensuring circuit stability. Therefore, while encountering problems may cause … Read more
With the rapid development of new energy vehicle technology and the increasing application of renewable energy technologies, the market for high voltage signal isolators has experienced explosive growth. As we all know, to enable the interaction of electrical signals between two circuits, it is necessary to generate a flow of signal current and establish an … Read more
This is a very professional and important question, involving core considerations of hardware design and electromagnetic compatibility. Let’s break it down clearly. Core Explanation in One Sentence To ensure that the SPI interface does not generate excessive electromagnetic interference (EMI), and thus passes EMC certification, hardware design must set a maximum frequency limit based on … Read more
