PCB (Printed Circuit Board) is the core foundational component of electronic devices, often referred to as the “mother of electronic products.” It forms circuit connections on a common substrate according to a predetermined design, providing mechanical support, electrical interconnection, and signal transmission functions for electronic components. PCBs are widely used in almost all electronic products, … Read more
Today’s news: (1) The cowop process, which uses PCB to replace cowos, allows chips to be directly packaged onto the PCB, potentially increasing the requirements for PCB to mSAP technology; (2) Orthogonal backplanes may adopt mSAP technology. #mSAP technology benefits manufacturers: Shenghong Technology: One of the suppliers of orthogonal backplanes, with high-end HDI processing capabilities. … Read more
1. HDI Technology Upgrade: In NVIDIA’s AI servers, to meet the demand for massive data transmission, the number of PCB layers has increased from the traditional 8 layers to 20 – 30 layers, and the materials have been replaced with high-speed, low-loss specialty substrates. The upgrade of the 1.6T switch has driven the upgrade of … Read more
PCBEngineers often find multilayer circuit boards confusing at first glance, especially with layers reaching ten or more, resembling a spider web.Below are several internal structure diagrams of multilayer PCBs, showcasing various stacking structures in a three-dimensional format. 01 The core of High-Density Interconnect (HDI) boards lies in the vias. The processing of multilayer PCB traces … Read more
During the outbreak of the pandemic in 2020, I found myself staring at the K-line chart of PCB leader Huadian Co., feeling frustrated — who would have thought that a small circuit board could become the “throat” of the global technology supply chain? That year, when Huawei was cut off from chip supplies, the entire … Read more
