Fire Hazard Pre-Detection: Detection of Odorous Gases Emitted from Circuit Boards In recent years, the proliferation of IoT has led to the high performance and miniaturization of electrical products, resulting in circuit boards developing towards higher density. This high-density circuit board is at risk of quality degradation due to long-term use and thermal accumulation, which … Read more
Recently, in the laboratory of the School of Materials Science and Engineering at Wuhan University of Technology, the hot press machine roared as it mixed, pressed, disassembled, and tested the performance of a high-frequency, high-speed, low-loss copper-clad laminate that was “ejected” by the machine. “The quality of 5G network signal transmission is crucially dependent on … Read more
The structure, manufacturing methods, and applications of printed circuit boards (PCBs) with electronic components. The core of this patent lies in improving heat dissipation efficiency by directly connecting heat dissipation elements to the wiring layer of the PCB, allowing for embedding in high-heat components such as power amplifiers. Key Concepts and Components Printed Circuit Board … Read more
Laminate imperfections in printed circuit boards (Laminate Imperfection) refer to internal and external defects that can be observed from the surface of the printed board. There are more than a dozen types of laminate imperfections, including Measling, Crazing, Delamination/Blistering, Foreign Inclusion, Weave Exposure, Mechanically Induced Disrupted Fiber, Scratch, Dent, Tool Mark, Surface void, Color Variation … Read more
This function detects the profile of the circuit board loaded into the machine and the F positioning point to perform stop position compensation, maintaining a fixed function. It can effectively address situations where the stop position fluctuates due to differences in the weight or size of the circuit board. 1. Installation of Low-Reflection Board If … Read more
The PCB height detection function of the NXT pick and place machine is a feature that measures the warpage of the circuit board transported onto the transport track. For circuit boards with warpage, in addition to ensuring stable component placement, if the warpage exceeds the tolerance value, please avoid production in advance to prevent the … Read more

What is a printed circuit board? A printed circuit board is a circuit formed by arranging conductive metal lines on an insulating substrate. In simple electronic projects, reconfigurable circuit boards such as breadboards or universal boards are often used, while printed circuit boards are fixed substrates that have these circuits pre-manufactured. The greatest advantage of … Read more
If we compare the CPU to a Swiss Army knife, the GPU is like a chainsaw—yet in the face of the AI biological revolution, what humanity needs is a weapon akin to neural synapses. The rise of NPU and TPU is not merely a technical iteration but a chip revolution that challenges the very genetic … Read more
AMD has announced two new products in its Ryzen Z2 series processors, the new flagship Ryzen AI Z2 Extreme and Ryzen Z2 A. The Ryzen Z2 series was initially launched in January this year, including the Ryzen Z2 Extreme, Ryzen Z2, and Ryzen Z2 Go. The Ryzen AI Z2 Extreme features specifications similar to its … Read more
