The pilot project of PCB comprehensive wastewater deep treatment led by the Institute of Process Engineering of the Chinese Academy of Sciences was launched in Wuxi in December 2025. Through the three-level process of "electrocatalytic oxidation+gradient membrane separation+copper crystallization recovery", the heavy metal ion concentration is less than 0.05mg/L and the reuse rate is greater [...]

New energy vehicle electric drive, OBC (on-board charger), DC-DC converter and other power modules commonly use aluminum/copper based metal core printed circuit boards (MCPCBs), which conduct heat directly through the metal substrate, reducing the IGBT junction temperature by more than 20 ℃. Industry data shows that by 2025, the installation volume of MCPCB vehicles in [...]

According to industry estimates, the PCB value of a single 5G base station is about five times that of a 4G base station, mainly due to the increasing demand for multi-layer, high-frequency high-speed boards such as RF front-end, Massive MIMO antenna array, and high-speed return interface. However, the core formula and patents of upstream high-frequency [...]

Before the completion of the environmental impact assessment approval for the 200000 square meter printed circuit board technology renovation project of Weili Guang Technology, a public announcement was made, which clearly requires that organic waste gas be treated with water spray and secondary activated carbon, acidic waste gas be treated with dilute alkali washing tower, [...]

Since 2024, driven by downstream factors such as AI servers, 5G base stations, and optical modules, the PCB industry has shown a dual logic resonance of "cycle+growth", with the off-season output value in the first quarter exceeding 8% of the same period last year. High speed, high-frequency, high layer count, and high heat dissipation requirements [...]

commemorate the 54th anniversary of the birth of Intel 4004, a technical team reconstructed a complete MCS-4 computer system based on original engineering drawings using discrete components, including seven huge printed circuit boards, reproducing all the logical functions of the Busicom calculator. This project has become a model of "digital archaeology" in hardware history.

With the rise of open-source big models such as DeepSeeker R1, AI is accelerating its integration into the field of industrial automation. There are intelligent manufacturing solutions demonstrating how to use AI platforms to achieve virtual testing and parameter optimization of PCB assembly production lines, improving the flexibility and efficiency of hybrid production. This trend [...]

HealthCanada has issued a warning that an implantable device used in a certain neuromodulation system may cause intermittent signal interruption or loss of imaging function due to contamination of the chip bonding layer on the printed circuit board assembly (PCBA), and has been classified as a Level II recall event. This reflects the importance of [...]

The annual production of 4 million square meters of printed circuit boards in a certain area has attracted attention during the environmental impact assessment public announcement stage. Due to the expansion project involving the doubling of soft and hard board production capacity and the need to treat hazardous wastewater containing cyanide, nickel, etc., relevant departments [...]
