As smart devices continue to pursue slimmer profiles and higher performance, traditional PCBs can no longer meet the demands of complex application scenarios. Qinji’s newly launched 6-layer HDI rigid-flex PCB, with its innovative structure and premium manufacturing process, redefines the possibilities of high-density interconnection.

In the field of new energy power electronics (PV / energy storage / EV charging piles), PCBs are subject to extremely high requirements for precision, reliability and integration density. The 10-layer 1+1 HDI board launched by Qinji PCB Cloud is a high-performance solution designed to meet these stringent demands.

They seem similar: both are high-end PCBs that require impedance control and signal quality assurance. They are often used together: one board can carry both RF and high-speed digital signals. Industry habit: People commonly say "high-frequency and high-speed boards", so they gradually become regarded as a single concept. But in professional design and manufacturing, they follow completely differe

In PCB production communication and specification sheets, we often hear "1oz copper thickness" and default that it corresponds to approximately 35 microns (μm). This seemingly regular value is not arbitrarily set, but a result of precise physical definitions, unit conversions, and industry practice conventions. The logic behind it is clearly explained from three aspects: definition, conversion, an

Ceramic substrates have become the cornerstone of high-power, high-density electronic packaging due to their excellent insulation, thermal conductivity, and mechanical stability. Metallization, the key process of forming conductive layers on ceramic surfaces, directly determines the electrical connectivity, thermal management, and long-term reliability of PCB ceramic substrates.
