Circuit board reliability and micro-sectioning 1.Abrasion Resistance In circuit board engineering, it often refers to the wear resistance of solder-proof green paint. The test method is to use a 1 kg soft grinding wheel to rotate and rub 50 times on the IP-B-25 sample board that has been painted green. The comb-shaped circuit area must…

Introduction to the electrophoretic photoresist method for the production of MID three-dimensional substrates I. MID three-dimensional substrates and traditional flat circuit boards PCB The design and manufacturing of electronic products are moving towards being thin, short and small, and circuit boards are also clearly developing towards fine lines and multi-layers. In terms of the control…

If the design contains a high-density FPGA, there are likely to be many challenges in front of the carefully designed schematic. Hundreds of inputs and outputs, operating frequencies exceeding 500MHz (and possibly higher in some designs), and solder ball pitches as small as half a millimeter all lead to unwanted interactions between design elements. Concurrent…

The key tasks of my country’s copper clad laminate (CCL) industry in the future development strategy, specifically speaking, should be to work hard on five major categories of new PCB substrate materials, that is, through the development and technological breakthroughs of the five major categories of new substrate materials, to improve my country’s CCL cutting-edge…

Anti-interference is a very important part of modern PCB circuit design, which directly reflects the performance and reliability of the entire system. At present, the anti-interference technologies used in the system mainly include hardware anti-interference technology and software anti-interference technology. 1) Design of hardware anti-interference technology. The inverter circuit of the flywheel energy storage system…

As frequencies continue to increase, controlling the phase consistency of PCB materials becomes increasingly difficult. Accurately predicting the phase change of PCB materials is not a simple or routine task. The signal phase of high-frequency and high-speed PCBs depends largely on the structure of the transmission lines made from them, as well as the dielectric…

The design of PCB boards for stable working of switching power supplies now summarizes seven tricks: by analyzing the matters that need to be paid attention to in each step, you can easily design the PCB board step by step! 1.Design process from schematic diagram to PCB Establish component parameters-》Enter principle netlist-》Design parameter setting-》Manual layout-》Manual…

Designing and building the next generation of electronic products is a complex process, especially in a highly competitive global industry like the electronics industry, where rapid and continuous technological changes have become a common occurrence and the rule of innovation. If designers cannot accept these changes, they will face the risk of being left behind…
