This page looks at the PCB Editor's support for controlled impedance routing - configuring the routing widths and clearances, as well as the material properties and dimensions, to deliver the required routing impedance(s)
线路板材质(PCB material).doc,线路板材质(PCB material) According to the grade level, from bottom to height is divided as follows: 94HB/94VO/22F/CEM-1/CEM-3/FR-4 Details are as follows: 94HB: ordinary board, not fireproof (most low grade material, die
The base material is an important part of printed circuit boards. It determines the PCB board’s performance and scope of application. Different products have different requirements for the PCB base material. With the development of electronic technology, the industry has to push the limits and ove...
Fillers like silica improve dimensional stability, thermal conductivity and dielectric properties but increase cost. Q: What parameters indicate good drillability of a PCB material? Low thermal expansion, high decomposition temperature, and glass transition temperature above 150°C improve drillability. ...
HDI PCB material categories The first step in selecting dielectric materials for your high-density board is determining the operating frequency (Gbps or GHz) and allowable signal loss (dB). Next, you need to consider the material’s thermal, electrical, chemical, and mechanical properties. ...
