via hole meaning in English
导通孔
通路孔, 辅助孔
Examples
- Any layer inner via hole
任意层内部导通孔 - Landless via hole
无连接盘导通孔 - Interstitial via hole : an embedded through - hole with connection of two or more conductor layers in a multilayer pcb
埋孔：多层pcb内的连接两个或以上导体层的镀通孔。 - The difficulty in design microstrip pin sp3t switch is the via hole for grounding . we use both the radial parts and the via hole to get a good result . the fin - line pin switch is fully simulated using full - wave analysis , the parasitic parameter and the circuit assemble need to be considered
微带结构上过孔微波接地效果的不理想,是微带单刀三掷开关的难点,本文采用了扇形的微波接地和过孔直流接地结合起来,较好的解决了这一问题。 - Coplanar waveguides ( cpw ' s ) offer several advantages over conventional microstrips , these include the simplification of the circuit fabrication process , ease of parallel and series insertion of both active and passive components ( without the need for via holes ) , and high circuit density . therefore cpw ' s are widely used in microwave and millimeter - wave integrated circuits , optical and high temperature superconductor microwave devices
与常规的微带传输线相比，共面波导具有容易制作，容易实现无源、有源器件在微波电路中的串联和并联(不需要在基片上穿孔) ，容易提高电路密度等优点，因此共面波导被广泛应用于微波、毫米波、光学和高温超导等集成电路中。
