In a manufacturable HDI board, Return paths are often not obvious in schematics, but they actually are one of the critical points for the performance of HDI PCB.The signal quality relies not just on the signal trace itself, but also on the continuity and stability of return current paths. ...
Designing Heavy Copper PCBs for Current Handling and Manufacturability Why Use Heavy Copper PCBs? Start with a definition of Heavy Copper PCB: Heavy copper PCBs generally refer to boards with 3 oz (1oz≈35μm) copper or more on the outer or inner layers, that depending on the fabrication spe...
In high-reliable and manufacturable HDI design, we often regard stackup of a HDI board as a layer arrgangement. However, in the real practice, the function of the HDI board structure is not just about the layer of HDI PCB. A HDI construction is the fundamental of the HDI board design, it direc...
