Choosing the right dielectric material for a PCB is important no matter what application you’re working. However, the stakes are higher with High-Density Interconnect (HDI) technologies. They’re small, light, and powerful, yet they have specific construction...
Use these four tips to become a high density interconnect printed circuit board design master.
The digital world is getting complex hour by hour whereas the hardware associated with it is getting drastically smaller. The advantages of HDI PCBs are numerous, starting with more interconnections in smaller areas. This results in the miniaturization of boards that...
One thing PCB designers will all agree on is that to breakout a BGA, you need precision and discipline. When you breakout a BGA, you basically apply a fanout solution. You route traces from those fanouts to the perimeter of the device prior to general routing of the...
Several big trends have converged to make the Internet of Things possible, including advances in PCB design.
If Sierra Circuits was making burgers, we would make the world’s best burgers, just like we make the world's best PCBs. We would prepare each layer of your burger with care and tenderness, just like the layers on our PCB stack-up. Our burgers will come with different...
Our first HDI webinar is entitled ''An HDI Class with Sierra Circuits.'' We recorded it at our Bangalore office in June 2019 with Vadiraj Kulkarni, Senior PCB Consultant. As the name suggests, this HDI webinar is actually a class. During the recording, we had our...
High-Density Interconnection or HDI substrates are multi-layer, high-density circuits with features including the fine line and well-defined space patterns. Increasing adoption of HDI substrates enhances the overall functionality of PCBs and limit the operational...
Vias are miniature conductive pathways drilled into the PCB to establish electrical connectivity between the different layers. Basically, a via is a vertical trace in a PCB. In this article we will cover: What is a via? Aspect ratio for vias in PCBs Aspect ratio chart...
