Flexible printed circuit boards (PCBs) are those, which have conductor patterns printed on a flexible insulating film. The rigid PCBs are responsible to hold all the components. The flexible film connects two rigid PCBs. Thus, rigid flex PCBs are a combination of both, rigid, and flexible PCBs. This is a permanent combination, meaning these two types of PCBs are permanently connected to each other. You can get custom manufactured asymmetrical rigid flex printed circuit boards having outward flexible layers, or symmetrical rigid flex PCBs with inward flexible layers.

HDI PCBs are manufactured with several prominent features. These PCBs have higher circuitry density, higher connection pad density, and finer traces and gaps. Additionally, these PCBs are characterized by their smaller vias and capture pads, blind/buried vias, and through vias from surface to surface. HDI PCBs are largely chosen for enhancing the electrical performance of the device, and are finding their way into many applications including military communication devices, aerospace, computers, smartphones, and medical equipment, among several others. Being a leading HDI PCB manufacturer, we at Sierra Assembly Technology Inc. offer precision designed boards for use in high density applications. We have high tech capabilities and the right people to design advanced circuit boards to the exact customer’s specifications.
