Developing a wearable high-speed board with severe timing constraints

Stereo microdisplay controller. A Rigid-Flex PCB design for an Innovative Helmet-Mounted Display. The display’s physical requirements posed interesting challenges for the PCB.Timing was matching to a few picoseconds on the flight times through the board. With such tight margins, it was important to consider the travel time of flight inside the packages as well as on the board.
