Compact High Speed Design with Lukas Henkel
Lukas Henkel, CEO of OV Tech, discusses the design of high-density, open-source System-in-Package (SIP) modules and a Raspberry Pi Compute Module 4 (CM4) replacement called PyMix 8. He explains the engineering challenges of miniaturization, such as using standard PCB processes to manage costs versus moving to interposer-level packaging, and the strategic benefits of open-source hardware for supply chain resilience. The conversation also covers the use of open-source simulation tools like OpenEMS and Elmer for signal integrity and thermal analysis, visualized via FreeCAD and Blender.
