Automotive PCB Design: How mechanical constraints for NEV smart cockpits shape the board's layout.
Hi everyone! I’m a researcher currently digging into technical documentation and localization strategies for New Energy Vehicles (NEVs). While analyzing user manuals for brands like BYD and NIO, I’ve become fascinated by the hardware that supports these "Smart Spaces".
I wanted to share this specific board from LHD TECH (where I'm doing my field case study). It's a great example of an automotive-grade, irregular-shaped PCB designed for a central dashboard unit.
A few technical highlights for discussion:
- Form Factor: The irregular shape is necessitated by the complex mechanical housing of modern EV cockpits.
- Reliability: To pass IATF 16949 and meet ASIL-D standards, these boards undergo rigorous thermal cycling and vibration testing.
- Layer Stack-up: With such high density, maintaining impedance control and signal integrity is a major challenge during the manufacturing process.
My question to the pros here: How do you usually handle the Ground Plane (GND) continuity in such irregular shapes to ensure EMC compliance? Looking forward to some technical insights!
