- Design & Manufacturing Flexibility: Supports 1â10 layers, conductor thickness 0.5ozâ10oz, min 4/4mil line/space, and counterbore/countersunk holes.
- AutomotiveâGrade Reliability: Meets strict ADAS requirements for longâterm durability and functional safety.
These advantages make aluminum MCPCB the preferred substrate for high thermal conductivity MCPCB for automotive radar modules.
What are the Layout Key Points of 77GHz Radar MCPCB for Automotive ADAS?
Layout directly determines 77GHz radar sensitivity, accuracy, and stability. Below are critical rules.
- Impedance Control: Strict 50Ω impedance matching; tolerance ±5% for RF paths; controlled by line width, dielectric thickness, copper weight.
- Antenna & RF Routing: Antenna at board edge with 5â8mm keepâout zone; short, symmetric feed lines; avoid sharp bends; use GCPW for low loss.
- Grounding & Isolation: Solid continuous ground planes; via fencing/stitching around RF paths; separate RF/digital/power regions.
- Thermal Management: Dense thermal vias under heatâgenerating chips; direct thermal path to metal core; optimized copper distribution.
- Via Design: Use blind/buried vias to reduce stub inductance; laserâdrilled microvias down to 4mil; backâdrilling where needed.
- Manufacturing Tolerances: Min line/space 3/3mil (HDI); hole diameter ±3mil (PTH); outline tolerance laser +0.15/â0.05mm.
- Layer Stackup: Separate RF, ground, digital, power layers; multiâground for shielding and thermal conduction.
Following these rules ensures your 77GHz Radar MCPCB achieves consistent performance in mass production.
What are the Application Scenarios of 77GHz Radar MCPCB in Automotive ADAS Systems?
77GHz Radar MCPCB is widely used in core ADAS functions across passenger and commercial vehicles.
