AutomotivePCB

HDI PCBs

· High density interconnects to integrate more functionality.

· More routing layers, microvias and thinner dielectrics.

High Thermal Conductivity Dielectrics

· Dielectrics with ceramic fillers for improved thermal dissipation.

Low Temperature Co-fired Ceramic (LTCC)

· Multilayer ceramic PCBs for demanding RF and power modules.

Additive Processes

· Additive fabrication to produce high aspect ratio fine features.

· Technologies like aerosol jet printing.

Embedded Passives

· Passives like resistors and capacitors integrated within the PCB.
