An HDI PCB, orHigh-Density Interconnect PCB, is a circuit board with finer traces, smallerspaces, microvias and higher connection density than a conventional PCB.
HDI technology allowsmore electronic components and electrical connections to fit into a smallerboard area. It is suitable for compact, lightweight and high-performancerobotic electronics.
HDI PCBs supportcomplex circuits and high-density component assembly while reducing board sizeand signal-path length.
Depending on thedesign, they can provide:
High-speed data processing
Power and signal distribution
Fine-pitch BGA component support
High-density sensor connections
Controlled-impedance signal transmission
Compact system integration
Improved signal integrity
Antfield HDI PCBs canbe used in:
Robot main control boards
AI computing and edge-processing modules
Camera and machine-vision systems
Sensor fusion and navigation boards
Motor and joint-control modules
High-speed communication boards
Humanoid robots and robot dogs
Industrial robots, AGVs and service robots
Higher circuit density
Smaller and lighter PCB designs
Support for fine-pitch components
Shorter signal paths
Improved signal integrity
More efficient use of board space
Suitable for advanced multilayer designs
Helps reduce the size of robot electronic modules
HDI PCBs can becustomized according to project requirements, including:
1+N+1, 2+N+2 and multilayer HDI structures
Blind and buried microvias
Stacked or staggered microvias
Via-in-pad technology
Laser-drilled microvias
Fine-line and fine-space designs
Controlled impedance
ENIG and other surface finishes
Prototype and volume production
Reliable HDI PCBmanufacturing requires careful attention to:
Layer stack-up
Microvia structure
Via aspect ratio
Pad and trace dimensions
BGA pitch and breakout design
Impedance and signal integrity
Copper balance and thermal management
Material selection
Manufacturing tolerances
HDI design requirementsshould be reviewed before production to balance electrical performance,reliability, manufacturability and cost.
Antfield reviews HDIPCB production files and technical requirements before manufacturing. Qualitycontrols can include:
DFM and stack-up review
Material and copper-thickness verification
Microvia and via-in-pad inspection
Hole and layer-alignment checks
Controlled-impedance testing
Electrical continuity and isolation testing
Surface-finish inspection
Cross-section analysis when required
Final appearance and dimension inspection
Production records and traceability
Antfield providescustom HDI PCB manufacturing and assembly services for robotics, supportingprojects from prototype verification to volume production.
