What‘s Half hole PCB?

The half-hole Wi-Fi module PCB is the core circuit board for Wi-Fi modules. Half-holes are typically designed at the extreme edge of the PCB; half the hole is removed during routing, leaving the remaining half as a "half-hole".

The key lies in the edge "half-hole process"—precisely controlling half-hole depth, hole copper uniformity, and board-splitting stress. This ensures the edge half-holes enable miniaturization (50% less space than traditional connectors), stable 2.4G/5G high-frequency Wi-Fi transmission, and far better vibration resistance than standard interfaces.

Most modular PCBs adopt half-holes for easy soldering, small module size, and multiple functional requirements.

Benefits

• Ultra-Optimized Space

  Half-holes replace traditional connectors, reducing module thickness by 60% for a smaller overall size and meeting miniaturization design needs.

• Stronger Connection Stability

  Welding strength far exceeds plug-in interfaces, with enhanced vibration resistance, lower contact resistance, and more stable signal transmission.

• Signal Transmission Integrity
  

  Half-holes can be directly soldered to external antennas (e.g., ceramic antennas) or seamlessly connect to motherboard RF lines via board-edge half-holes, optimizing signal integrity.

Applications of Half-Hole PCBs

• Consumer Electronics: Used in motherboards for mobile phones, tablets, and TVs, as well as power supply, communication, and display modules. Its design enhances circuit connection and signal transmission, boosting product performance and stability.

• Automotive Electronics: Applied in automotive electronic control units (ECUs) like engine and body control units. Its high reliability and stability ensure normal operation of automotive electronic systems, improving vehicle safety and performance.
  
• Industrial Control: Used in control circuit boards for industrial automation equipment, including PLCs, frequency converters, and servo drivers. Its high-density wiring and stability meet signal transmission and circuit connection requirements, enhancing equipment accuracy and reliability.
  
• Medical Equipment: Applied in control circuit boards for medical devices such as ECG machines, blood pressure monitors, and ventilators. Its high precision and stability ensure device accuracy and reliability, improving medical diagnosis and treatment effects.
