As consumer demands change, so must technology. By using HDI technology, designers now have the option to place more components on both sides of the raw PCB. Multiple via processes, including via in pad and blind via technology, allow designers more PCB real estate to place components that are smaller even closer together. Decreased component size and pitch allow for more I/O in smaller geometries. This means faster transmission of signals and a significant reduction in signal loss and crossing delays.
What is the usage of HDI PCB?
A HDI PCB is usually found in complex electronic devices that demand excellent performance while conserving space. Applications include mobile /cellular phones, touch-screen devices, laptop computers, digital cameras, 4/5G network communications, and military applications such as avionics and smart munitions.
Automotive and aerospace industries, where lower weight can mean more efficient operation, have been utilizing HDI PCBs at an increasing rate. Like almost everything else, cars are becoming more connected and computerized. Today’s cars have around 50 microprocessors on board that play a role in engine controls, diagnostics, safety features and other conveniences. Many advanced features such as onboard WiFi and GPS, rearview cameras and backup sensors rely on HDI PCBs. As automotive technology continues to advance, HDI tech will likely play an increasingly important role.
HDI PCBs are also prominently featured in medical devices; advanced electronic medical devices such as equipment for monitoring, imaging, surgical procedures, laboratory analysis etc., incorporate HDI boards. The high-density technology promotes improved performance and smaller, more cost-effective devices, potentially improving the accuracy of monitoring and medical testing.
What are the applications of HDI PCB?
The HDI PCB is making an impact on the medical industry. The medical devices are usually HDI since they can fit in small devices like implants and lab and imaging equipment. Medical equipment plays a crucial role in diagnosing diseases and also do provide life support. Ex: Pacemaker, Diagnostic and monitoring facilities.
Car manufacturers are extremely attracted to small-sized PCBs since they can save more space in the car. With the launch of futuristic cars from brands like Tesla, the integration of the electronic devices to provide a better driving experience has been the prime focus of the carmakers.
