HDI PCB in medical equipment

In the past few decades, PCB size has become smaller and smaller, and PCB engineers have more reasons to use HDI PCB than ever before.

Why is high-density board important to medical technology?

Medical equipment must meet the highest standards, which means the best technology currently available. The quality of life is also problematic-the less invasive and invasive the device, the earlier the patient will use it.

When we look at implants, the most cutting-edge technology needs in the design of medical electronic devices are most obvious. For example, pacemakers need to be small, light and reliable. High-speed transmission in HDI PCBs is ideal for medical devices, where device response time can mean life or death.

The demand for smaller circuit boards and better performance results in HDI PCBs requiring more components to be placed on each side of the original circuit board. It needs to be in a smaller space, so that the signal transmission speed is faster and the signal loss is less.

HDI PCB is more challenging and expensive in design and manufacturing, but usually the benefits are worth it. Medical PCB assembly usually requires HDI technology, even if HDI costs increase.

Limitations of HDI PCB

Each technology has its limitations, and HDI PCB technology is no exception.

For most medical equipment manufacturers, the biggest limitation of HDI technology is its cost.

Manufacturing HDI boards requires expensive equipment and expertise, and not every board manufacturer has them. Since each board requires more time to build, the yield is lower. The correct materials need to be used to construct the multiple layers of the circuit board to achieve the desired results.

This technology is relatively new and developing rapidly, so what happened last year may not be the case this year.

HDI PCB: Is it necessary or not?

Compared with standard PCB boards, HDI PCB has better improvements in radio frequency interference, electromagnetic wave interference, electrostatic discharge, and heat conduction. If you and your manufacturing partner can combine the right HDI board with the right application, you will end up with a smaller and more efficient board. It will be worthwhile to bring more safety and convenience to patients.
