In the past few decades, PCB has become smaller and smaller, and few industries can apply this more than the medical industry. Although this is the latest headlines, the electronic design of medical devices has not completely focused on reducing the size.

Buyers and their own end customers have seen much-needed performance improvements. How about it? High density interconnect (HDI) printed circuit board.

Today, electronic engineers have more reason to use medical pcb than ever before. As you will see below, the changing needs of the medical industry demand it!

What is medical pcb?

First thing: medical pcb can use advanced technology to integrate a large number of internal wiring to make it more compact. The new technology helps to reduce size without sacrificing performance, providing engineers with a variety of construction options based on application.

Medical pcb boards require additional manufacturing technologies, such as:

Next lamination

Stacked micropores

Interlaced micropore

Buried hole

Plated through-hole

Laser drilling

Why is high-density board crucial to medical technology?

Medical device manufacturers must meet the highest specifications, which means they consume the best HDI technology available today. There is also the problem of quality of life - the less invasive the device is, the earlier the patient will use it.

When you see implants, the most obvious is the demand for cutting-edge technology in the design of medical electronic devices. For example, pacemakers need to be small, light and reliable. High-speed transmission in medical pcb is a very ideal medical device, in which the response time of the device may mean life and death.

The need for smaller boards and better performance has led to the emergence of medical pcbs, allowing more components to be placed on each side of the original board. Designers can use increased I/O in a smaller space. The signal transmission speed is faster and the signal loss is less.

The design and manufacture of medical pcb is more challenging and costly, but the price is usually worth paying. Medical PCB assembly usually requires HDI technology, even if the cost of each board increases.

Medical pcb limitation

Each technology has its limitations, medical pcb technology is no exception.

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

Manufacturing HDI boards requires expensive equipment and expertise, and not every board manufacturer has it. The output is low because each circuit board requires more time to build. The multi-layer requirements of the circuit board are constructed with correct data to achieve the expected results.

This technology is relatively new and developing rapidly, so the situation of last year may not be applicable this year. You also have to figure out which of the six variants is best for your device - a difficult task without in-house expertise.

Medical pcb: want or need?

Compared with standard PCB boards, what we can do with medical boards now seems magical, especially those PCB boards with a long history. But this magic requires careful design and manufacturing, so your products are not just smoke swirling.

If you and your manufacturing partners can separate the correct medical pcb circuit board from the correct application, you will eventually get a smaller and more efficient circuit board. The peace of mind brought to patients will be more worthwhile than the increased cost.
