What Is a Medical PCB ?

Medical PCB is a type of PCB that’s used to make medical equipment and facilities. Medical equipment and facilities must be accurate and precise due to the sensitive nature of medical fields. It’s primarily because using these equipments and facilities on people puts their lives at risk. It is essential that medical equipment be built using reliable and precise medical PCBs in order to provide accurate and reliable results.

Technologies for Medical PCBs

The current trend in electro-medical devices is to create smaller products with a higher density of components, as has been the case in other electronic fields. There are many implications for printed board design as a result of this. These include the arrangement of components, their relative distances, length and distance between traces, as well as thermal dissipation. The margins of error for designing a board have decreased dramatically, which often means that need greater flexibility during design and production.

This need can be met by PCB technology that allows for the creation of high-density connection boards (HDI). The area for routing the traces is reduced by reducing the PCB’s size and increasing the complexity of the functionalities.

Flexible and rigid-flex printed circuit board technology is another popular technology used in medical PCBs. Medical devices are often not the standard size and shape of traditional PCBs. They must fit in the smallest area possible, which ensures the same reliability and durability. Flexible PCBs can be made of lighter materials to reduce the overall device’s weight. These PCBs can bend to optimize space and reduce production costs. This gives the designer more flexibility in designing the case. Even though the design of a flexible computer board is more complicated than a rigid one, it’s much easier to create a robust and ergonomic device.

Flexible PCBs have significant mechanical advantages over rigid ones in many medical applications, particularly wearable ones. Flexible PCBs can also be connected to rigid boards using thin flat cables without the need for bulky connectors.

Many wearable devices are now using non-standard PCB forms. This is a result of the current trend in many devices that monitor vital signs, such as those for training, fitness, or clinical purposes. Sometimes, the PCB may take on completely different shapes. Designers can easily design printed circuit boards with a variety of shapes and sizes by integrating flexible and rigid-flexible PCBs.

Primary Use PCB Boards in the Medical Industry

There are many options when it comes to selecting the right PCB specifications and materials for medical equipment and devices. You can get the best performance for your medical device by choosing the correct PCB specifications. Below are some of the most important PCBs in the medical field. Also, you can see the top factors that make certain PCBs suitable for specific applications.

Flexible PCBs

The FlexPCBs are the top choice for many medical devices. Flex PCBs are a great choice because they can be bent to fit in places that require flexibility. Flex PCBs are great for medical devices that will need to be wrapped and folded.

Flexible Aluminum PCBs

Flex PCBs can be used for many electronic medical devices. However, certain high-power devices require a stronger PCB. Because they have heat transfer properties, flexible aluminum PCBs can be used for high-power applications. These boards are ideal for scanning and surgical lighting applications.

PCB Microcircuits

In addition, you might want to consider whether flexible PCB microcircuits are right for your project. We know that they are malleable like flex PCBs and offer greater performance, at the same time, the PCB microcircuits can be used with smaller PCBs.

On account of the unique design of PCB microcircuits makes them ideal for small medical devices such as hearing aids, industrial sensors, and wearable devices.

Polyimide PCB Material

When you are looking for the best base material for your PCB board, Polyimide is a good choice. The flexibility and tensile strength of polyimide PCB substrate materials are outstanding. Since the materials are extremely durable, thermally stable, and chemically resistant, making them ideal material for medical devices like prosthetics or implants.

Ceramic PCBs

These Ceramic PCBs make a great choice if you use medical devices that have low coefficients of thermal expansion and high thermal conductivity. These PCBs are capable of operating at extremely high temperatures and can provide exceptional high-frequency performance. They also allow for easy implementation of high-density traceing and resist chemical erosion.

Rigid-flex PCBs

A rigid-flex PCB offers both the flexibility of circuits and the reliability of rigid PCBs. In order to connect the flexible materials with other layers, the flexible materials are plated through holes between rigid layers with conductors. These boards are more durable than flex boards and offer greater design flexibility. These boards are used in many applications, including consumer electronics, lighting and contract manufacturing, instrumentation and more.

Medical PCB What Is Traceability

It is a invaluable asset to be able to track your steps. This allows you to look back at past practices and have an idea of what the outcome will be. This hindsight can only be useful if it contains data or information that identifies areas for improvement or actions. It is possible to define traceability as follows for circuit boards and electronics:


For PCBA development, traceability means that raw materials and components, as well as the equipment and processes (including inspection and validation techniques), which utilize them throughout the manufacturing process are tracked and documented through specific data, such as product serial numbers.

It is important to consider three primary aspects of traceability in the medical industry when developing PCBAs and electronics:

Quality Management

The ISO13485 standard is an international agreement for all medical device suppliers and OEMs. This standard must be adhered to by all suppliers of medical devices to companies or organizations. The OEM may require other links in the supply chain to comply with the requirements of this standard, such as those that supply components, materials, and maintenance.

Process Agility

Manufacturers can develop and implement an effective risk management plan by following the PCB traceability requirements. It is also an internationally acknowledged standard, ISO 14971, which provides a comprehensive framework for managing risk. Among the templates available are Preliminary Hazard Analysis (PHA), Hazard Analysis and Operatability studies (HAZOP), Failure Mode Analysis and Effect Analysis. Having these strategies in place will help you improve the reliability of your product development process.

Legal Responsibilities

Another reason to comply with PCB traceability requirements regarding medical devices is to provide legal protection in the case of an emergency that could result in harm to patients or other significant damages. In such situations, it can be extremely valuable to show your compliance with industry standards.

Considerations When Designing and Assembling Medical PCBs

● Consistency: The primary requirement for a Medical PCB, is that it provides reliable output every time it is used. Due to its potential for affecting human life, precision is crucial when designing a medical PCB.

● Safety: Some medical devices can be worn or implanted as tiny circuits. The medical PCB design must protect the patient from any vibrations or extreme temperatures.

● Convenience: User-friendliness in Medical PCB Design is a key factor. It is important has to take into account the product’s easy accessibility as well as its durability.

● Lifespan: The efficient design of power and on-board batteries is essential to prolong the equipment’s lifespan. The device’s lifespan can be improved by understanding the common failure points and designing a sturdy product.

All of these factors can be addressed by adhering to the regulations and medical PCB standards.

Assembling Medical PCB

The next step after designing and fabricating a PCB is assembly. The PCB assembly involves soldering various electronic components onto the fabricated board. Since an assembled PCB board can function to achieve its intended purpose, this procedure is performed to test the bare PCB whether functions as intended.

You should consider some important factors before assembling PCBs. These important factors include the type and function of the PCB, as well as the characteristics of its parts. When it comes time to assemble the circuit board, you will need some essential tools. You will need testing equipment, soldering machines, and SMT equipment to assemble. Solder paste and solder wire are also important materials.

It is extremely important to perform a design-for-manufacture test before you start assembling the board. It is necessary to test the design for manufacturability before you begin assembly in order to identify and resolve any design issues. DFM’s main objective is to ensure that the final medical circuit board functions as expected after assembly.
