Evolution of Medical PCB Assembly
There is more to the advancement of technology and medical devices, and people may no longer need the services of hospitals and doctor’s offices. Medical PCB services are a result of evolution that makes medical operations easier and more stress-free. Diagnosis is one of the key steps to fully utilize these electronic devices to minimize treatment time and increase treatment efficiency.
PCB assembly in the medical field introduced better versions of X-ray, ultrasound, MRI, and medical imaging machines, followed by premium CT scanners. There are even life-saving devices that monitor diseases and provide treatment, therapeutic services, and life support.
The cumbersome procedures behind medical PCB assembly
In order to facilitate the use of specialized electronic devices by customers, medical PCB manufacturers must go through a comprehensive planning, preparation, and execution process. They first create a concept, then conduct research circuits and printed circuit design, manufacturing, prototyping, design review, and most importantly, quality inspection. PCB design, prototyping, and packaging are often critical stages because they determine whether the PCB assembly is feasible.
A printed circuit board assembly or PCBA is a combination of multiple components that are assembled together in a specific order to form an assembly. M4edical PCB is a circuit board customized for medical devices.
Manufacturing is the next important stage to ensure that the product is completed. Once the design is completed, the manufacturer must convert it into a product shape, but before that, prototyping is necessary because it will guide the appearance of the product. Medical PCB manufacturers must demonstrate capabilities by understanding the design before starting work. In addition, they must follow the strict measurements provided and then follow some specific requirements such as liquid resistance, etc.
Technologies Used in Medical PCB Assembly
The medical industry is proudly using the following technologies to provide the best to its patients:
Via-in-pad/HDI technology: As the name suggests, vias are inserted into the copper pads to save space on the printed circuit board. With the in-pad technology, the space of the PCB is larger than the older versions.
The in-pad technology became well-known once it was invented due to the demand for smaller electronics and pitch devices. While buried and blind vias also help save space and increase component density, nothing has proven to be more effective than via-in-pad. They have a proven skill in making PCBs run efficiently.
SMT or Surface Mount Technology: All medical PCB manufacturers use SMT to manufacture commercial devices, providing a ton of advantages to the users. Even more, the technology allows packing more items in a limited space, followed by PCB assembly and automated soldering to save costs and improve reliability.
PCB Pitch and Fine Lines: The latest generation of electronic devices completely relies on high-density interconnect technology, especially pitch and fine lines. It offers advantages over other traditional technologies, namely enhanced wiring, cheaper manufacturing costs, and smaller board sizes.
Medical Devices Assembled Using PCBs
In fact, more than half of all medical devices currently available in the market are using PCB technology. Thanks to the efficiency and productivity gains of PCB technology, medical implementation has become easier and less laborious for both doctors and patients.
Some of the medical PCB devices worth considering include:
Implantable Medical Devices: Implantable medical devices are complex components of implantable medical devices that operate under completely different standards compared to other PCBs. The reason behind this is the delicate implantation needs, and the expectations that come with them. These medical devices include:
Cochlear Implants: Process sounds and provide hearing aids.
Implantable Defibrillators: Designed to protect people from heart problems caused by sudden trauma.
Responsive Neurostimulators or RNS: Designed to treat brain problems, especially epilepsy.

Importance of Surface Mount Technology (SMT) in Medical Devices
Many medical PCB manufacturers use surface mount technology to place circuit components directly on PCBs. The end product is called a surface mount device or SMD because it can be simply mounted on a flat surface. Unlike the current traditional procedures, SMT works with leaded or footed components that pass through holes in the PCB and then undergo a soldering process.
The biggest advantage of SMT is the ease of automation. Manufacturers have found that surface mount automation is easier than soldering tiny holes that are not always ready at present. Apart from this, the following factors give SMT an edge over other methods:
More cost-effective compared to PCBA through-hole method
No need to make many holes, so drilling is less frequent
Components can be placed on either side of the board
Surface mount technology components are smaller in size and take up less space than traditional leaded components
SMT has better density than traditional parts
The productivity and efficiency of SMT is much higher than PCBA, especially when dealing with constant motion and vibration
Important Decision – Reliable Medical PCB Manufacturer
In addition to focusing on medical devices, another factor worth considering is choosing the right medical PCB manufacturer, who must have a wealth of knowledge and professionalism to design reliable medical devices.
It is quite difficult to find a large list of circuit board manufacturers, but the most important thing is their productivity and other capabilities. Each PCB manufacturer has a different set of services that customers must identify and make choices accordingly.
Generally, the following points play a key role in selecting the right medical PCB manufacturer:
