Medical PCB Manufacturers: What They Do and How to Select the Best

Due to the COVID-19 pandemic, the global Medical Electronics market size is estimated to be worth USD 4506.3 million in 2022 and is forecast to a readjusted size of USD 5256.6 million by 2028 with a CAGR of 2.6% during the review period. Accordingly, the demand for medical PCBs is also increasingly growing. We can find PCBs in many medical devices such as diagnostic equipment, blood glucose monitors, ultrasonic devices, body temperature devices, fitness trackers, and so on. As a result, more and more PCB manufacturers have begun to enter the medical market, wanting a share of the pie. But unlike other PCBs, PCBs used for medical devices have very strict requirements, including extremely high precision and reliability. Hence, not every PCB manufacturer can be a good medical PCB manufacturer. In this blog, we will explain the services that medical PCB manufacturers can provide and offer workable suggestions about how to select the best medical PCB manufacturer for your projects.

Services That Medical PCB Manufacturers Provide

Generally speaking, medical PCB manufacturers can provide a full-scale of services, ranging from medical PCB designing, manufacturing to assembly and testing. There are many benefits of working with them including lower costs, logistical alignment, and rationalized supply chain management. They are well-versed in each step involved, making sure medical PCBs can play just the right role and help medical devices perform as expected.

Medical PCB Design and Manufacturing

Medical PCB Design and Manufacturing

Medical PCB manufacturers need to ensure a deep understanding of the needs of the project when designing, from function, material selection to product lifespan. The design must follow the standards and regulations of the medical industry, in addition, they also need to grasp the design trends of medical PCBs:

  1. Smaller and Denser

The component placement density for medical devices has increased as their circuit boards have become smaller. Subsequently, the board’s margin error has also decreased, imposing adaptability when manufacturing and designing these PCBs.

  1. High-Density Interconnect (HDI) Boards

Smaller boards that have advanced functionality cause paths with tighter interconnectivity and a small area for traces. Due to this, HDI is applied on many medical boards.

  1. Non-standard Form Factors

A non-standard PCB form factor designs have been brought by the latest trends that focus on self-monitoring health obligations for medical conditions, wellness, and exercises.

  1. Rigid-Flex Structures

Flexible electronics that must be incorporated with special manufacturing requirements while designing have continued to gain momentum.

To manufacture high-precision and high-quality medical PCBs, the production process must meet international regulations, and manufacturers should constantly optimize the fabrication process. For example, they can optimize the medical PCBs by right-first-time (RFT) manufacturing, and utilize the digital twin technology for PCB development that can identify potential errors before rolling the first board. By using these manufacturing methods, the fabrication cost would be reduced and the production efficiency would be improved significantly.

Medical PCB Assembly

Medical PCB Assembly

The medical PCBA is made by bonding electric components to a medical PCB. Several electric components must be assembled on a PCB for it to be effective in a device. Some of the factors the assembly process primarily relies on are:

The type that makes the circuit board classification

Features of the electric components assembled on the board.

Reasons for utilizing the circuit board

Below are popular assembly technologies used for medical PCB assembly:

  • HDI / via-in-pad technology

Via-in-pad technology helps to reduce about 50% space and improve component density on the PCB, so it is widely used for small medical devices. In addition, this assembly technology is suitable for PCBs that require high speed and high dissipation.

  • Surface Mount Technology 

Surface mount technology, also known as SMT, is an assembly technology that is used for almost all medical devices. It allows us to assemble more components even in a small space as the small size of SMT components. In addition, this assembly technology supports automated soldering and assembly that improve reliability and productivity.

  • Through-Hole Technology

Through Hole technology is a method that produces the electronic circuits in which the pin-through hole (PTH) components are installed through leads. It is actually a mounting process that inserts the leads into the drilled holes and solders the electronic components on the printed circuit boards.

Key Considerations When Selecting Medical PCB Manufacturers

It is not easy to find the best medical PCB manufacturer as there are a host of manufacturers in the market for your choice. Working with reliable manufacturers can shorten the project turnaround time and save costs, conversely, unqualified PCB manufacturers cannot catch up with the project schedule, and are hard to guarantee the quality of products. Then, here comes the question: How to select the best medical PCB manufacturer? Below are key considerations:

Quality and Manufacturing Standards in Medical Industry

Quality and Manufacturing Standards


The food and Drug Administration (FDA) classified the medical devices into 3 classes, each class refers to different types of medical equipment:

Class I Devices: General Controls

Class I medical devices consist of essential equipment like gloves, bedpans, and bandages that need sanitary, medical, and safety contemplations. Although these devices pose less to no safety hazards as they are not highly sophisticated, they still serve essential ends.

Class II Devices: Special Controls

These devices are a bit more complex than Class I devices, although they pose a higher hazard to users and patients. Class II devices include surgical needles, suture materials, and x-ray machines.

Class III Devices: Premarket Approval

Class III devices require approval from the FDA as they are more intricate than Class I or II devices. When manufactured inappropriately, these Class II devices can be more dangerous to users and patients. They include; heart valves, bone implants, and pacemakers.

At MOKO, all our finished medical devices that use our medical PCBA service are of Class II.


International Organization for Standardization (ISO) certifications are critical for medical PCB manufacturers.

ISO 9001: It refers to quality and reliability standards, manufacturers who get this certification can meet high standards in kinds of aspects including the design, fabrication, and testing processes.

ISO13485: This certification specifies requirements for manufacturers in the medical industry. It has strict requirements regarding the quality management system for the design and manufacturing of medical equipment.

Medical PCB Expertise

Medical PCB Expertise

Good medical PCB manufacturers have rich experience and are capable of identifying the manufacturability problem of your projects. They can offer workable suggestions to optimize the design, manufacturing, and assembly processes, which can also guarantee the smooth progress of each step involved.

Strict Testing Process

Reliable medical PCB manufacturers have strict quality control systems, they would perform testing at each step, and there are kinds of testing methods applied such as manual inspection, x-ray inspection automated optical inspection. Such strict testing processes can ensure that each piece of printed circuit board delivered to customers are of high quality.

Supply Chain Management

Good medical PCB manufacturers can offer supply chain management services, their quality management system makes it easy to trace and track each product, meanwhile, they have a stable relationship with suppliers that can shorten the lead time and reduce the cost significantly.
