If you’re interested in PCBs for the medical industry, find out more about their main challenges and applications. Also, learn more about the core factors you’ll need to consider when designing medical grade PCBs and how we can help you.

Challenges of Medical Industry PCBs

PCBs for the medical industry must meet a few different requirements to ensure they’ll deliver the performance required. A few of the main challenges a PCB provider must be aware of when sourcing medical PCBs involve ensuring their PCBs meet compliance, size and reliability standards. Review some more information about the primary challenges PCB manufacturers must address with their PCBs below:

  • Compliance: One challenge for companies looking for medical devices is that they need to work with PCB manufacturers who can manufacture to Class 3 electronic requirements. Since medical devices and equipment fall under this class, a company with expertise in producing Class 3 electronics will be more likely to produce PCBs meeting compliance standards. PCB manufacturers must also keep detailed records, with lot tracking being especially important. Medical industry PCBs must also adhere to installation qualification, operation qualification and process qualification standards.
  • Size: Due to the trend of companies wanting smaller and smaller electronics, medical industry PCBs often have to have a miniature construction to fit in smaller medical devices. A good PCB provider will know how to properly craft tinier PCBs that still provide top-tier performance.
  • Reliability: Since medical equipment outfitted with PCBs is often used for lifesaving purposes, they need to be reliable. Medical devices and the PCBs in them are often exposed to extreme temperature, liquid and shocks. Due to this possible exposure, medical PCBs must be able to work in potentially dangerous environments and deliver reliable results.

Factors to Consider When Designing Medical PCBs

Factors to Consider When Designing Medical Grade PCBs

As you look for the right PCBs materials and specifications for your medical equipment and devices, you’ll have many different options to consider. By selecting the right PCB specifications for your medical device, you can receive the best performance possible. Check out some of the main PCBs used in the medical field and some of the top factors that make particular PCBs a good choice for certain applications below:

  • Flexible PCBs: Flex PCBs are a top choice for many medical devices. Since medical devices are often placed in locations requiring flexibility, the malleable nature of flex PCBs makes them a great option. When a medical device will be folded and wrapped, turn to flex PCBs.
  • Flexible aluminum PCBs: While flex PBCs are appropriate for many electronic medical devices, some high-power devices need a more powerful PCB. Flexible aluminum PCBs are perfect for high-power applications as they feature heat transfer qualities. Some top applications for these boards include scanning and surgical lighting applications.
  • PCB microcircuits: Another factor you might want to consider is whether you want to utilize flexible PCB microcircuits. Like flex PCBs, PCB microcircuits are malleable, but they separate themselves by allowing you to utilize even smaller PCBs with greater performance. Due to their design, PCB microcircuits are often used in small medical devices, such as industrial sensors, wearable technology and hearing aids.
  • Polyimide PCB material: As you look for the right base material for your PCB, polyimide is often a great choice. Polyimide PCB materials feature excellent tensile strength and flexibility. These materials are also highly durable, very thermally stable and chemically resistant, making them perfect for some medical devices, such as prosthetics and implants.
  • Ceramic PCBs:Ceramic PBCs are a great choice for organizations using medical devices with circuits featuring a low coefficient of thermal expansion and high thermal conductivity. These PCBs can operate in extremely high temperatures, provide incredible high-frequency performance, easily implement high-density tracing and offer tough chemical erosion resistance.
  • Rigid-flex PCBs: A rigid-flex PCB combines the benefits of flex circuits with the durability of rigid PCBs. The flexible materials sit in between rigid layers with conductors and are plated through holes to link them with other layers. These boards offer more durability than flex boards without the weight and size of rigid boards, presenting more design versatility. They’re common in applications like consumer electronics, lighting, contract manufacturing, instrumentation and more.

Our Capabilities

At MCL, we regularly help engineers and designers of medical instrumentation by providing complete medical device PCB fabrication and engineering support to bring your product to life. Our ability to generate high-frequency and high-density interconnect PCBs can be applied to medical devices.

Find out more about how our PCB capabilities can help you go from concept to market below:

  • Prototyping: When you have a new product or design revision, MCL can help by providing you with PCB prototypes to test the design and PCB prior to going into production.
  • Engineering support: Our team at MCL regularly provides engineering support services to customers, consulting with them to ensure PCB specs fit the budget and end application. Some of our top engineering solutions include Design Rule Check, Design for Manufacturability, cost consulting, stackup design, surface finish consulting and laminate and raw material considerations. All of these services mean we can help you craft PCBs to meet both your financial and quality needs.
  • Fabrication: Alongside helping our customers by giving them engineering solutions and prototypes, we can oversee the fabrication process. Since the PCB manufacturing process is complicated, we have long-standing, strategic partnerships with domestic and overseas PCB facilities capable of providing our customers with high-quality products at an affordable rate. Boards are always produced by a best-fit factory for the type of PCB, complexity, and technology involved.
  • Lifecycle: Once your PCB has gone through the engineering and fabrication processes, you can still expect MCL to help you once your PCB hits the market. Since we’re committed to assisting you throughout your entire PCB’s lifecycle, we’ll be there for you after a sale if your has PCB any issues or needs analysis. We also put any PCB we sell through several quality assurance measures to minimize the risk of future PCB issues. MCL is able to manage customers revisions to the board so our customers don’t have too.
