Medical PCB Manufacturing & Assembly

Medical PCB Manufacturing & Assembly for Devices, Instrumentation, & Equipment

One-Stop Fabrication & Assembly

Medical devices have one crucial requirement - 100% reliability. When a patient’s health and life are at stake, nothing less than perfect functionality without failure is acceptable.

To achieve this level of reliability, your PCB manufacturer and assembly partner needs to meet and understand the various strict medical standards.

Medical standards have been in place for decades to guide the robustness and safety requirements of electronic designs. These standards are strict and can be challenging to meet so it’s important to verify your boardhouse’s credentials and protocols.

Standards & Guidelines for Medical Devices

The largest governing bodies publishing medical device regulations are the IEC and the ISO. In addition, the FDA and FCC may also have their own standards. There are several different standards that are all necessary due to the broad scope a medical device may fall into.

NIST LogoITAR Compliance Seal  IPC International, Inc. Membership Seal SAM

San Francisco Circuits has provided medical PCB manufacturing and assembly that have adhered to many standards for different uses. Typically, all medical devices will be compliant with ISO 13485.

ISO 13485: ISO 13485 is used by organizations involved in the design, production, installation and servicing of medical devices. ISO 13485 is the FDA’s mandatory quality management system (QMS) for medical devices.

Best Practices for Medical Device PCB Layouts

It’s always best to follow good practices with PCB layout to prevent board-level faults. In the case of medical devices, lives are dependent on the successful operation of the PCB, so following best practices is not just recommended, but essential.

Some of the best practices for medical PCB devices include:

  • Keep trace lengths and sensitive signals as short and direct as possible
  • Use power planes and ground planes to shorten decoupling capacitor signals and provide good ground coverage
  • Build in enough copper for high power dissipation and minimized voltage drop for high energy traces/planes
  • Use differential pairs/signals for high speed data traces to minimize reflection
  • Keep clock signals very short and separate from other nearby traces/planes to prevent cross-talk
  • If you have to overlap traces from different layers, do it as perpendicular as possible
  • Isolate temperature sensitive components from other components
  • Always double check reflow soldering requirements to make sure that some components aren’t having their max temperature exceeded during assembly

Testing Procedures for PCB Medical Devices

In addition to the design process, there must be many stages of testing including:

  • Life tests (which may need to be “accelerated” depending on the application)
  • High impact testing
  • Water submersion
  • EMI/ESD tests
  • Any other harsh environmental testing that may be relevant to the application

And for PCB-specific tests, here are few important tests:

  • Bare and functional level testing
  • Power testing
  • RF tests/tuning
  • Differential pair testing/optimizations
  • X-ray inspection for non-visible solder joints

Though verification and validation tests may reveal some issues upfront before launch, failures in the field can be devastating. Thus, it’s best to increase overall confidence, test as thoroughly as possible, and to re-visit the risk assessment to make sure that each potential hazard has been addressed and tested against.

Via tenting is the application of soldermask to encase or seal the via’s opening. A via is essentially a hole drilled into the PCB that facilitates connections between multiple PCB layers. An untented via, on the other hand, remains uncovered by a soldermask layer. The decision to expose or cover these vias carries both advantages and disadvantages contingent upon your specific design and manufacturing requirements.
