Electronic Interconnect Offering Medical Electronics PCBs
PCBs with special test needs.
Chicago, IL — Electronic Interconnect (EI) is now manufacturing specialized PCBs for medical device electronic assemblies and engineering and design services to help customers plan and develop medical electronic circuit assemblies. According to Pratish Patel, President and CEO, "Medical electronic assemblies have unique requirements that set them apart from other types of electronic devices, such as consumer electronic products."

"Often, thermal management issues must be anticipated in the design, and assemblers must conform to certain quality standards such as ISO 13485. Medical product manufacturers in many instances can benefit from the knowledge base and experience of PCB suppliers and industry players who have been through the many changes and advancements that the electronics manufacturing industry has been through in recent years."

For example, Patel says that burn-in and rigorous vacuum chamber testing are vital for medical electronics products. Testing involves subjecting fully functional sub-system circuit boards to different temperature cycles to ensure a full simulation, as though the product were fully operational in a medical facility. Vacuum chamber testing puts the subsystem circuit board in a real environment, with temperature ranges from -40 to +85°C for 24 to 48 hour test cycles, and it is put into non-stop operation for periods ranging from 24 to 72 hours. "Such a circuit board could be in a remote location with temperatures over 100°F, with no air control rooms or, at the other extreme, with temperatures below room temperature or below freezing temperatures" Patel says. "Thus, such environmental cycling exposes the PCB to possible anticipated extreme conditions, ensuring 100 percent product reliability as well as exposing latent defects."

To achieve high reliability goals, a sound product testing strategy must be created at the prototype stage, Patel adds. "That is when both OEM and EMS provider engineering staffs initially come together to discuss design and manufacturing objectives. In effect, the PCB prototype serves as a product R&D tool, allowing the EMS provider to increase reliability by defining and building in Design for Manufacturability (DFM) and Design for Testability (DFT) procedures within the different stages of the product development."
