Little knowledge - Medical Devices
Electronics contributes significantly to today's health-care industry like in diagnostic, monitoring and treatment devices. Because of the health implications associated with them, medical PCBs are held to higher standards than most other PCB types.
PCBs within the medical industry are highly specialized to satisfy the restriction of medical devices. In many medical applications, requirements like size and appearance are existed for an implant or emergency room monitor. For this reason, medical PCBs tend to be specialty high-density interconnect PCBs (HDI PCBs) or made with flexible base materials, allowing PCB to flex during use.
