Electrical Engineering Services

Electro-mechanical and connected medical devices improve patient experience and quality of care. Therefore, Neuma partners with its customers to get products to market quickly and successfully. Through a Design for Production (DFP) approach we focus on producing innovative solutions created with the foresight of commercial scale to avoid the delays that plague many programs as they move from prototype to high volume production.

Our Electrical Engineering Skillsets

Our team has a wealth of experience in designing electro-mechanical devices, connected devices and test equipment. We excel at all the stages of product development from customer engagement, planning and requirements gathering to handover and post-handover support including concept development and design strategy, prototyping and design realization, and design iteration and enhancement. Some of our capabilities include:

  • Understanding and definition of critical customer requirements, timelines and deliverables

  • Requirements traceability to system requirements

  • Capture of specific usability requirements for User Interface (UI) components

  • Preliminary component selection and technology approach

  • Consideration of external requirements such as regulatory (FDA, CE) and international electrical safety standards applicable to the type of device being designed

  • Hardware specifications generation detailing expected design performance criteria

  • Impact analysis of component selection on supply chain (long lead time parts, end-of-life considerations

  • Analog and digital circuit design (including widely-used microcontrollers such as the STM8 and MAXIM 32660 (Cortex-M4) based devices)

  • Rapid Arduino prototyping of digital control circuits

  • Bus technologies including GPIO, SPI, I2C, async serial communication

  • Motor control (stepper, servo and brushed/brushless motors)

  • Low power (battery-operated) wearable technologies

  • UI technologies (displays, keypads, switches, annunciators)

  • Sensor interface/integration including magnetic proximity and optical detection technologies

  • Through hole, surface mount and multilayer printed circuit board topologies

  • High density PCB layout

  • Circuit behavior prediction from design inputs including system, electrical, regulatory and safety requirements

  • Schematic capture and PCB layout using Altium Designer, our preferred PCB design tool.

  • First article bring-up and evaluation

  • Hardware integration with firmware, and programming/testing PCBAs

  • Board manufacturer liaison to resolve issues

  • ETL electrical safety testing support to applicable standards (in conjunction with a 3rd party test body such as Intertek)

  • Test reports to support regulatory submissions

  • Component selection, tolerance analysis and component end-of-life review

  • Failure Mode Effect Analysis (FMEA) based on the electrical design

  • Risk Analysis and Risk Management Planning associated with electrical design tasks

  • Hardware and firmware debugging and incremental design change to address specific areas where specifications are not met

  • Data collection from operational prototypes

  • Contract manufacturer liaison service for design transition to production
