Fairfield Technology Limited focuses on early-stage product development including schematic design, embedded firmware, and the creation of functional prototypes. PCB layout services can also be provided where appropriate, with an emphasis on practical, well-structured designs suitable for validation and testing.

However, Fairfield Technology Limited does not specialise in production engineering, regulatory compliance (such as EMC), or volume manufacturing. Responsibility for ensuring that the final product meets applicable regulatory and certification requirements, including CE, UKCA, FCC, and related standards, rests with the client. This may involve further refinement, formal testing, and consultation with specialists in those areas.

While Fairfield Technology Limited does not offer compliance services, any potential concerns that arise during development may be flagged informally. If formal testing or certification is required, a qualified specialist should be consulted.
