Electronics Design
PCB development carries inherent risk — long lead times, manufacturing costs, and the possibility that initial designs won't meet specifications. High-speed digital interfaces, mixed-signal architectures, and RF integration require attention to detail that extends beyond standard schematic capture and layout practices.
Dagny Labs provides electronics design services informed by experience across defence radar systems and commercial instrumentation. Thorough design validation — comprehensive datasheet review, detailed power and temperature analysis across operating windows, careful consideration of layout requirements before fabrication — reduces the likelihood of respins.
Experience spans microcontroller and embedded systems through complex FPGA SoCs with integrated data converters. High-speed digital design includes DDR memory interfaces with proper termination and timing closure, multi-gigabit serial links requiring eye diagram optimisation, and standard networking interfaces. Mixed-signal capabilities cover HF through UHF RF design, precision analog circuits, and discrete data converter implementations. Design services include schematic development, detailed layout guidance, component selection for reliability and lifecycle, and adherence to relevant standards (MIL-STD, IPC, EMC compliance).
Services range from complete PCB design through manufacturing to design review and hardware debugging. Design for manufacturability is emphasised — verifying fabrication capabilities upfront, configuring CAD rules appropriately, and ensuring assembly processes are validated before volume production.
Practical limits exist around GHz-range layout complexity and specialised domains like millimetre-wave design or high-power supply engineering.
Industry Experience
Electronics development across defence and commercial sectors provides practical understanding of what separates prototype demonstrations from production-ready designs. Systematic validation of design decisions against real-world constraints — manufacturing tolerances, thermal performance, power integrity, EMC margins — is the discipline.
Whether the requirement involves mixed-signal integration, high-speed digital design, or troubleshooting existing hardware, the focus remains on methodical engineering that manages technical risk while meeting project timelines and cost objectives.
