Electronics & PCB Design
Electrical engineers bring intelligence, power, and connectivity to products.
Diatomic provides world-class PCB design and system-level electronics design services for hardware-based products, including medical devices, scientific instruments, and connected IoT systems. Our Seattle-based engineers design production-ready electronics that integrate seamlessly with mechanical systems, embedded firmware, and user interfaces. Our team can take your idea from concept to reality with turn-key solutions.
We deliver expertise across analog, digital, mixed-signal, and power electronics, with deep experience in low-noise sensing, wireless communication, battery management system and embedded hardware architecture.
From compact consumer devices to complex medical instruments, we create reliable, manufacturable electronics that deliver performance, efficiency, and compliance across every stage of development.
Our approach unites engineering rigor and cross-disciplinary collaboration to deliver electronics designs that are technically refined, manufacturable, and ready for market success.
Key Activities
System Architecture & Technology Development
We begin by defining the product’s electrical architecture. This includes mapping processors, sensors, power systems, and communication interfaces into a cohesive design. In the case of products based on new or novel technology, we use subsystem prototypes to test emerging technologies and novel features to prove feasibility and reduce technical risk early in development. Early collaboration across mechanical, firmware, and industrial design teams ensures that size, performance, and regulatory requirements are aligned from day one.
- System-level block diagram and power-budget definition
- Processor, PMIC, memory and sensor selection
- Software architecture and interface definition
- Processor (MCU) selection and integration
- Communication interface design (BLE, Wi-Fi, CAN, Ethernet)
- Batteries, battery management systems and power supplies
- Displays, communication protocols and optical systems.
- Wireless and ultra-low power rechargeable systems.
- Signal conditioning and analog front-end circuits
- EMC and safety considerations from the start
Detailed Circuit Design
Our engineers develop detailed schematics and perform circuit simulations to verify function and performance before hardware is built. Component selection, power regulation, and signal-integrity design are optimized for reliability, cost, and availability. Every subsystem, from battery management to wireless connectivity, is carefully engineered for robust operation.
- Analog and digital circuit design
- Mixed-signal and low-noise design for sensors
- Power regulation and efficiency optimization
- System Simulations and Timing Analyses
- Thermal instrumentation and control
- Design of complex FPGA-based systems
- Schematic Development, Gerber and Netlists
- Design reviews and failure-mode analysis
- Power optimization and battery management
PCB Layout & Integration
We transform schematics into high-density printed circuit board (PCB) layouts that meet electrical, mechanical, and electromagnetic requirements. Working in close coordination with mechanical and manufacturing teams, we ensure thoughtful electronics integration and precise component placement, thermal management, and manufacturability.
- Multilayer PCB design for compact form factors
- Multisided, rigid, flex, and rigid-flex PCBs
- High-speed routing and impedance-controlled signals
- RF layout and antenna integration
- Optimization for manufacturing and testing
- Close collaboration with hardware team
Prototyping & Validation
Prototypes bring circuits to life. We assemble and test early board designs to validate performance, debug interfaces, and fine-tune power, timing, and signal characteristics. This iterative phase bridges hardware and firmware integration, reducing risk before production.
- PCB bring-up and hardware debugging
- Power and signal verification
- Firmware integration testing
- Thermal and environmental testing
- Early compliance and safety tests (FCC, UL)
Verification & Compliance
We verify that every design meets functional and regulatory requirements through rigorous testing. Including EMC/EMI, electrical safety, thermal cycling, and reliability testing. For medical devices, we follow IEC 60601-1, ISO 13485, and FDA design-control practices to ensure full compliance and traceability.
- EMC/EMI pre-compliance and certification
- Electrical safety and isolation testing
- ESD and surge protection validation
- Environmental stress and lifetime testing
- Compliance documentation
Manufacturing Transfer Support
As products transition to production, our engineers develop factory test procedures and support pre-production builds. This includes release of manufacturing documentation, test procedures, production programming support, and coordination with contract manufacturers to ensure smooth production ramp-up.
Electronics design sits at the intersection of hardware architecture, embedded firmware, and system integration. Our electrical engineers work closely with mechanical, firmware, and industrial design teams to create cohesive, fully integrated products.
We deliver electronic systems that are efficient, safe, and manufacturing-ready. By integrating system design, circuit development, and manufacturing support, our electrical engineering team helps bring innovative products to market.
