About Electuni LLC
Electuni LLC is an electronics development company registered in Wyoming (USA), founded in 2016 by Niloy Mondal, who has served as CEO and Lead Hardware Engineer (IPC CID and CID+ certified) since 2018. The company develops complete hardware products: system architecture, schematics and PCB layout in Altium Designer (including HDI, RF and impedance-controlled routing), embedded firmware for ESP32, STM32 and Nordic nRF from bare-metal to Zephyr RTOS, 3D enclosure design in SolidWorks with thermal simulation and injection molding preparation, as well as IoT systems with cloud connectivity (AWS IoT, Azure, MQTT, TimescaleDB, Grafana) and companion apps in React Native and Next.js. A dedicated PCB design division operates under circuit-board-design.com. Since 2016, more than 500 PCB designs have been delivered and over 500 production boards shipped; an MVP can be developed in 12 weeks. The company is listed as a verified supplier on the SAP Ariba Network, PCB Directory and GoodFirms, and works with product teams in the USA, UK, Germany, the Netherlands, France, Austria and Australia.

Materials & Design Focus
FR-4
Standard base material for PCBs, also for impedance-controlled designs with tuned stackups.
ABS
Cost-effective, impact-resistant plastic material for injection-molded enclosures, typical in the consumer sector.
Polycarbonate (PC)
Higher impact strength and heat resistance than ABS for more demanding enclosure applications.
Aluminum
For enclosures requiring thermal conductivity, EMI shielding and stiffness, among others in 3D enclosure design.
