Xentronics is an electronics design and manufacturing consultancy based in Melbourne, Australia. Our team of highly skilled hardware and firmware engineers provides comprehensive “one-stop-shop” solutions for the entire product lifecycle. From initial concept through prototyping, risk mitigation, compliance testing, and production, to end-of-life replacement and upgrades, we support every stage of your project.

Rather than focusing on a single area, we apply a diverse skill set across multiple electronics disciplines to deliver disruptive, cost-effective, and high-quality products. Our key capabilities include:

• Power Supplies
  • Low-voltage, high-speed power supply designs (e.g., 5V, 3.3V, 2.5V, 1.8V) for embedded systems.
  • Medium-voltage power supply designs (e.g., 12V, 24V, 48V) for systems or standalone products.
  • Live power monitoring integrated into each product.
  • Protection against over-voltage, under-voltage, reverse-voltage, and over-current for all inputs.
  • Lithium-Ion, Lithium-Polymer, and Lead-Acid battery system design, including protection circuitry for safe charging and discharging.
• Analogue Circuitry
  • Custom sensor integration (temperature, light, pressure, etc.) and signal processing.
  • Amplifier design for scaling, accuracy, and improved resolution.
  • Filter design for noise reduction, anti-aliasing, and enhanced system performance.
  • System design simulations to ensure functional prototypes from the first revision.
• Digital Circuitry
  • Intra-board communication protocols: I2C, SPI, I2S, USART.
  • Inter-board communication protocols: RS-232, RS-485/MODBUS, USB, Ethernet.
  • Utilizing integrated sensors and devices.
  • OLED/LCD/Display integration for user feedback and interaction.
• Embedded Systems
  • Time-critical peripheral utilization (timers, PWM, input-capture, sampling).
  • Efficient memory implementation (DMA vs traditional polling methods).
  • Analog-Digital crossover integration (ADCs and DACs, internal and external).
  • External programming for field-upgradable units.
  • Safety integrity using watchdog timers and external EEPROM for reliable self-checking.
• Internet of Things (IoT)
  • Bluetooth solutions for simple master-to-slave IoT control and sensing devices.
  • Wi-Fi solutions for large sensor arrays and networking IoT systems.
  • Cellular design for remote IoT devices requiring global connectivity.
  • GPS/GNSS solutions for precise positioning data.
  • Antenna design and integration for optimized gain in specific applications.
• Schematic Capture
  • High-quality schematic capturing using Altium Designer 19 and circuit simulation tools.
  • Clear system element breakdown into “hardware blocks” for easy readability.
  • Design notes, variants, and layout for easy understanding by non-technical stakeholders.
  • Integrated part numbering and ordering information for streamlined BOM generation.
• PCB Layout
  • Comprehensive PCB design services using Altium Designer 19 and performance simulation tools.
  • Multilayer PCB designs ranging from 1-layer (cost-effective) to 14-layer (complex products).
  • Surface-mount design for manufacturability and production efficiency.
  • Rigid, flexible, and rigid-flex PCB design for versatile enclosure integration.
  • Microwave design expertise, including impedance control for high-speed signal integrity.
  • VHDI experience, including blind/buried vias and via-in-pad for space-constrained designs.
  • Consistent use of 3D models in layouts to prevent mechanical interference.
  • Experience in high-voltage and high-current design, ensuring compliance and performance.
  • Design-for-EMC, focusing on first-time compliance to ease production transitions.
• Assembly
  • In-house stencil applicator and reflow oven for efficient prototype assembly, reducing costs and overhead.
  • No miscommunication errors between designer and assembler, as both are handled by the same team.
  • IPC certification achieved in 2019 to ensure top-quality product standards.
  • Board cleaning for enhanced reliability during performance testing.
  • Faster prototyping turnaround due to in-house assembly capabilities.
