PROJECT EXAMPLES

What we have worked on.

A selection of customer projects, anonymised. Task, approach and result show how we work. We do not disclose customer names or confidential details.

BUILDING AUTOMATION · RETROFIT

Task: A manufacturer's existing door-mounted and DIN-rail devices had to fit smaller enclosures and become more economical to produce.
Approach: New PCB layout based on the existing schematic, with stacked boards. Component replacement in the power supply, half-wave instead of bridge rectification and keep-out areas for selective soldering. Implemented directly in the customer's ECAD system.
Result: A finished, production-ready layout, followed by three consecutive orders.

TARGET 3001! · Fusion 360 Electronics

POWER ELECTRONICS · SCHEMATIC

Task: Schematic of the control and driver electronics for a push-pull converter with SiC power semiconductors.
Approach: Hierarchical schematic with 13 sheets: analogue PWM generation with PI controller and adjustable dead time, gate drivers, separate logic supplies, temperature sensing, overcurrent and fault shutdown.
Result: A fully documented schematic as the basis for layout and commissioning.

KiCad 9

SENSORS · FROM SCHEMATIC TO BOARD

Task: Compact board for a monitoring device with temperature measurement, digital inputs and cellular connectivity.
Approach: Schematic and layout with a Wi-Fi microcontroller module plus a connected GSM cellular module, two NTC inputs via a 16-bit ADC, optically isolated inputs with surge protection, a switching regulator and screw terminals.
Result: Manufactured and assembled board, integrated into its enclosure.

EasyEDA · Production via PCB service provider

LAYOUT REVIEW

Task: Review of a layout with audio, radio, display and battery supply before production.
Approach: Check of regulator current paths, switch nodes, USB shielding, SD card routing and grounding concept against datasheet recommendations.
Result: Annotated findings with concrete changes, for example a minimal copper area at the boost converter's switch node.
