DFM (Entwurf für die Fertigung) Jobs

I’m working with a physical, consumer-facing product that has already reached a functional prototype. At this stage I need a product designer who can take the rough build and turn it into a design that is attractive, user-friendly, and ready for mass production. Here’s what I’m looking for: • Translate the current prototype into fully detailed 3D CAD, paying attention to ergonomics, tolerances, and ease of assembly. • Optimise material choices and manufacturing methods so the design can move straight into tooling without costly re-work. • Produce photorealistic renders that highlight key use-cases for investors and marketing. • Supply final production files (STEP or IGES, plus 2D drawings with dimensions and call-outs) along with a concise desi...

We are building a solar-powered, low-power IoT field device used outdoors in orchards. We need an experienced PCB design engineer to develop a custom PCB that integrates and reliably powers the system. Scope (PCB only): 1) Schematic + PCB layout for a low-power embedded system 2) Power design: solar charging + battery management, stable rails, protection, brownout handling, and power-path switching 3) Interfaces for MCU + peripherals (camera, GNSS, cellular modem, temp/humidity sensor, RTC/power scheduler) 4) Connector selection, ESD/weather-related protection considerations, test points, and design for manufacturability Deliverables: production-ready Gerbers, BOM, pick/place, schematic, and design files (KiCad/Altium—your preference) Nice to have: Prior experience with solar/batt...

I’m building a pair of DIY tower speakers and need a custom-designed, two-layer PCB that ties everything together. The board must fit comfortably inside the cabinet, so please keep your layout within 260 mm (W) × 190 mm (H) and use 2 oz copper. All core functions—amplifier stages, passive/active crossover networks, and an onboard Bluetooth module—have already been mapped out in a block diagram that I will share. Your job is to translate that diagram into a production-ready board, routing power and signal paths cleanly and meeting good audio-grade practices for noise, thermal management, and grounding. Once the schematic and layout are complete, I’ll need the standard fabrication package: • Gerber and drill files • Read-me with stack-up and cop...

We need a PCB designed in KiCad 8.x for a compact RS-485 sensor node that measures temperature and humidity. Quality, DFM compliance, and proper protection circuits are important. Board overview: 55 × 30mm, 2-layer FR4, black solder mask, lead-free HASL MCU: ATtiny1614 (SOIC-14) Sensor: SHT41 temperature/humidity (DFN 1.5×1.5mm) Communication: RS-485 half-duplex via MAX3485 transceiver Connectors: 2× RJ45 (daisy-chain in/out) + 1× JST-SH 4-pin (external sensor port) Power: 5V input via RJ45 → AMS1117-3.3 LDO → 3.3V Full protection circuits: reverse polarity (P-MOSFET), PTC fuse, TVS diodes (RS-485 + VCC + UPDI), fail-safe biasing, ferrite bead EMI filter Thermal isolation between sensor and electronics (routed PCB slot + ground pour keepout) 3-bit solder ...

Project Overview We are building a V1 industrial ESP32-S3 pulse controller for self-service car wash and vacuum stations. The device receives paid commands from a backend (MQTTS/HTTPS), and generates deterministic “coin pulses” into existing industrial controllers. This is not a hobby prototype. It is a field-deployed V1 pilot that must remain stable for years in harsh environments. Operating Environment • Outdoor installation (freeze/heat cycles) • Electrical noise: motors, pumps, inductive loads, relays/contactors • Expected ambient: −30°C to +40°C (design margin required) • Inside sealed IP enclosure can rise due to self-heating (design for up to ~+70°C internal with reasonable margin) • Humidity / condensation risk (design ...
