I need a compact, production-ready PCB designed for a new consumer-grade smart-home device. The board’s core task is to handle a dedicated control-interface switch that will let users toggle the appliance on and off and cycle through a few operating modes. Space is not tight, so component selection and trace routing will be no problem. You’re free to work in Altium Designer, KiCad, or Eagle—whichever lets you move fastest while still delivering neat, well-documented files. If you choose RF-friendly parts, please keep the layout compatible PCB Easy or JLCPCB. Deliverables I expect: • Schematic and PCB layout files • Gerber, drill, and pick-and-place outputs ready for fabrication • A tidy BOM with supplier part numbers and current pricing &bull...
I need a double-layer, signal-processing board laid out in Altium Designer and prepared for fabrication at JLCPCB. The finished board will fit inside a 15 cm × 15 cm envelope, so component placement, routing, and keep-outs should respect that medium-size constraint. Deliverables I expect: • Complete Altium project with schematics and PCB layout • Optimised Gerber, drill, and pick-and-place files matched to JLCPCB’s specs • BOM with manufacturer part numbers and assembly notes I will review the design by importing the files directly into Altium and running JLCPCB’s online DFM check; the job is complete once the files upload without errors and the board passes ERC/DRC.
I have three existing Altium Designer projects that must be refreshed before the next manufacturing run at JLCPCB. Both the schematic and the board layout need attention. On the schematic side I already know the exact edits: a handful of parts have to be added or removed, several nets must be reassigned, and a few voltage- and current-related values updated. Once those changes are in place the PCB layouts have to be brought in line—rerouting where required, keeping the original board outlines and mechanical constraints intact, and making sure every DRC/ERC check comes up clean. When the files are solid I need a full, ready-for-upload manufacturing package: • Updated Altium project files (.PrjPcb, .SchDoc, .PcbDoc) • Gerber and NC-Drill set generated with J...

The PCB must be designed using Altium Designer and be ready for manufacturing. Deliverables should include schematics, PCB layout, Gerber files, BOM, Pick & Place files, and basic manufacturing documentation. Components should preferably be selected from Özdisan Electronics () to ensure reliable supply for production. We are looking for engineers with real experience in industrial PCB...
