Electronic Design Jobs

I need a fresh PCB layout for a new consumer-electronics gadget I’m developing. The board has to stay as compact as possible while still accommodating a double-layer stack-up for tighter routing and reliable grounding. I will give you the exact schematic, component library, and mechanical envelope; you translate that into a clean, manufacturable Gerber package plus a BOM ready for assembly. Design for easy pick-and-place, respect my keep-out zones, and keep trace widths and clearances within standard FR-4 limits so the board can be produced by mainstream fabs without extra cost. I’ll review the first pass in Altium (or KiCad if you prefer) and send any tweaks, then we lock the final files and fabrication notes. Deliverables are: • Source project files • Gerb...

The existing PCB is functionally sound, but several components need to be swapped for newer equivalents and a handful of additional SMD parts must be integrated without altering the overall board footprint. The layout will stay largely intact; the job is focused on component-level edits rather than a full redesign. Key work: • Replace specified components with the updated parts listed in my BOM draft. • Add two new SMD devices (a low-profile DC-DC converter and a temperature sensor) into the current schematic and layout, observing clearance and impedance rules already in place. • Update the BOM, pick-and-place, and assembly drawings so everything aligns with these changes. Deliverables: • Revised schematic and PCB layout files (Altium Designer preferred, KiCad a...
