⭐⭐⭐⭐⭐ This is exactly the kind of layout project where experience saves you revisions, delays, and money. I’m a Professional Engineer with deep hands-on experience delivering first-pass, fab-approved 4-layer consumer electronics boards with mixed-signal, RF, and audio content. Your requirements around DFM/DFT cleanliness, impedance control, RF isolation, and low-noise audio routing are very clear—and achievable with the right discipline. How I’d approach this: Define a clean 4-layer stack-up (signal / solid GND / PWR / signal) with controlled impedance rules locked before routing Partition the board early: MCU core, RF (Wi-Fi/BT), audio, power, and relay sections isolated properly RF routing with continuous reference planes, via fencing, and antenna keep-outs Audio paths routed short, shielded, and isolated from switching and RF noise Early footprint, courtyard, and clearance audit to catch any library or mechanical issues before they become fab problems Final pass focused on manufacturer DFM/DFT rules so the board sails through pre-check Deliverables you listed are fully covered, including native CAD files (Altium/KiCad/Eagle), full manufacturing package, impedance notes, and a clean manufacturer pre-check report. If you’d like, I can also: Coordinate directly with your chosen fab/assembler Tune impedance to their exact stack-up Review schematic risk points before layout starts Happy to get started as soon as you share the files.

@manojachanta7172

Hello. I specialize in production-grade PCB layout for consumer electronics where first-pass manufacturing success is non-negotiable. My focus is not just “clean routing,” but delivering files that fabricators and assemblers accept without questions. I’ve led multiple 4-layer designs of comparable size integrating MCUs, mixed-signal sensors, RF modules (Wi-Fi/BLE), audio paths, displays, relays, and GUI memory. I’m comfortable managing the interaction between noisy digital domains, sensitive analog/audio traces, and RF sections, using disciplined partitioning, reference planes, and impedance-controlled routing. Before routing begins, I proactively audit schematics and footprints against IPC and fab-house constraints, flagging clearance, land-pattern, or assembly risks early—when they’re still cheap to fix. During layout, I work directly from the manufacturer’s capability stack-up to ensure controlled-impedance nets, via structures, and copper balances are correct by design, not by guesswork. You will receive complete native design files, fabrication and assembly outputs ready for turnkey build, documented stack-up and design rules, and a manufacturer pre-check showing the board is production-ready on first submission. If your priority is avoiding re-spins, schedule slips, and uncomfortable emails from the fab, I’m the right partner for this job.
