Wellness Pod PCB Defect Debug
Budget: ₹37,500 – ₹75,000 INR
I have a childcare wellness-pod product whose PCB is giving us trouble. The first production run revealed multiple defects, so I now need a fresh set of expert eyes on the schematic before we spin the boards again.
Main objective
My sole goal is to fix the defects that slipped through last time and deliver a rock-solid schematic ready for refabrication.
Known issues you will encounter
• Electrical short circuits appearing on two power rails
• Intermittent component failures traced to suspect footprints and values
• Noticeable signal-integrity problems on the high-speed lines
The trouble areas are concentrated around the microcontrollers, several capacitor-resistor networks, and the board’s connectors and sockets, so I expect focused probing there first.
What I need from you
1. A thorough design-rule and ERC review of the current Altium schematic (source files supplied after kickoff).
2. Targeted bench-level tests or simulations to reproduce each failure mode.
3. Clear, annotated corrections in the schematic—with any part swaps, value changes, or trace recommendations fully documented—so the fab house can proceed without second-guessing.
4. A concise test report confirming that shorts are eliminated, components stay within spec, and signal integrity meets IPC guidelines for our data rates.
Acceptance criteria
• No reported shorts when the corrected netlist is run through DRC.
• All affected components pass manufacturer-datasheet operating limits in simulation or bench test.
• Eye diagram or equivalent evidence that the critical high-speed bus meets the target margin.
• Final files: updated schematic, BOM, and a change-log PDF.
If you have deep experience hunting down shorts, component stress failures, and SI hiccups on mixed-signal boards, I’m ready to start immediately.
