Overview:
A client approached us with a challenge: they had several circuit boards in the field exhibiting malfunctions, but it wasn’t clear whether the issues were hardware or software-related. The supplier of our client was reluctant to provide firmware updates, claiming the problem could be hardware-related. To settle the debate and prove the fault was software-based, we implemented a chip-swapping technique that led to a breakthrough.
The Challenge:
The circuit boards were failing intermittently, causing performance issues in the field. The supplier resisted releasing new firmware, arguing the problem might be hardware-related. The client needed definitive proof of a software issue to avoid costly warranty claims and get access to updated firmware.
Our Solution:
We deployed a unique approach:
- Chip Desoldering: We carefully desoldered the chips from the faulty boards and swapped them with identical chips from working boards.
- Testing: By observing how the swapped chips performed on the working boards, we isolated the issue as firmware-related.
- Proof: With this clear, hardware-independent evidence, the supplier could no longer dispute the cause, leading them to release the firmware and preventing further warranty costs.
Outcome:
Thanks to this method, the client received the required firmware update without needing to navigate further disputes with the supplier. This solution saved them from potentially higher warranty-related costs and restored full functionality to their product.
