The failure doesn't necessarily have to happen at the junctions for the junctions to be a cause. It also makes sense that the edge pins would heat up more because they're both surrounded by less mass and a likelier conduit to distribute current and heat based on the resistivity of the shown wiring.
Reminds me of the molded MOLEX to SATA adapters for HDDs that suffer from similarly shoddy wiring design and are prone to melting/fires. https://www.youtube.com/watch?v=fAyy_WOSdVc https://www.youtube.com/watch?v=fAyy_WOSdVc
- deng 4y ago> The failure doesn't necessarily have to happen at the junctions for the junctions to be a cause. Indeed, it can also happen that because some connection is failing, too much current flows through the remaining ones, but this is clearly not what is happening here (because it's not the inner connectors that are melting, and also because Igor tried and couldn't replicate this). This really looks like heat from high resistance, and the outer connectors are simply those experiencing the most mechanical stress, and it's really easy for these 2-slit-connectors to get bend out of shape.
- Latty 4y agoAh yes, the classic "MOLEX to SATA? Lose your data!".
