Using a fine-tip iron and magnifier, he reflowed the joint and added a tiny bead of solder for good measure. The rail still read low. BoardView’s notes suggested checking the related sense resistor network and the sequencing controller. He located the PGOOD pin on the controller IC and probed: it was held low. That meant the regulator was being told to stay off.
: Instantly find specific resistors (like the common failure point ) or ICs on the physical board. Trace Connections
