I recently started an advanced SMD soldering project. I hqve a couple smaller projects under my belt, so I'm raising the bar this time.
I was pre-tinning some 0603 resistor and capacitor pads and must have accidentally scratched the surface of the pcb between 2 neighbor components. The result is that solder flows between the pads of 2 different neighbor components (resistor and capacitor) and now there is continuity between both pads. When I look at the schematic, these 2 components are actually serially connected, but I'm not sure how to confirm that these are the 2 poles that are meant to be connected. So first question is how to go about making this diagnostic?
Second question is how to fix such a mistake? It's amazing sometimes how easy it is to scratch the surface of a pcb without even noticing. I have searched quite a lot online and haven't found a technique specifically for such a problem.
