I guess these are two very trivial questions, but I couldn't find any conclusive answer.
Below is a part of a PCB I want to create (my first ever), a SOT23 transistor and a 0805 resistor. .
- Are the red trace lines really on top of the surface, or are they underneath? Meaning, if my soldering wouldn't be so well and I spill a bit over the red traces, would it matter (since they are on top of the PCB) or are they underneath and doesn't matter at all? In case they are on top, I might need to increase the distance between traces and components.
- Since pin 5 of the SOT23 is connected to pin 1 of the resistor, can I just put a blob of solder between 1 and 5 (when I put them even closer together) ? Since I'm not sure of above, I will either have one or two paths (which both are ok I guess).
(note: my PCB will have only two copper layers, one F.Cu for signals/VCC and one B.Cu layer that is mostly ground).
