Assuming you mean the 0603 parts, because I didn’t touch the 0402 components and the 0603 look “bubbly”. They’re supposed to look a little more concave, right? I was thinking it was because I put too much solder on. Does that mean the joints aren’t good? Because I tested the circuit and got good connections along the whole column of components.It looks pretty good to me. Note the solder "bubbles" on many of the 0402 parts... that's because they're using the standard SMT pad footprint which is designed for reflow soldering in an oven. Most of the SMT pads on Eggtimer's boards have an extra .025" or so added to the end of the standard SMT pads, to allow the solder to flow out past the leads on the component. It's easier for hand soldering than the standard pad footprint.
