A good solder connection should have no pits or holes, indicating a smooth and even surface. Additionally, it should have a good concave fillet, meaning the solder forms a smooth curve between the components being joined. This ensures a strong and reliable connection.

The phase angle of an alternating current (AC) sine wave is measured in degrees. The phase angle represents the displacement of the wave from a reference point, typically measured in degrees. It indicates the position of the wave in its cycle and helps determine the relationship between different AC waveforms. Hertz measures the frequency of the wave, seconds and minutes measure time, but degrees are used to measure the phase angle.
