Capacitor: Influence of soldering

If a capacitor with a low capacitance value is soldered to a FR4 circuit board, how much is the influence to capacitance value?
The capacitor is a 0402-SMD component with 1pF.

As a first guess, you have to add the PCB pad and trace capacitance.

Regarding to your knowledge that you have procured, this cap. has C0G class and it should have very low temp. coefficient.
The capacitance variation must be very low unless you don't overheat the cap. terminals.
