Hi all, I am replacing some capacitors on a Bally solenoid driver board and I was curious as to whether it matters in which direction I solder them in. In other words is there polarity for these capacitors?

Thank you

For those, it does not matter.

If you know the part numbers, ceramic are non-polarized and can be put in either way. Electrolitic and tantalum have polarity

And the "greenies" shown in the first image are film capacitors -- also non-polarized.
