Other than investing in an expensive tweezer type meter for SMD components, what would be a good method for the layman to find the capacitance of an 0805 ceramic capacitor whose value is below 1nF? My Fluke meter can only measure to 1nF...
You could buy one of those cheap Chinese LCR meters. About $6-10 including shipping and they'll measure down to 30pF or so.
Here's a 47pF 50V 0805 capacitor measured with hand-held jumper leads:
I would check it with my LCR bridge if it was important but you can't beat the price/performance of these things. The design has evolved from a US published front end and hobbyist copy using an AVR and the published equations.
