Capacitance and Resistance Tests
To guarantee the high-quality of finished printed circuit boards produced by us, EPCB will test capacitance and resistance of PCBs before shipping them for you to use. Capacitance testing for bare circuit boards involves charging a net or plane before probing each net to measure the induced capacity. Inaccuracies do occur with this method due to inherent variability in producing PCBs. Resistance testing measures the resistance found in the net, which is proportional to length and inversely proportional to the cross-sectional area of a conductor. A good conductor will have a low resistance. Only all PCBs pass the capacitance and resistance test can we deliver goods to you.
