Hi,
I want to check feasibility of using laminate substrates for an application
that needs high voltage isolation (several kV) between certain traces.
I am looking at breakdown voltage strength for different materials.
Is the formula sufficient to determine usability?
Breakdown voltage = Dielectric strength x laminate thickness
Or are there any potential concerns with using laminate materials at HV.
I came across some references that mentioned micro-voids in laminate material
can result in lower effective breakdown strength. How can I quantify the
reduced effective strength?
Regards,
Vijaya
