Dear SIR,
could you kindly provide the update info regarding the maximum bias for the
conformal coating SIR test? Is it still 333 V/mm? assume I use read out at
100 Vdc and bias at 50 Vdc for the B-25A, am I right that bias max is
333V/mm and read out is at 666V/mm spacing? Thank you very much.
Best regards,
jk
ps. I know Concoat recommend low voltage bias, but the current test method
650-2.6.3.4 is still high voltage. (50Vdc bias)... by the way, anyone has
table regarding the dielectric withstanding voltage per IPC-CC-830? Many
thanks.)
