Apparently it is a secret (or they don't know). Looking at the Enthone web site they have documents that list all their physical and process parameters, but nary a word on electrical characteristics other than dielectric breakdown voltage and resistivity. Unless someone has acquired this info already be some means, I'd suggest contacting an apps engineer at Enthone and asking. -Ray > > >Hi: > > Does anyone, offhand, happen to know the dielectric constant and loss >tangent for DSR-3241 soldermask? > >Thanks, > >Matt > ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
