Hi Michael, Nowhere did I say that IS 410 is equal to PC370HR; all I said that both of these Pb-free capable materials are now materials sold by Isola, since Isola gobbled up Polyclad. However, int terms of the properties important for Pb-free capability they are not that far apart. IS 410 [Tg=170C, Td=350C, TE=3.5%, STII=225 ] PC 370HR [Tg=170C, Td=340C, TE=2.8%, STII=227 ] Werner -----Original Message----- From: Jeremias, Michael <[log in to unmask]> To: [log in to unmask] Sent: Tue, Jul 6, 2010 6:14 am Subject: [TN] AW: [TN] MIL-S-13949/EPS0606/IPC-1710 etc Hello Partners, hi Werner Pay attention! IS 410 is not equal PC 370 HR. IS 410 is not filled while PC 370 HR is a filled material with quite different properties mainly in withstanding lead free soldering temperatures, if You use it with thick multilayers and through hole vias.

There is no such thing as IPC-SM-750. IS410 is an Isola lead-free capable base material as is 370 HR [originally from Polyclad] Tg and Td are material properties important for being lead-free capable/ IPC 4101 is an IPC document in its C revision, /129, /24 and /26 are base material categories. IPC-A-600 is an assembly spec. If your drawing has nothing but it on it, your PCB is inadequately specified. In order to understand all of this and how it hangs together, you may want to get my White Paper [see my website]. Regards, Werner Engelmaier Engelmaier Associates, L.C.

Our PCB fab vendor's cert of compliance states that out boards are built per: SM-750/IS410/370HR Tg180 C Td 350 (IPC 4101/129, IPC 4101/24.26, IPC 4552 for immersion gold. The only IPC reference/spec on our drawings is A-600. Please recommend which IPC standards to purchase that refer to/specify standards for class III aerospace type PCBs, and if anyone can fill me in on EPS0606, I'm not getting very far with the web search.
