Hi Jack,
Thanks for the kudos.
Let's first be precise with our language: there is RoHS-compliant and RoHS-capable—not the same ting at all.
Also, there is 'dicy'-cured, phenolic-cured as well as non-dicy/non-phenolic-cured; the last is designed to fix some problems with phenolic-cure resins.

 Unfortunately, IPC-4101, even the C revision is not adequate for specification purposes—that is why I developed the White Paper.
I fully agree with Dewey's testing recommendation.
Werner

Well, we avoided it as long as we could, but now I have to design for RoHS

compliance.



I'm basically following Werner's recommendations (which don't conflict with

anyone else's as far as I know), but I'm confused about one aspect of

material:

Several sources have stated that its better to use "NON-DICEY" material, but

none of the IPC-4101 slash sheets mention dicy or non-dicy (or

dicyandiamide).

If we are trying /126 material, do we still have to specify non-dicy?



thanks,

Jack
