We are currently using nelco N4000-13-SI and N4000-13 material. It seems a
little 'softer' than FR4 but holds its shape well.
We have not had any populated boards back yet (next week probably) but the
Tg of the material is much higher than FR4 and so I would expect good
performance from the lead free build.
