Hi Ted,
Here are the pertinent fact about the materials:
Isola IS410 Tg=170, Td=350, TE(50->260)=3.5%, STII=225
Nelco N4000-11 Tg=170, Td=345, TE(50->260)=3.2%, STII=225
Nelco N4000-12 Tg=180, Td=370, TE(50->260)=3.6%, STII=239
N4000-29 Tg=175, Td=350, TE(50->260)=3.0%, STII=232
Generally, the higher the STII the better the material is for LF-soldering
temperatures.
