Hi All,

We have a 6 layer flex that my customer has to thermal cycle at temperatures beyond the rated Tg's of the material- the end use environment is about as bad as it gets. After repeated thermal cycles we start to see cracks develop in the glue layer used to bond the adhesiveless layers together. Will some kind of via fill help this issue?

Thanks in advance.

Regards Steve Kelly
