Dear André,

Because previously I was using THB120N which had obsoleted, and SU8 was
suggested as replacement. I already have photo masks for negative resist,
therefore I continue to do evaluation for SU8.
I post exposé bake at 95C for 120S, while my plating temp is at ~45C for 24min.
I thought this plating temp is not high enough to harden the SU8?

Thank you.

Best Regards,
Jocelyn
