I want to use a two layers FPC to design a slide with CY8CMBR3106S.But I'm not sure  if the soldermask(usually use PI material)  will  affect the sensitivity or not?Should I expose the slide segment pad?

Hi @daxueseng 

 

You do not have to provide a soldermask there. The insulating material will not drastically affect the sensitivity and will help in preventing the copper from oxidising and reducing performance over time.
