I have a question. Is solder mask metal?
In this link
for the chip package, it looks like the solder mask is really close(figure solder_mask(.stc).png in the attached file. I am pretty sure the distance between top mental is enough (topmetal(.cmp).png) in the attached file. I am not sure if solder mask means metal or not. If it is metal, it might cause problem when I solder down the chip. I believe the solder mask layer comes from the tstop layer (29) in my design.
Can anyone help on this?
Thank you
