I have a few questions that I could use some help with:
1) This note exists on a FLEX fab drawing: "During plating of vias all
areas shall be masked with plating resist except those pads indicated
as pads common." Does it refer to selective plating? Can anyone
please explain this and why a design would need this type of process?
2) On this same fab drawing "bend seam lines" are called out on areas
over traces. Can't this break the traces-especially if the selective
type plating is used (doesn't this process make the flex more
brittle)? If bends are required in a flex, what options am I to look
for?
Thank you.
