Dear TechNetters,
We have been specifying, on our Fab Drawings, the use of "Type B"
soldermask. I am under the assumption that this "Type B" is LPI, and "Type
A" is screened soldermask. Is this correct? Where can I find these "types"
defined. As far as I know there's nothing defined in IPC-SM-840C.
Thanks for you help.
Mr. LaVern Mullet
