What are the RoHS activities required in Analog
& Mixed Signal Board design and what kind of results are expected during
board design through RoHS Analysis?
I don't think RoHS Activities are during board design, it comes in Component selection part & also RoHS analysis comes under Component level & assembly level not board design level.
The printed circuit board material selection is part of the board stack up; it is also early enough in the design to pick a fully ROHS compliant, i.e. halogen free, laminate material.
I don't think in early in the design to pick a fully RoHS Compliant, before going to generate a gerber files, mention in FAB Notes, Fabrication people will take care about Halogen free, Laminate material.
I am not sure what you mean by "Fabrication people", but from past experience, it was quite early in the board design level, where the printed circuit board material properties, such as glass transition temperature, decomposition temperature, and board surface finish were defined and listed in the fabrication notes-those notes became a standard for other pcb's as well.
Also, before inclusion in the schematic..a part must have a symbol with defined electrical connections, pin names, etc.., also, from experience, I found that it is good practice to include other attributes such as ROHS status, MSL information within the part symbol.
Remember, a part becomes a component only after the placement/layout take place.
