Dear Technetters,

Our part supplier sent a notification document stating that the component we are currently using become an obsolete part and it won't be manufactured anymore.

ENG department have to re-design the product by adding an extra resistor component (size 0603 or 0805) glued somewhere on the PCB. 
This resistor won't be attached/soldered to any of PCB's pads just to be glued on the solder mask with SMT glue.
Two cables will be soldered to this resistor and correspondent devices.

QUESTION(S)??
Would this modification (gluing a resistor on the soder resist) comply with IPC-A-610 class 3 requirements providing appropriate
ECO instruction will be in place showing how to perform product modification?
ENG need to answer a question regarding environmental condition, I suppose it will be ok.
Product functionality is the same.

Thanks in advance for your opinion....
Andy
