I have a customer specification requirement to inspect solder coating 
thickness per IPC-D-949 Class 2.  I reviewed the Design Guide and did not 
find any solder coat thickness requirements.

Where in this IPC spec is the solder coat thickness requirements?

What is the relationship of IPC-D-949 and IPC-D-275?

If I use the solder coat thickness in IPC-D-275, do I meet the 
requirements of IPC-D-949?

Your help is appreciated.
