Section 5 of IPC-A-610C
Inspection usually starts with a general overall view of the electrnic
assembly, then follows each componet/wire to its connectin, concentrating on
the lead into the connection, the connection and the tail end of the
lead/wire leaving the connection. The wire/eald protrusion step for all
lands should be saved for last so that the board can be flipped over and all
connection checked together. (Obviously addressing a through hole or mixed
technology board.)

The J-STD-001 encourages sampling but does not directly give guidance.
IPC-9191 which superseeded IPC-PC-90 might help with implementation.
