Materials declaration form IPC-1752 has a statement noting:
"If the item is an assembly with lower level parts, the declaration
encompasses all lower level material which the manufacturer has
engineering responsibility."

A contract manufacturer supplying a board assembly, by signing this, is
acknowledging only the solder process? Nothing is implied about the
components or board blank?

We can do our due diligence in insuring a compliant Bill of material,
and AVL, but to what extent are those out there off loading that
responsibility to suppliers, and asking them to provide an
all-encompassing declaration?
