Target Condition - ANSWER A condition that is close to perfect, but is not always
achievable and may not be necessary to ensure the reliability of the assembly.
Acceptable Condition - ANSWER A condition that, while not necessarily perfect,
will maintain integrity and reliability of the assembly
Defect Condition - ANSWER The form, fit or function of the assembly is
inadequate for use in its end use environment.
, A defect for Class 1... - ANSWER automatically implies a defect for Class 2 and 3. A
defect for Class 2 implies a defect for Class 3.
Disposition - ANSWER The determination of how defects should be treated.
These include rework, use as is, scrap, and repair.

design, service and customer requirements.
Process Indicator Conditions - ANSWER A condition (not a defect) that does not
affect the form, fit or function of a product.
Process indicators should be... - ANSWER monitored as part of the process
control system
Is disposition of individual process indicators required? - ANSWER No, and
affected products should be used as-is.
Conditions Not Specified - ANSWER A condition that is neither a defect, nor a
process indicator. A condition not specified may be considered acceptable unless
it can be established that the condition affects user-defined form, fit or function.
Primary Side - ANSWER The side of a packaging or interconnecting structure
(PCB) defined as primary on the master drawing. This is usually the side with the
most complex or greatest number of components.
The Primary Side is also known as... - ANSWER the component side, or the solder
destination side (in through-hole mounting technology).
Solder source side - ANSWER The side of the PCB to which solder is applied. This
is usually the secondary side, but might be the primary side in some cases.
Solder Destination Side - ANSWER The side of the PCB that the solder flows
toward in through-hole technology. The destination is is normally the primary
side of the PCB, but might be the secondary side in some cases.
