Class 1 — General Electronic Products - 🧠ANSWER ✔✔Includes products
suitable for applications where the major requirement is function of the completed
assembly.
Class 2 — Dedicated Service Electronic Products - 🧠ANSWER ✔✔Includes
products where continued performance and extended life is required, and for which
uninterrupted service is desired but not critical. Typically the end-use environment
would not cause failures.
Class 3 — High Performance Electronic Products - 🧠ANSWER ✔✔Includes
products where continued high performance or performance-on-demand is critical,
equipment downtime cannot be tolerated, end-use environment may be
uncommonly harsh, and the equipment must function when required, such as life
support or other critical systems.
, Target Condition - 🧠ANSWER ✔✔A condition that is close to perfect/preferred,
however, it is a desirable condition and not always achievable and may not be
necessary to ensure reliability of the assembly in its service environment.
Acceptable Condition - 🧠ANSWER ✔✔This characteristic indicates a condition
that, while not necessarily perfect, will maintain the integrity and reliability of the
assembly in its service environment.
Defect Condition - 🧠ANSWER ✔✔A defect is a condition that may be insufficient
to ensure the form, fit or function of the assembly in its end use environment.
Process Indicator Condition - 🧠ANSWER ✔✔A process indicator is a condition
(not a defect) which identifies a characteristic that does not affect the form, fit or
function of a product.
Conditions Not Specified - 🧠ANSWER ✔✔Conditions that are not specified as
defective or as a process indicator maybe considered acceptable unless it can be
established that the condition affects user defined form, fit, function.
Primary Side - 🧠ANSWER ✔✔That side of a packaging and interconnecting
structure (PCB) that is so defined on the master drawing.
