IPC-610 standards UPDATED ACTUAL Questions And Correct Answers
Terms in this set (18)
What is the purpose of IPC-A-610? IPC-A-610 provides visual acceptance criteria for completed printed-circuit board
assemblies (PCBAs) and other electronic assemblies.
What related standards work in conjunction with IPC-A- J-STD-001 and IPC/WHMA-A-620.
610?
Does IPC-A-610 cover design rules or functional No, it does not cover design rules or functional requirements.
requirements?
What is the focus of IPC-A-610? The document focuses on workmanship.
What does IPC-A-610 provide to help manufacturers? Illustrations and brief descriptions to distinguish between acceptable conditions,
defects, and process indicators.
Class 1 - General Electronics The most lenient class; function is the primary focus, and minor cosmetic defects
are allowed.
Class 2 - Dedicated service electronics Higher Reliability is required. Minor imperfections in solder point may be allowed
when electrical and mechanical integrity is maintained(Industrial controllers,
Consumer electronics).
class 3 - High-Performance electronics The most stringent class; assemblies must meet all IPC‑A‑610 criteria for maximum
reliability and performance. Used for aerospace, medical and military products
where failure can cause serious consequences.
Does a defect at a lower class indicate a defect to the Yes, A defect at a lower class indicates defects to the other higher classes.
other higher classes?
Soldering Quality The standard specifies correct solder‑joint formation, fillet shape and mechanical
strength to avoid defects like dewetting, excessive solder and bridging. Solder
joints should be smooth, concave and fully wetted
Component placement/Orientation Components (through‑hole and surface‑mount) must be oriented according to
assembly documentation, correctly spaced and securely mounted. Leads should
be trimmed and bent properly to ensure good solder joints
Mechanical assembly Thread‑engagement rules and torque specs are defined to ensure fasteners stay
secure. The standard also addresses PCB integrity (e.g., warpage and
delamination limits)
Wiring and cabling Requirements cover wire termination (soldering and crimping), proper strain relief,
correct wire stripping, bundling and routing, acceptable bend radius and
inspection for damage
