A customer contract conflicts with IPC-A-610 requirements regarding solder fillet
height. Which document takes precedence?
a. IPC-A-610
b. Inspector judgment
c. Procurement documentation
d. Training manual
Correct Answer: c. Procurement documentation
Explanation: The order of precedence clearly states that procurement
documentation agreed upon between customer and supplier overrides IPC-A-610.
This ensures that customer-specific requirements are always prioritized.
A PCB shows a condition that does not affect performance but indicates slight
variation in the manufacturing process. How should it be classified?
a. Defect
b. Process Indicator
c. Acceptable
d. Not specified
Correct Answer: b. Process Indicator
Explanation: A process indicator does not impact functionality but signals a
variation in the process that should be monitored. These are not defects and do
not require disposition but are useful for process control improvements.

A technician finds a violation in electrical clearance between two conductors.
What is the classification?
a. Acceptable for Class 1
b. Process Indicator
c. Target Condition
d. Defect
Correct Answer: d. Defect
Explanation: Any violation of minimum electrical clearance is a defect across all
classes. This is a critical safety and functionality issue that can lead to short circuits
or failures regardless of product classification.
During inspection, a condition is found that is not mentioned in IPC-A-610 but
does not affect functionality. What should be assumed?
a. Defect
b. Acceptable
c. Process Indicator
d. Scrap
Correct Answer: b. Acceptable
Explanation: Conditions not specified in the standard are considered acceptable
unless there is evidence that they affect form, fit, or function. IPC-A-610 allows
flexibility for unspecified conditions.
Who is responsible for determining the product class for inspection?
a. Inspector
b. Manufacturer

, IPC-A-610 exam prep
c. Customer
d. Quality engineer
Correct Answer: c. Customer
Explanation: The customer has the ultimate responsibility for defining the product
class. Inspectors must follow the assigned class and cannot independently change
it during evaluation.
A technician is inspecting a consumer-grade toy circuit board where minor
cosmetic solder imperfections are present but functionality is unaffected. The
product is categorized as general electronics. How should this condition be
evaluated?
a. Defect
b. Acceptable
c. Process Indicator
d. Target Condition
Correct Answer: b. Acceptable
Explanation: Since this is a Class 1 product (general electronics), the primary
requirement is functionality rather than perfection. Minor cosmetic imperfections
that do not affect form, fit, or function are considered acceptable. IPC-A-610
allows flexibility in Class 1 compared to stricter classes, meaning the assembly can
still be used without concern.
During inspection, a life-support device PCB shows a slight solder void that could
potentially affect reliability under stress. What is the correct classification?
a. Acceptable
b. Target Condition
c. Process Indicator
d. Defect

, IPC-A-610 exam prep
Correct Answer: d. Defect
Explanation: Class 3 products require the highest reliability, especially for life-
support systems. Any condition that could compromise performance—even
slightly—is considered a defect. Reliability is critical, and downtime cannot be
tolerated, so stricter acceptance criteria apply.
An inspector notices a gray, grainy solder joint on a PCB. What is the most likely
issue?
a. Proper wetting
b. Cold solder connection
c. Acceptable solder joint
d. Target condition
Correct Answer: b. Cold solder connection
Explanation: A gray, porous, or dull appearance is a hallmark of a cold solder joint.
This results from insufficient heat, contamination, or impurities. Such joints have
poor mechanical and electrical integrity and are considered defects across all
classes.
A wire is wrapped more than 360 degrees and crosses over itself on a terminal.
What is this condition called?
a. Wire Overwrap
b. Wire Overlap
c. Acceptable wrap
d. Target wrap
Correct Answer: b. Wire Overlap
Explanation: Wire overlap occurs when the wire exceeds 360 degrees and crosses
over itself, potentially compromising mechanical stability and electrical integrity.
This differs from overwrap, where contact is maintained without crossing.
