IPC-A-610 - Chapter 7 Exam Questions
& Answers (Grade A+)
Through-Hole Technology -
correct answer ✅- The placement of any component on the
electronic assembly does not prevent the insertion or removal of
any hardware (tool clearance included) used to mount the
assembly
- Bonding material is sufficient to hold the part but does not
encapsulate and cover component identification
Connection Mounting - Orientation -
correct answer ✅Inspection usually starts with a general overall
view of the electronic assembly, then follows each component/wire
to its connection, concentrating on the lead into the connection,
the connection and the tail end of the lead/wire leaving the
connection. The wire/lead protrusion step for all lands should be
saved for last so that the board can be flipped over and all
connections checked together.
*Component Mounting - Orientation - Horizontal
Target - Class 1,2,3 -
correct answer ✅Nonpolarized components are oriented so that
markings are read the same way (left-to-right or top-to-bottom)
Component Mounting - Orientation - Vertical
,IPC-A-610 - Chapter 7 Exam Questions
& Answers (Grade A+)
Acceptable - Class 1,2,3 -
correct answer ✅- Polarized part is mounted with a long ground
lead
- Nonpolarized component markings read from bottom to top
Component Mounting - Lead Forming
Defect - Class 1,2,3 -
correct answer ✅Lead is kinked
Component Mounting - Lead Forming - Space between Seal/Weld
and Bend
Acceptable - Class 1,2,3 -
correct answer ✅Leads of through-hole mounted component
extend at least one diameter or thickness but not less than 0.8 mm
[0.03 in] from the body, solder bead, or lead weld
Component Mounting - Lead Forming - Space between Seal/Weld
and Bend
Defect - Class 1,2,3 -
correct answer ✅Fractured lead weld, solder bead, or component
body lead seal
, IPC-A-610 - Chapter 7 Exam Questions
& Answers (Grade A+)
Component Mounting - Lead Forming - Stress Relief -
correct answer ✅- With camel hump bends. Configuration
incorporating a single camel hump may have the body positioned
off-center.
- Loop bends may be used if the location of the mounting holes
prevents the use of a standard bend if there is no possibility of
shortening the lead to any adjacent component lead or conductor.
Use of loop bends may impact circuit impedance, etc., and shall be
approved by design engineering
Component Mounting - Lead Forming - Stress Relief
Acceptable - Class 1,2,3 -
correct answer ✅- Component lead exiting component body is
approximately parallel to major body axis
- Component centering may be offset as a result of the type of
stress relief bond
Component Mounting - Lead Forming - Stress Relief
Acceptable - Class 1
Process Indicator - Class 2
