IPC A 610 ACTUAL EXAM PAPER 2026 QUESTIONS WITH
ANSWERS GRADED A+
● Class 1 Product. Answer: General Electronics Product - includes products where the major
requirement is function of the completed assembly.
● Class 2 Product. Answer: Dedicated Service Electronic Product - Continued performance
and extended life required. Uninterrupted service is desired but not required.
● Class 3 Product. Answer: High Performance Electrical Product - Continued high
performance or performance-on-demand is critical. Equipment downtime cannot be tolerated.
Equipment might be used for life-support or other critical systems.
● Who as the ultimate responsibility for identifying the class to which the assembly is
evaluated?. Answer: The Customer.
● Shall. Answer: Invokes a requirement for manufacturers of all classes or product, and
failure to comply with the requirement is a noncompliance to this standard.
● Order of Precedence in event of conflict 1. Answer: 1. Procurement as agreed and
documented between customer and supplier.
● Order of Precedence in event of conflict 2. Answer: Master drawing or master ass. drawing
reflecting the customer's detailed requirements.
● Order of Precedence in event of conflict 3. Answer: IPC-1-610 when invoked by the
customer or contract.
● If documents other than IPC-A-610 are cited, the order of precedence shall be defined in
the _. Answer: Procurement documents
● 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.
● Who dispositions defect conditions?. Answer: The manufacturer, based on 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.
● Cold Solder Connection. Answer: A solder connection that exhibits poor wetting and that is
characterized by a grayish porous appearance.
● What can cause a cold solder connection?. Answer: Excessive impurities in the solder,
inadequate cleaning prior to the soldering, and/or insufficient application of heat during the
soldering process.
● Any violation of minimal electrical clearance is a.... Answer: defect condition for all classes.
