IPC A 610 FINAL TEST 2026 QUESTIONS
WITH CORRECT ANSWERS GRADED A+
• 1. 1. Scope.
Answer: Establishes criteria for evaluating the acceptability of electronic
assemblies based on visual inspection, dimensional measurements, and
functional performance requirements.
• primary side typically most complex side; aka "component side" or "solder
destination side".
Answer: defined by master drawing;
• 1. 2. Purpose.
Answer: The document's goal is to help people distinguish between
acceptable and unacceptable electronic assemblies and to ensure that
assemblies are reliable and consistent.
• Class 1 Product.
Answer: General Electronics Product - includes products where the major
requirement is function of the completed assembly.
• secondary side.
Answer: side opposite of primary side
• Class 2 Product.
Answer: Dedicated Service Electronic Product - Continued performance and
extended life required. Uninterrupted service is desired but not required.
• solder source side typically secondary side.
Answer: side on which solder is applied;
• 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.
, • solder destination side typically primary side.
Answer: side toward which solder flows;
• Who ultimately is responsible 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.
• In the event of a conflict, the following Order of Precedence applies: Step 1.
Answer: 1. Procurement as agreed and documented between customer and
supplier.
• In the event of a conflict, the following Order of Precedence applies: Step 2.
Answer: Master drawing reflecting the customer's detailed requirements.
• In the event of a conflict, the following Order of Precedence applies: Step 3.
Answer: IPC-1-610 when invoked by the customer or contract.
• cold solder connection characterized by gray, porous appearance; **Not
Caused by Motion**.
Answer: exhibits poor wetting;
• common conductors.
Answer: conductors that have identical or redundant functions
• If documents other than IPC-A-610 are cited, the order of precedence shall
be defined in the ........
Answer: Procurement documents
• conductor diameter.
Answer: outside wire diameter *not including* insulation
• wire diameter.
Answer: outside diameter of wire *including* insulation
