CID Regulatory Compliance & Legal Framework 2 — Questions and Answers
Question 1: Which IPC standard specifically governs the acceptability of printed circuit board assemblies for Class 3 high-reliability applications?
- IPC-A-600
- IPC-A-610 (Correct answer)
- IPC-7711
- IPC-2221
Correct answer: IPC-A-610
IPC-A-610 defines acceptability criteria for electronic assemblies, including Class 3 requirements for high-reliability products.
Question 2: Under FCC Part 15, a device that unintentionally generates radio frequency energy and is not licensed must comply with emissions limits classified as:
- Intentional radiator rules
- Unintentional radiator rules (Correct answer)
- Incidental radiator rules
- Licensed device rules
Correct answer: Unintentional radiator rules
FCC Part 15 Subpart B covers unintentional radiators, which are devices that generate RF energy as a byproduct of their operation.
Question 3: Which directive requires manufacturers to provide a Technical Construction File (TCF) or Full Quality Assurance route for CE marking of electronic equipment?
- RoHS Directive
- WEEE Directive
- EMC Directive 2014/30/EU (Correct answer)
- LVD Directive 2014/35/EU
Correct answer: EMC Directive 2014/30/EU
The EMC Directive 2014/30/EU requires either a TCF with third-party assessment or a Full QA route to demonstrate conformity before CE marking.
Question 4: What does the concept of 'Design for Compliance' (DfC) primarily aim to achieve during PCB development?
- Minimizing manufacturing cost by reducing layer count
- Integrating regulatory requirements into the design process from the start (Correct answer)
- Selecting the lowest-cost components that meet specs
- Maximizing signal integrity regardless of EMC impact
Correct answer: Integrating regulatory requirements into the design process from the start
Design for Compliance embeds regulatory and standards requirements early in the design phase to avoid costly redesigns after testing.
Question 5: The IPC-2581 standard defines a format used primarily for:
- PCB fabrication drawing annotations
- Generic requirements for PCB design
- Data transfer between CAD/EDA tools and manufacturing (Correct answer)
- Solder mask application specifications
Correct answer: Data transfer between CAD/EDA tools and manufacturing
IPC-2581 specifies a neutral, vendor-independent XML format for transferring complete PCB design data from CAD tools to fabrication and assembly.
Question 6: Under REACH regulation, manufacturers must communicate substance information down the supply chain when a product contains SVHCs above what threshold concentration?
- 0.01% by weight
- 0.1% by weight (Correct answer)
- 1% by weight
- 0.001% by weight
Correct answer: 0.1% by weight
REACH requires communication of SVHC (Substances of Very High Concern) information when concentrations exceed 0.1% by weight of the article.
Question 7: Which organization maintains the Qualified Products List (QPL) that military and aerospace PCB designers commonly reference for approved materials?
- IPC
- ITAR
- DLA (Defense Logistics Agency) (Correct answer)
- UL
Correct answer: DLA (Defense Logistics Agency)
The Defense Logistics Agency maintains QPLs that list pre-qualified materials and products meeting military specifications such as MIL-PRF-31032.
