Read the first 7 Regulatory Frameworks & Compliance flashcards as text

  1. What is the primary purpose of the REACH regulation in the context of PCB design?

    Answer: Controlling registration and evaluation of chemical substances

    REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) requires manufacturers to identify and manage risks from chemicals used in products including PCBs.

  2. A PCB design engineer adds copper fill to reduce impedance and minimize EMI. Which FCC test limit category applies to a device sold commercially in the US for home use?

    Answer: Class B (residential)

    FCC Part 15 Class B limits apply to devices marketed for residential use and are stricter than Class A industrial limits.

  3. Under IPC Class 3 requirements, what must be done to conformal coating voids discovered during inspection?

    Answer: They are rejectable defects requiring rework

    IPC-A-610 Class 3 treats coating voids over exposed circuitry as rejectable conditions that require rework to ensure reliability.

  4. Which marking must appear on a product sold in the European Economic Area to declare conformity with applicable EU directives?

    Answer: CE mark

    The CE mark (Conformité Européenne) is a mandatory conformity marking indicating a product meets EU health, safety, and environmental requirements.

  5. IPC-2152 provides guidelines for which critical PCB design parameter?

    Answer: Conductor current-carrying capacity

    IPC-2152 is the standard for determining current-carrying capacity of printed board conductors (trace current ratings).

  6. When designing a medical PCB classified as IEC 60601-1 Class IIf, what does the 'f' suffix indicate?

    Answer: Direct cardiac application with highest leakage current restrictions

    The 'CF' (cardiac floating) type in IEC 60601-1 indicates the applied part can make direct cardiac contact, requiring the strictest leakage current limits.

  7. What is the significance of the IPC-7711/7721 standard for PCB compliance?

    Answer: It provides procedures for rework, repair, and modification of PCBs

    IPC-7711/7721 establishes procedures and requirements for reworking, repairing, and modifying electronic assemblies to maintain compliance.
