Which IPC document defines the land pattern (footprint) geometry recommendations for SMT component packages?
Answer: IPC-7351
IPC-7351 (Generic Requirements for Surface Mount Design and Land Pattern Standard) provides land pattern geometries for SMT component packages.
A board must operate in a marine environment. Which standard's salt spray (fog) testing requirements would be most relevant for conformal coating validation?
Answer: ASTM B117
ASTM B117 is the standard practice for operating salt spray (fog) testing apparatus, commonly referenced for corrosion resistance validation of coatings.
Under RoHS 3 (EU 2015/863), what are the maximum allowable concentration limits for restricted substances in homogeneous materials?
Answer: 1000 ppm for lead, 100 ppm for cadmium
RoHS specifies a maximum of 1000 ppm (0.1%) for lead, mercury, hexavalent chromium, PBB, and PBDE, and 100 ppm (0.01%) for cadmium.
For a PCB used in automotive electronics, which standard defines quality management and reliability requirements specific to the automotive supply chain?
Answer: IATF 16949
IATF 16949 is the automotive-sector-specific quality management standard that extends ISO 9001 requirements for the automotive supply chain.
Which IPC standard specifically covers the qualification and performance requirements for high-density interconnect (HDI) PCBs?
Answer: IPC-6016
IPC-6016 provides qualification and performance specifications for high-density interconnect (HDI) layers or boards.
During PCB design review for WEEE compliance, what is the designer's primary responsibility?
Answer: Marking the product with the crossed-out wheeled bin symbol
WEEE (Waste Electrical and Electronic Equipment) requires products to be marked with the crossed-out wheeled bin symbol to indicate separate collection.
What does the IPC-9252 standard cover in the context of PCB testing?
Answer: Electrical testing of unpopulated printed boards
IPC-9252 defines requirements and guidelines for electrical testing of unpopulated (bare) printed boards including continuity and isolation testing.
