Authoritative datasheet: Cincon CQB150W Series Datasheet Official product page: Cincon CQB150W
Audit complete. The 8-pin electrical mapping and main quarter-brick geometry match the Cincon datasheet, but footprint drills for power pins 4 and 8 are critically undersized—1.22 mm holes for 1.50 mm pins. Metadata also incorrectly classifies the converter as a Logic/AND IC, and pin types/descriptions need cleanup.
The existing Datasheet URL was preserved because it was already populated; the official Cincon datasheet was used for verification. Full findings are in CQB150W-24S12 Part Audit. An internal part-quality report was filed.
Fix the footprint drill and pad sizes for pins 4 and 8 per the Cincon datasheet.
The datasheet specifies Ø1.50 mm device pins but no recommended land pattern. I’m sizing pins 4 and 8 to Ø1.80 mm finished holes with Ø3.00 mm copper pads, providing 0.30 mm diametral assembly clearance and a 0.60 mm annular ring.
Fixed and verified footprint pins 4 (-V_OUTPUT) and 8 (+V_OUTPUT):
  • Finished drill: Ø1.80 mm
  • Copper pad: Ø3.00 mm
  • Annular ring: 0.60 mm
  • Pad type: plated through-hole, circular
These dimensions accommodate the datasheet’s Ø1.50 mm power pins with practical assembly clearance.
