TopicDatasheet note
AssemblyPad pattern is a general recommendation; high-density applications should optimize it
CleaningWashing agents may damage body, marking, or plating; brushing is not recommended
PottingShrink/expansion can damage device or sealing
Storage timeUse within 12 months of shipment recommended
HandlingPressure on top surface can affect function and reliability
ESDESD prevention methods required during handling
4) Symbol and footprint cross-check Findings

Table

AreaResultRiskDetails
Pin countPassLowSymbol exposes 6 pins and footprint has 6 pads, matching the datasheet
Pin numberingPassLowSymbol terminal numbers 1-6 align with footprint terminal IDs 1-6
Pin polarity mappingPassLowK1, K2, K3 map to cathodes; A1, A2, A3 map to anodes, consistent with the datasheet
Footprint pad sizePassLowFootprint uses 1.0 x 2.8 mm pads, matching the datasheet land-pattern values
Footprint overall pad spanPassLowCopper span is 7.2 mm, matching the datasheet land-pattern value
Package familyPassLowFootprint is clearly built for a 5050 6-pad LED package
Symbol pin namesFlagMediumThe symbol metadata shows pin names as undefined; datasheet functions should be explicit as K1/A1/K2/A2/K3/A3 or C1/A1/C2/A2/C3/A3 in the actual pin properties
Symbol pin electrical typesFlagMediumAll pins are currently Unspecified. For ERC clarity and downstream reuse, these should be set explicitly, typically as passive LED terminals or clearly labeled anode/cathode terminals
Datasheet property namingMinor flagLowProject property is Datasheet URL. If your library workflow expects a canonical Datasheet field, consistency may matter for automation, but functionally the URL is present
Bottom line
  • No footprint-to-datasheet mismatch was found that would obviously cause manufacturing failure.
  • No pin-count or pad-mapping issue was found that would obviously cause incorrect ordering.
  • The main issues are symbol metadata quality, not geometry:
    • pin names are not formally defined
    • pin types are unspecified
Those two should be cleaned up so this part is safer to reuse and less likely to be miswired later.
