For a connector that stays mated for the life of the product, this plating grade is fine; for a service port or reworkable interconnect, you'd want thicker gold. ## Solder Retention for Reflow Stability On a 40-position part at 0.40mm pitch, those retention points matter: the fine-pitch leads alone don't provide much mechanical grip during soldering, and a tombstoned or shifted connector is a board-level failure.","metaTitle":"Molex SlimStack 5017450401, 0.40mm Pitch, 40 Pos Plug","metaDescription":"Molex 5017450401 SlimStack plug, 40 positions, 0.40mm pitch, 2 rows, gold contacts, 8.00µin plating.
