CSD23382F4: Termination finish plating process

Part Number: CSD23382F4

Tool/software:

From a previous post on the NiAu termination finish..."the CSD23382F4 termination finish is 1um Ni and 0.08um Au" Can you tell me what type of plating process is used on this part? I have a very old correspondence from TI Customer Service that states the termination finish on the CSD23382F4 is "electroless-nickel-immersion-gold (ENIG)", but I question that because the ENIG plating process is typically used on printed circuit boards, whereas electroplating is more commonly used on component terminations. The reason for my question is related to gold removal requirements in J-STD-001H, which shows an exemption for "ENIG" plated finishes. 

  • Hello David,

    Thanks for your interest in TI FETs. As you have stated, the CSD23382F4 termination is 1um Ni and 0.08um Au. The termination process is electroless nickel immersion gold (ENIG). The gold flash is to prevent oxidation of the Ni, enhance solderability and dissolves into the solder during reflow. Please let me know if you have any additional questions.

    Best Regards,
