Dear. Miyasaka san
answered for you questions me.
* Vibration M/C condition was for MP condition or Not ?
Yes,condition confirm testing of M/P.
* Where was defect point of Sn-plating after 16th cycle ?
It's not the same point in plate but the defect character Same as the previous.
* 15th cycle of vibration is enough for MP ?
It's is enough, but for the best of product if you up Sn-thickness to target 8 um.15th cycle It would be more.
If you have any questions or recommendation, please let me know.
Thank you very much for your support & Best regards,
