PBEH-453561874321(MPN:5SGSMD5K2F40I2N) FA requirement from Flex(suzhou)

FA-requirement

PBEH-453561874321(MPN:5SGSMD5K2F40I2G) failed on ICT station at Flex  because the resistance value of 3.0V to GND is lower than normal. The defect rate is about 4%(=9/224).

We need manufacturer to do failure analysis for defective component. the FA sample quantity is 3pcs.

could you please arrange the FA as soon as possible?

please tell us the express address and receiver information so that we can send the samples to you.

Hi ,

Can I confirm again the pin name for 5SGSMD5K2F40I2N having low resistance value to GND?
Do we have more granular information aside from the device has low resistance? Do you observe other functional failure information?

We have two kinds of failure as below:

Pins AU31&AW33 to GND low resistance (around low than 500 Ohm), the defective products is 2pcs.

Pins AU28&AW30 to GND low resistance (around low than 1.2kOhm), the defective product is 1pc.

This fail will impact our ICT test of PCBA.

Could we send these defective products to you to do failure analysis?

Please help to arrange the FA requirement.

Hi,

I had replied your questions.

Do you have any other questions?

Would you please arrange the failure analysis?

AU31&AW33 , AU28&AW30 are VCC pin. VCC pins short to ground is one of the symptoms of EOS.
In order to avoid electrical damage, the device should always be handled in a static-free environment and all the input signals should remain within specified limits, as recommended in the PSG Data Book and associated application notes, at all times.

For your information, EOS is fall under mishandling issue.

Hello,

Flex has strict ESD control throughout the manufacturing process, and the personnel operation also meets the ESD requirements, so we don't think the short circuit is caused by EOS. We hope you can arrange the failure analysis and find the root cause.

I need some confidential info to validate further. Hence we will continue this case there.
