Bad SMA connector assembly of AD9082-FMCA-EBZ

Hello,

In the AD9082-FMCA-EBZ picture posted on the website, the connector assembly does not look good.

Soldering is inconsistent and looks excessive.

Please see the mounting Instructions for the SMA connector.

Did you have any problems testing with high-frequency signals?

Actually I'm having a similar problem with connector assembly.

My board is even assembled with the connector tilted.

This mismatch causes S21 to fructurate and attenuate the signal significantly at high frequencies in my board.

In my opinion, ADI needs to check the AD9082-FMCA-EBZ manufacturing process.

I'm thinking about exchanging it, but I'm worried that the new product will be the same.

Best Regards,

Hyeunpil
