TPS2120: solder bridges are happend

Koyo Asaishi

Part Number: TPS2120

Hi team,

My customer have made metal mask for TPS2120 WCSP package.

Although the customer followed following solder paste example, solder bridges were happened (just 2% ICs).

Do you have ideas why it was happened?

Hi Koyo,

I do not think the use/application of this device is causing the solder bridge due to the 2% event rate.

It is likely that these bridges are happening during board population since the device is small.

Hi Shreyas,

Thanks for the advice.

I will confirm whether they use NSMD.

Best regards,
Koyo
