Hi all,

 

I have a processing question.  We are building a CCA with a Xilinx 256
ball BGA.

The problem is there will be some components added after the BGA is
placed. 

Normally we used water soluble flux in hand add.

Is it okay to wash the CCA's with the BGA already placed?

 

I found some information in the archives (one email string recommending
sealing the BGA to prevent water from getting under the lid).

Any other issues with a DI water wash?

 

Thanks,

 

John
