humid environment combined with residue left on the board from vendor
process.  Send a board from the vendor out for contamination testing...you

Subject: [TN] Dendritic growth on top of capacitors


Hi All,

Anyone experience dentritic growth observations on top of capacitors (on a
particular location of the assembly)? I am being told that we are observing
white material growth on capacitors within 2 weeks in an environmental
chamber during testing.

What are potential causes?

Any help is appreciated.

Regards,

Kamalesh
