Hi,

Is there anyone experience in reflow soldering a ceramic WQFN from NEC.

I encountered dewetting solder joint. I wandered if the
solder fillet observed to be bulky and there is no good
evidence of solder contact.

I hope someone can advise me what is needed to handle such kind of component - WQFN.

Thanks.

Poh
