Jerry,

The component was not dipped before placement
In the picture you can see the original component placed on top of the
soldered one. It's not dipped.

Jowan,

Was this part dipped in solder before placing?  It looks like solder has
coated the whole lead right up to the body.

Subject: [TN] QFP short at top of the leads

Has anyone ever seen a QFP where shorts occur after soldering at the top
of the leads?
And the leads look pretty dull after soldering.  Any ideas?
