Hi all,

I have been noticing on our last batch of boards that we ran, some of the
tsop flash chips were not reflowing properly.  I am not getting very good
toe fillets on the chips and some appear as though they are just sitting on
top of the reflowed solder.  This board has a good component mix(i.e. BGA,
QFPs, PLCCsocket, SOICs, total(325-350)).  Other components reflow fine,
but for some reason these TSOPS are not.  Is there something that we are
overlooking?

Your input would be greatly appreciated.  Thanks in advance

Tom
