I know this sounds silly.  Replace 805 pkg resistors with 605 pkg
resistors.  Believe me it is a wiser option than fiddling with pull
test, vibration test, reliability test....so on.
Anyway, Who is your end-customer, GM, Chrsyler, Ford, Nissan
or Toyota?  Hey, making sure my next car won't crash  on me
with repair bills...

Dear experts,
We are building electronics for automotive industry.
We have a number of boards where 0805 package resistors
were placed and
reflowed on the 0603 pads.  As the results there is no side
concave solder
fillet, only under the component terminations.

What options other than scrapping the boards would you
suggest? ( Rework:
remove and replace. Do some testing (vibration, pull test??).
Please, help
Thank you, very much
Stella N
