Cory every time I've faced this request it has been in legal line of windows
like this example :
1
antiquated cap fab specified a profile (namely rise, etc.)
2
therefore we've had to comply with such recomentadion in our working profile
(often conflicting every other component)
3
if we did not , we faced a lenghty component validations ; to justify our
deviations
4
Than the product has been only acceptable following only this validated
process .
Everything else is deemed as not complying with ALL of the subconditions .
One out is considered as breaking the chain = reject .

Y
This is usually class 3 process ; which has to be specifically designed to a
validated process .
Still , common enough in class 2 if one does have reasons for the expenses .
X
It has to be admitted ; in the pain of those validations we did discover
that few of our caps are severely damaged by handsoldering (rework) ;
specifically longer than 2 seconds tip contact on some o805 packages ; on
350'C
Z
Agree , not the brightest idea to ask for what you do not want to know :
Optimal is fly within your standard process ; give them a copy of profile
and iron settings upon the completion .
and a FEW boards which has been reworked > separately < (if you do not have
any, make few  : you would not be "trusted").
Sorry to be a cynic ; decades with "informed" counterparts taught me to meet
more or less boxed expectations .
It's way too taxing sometimes to educate set minds .

Go with the feel Cory ; some customers are more equal than others .
Also , this condition you should know prior to quoting .

Let me know if you need to know specifics

Subject: [TN] Rework


Hello Technet

We have a customer that is requesting that no product be shipped that was
"reworked".  I am afraid to ask what their definition of rework is.  We do
rework for defects created in every process in our plant.  The defects and
rework are closely tracked so that the repetitive ones can be designed out.
In manufacturing a product where there are thousands of opportunities for
defects in every assembly, it seems ludicrous to expect to have no rework.

Can anyone offer advice in dealing with such a customer request?

Thanks,

Cory Steeby
