as few profiles as possible is desirable ; however indeed the sizing, mass
and shadowing on hot jets for example represents quite a challenge ;
remember when we first time introduced big electrolyte cans with small legs;
it took another 7'C to reflow them in shade (had actually to shift few
around for better jet flow).
in the end we've had to go much higher much faster before the things popped
.
That contravened max rise speed on other cer caps to make it interesting

Subject: [TN] Oven Profile Recommendations?


I've inherited a system of maintaining oven profiles where each assembly was
given it's own profile.  While this may have been more appropriate with IR,
I don't think that current convection ovens require this many.  I'm
intending to try and reduce our profiles to 6 or so that can cover the range
of products we run.   Is this a practical approach?  I believe it is, but
would appreciate any comments.  I'd also like to get feedback on systems
that are currently being used.  How are you categorizing your profiles
(mass, board size, etc.)?

Thanks.
