Hi Tom!
Send the picture to me, I'll get it posted
as quick as I can.
Just a note to everyone, you don't have to
ask to get a picture posted
on YOUR web page, and that's what it is, a
"Technetter" web page, that's
why I created it.
Kind regards,
-Steve Gregory-

Subject: [TN] Ferrite Core Inductors Fracturing Help
Good Afternoon
I have been a long time reader and learner
and this is my first question to ask.
We are having a problem with our 1002
series
Ferrite core chip inductors, fracturing during our processes.The core
actually fractures causing us failures electrically.
We checked the chip shooter to be sure it
was set correctly for the height of the chip these are High Q component and
run about .008 thicker then our normal non ferrite core inductors, and it
was. We checked with our supplier and they stated it passed there push test
but did not reference any type of spec. Reading there test report it
appears
that the push test is checking to be sure the termination is not separating
from the core.
Our problem is the core is fracturing and
the component is actually breaking.
My question is there a IPC spec that we can
reference that relates to the strength or integrity of the ferrite core,
along with a spec on how much abuse they can take for example at
singulation.
Thx's in advance
I have some pictures that I can post at
Steves site if he gives the approval.
