I am looking for a industry specification for the amount of strain that is allowable during a parallel blade shearing operation as related to ceramic capacitors. Does anyone know of such a specification? Best regards, Jeff

Sorry, I was not clear. I am interested in the strain on the PCB during depanelization using a parallel blade shear. And the effect on ceramic capacitors on the PCB. I was not shearing the capacitor off of the PCB. Regards, Jeff

Oh, OK. There is not specification for that either. Capacitor fabricators [eg, TDK, Kemet, AVX, etc] give good guidelines. For instance: http://www.kemet.com/kemet/web/homepage/kechome.nsf/vapubfiles/F2111/$file/F2111.pdf

Has anyone experienced problems lately with excess flux residue left on the board after reflow when using Alpha UP78 OSP paste? We are getting a component failure that the designers are blaming on too much residue. Thanks

Nope, haven't heard anything. I'd check your reflow profile, contact Alpha. Also, UP78 is a very old solderpaste product. I would consider switching to one of their newer products.

When you say "very old" do you mean it's discontinued? My supplier is telling me they still sell it. In this case, the residue is pooling up and clogging up a switch. That's what we are considering too much. Thanks.

Yes, old not obsolete. I believe it may be Alpha's first no-clean solderpaste model. Their most current NC model is OM 5000.
