Xray Analysis of non-BGA solder joints

Hello New to forum, I have a mpm ultra print 1500 can not find a lube coupler for the Z axis slide bearings. Does anyone know what it is and where could I find one. A standard grease coupling does not fit. Thanks Dale

Testing effect of non-clean flux residue on solder joints

No clean is giving us problem in ICT. Other than that, a coating of flux should remain there to pretect the solder joint from the environment. In general you should not clean NO clean - it is supposed to be there.

For low volume hand assembly, deionized water or IPA should work fine.

RoHS and Non-RoHS products in same ICT Fixture

Just 2 cents, lead free flux residue is no clean?, how about leaded flux? how much flux residue it leaves on both types? is there a clean up procedure after wave solder? or is there a wave solder process?

I have never heard of anything like that. If their was something like that it would be in the tens of thoudands of dollors. I would look at the souce of the contamination and use the money to fix that.

Hi Nicky, Some of our Magazine racks can be dissasembled and break down flat. In theory they would then fit in a screen cleaner. Rob.
