thanks for all the feedback... we also checked, just in case : - bake the components (no visible improvement) - bake the pcb (50% less tombstone components) - finally we changed LF paste to completely different manufacturer - and booom 0 (zero) tombs

We are having a little trouble with what appears to be a crystalization between our fine pitch parts. The problem appears after a a thourough wash of the pcb when dry. It looks like lead wiskers/haze between the joints.We are using water soluable lea

On the bare boards, no paste, just a bare FAB board. We get them from a PWB manufacturer and inspect them to IPC-A-600 and then ship them to another manufacturer to populate them and we then inspect them to IPC-A-610. I have written several program

Chris, The red/blue filter as you call it (on the MV3L it's called HorzVert Sum I think) has become my go-to light source view for manual visual evaluation of flagged solder defects. Of all the lighting sources available, this one gives me the best

vpblf I actually installed the Uniserver (apache mysql php) WAMP on the AOI machine and there is a setting to make it generate HTML board results, cant remember where off the top of my head. anyhow anyone in the inspection area can now open firefo

Has anyone had any luck programming using the side cameras to inspect for defects on the sides of chip components? We recently had an escape of a damaged chip capacitor that was impossible to see from the top camera but was clearly visible with the

Hello Scott, Simply program the side angle cameras as you would for any other device using the downward camera. For instance, solder joint inspection for a PLCC would utilize a basis window, bridge inspection algorithm and individual solder joint i

Hello Mark, The centroid data you are currently using to program the MV-2HTL may be used with either platform. However, the libraries cannot be shared due differences in camera resolution. The MV-2HTL will have a 1.3 megapixel camera versus the 2 m

We have a Quad QSV-1 pick and place machine that has performed fine for us with the exception of cylindrical glass (MELF) type diodes. The machine often fails to pick these out of the tape to the point where it is easier to hand place them. As far
