Therein lies the issue. Unknown storage conditions before we received the PCBs, date codes just expired (2 weeks), first article is de-lam city! Had a bad feeling about it. Have read some studies showing that there is no linear tie in of visual cha

I am actually a final year student in Brunel University,London. I`m just started with my major project and the main objective of this project is to perform feasibility study on automation in dust removal. My project title is Automatic PCB Surface Cle

Tim, 1. You dont need the vacuum verify if the quadalign is working properly. If you have the part quad-aligned and dont have alignment type at 0 it will never 'not' place a part. More or less...the vac verify was needed for the chucking machine (3c)

I have a problem setting up the LAE on my Quad 4c. I set it up for 0805, and it seems to work, although it rejects a lot of parts, at least it places "most" of them. I tried setting up on a soic14, and could not get even one to pass. I believe I h

When I see this on my QSP2 it is always caused by the nozzle not seating ideally but I tend to set my tolerances really tight. To test mount a nozzle and look at Z height. Now pick up the part (which in my case will suck the nozzle upward due to the

More lube on the O-Rings caused lots of problems. Nozzles would drop downward at times. So I pulled everything out and started from scratch. Testing 3 new Z-Rods, 4 used Z-Rods in good shape (replaced the O-Rings) and around 20 nozzles - the proces

I've been busy with a bunch of different projects lately, so I hadn't had a chance to tackle this further until recently. I ended up running through all your suggestions another time and low behold, it seems to have solved the issue. I'm currently no

Does anyone know how to make the vision alignment work on a Quad 4C? What I mean is make it work right, and reliably. I know how to define the component for inspection (lead pitch, lead count, dimensions, tolerances, etc.), and I know how to set ligh

Brian, thank you for taking time to discuss your buying experience, I read your link and it was very thorough. I also work for a small CEM using Mydata equipment. We have had Mydata going back to 1998 but truely are looking for something simpler. F
