I'm currently dealing with an design of an end effector that need to pick n place a BGA dead bug package. The design is using peumatic system to do the task. Any advise or suggestion on this kind of design?

Base on the PORON foam rubber recommended, is it possible to apply on small BGA chip of 4x4 ball size 0.3mm. Any specific part no and supplier for this type of foam and is it a anti-static material? Would it be possible to punch out at dia. 3mm?

Thankyou very much for the information. Another question, what are the difficulty of dealing with the larger ball and tighter pitch? What is size of the ball is consider large and how far the distance for pitch is consider tight? Currently I have

Larger tighter spaced balls will present a problem in sealing the vacuum cup. There will be more leakage in this case. It really depends upon the application. The BGA you mention should not be a major concern. The bigger problems are with bigger

I think it depends on the thickness of the PORON sheet. For .3mm balls you could probably get away with a pretty thin sheet (maybe 1/16"). I don't know how thin it comes offhand. For the part you are describing I woulf try maybe a 3.5mm OD and a 1

If I understand correctly you want to pick BGAs from the ball side using some type of vacuum arrangement. You will find that the reliability of this is dependant on the size of the balls and the pitch. The larger the balls and tighter the pitch, th

We use CircuitCam extensively, but not for MYDATA. What exactly is the issue you are seeing? Do you have the MYDATA Export module from Aegis?

What about designators? Using gerbers to program a pnp machine was always a last resort to be done only after much complaining and begging for proper CAD data. Back in the day I used UniCAM to program a mydata. After getting it figured out it was eas

I am having trouble programming circuitcam for mydata (my9) pnp machine. My question is, when i digitalize the gerber file what should i take care to get required output for my9? In my9 i cant see exact positions of all the components. I have assign
