Is anyone using any NanoStar components from TI? It looks like we might be building boards with some soon. We have put down 0201's successfully. But these are a whole other ballgame. They are 0.9mm by 1.4mm with 5 or 6 balls on the bottom. Would thi

How does your machine recognize the part? Does it use vision for ball inspection or a just a body scan? What is the aperture size on the stencil? Have you calculated the area ratio? What is the aperture shape? What type of paste are you using? is

Thanks a lot guys. The part dims are in mm by the way. So last night i was looking at the .pcb file and saw that the pad size and stencil are both .013" while the ball on the BGA is .018" (sorry for switching from metric). Is this ok or can i have en

A 1:1 pad to ball diameter will cause the balls to collapse more giving you less post solder component standoff. Depending on the application of this product and required reliability, you may want to stay with the padstack being used. You may try c

Just have a look at the archives and see what you come up with. There is a hell of a lot more trouble listed there on the Mydata stuff than there is on the Emerald or it's Topaz twin. User-friendlyness? The GUI on the NT-based Emerald (that would be

It's hard to say something is "better" than something else. How is the Essemtec a better machine? Is it faster & more accurate for less money? Is it easier to maintain yourself? Does it have a greater install base and more service personnel per

Just to check and see if I'm using the right formula in my "cost per component placement" calculation is correct or not. Any input would be much appreciated. Total cost of the machine : A Depreciates over 5 years Actual/best UPH obtained 11000 cph

Hi, Have you looked at Siemens F4 & F5? Regarding PMJ from experience I'd steer well clear (i.e. initial cost, flexibility, cost to add functionality at a later date), however a good second user or remanufactured GSM makes a good odd form placer & i
