We recently scrapped our TP9-2U because of an issue similar to this. The X-axis would overshoot the pick and place positions. This particular machine(2U)only has 1 X motor. The UFP's and the MY machines have a small fine positioning motor that is on

I have been trying to get the profile right for this part(OMAP3503DCBC) , but still struggle. I'm using the Herller 1809 MKIII oven. I look at the profile recomended by TI and still issue with the solder ball collaps and wetting. My peak temp @256

Welcome to RoHS. Or, at least, to the version of RoHS that I've had to deal with since I started with my current company. Blowholes and pinholes seem to be common in PB-free manufacturing. At least, they have for me here. I also note that IPC has

My company is considering the purchase of Mydata My-9 or My-12 machines vs. Juki 2020 machines. Realizing these two machines have distinct differences in both feeder designs, operational issues, and such, I am interested in others who have analized

I would have said it sounded like a motor/encoder problem...but, since you found the broken resistor, that was likely the source of your issue. The resistor and capacitor are a filter for the motor, MyData likes to put them on nearly all of the moto

We have had this problem before, and Phil was pretty close. On the hydra where the vacuum tubes are connected to the tools shafts you should see a red light inside there. this light locates a lazer cut mark on each of the tool shafts, this lets t

Kathy- Greater than 88%. Is that 3-D Nicolet? I had a conversation with Arline yesterday, she told me about your trials and tribulations with re-balling. I would like to suggest you try micro-stencil instead. If your BGA rework center has the capabi
