Hi again Bob, I checked the theta motor coupling and the set screws are definately tight. I noticed that the theta motor drives an snti-backlash gear (nice design) so there is no play there. It appears that the gear drives a slotted shaft which is d

That's what we do with our MSHII's...setup one carriage offline while the other one runs. We also have setup carts to load the feeders ahead of time and haul them out to the lines. Of course, when we exceed the carriage capacity of 75 slots for an

Looking at low cost reliable Mother-Daughter board interfaces. Looking at having the Mom w/ a routed out slot, like 1.7mm wide with solder lands on the bottom side then plugging in Daughter thru Mom's slot w/ the Daughter having board edge contacts t

chips up to 1411 ( I have not seen a 1411 component yet, but 1210 is a good number ) in 8 mm, IC up to SO8 in 12 mm, IC up to SOL 20 fit in 16mm tape. This is just a basic rule. You may also find SO 20 in 24 mm tape. More important is the reel width,

Elongated slots!! Our older runs are a pain sometimes with parts (1206, 0805 chips) twisting as they go through cure. I'm sure that its not all due to the dots, but I'm sure that it doesn't help either. We don't see this effect on our runs that us

Hi, Our Fuji CP65 nozzles are jamming in the up position. Mostly on caps and resistors, the .7mm (0402) and 1.0mm (0805) and 1.3mm (1206) sizes. They seem to be catching internally where the little peg slides down the slot. If you twist them they

FSW, Another suggestions is if you have rail on your product and you are concerned about stress fracturing certain components you could add a routed slot to add relief in that area. So when you snap the rail off their would be no stress in that area

I haven't worked on that machine in a while but here's a couple things to check. I'm pretty sure the verifier "feeders" have to be in the first feederslot on each side, make sure they are there. I think offsets for the verifier "feeder" are automat

We have a couple of Zeva/Juki PM570L's. One machine has developed a fault with the z axis motor. It is continually 'buzzing', we have checked and there is 24VAC on it. Although even on the other machine there is AC voltage on the motor. We have sw
