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

Hi, First: 1. What os/system? 2. what s/w version? 3. what type of machine model? 4. What type of head configuration? 5. Do you have this head front or back? 6. Do you have encounter this problem before? 7. Have you recently placed any new "high com

OK, here we are: 1. OS is OS&2 2. Sw. is USOS V1.14 3. GSM1 4. 2 Flex2 heads 5. Problem is on the front head 6. No 7. No 8. It just stops in the middle of the placement phase, with the head over PCB area. Usually 2 parts are still held on the nozz

Specs for Bow and Twist for PCBs (IPC-A-610C, 10.6. There may be an update by now). I also have a note in our quality guide referencing (IPC-TM-650, 2.4.22) and (MIL-STD-105D). In summary, a PCB should not bow more than 0.040" with all four corner

It really depends on the assemblies/components that need to be inspected and the available budget. 3D machines are much more reliable at detecting faults while not generating masses of false calls but of course they cost more than 2D machines. I ha

Yes, your observation is accurate. Different process steps have different inspection requirements which necessitates employing different imaging technology to ensure the best performance (detection and throughput). Orbotech, for example, offers both

We started looking at tabletop AOI systems last year, one of the main criteria, as we are a SC was that the sales engineer programmed one of our boards in front of us so we could see just how easy to program it was, also high on the list was performa

It sounds like 3D imaging is much better at fault detection for partially visible leads like SOJ packages. Can any of the 2D systems actually do a solderjoint inspection on the outer rows of BGAs or is the angle too acute to accurately look at these.
