I have a Topaz pick&place machine, but the conveyor motor is not working. 1st test - production: Start production in "operation" menu: if I put the PCB the entrace of machine, the assembly head-bank picks up the first 8 components (precede pick is ON) and waits for transfer. After 5-8 seconds the machine throws "PCB Transfer Error" If I switched the PCB transfer mode into manual and adjusted the PCB into the correct mounting position, the machine could be working well, but this mode is very annoying. 2nd test - mechanic: With my hand, I can rotate the gear output of the motor, and conveyor follows the rotation. It needs equal force if machine is switched off or conveyor motor is switched on/off in menu. I didn't hear any sound while motor was switched on. 3rd test - manual switch on: In submenu "conveyor units" I switched on the conveyor motor manually (while covers are closed and machine is not in emergency-stop state. The motor is not working. In menu "output monitor" I switched on the conveyor motor manually, checked the option "slow" and "reverse" mode. The motor is not working. Near the trafo, I've found the control relay of conveyor motor, and I can hear a thick if I switch on/off the motor. 4th test - motor replacement: I have a same type motor(Panasonic M8RX25G4L) and replaced. The motor is not working. Please help me.

So,Anyone can help me for this clip shooting type?

NP 505 HR Sat, 29 Aug 2015 21:45:49 GMT Halogen-free Solder Re-flow Quality Issues http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=18278 I've recently pushed the company I work for to switch to a halogen-free solder that our supplier carries, Kester's NP 505 HR, prior we were using Kester NXG1. NP 505 HR performs great on the screen, we have a lot of down time in between prints (we do small runs, of a variety of different products), and it seems to stay usable longer in comparison. One of the contributing reasons we made the switch was because some of our finer pitch IC's were not printing successfully. The NP 505 HR was appealing because of it's smaller mesh size. However, some of our customers have noticed a difference in appearance in solder joint appearance in contrast to the NXG1. The surface appears more grainy, and dull. The flux looks more viscous as it appears to remain on top of the joint more, adding to the uneven appearance. The flux also appears more transparent, almost milky/cloudy at times, the NXG1 on most of our boards looks almost amber tinted, while still being somewhat transparent. On top of that our inspect team says they can see cooling lines, (which I should say, I have yet to see). Our board substrates are typically .075" FR4, but they can vary down to .031". We also use aluminum, which can be as thick as .125". We are experiencing these results on all substrates. I understand they are different products and they will have different characteristics and appearances. But I was just looking for assurance that they look appropriate, or a point in the right direction from someone who has experienced similar results with halogen-free solders. The spec'd reflow profiles are identical for the two products. I've MOLE'd my ovens with on-board thermal couples and verified that they are functioning properly and within spec. I've tried adjusting my oven temps up, and playing with the conveyor speed to see they were cooling too fast or too slow. Nothing seemed to produce the results we had hoped to see. We've even ran both solders side by side to see if the NXG1 changed in appearance as well, it didn't. Obviously, I know I could include more information, so if there is anything in addition to what I've provided that you would like to know feel free to ask. I was just trying to keep this somewhat short.

I need the ones that have exploded views with part numbers. I have had them in a previous life so I know they exist. If someone has a pdf file they could send, that would be awesome. If you have a hard copy and could send it to me, I could scan it in and return it to you (if you need it back). Can someone out there help me out?

It seems that DEK can’t narrow down what the issue actually is as well. The printer is a DEK Horizon 03i 09 SP13 P02. We are having an issue with the camera. The camera will be operating as it should for every product we run except the top side of a specific product. The camera will check fiducials for a few boards fine but will abort the process. It comes to the fiducial position, the lighting flickers, then the camera returns to home and asks you to remove the board. The only way to clear the error is to reboot the machine. Our error logs come up with 3 separate errors. We have recreated the program from scratch, we have replaced the camera, the firewire cable, and the firewire card. DEK thought it may be static causing it, so we put ESD belts in , ESD stopper on the camera in. I have grounded the boards before they enter the machine. Still the same issue with this one product. Any help would be greatly appreciated, error messages are as follows: File Line Error Context , File Line Error Context , File Line Error Context Fri, 28 Aug 2015 11:59:05 GMT Fuji CP6, CP7 feeder calibration manual http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=18265 Does anyone have a Fuji CP7 or CP6 feeder calibration jig manual that they would like to share?

I am facing with random problem with dropped parts inside reflow oven and I would like to see what is going on inside. Probably some support chain or edge conveyor makes random movements that generate vibration. If You know any equipment and could recommend me that will be great.

Thu, 27 Aug 2015 05:49:53 GMT DeltaScan - Vectorless testing http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=18279 Hey all, New guy here. I'm working with an Acculogic Sprint 4510 flying prober that I have been tasked with figuring out how to utilize DeltaScan features on. I have been able to get one IC to give me positive feedback in regards to reading back signals high enough to break the 300 threshold. I'm having issue understanding how to set up my machine. The help files give little in the way of details and I'm completely new to ICT/Flying Probe testing as it is. My boss took a two week training course 3 years ago, but I have very little experience here. Does anyone know how these tests work, what is needed for this particular machine? I have set up a single stationary bottom probe contacting ground and the heads are supposed to stimulate and measure the delta between pins, but for some odd reason, I can't seem to get other chips to read back any level other than 0, or 1... some might go as high as 14. I hope someone out there can provide me some guidance, I would truly appreciate the help.

They have provided the results and said that it was their fault and will replace. What I want to know is what elements should be present in an immersion silver pad? - Before soldering. Our results show: C @1.42%, Cu @ 3.39%, Ag @ 95.1% Our supplier has said that the "high C element" is the reason for failure. I'm also wondering what high carbon does to a solder joint? Any thoughts would be much appreciated and any information on Imm.S plate results.
