Fri, 19 Sep 2014 14:53:47 GMT Nitrogen Reflow Oven Does anyone know a rough price estimate on a new nitrogen reflow oven that can achieve very low oxygen levels - around 10PPM. Compared to a similar standard nitrogen oven that would for example go down to 500 PPM, what is a rough price premium for an oven capable of reaching low oxygen levels? Thu, 18 Sep 2014 12:52:08 GMT DEK Horizon 03i I have an issue with this DEK printer our company has been having for over a year now. 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 Thu, 18 Sep 2014 07:26:57 GMT Fuji 643e, turn off advanced part pick up Looking for information on how to stop our Fuji from picking up parts in advance for the next board at the in carrier. In other words, how can we stop the machine from picking up parts before reading fiducials on a board without adding a skip mark to all our programs? Is there a proper setting we can change?

I've got a machine to get running, and, while I have the software manual, something on the hardware would be useful to have. Thanks, ..rob Tue, 16 Sep 2014 19:25:38 GMT FUJI CP65 0201 CAMERA I wonder if anyone can help me with this problem. My FUJI CP65 with 0201 camera is working fine for a while. Now, it starts losing the vision on 0201 camera. The system will run for a while then I don't see the part on the part monitor when the nozzle pickup. At this point, the nozzle check does not work. I think the system can not talk with 0201 camera. Other camera work fine. The system will work again when I do the warm boot by reset the reset switch on the CPU board. I did replace the vision card but it did not help. If you have experience with this problem, please help. Thanks, -Michael Tue, 16 Sep 2014 13:10:34 GMT Reduce PCB pad area on fabricated boards Hi Guys, We are seeing signal integrity issues on PCBs due an improper pad size. We tried to trim down the pad size and it fixed the issue. Problem now is we have many assembled and blank PCBs. Is there a way we can have the pad size reduced on these boards with minimal risk. Plating on the board is ENIG. Thanks! Tue, 16 Sep 2014 13:06:18 GMT How is a Quad calibration slug? Hi evreybody I wish to know if somebody can describe how is made a "Calibration Slug" for centering the upward camera of a QUAD IVC machine. The instruction manual mentions a slug that is attached with vacuum to the "Vision Nozzle" and there is some kind of hole that must to be centered on the monitor's crossshair. I imagine that this piece is a species of polished metal dish or flat pan with a diameter of about 1/2". At the center perhaps there is a small blind hole (maybe 0,5 to 1mm diameter) which acts as a spot to center and focus the camera. How accurate is my imagination? Actually I prefer to hire a mechanician to machine the piece instead of import it. Thanks in advance Best regards Tue, 16 Sep 2014 07:35:18 GMT My9 Optical Beam Splitter Hi guys, New to the forum. I always read and look around at used equipment but have never posted. Anyway, I operate a Mydata My9 at a small shop and have recently ran into a problem and wanted to get some good advice. An employee of mine cleaned the beam splitter glass used on the high res and standard camera, with windex. The windex took off the anti-reflective coating on the glass and ruined it. I called up Edmunds glass and ordered what seems to be the right replacement. When I called Mydata before replacing it they told me they have no idea what kind of glass it is and I need to buy the whole vision system.... Anyways. Does anyone know what kind of glass is used in the optical unit? Any ideas or advice is greatly appreciated. Thank you Mon, 15 Sep 2014 14:14:47 GMT Need help identifiying capacitor Hi folks. I need help identifying a replacement for this component, I believe it's a capacitor. It is marked AVX 9915 on one side, and 15uM and 15V on the other side. Unit in picture is the good one on the board, the one I need to replace has literally exploded. I've googled the AVX 9915 to death with no results. A search of Mouser turned up nothing either. Anyone? Thanks. Mon, 15 Sep 2014 10:28:15 GMT Does anyone knows a European Auction company for SMT equipment? Does anyone knows a European Auction company for SMT equipment? Mon, 15 Sep 2014 04:39:55 GMT best way to get power to PCB Hello Esteemed Panel, I have a question...what is the most cost effective way to get power to a PCB? By this I mean connecting power and ground without a connector but something more reliable than soldering a wire directly to the PCB. Whatever solution you mention please also elaborate somewhat on the process involved (i.e. is it surface mount?...through hole?...can it be automated?)

Thu, 11 Sep 2014 17:28:57 GMT MY12 F-MOT-MSETDYN x/12: Position Counter Dead I am looking for some help for where to look to fix this MY12 problem. We started the machine after the weekend and this error code comes up during initialization. F-MOT-MSETDYN X/12: Position counter dead MyData tells us our only option is to have a service call, which may be necessary, but I would like to make sure that we didn't just unplug something or have something stuck where it shouldn't be. Any suggestions??? Thanks. Thu, 11 Sep 2014 17:23:05 GMT Do you use hammers on your machines ? Just so you know, it is completely normal to whack the leveling feet of brand new machines with a 3lb ball peen hammer to adjust the machine in the line. The machine was moved several inches using this method. Brand new 180K+ machine. Factory FSE was doing this. I asked him if he though this was a good idea. His response: "We do this all of the time" All I have to say is WOW..... Thu, 11 Sep 2014 17:13:46 GMT Possibility of a cheaper pick and place machine design? Hi (I don't know if this forum is the best place to post something like this, but I don't know of other places on the internet, so... sorry if I'm in the wrong place) Might there be an easier way to add components (e.g. computer chips) to a circuit board? I'm mean a slower but maybe more convenient machine. First, put a small magnet on the circuit board. The small magnet can be moved around by if we pull it with a large magnet underneath the circuit board. The large magnet underneath may be mounted to moving parts, controlled by a machine. Second, drop a computer chip on the circuit board. Using a video camera, a computer program can locate the chip, and push the chip to it's correct location by moving the small magnet, using the large magnet. Once everything is in place, you could keep spraying the circuit board with glue until all the chips and other components sinks in. Note... Maybe the small magnet should have low friction, because it presses against the circuit board and you don't want it to scratch the circuit board too much. Maybe the small magnet should be shaped like a cross or a hash so it can push components easily. Maybe it can have four "hands" which look like-- . . \ . . . .\____________________ . . . . ____________________| . . . ./ . . / (a funnel) so that it can move many components at a time. Maybe the inner walls of each "hand" can have high friction, so some components will get stuck and each "hand" can only be unclogged if the magnet moves in a specific angle. The inner wall friction is equivalent to a grab and release ability. When it is finished with one circuit board, the magnet can push it off the workarea and pull in the next circuit board from a stack. The magnet could climb on and off the circuit board using a ramp with a flap. To pull in the next circuit board, it may hook to a rubberband or string band that's taped to the circuit board. When it runs out of chips/components, it can also pull in more components (in paper trays) from outside the workarea. The process might be very messy. Most components may fall off the workarea, so many trays of components are needed. Another problem is that bits of glue may miss the circuit board and hit the workarea instead. Perhaps a sheet of paper should cover the workarea. Also, the magnet may stay clean by taking cover under a tent. Another problem is that some computer chips and other components may be attracted to the magnets... perhaps in those cases the magnet can still push them from a distance, using a long shovel as a tool. The magnet might be able to wield another useful tool: the silver ink pen, for drawing circuits on boards. How do we hold the pen upright? Perhaps we can give it "training wheels" like the ones on a bike--except longer, and with tiny wheels. One possibility: the magnet holds the pen tip deep inside one of its "hands." Also in the "hand" is a small ramp. To draw a line with the pen, the magnet simply pushes the pen; to move the pen without drawing a line, the magnet moves in a special direction to push the pen onto the ramp. Finally, the most difficult components to add will be push buttons. How do you spray a sea of glue on one without jamming the button? Maybe instead of gluing down the button directly, you could surround it with hood shaped plastic parts (made by 3D printers), and glue those down to secure the button. To prevent any glue from falling on the button itself, maybe you can add a 3D printed umbrella tent to cover it. Will the suggestion work?
