I am an engineer assigned to resolve a quality issue on our production line. It seems that we have been getting small droplets of flux on our boards after the reflow process. Occasionally, they land on a board to board connector and that can cause an open under certain conditions, even months or years later in the field. I ran a test with bare boards to verify that the problem was not a "global" problem. i.e. resident flux circulating in the oven itself. The splatter only occurs locally on the board. I read that the profile used for the ovens determines the amount of flux splatter that can occur. So we change that once to see what happens, but not much difference. However there is more work we can do there. We also noticed that this occurs on several of our lines, but the residue doesn't affect most of our products. Some say to put kapton tape on the connectors and remove it afterwards. However I can't see how you do this on a manufacturing line affectively. I have yet to find anyone that does this. Any thoughts or war stories would be appreciated.

Since there are so much of different companys, we took already 3 of them into the inner circle. What are your experiences whith these 3 Systems? I believe SPI's are all good, but which on is the best 3D AOI, regarding less false, 1st run, 2nd run success rate, mtbf and offline setup time? We want to install the system inline. But since we have normally small lots, we need especially flexibility. What's your opinion? Which system would be the best. Do you have seen any previous benchmark results of these 3 systems?

Has anyone got any recommendations or seen anything similar? Regards Adam Wed, 03 Feb 2016 17:08:08 GMT Homebrew Stencil Printer Vision, Completed I completed the stencil printer vision project that I started a few weeks back to add a vision system to my Dek249 printer which did not have any vision. I used a cheap pc and two monitors, two dual-monitor brackets and two USB pen cameras, all aquired from ebay for as cheap as possible. I made up some brackets to mount the monitors and welded up an arm to mount the cameras on. I dedided to use a dual-mount monitor bracket and modify end-of-arm to fit my cameras; I may change this to two independednt single mounts that can be moved along the arm for more flexibility. Then I wrote a simple application that displays the video from the camera on the screen with the ability to capture and overlay a still image with a few filtering options. I find a negative image with red tint works best. The good news is the Dek249's plate returns home to the same postion each time. The subsequent boards are very easy to align with the images prior to printing so it turned out pretty well. If anyone wants the software I'll be happy to share it.

Machine Computer, Station Computer, and Line Computer. There appear to be two computers in the HS50, one windows based and the other SBC VME computer, I'm assuming Unix or similar. Can someone tell me what is what and if they are located in the machine or external. The two computers do not appear to be connected, do they need to be connected via Ethernet cable? We can't seem to get past 'Software Booting...' we also get a server not found error. Thanks for any advice you can suggest.

Wed, 27 Jan 2016 22:03:14 GMT Questions about automatic X-ray inspection (AXI) machines. We do High Mix, Low Volume and are looking for the best inline AXI with the criteria of industry-leading automation capabilities. The abilities to program offline, automatic conveyor width adjustment and board alignment are important to us. We want to minimize time an operator spends at the machine and automate as much as we can. I am looking many machines and Viscom's X7056 AXI/AOI, TRI TR7600, Vitrox V810, and the Nordson Dage Xi3400 currently are the frontrunners. Also looking at machines by Apex, Glenbrook, Saki, and Scienscope. If you have any advice on choosing a machine or personally have experience with any of the machines mentioned, I would greatly appreciate your input. Also, I am wondering if 3D CT is really useful on an inline machine. It seems to me that 3D is more for debugging and failure analysis, which would be better done on a standalone machine to prevent a bottleneck in the line. Looking forward to your responses! Thanks in advance. :) Wed, 27 Jan 2016 17:32:51 GMT CAN'T OPEN ANC. invalid place position x Hi. Have a problem with a QSA 30 machine. show me a error at the end of set up program.
