Thomas, We evaluated several AOI machines and narrowed the field to two, YESTech and MIRTEC. We had an opportunity to work with both of these machines on our production floor. In our experience, the MIRTEC machine simply outperformed the competitive

Start with targets based on the stencil thickness (for height) and stencil thickness times the aperture size (for volume). * Set reasonable upper and lower control limits (+ 25% and –25 % of the targets, for example). * Next, check the printer set-u

You should just be running you Kic or Mole to verify the process.Every new board should be profiled. Once have verified the process there should be no reason to keep prifiling the boards. Your QA dept should be inspecting the solder joints. If there

We are a low to mid range manufacturer as well. I looked at several different vendors incuding; Mirtec, Viscom, Marantz, Omron, VI Tech, Orbotech and Yestech. We selected Mirtec. As a mid range manufacturer, one of my main concerns was quick and eas

I am looking to send a couple of employees to take some focused training in six sigma. It would more than likely be at the beginner level, overview to green belt. We are a smaller contract manufacturer and want to implement more use of six sigma me

Thanks for the comments so far. The smallest nozzle I've tried is a 4mm, which is what Pillarhouse used on this board to provide a sample. I tried this but wasn't as good as the 6mm. I've soldered the same connectors on a different board using a 10mm

Ok we have to admit that for some reason you went for the used machine, but the $6000 are worth it, I have 2 of the same machine without the NG marker, and in 4 years (the newest one ) and like 6 o more of the old one, there have not been a mech prob

In agreement, in that you should have already printed enough paste on the board to accomodate the joint. Adding paste would give the result you described. (too much solder) Adding a little flux (only) and heat would be the correct path out of that s

If they're 1 1/2 years old, they are definitely aged parts. Either send them back for newer or widen your tolerances on the ICT to compensate. You are at the 3rd decade now (10,000 hours) and you will need to compensate for this. These parts are n
