Thank you for the answers to my questions. We are running two-lead LED insertions. Most of our PCBs are square between 9" and 14.25" in a 16 x 16 array, so pitch ranges from 0.52" to 0.90". Further complications are that most of the boards have th

Hello James. I've got a YesTech YTV-2050 system at work with one top-down camera, and 1 side-view camera for each of the four sides. I do have the side view cameras being used for automated side inspection. There are some parts with markings that are

Another thing to make sure of and the vision calibration system will fail if this is out of range: Use a magnet foot stand micrometer and measure the spindle run outs. First remove the nozzles and nozzle adapters, then put the adjustable tip (I dont

Yes, mostly. The computer just has a setting for which size frame it is in (66, 84 or whatever). The bearing slider is almost certainly the same, too, although the rails are a different length. As best as I can tell, my 1306/20 (which is NOT a III

I get the MCV thing. I dont see it spelled out anywhere when it says each component is to be treated singularly. To me �...a maximum concentration value of 0,1 % by weight in homogeneous materials for lead, mercury, hexavalent chromium, polybrominate

Never heard of "special finger marker stickers" for checking wave parallelism. We assume that you're talking board-to-wave parallelism. We use a Durostone fixture with a thermalcouple [TC] in each far corner of the fixture (flush to the bottom of th

Jon, I looked it up woth NSK thats the name on it. A rep had to talk to the factory and found out it's a discontinued part. simular bearing sell between $ 80.00 and $120.00 some sell as sets two bearing and one slide , some sell just bearing, NSK

You might have to replace both entire linear rails, and then realign the axes for orthogonality. It depends on whether they can come up with a rail/slider that has the same height as the existing one. Bummer that NSK has obsoleted that rail design.

You may very well be right Hussman, but I'm not certain that marcin knows exactly what he wants to know. :) I would call that ramp rate, not delta t, but that's my language. marcin, what I'm talking about are the varying temperatures on your board d

I am in the R&D department at KIC. We have been making thermal profiling equipment for 20+ years. A standard circuit board is made from FR4 fiberglass. A typical solder reflow profile, whether leaded or unleaded, takes the board above the "glass t
