Shear tests are [in my opinion] senseless. The shear stress you measure depends more on the shear rate and on the point where the force is applied than on the grain structure. When shearing a component, you not only apply shear stress, but also roll

after checking two computers, did not find it. However after using "google" found it in a flash. (less than 0.22 seconds) using a spreadsheet. how about this for resistor & capacitors with 4mm pitch, all measurements in millimeters. cell A1 "input

Does anyone know how to make the vision alignment work on a Quad 4C? What I mean is make it work right, and reliably. I know how to define the component for inspection (lead pitch, lead count, dimensions, tolerances, etc.), and I know how to set ligh

I seem to of slipped into a mighty giant suction cup, and every day is the same. Now take yesterday as I was making a sample the start of run board, we have run many times. it got halfway placing diffused LED's 3216 (about 1207 size) then is stoppe

I don't think it is a loose camera lens. We are actually off on the position of the Z-rod. It's not just the camera position that is off. We really can't change nozzles because the z-rod misses the hole in the nozzle changer. We have repeatedly clea

We have HRFT-301U ( staple bend) is fairly easy to set up. All you need is t-handle Allen that I believe is provided with the machine. All adjustments to form a part, both pitch and lead length are mechanically adjusted by sliding the forming and c

I am not that familiar with the older systems. The software should be supported on both old and new alike unless you are limited by the operating system, but the camera will obviously have a lower resolution and perhaps the filtering is not quite as

We have a Heller 1707EXL that we use for lead and lead-free production. It has both a mesh belt and edge rails. We run 90% of our assemblies on the mesh belt (leaving the edge rails wide open). I have noticed when profiling a board on the mesh bel

Generally the heller exl range has issues in cross profile, some machines more than others. I have see as bad as 15 deg c and as low as 5 deg c ranging from entire length to a few zones. They never match the specification in reality. The markiii is
