When x-ray inspecting BGA packages with metal heat spreaders tube voltages greater than those used for Plastic BGAs must be used. It must be recognized, however, that the tube votage required will depend on the particular sensitivity of the x-ray cam

I am hoping that someone can help with this. Am attempting to source "used"/refurb 130kv Hamamatsu x-ray tube and controller (for a CR Tech machine). Am having difficulties in locating a source. If anyone has any ideas, it would be greatly appreci

TL IPS: I am having problems replying to you directly. Here is the info on the X-ray machine in question. We definitely need to replace the tube and controller. We are not "hell bent" on a Hamamatsu replacement. If you have something else availa

These are inexpensive radiation monitoring devices and it is possible, when they are calibrated to a Cesium-137 standard (at 600 keV), for the meter to read higher than the actual value at lower x-ray photon energies. [Glennbrook Technologies Caution

Hi, Can you tell what model system this is for? Hamamatsu tubes are not easy to come by as a rule unless they are new. How much are you looking to spend? The new 130kV Hama tubes go for ~$25K. Are you sure that the controller and the tube are bo

Juan, Try Hamamatsu directly. (908) 231-1116 e-mail: usa@hamamatsu.com Ask for "RE-LOAD" pricing. Make sure you have the tube serial number and model available. Some units cannot be re-used. You will find the serial # on the side of tube housing. J

To best visualize the factors effecting resolution, carry in your minds eye an image of a light shadow being cast on the wall using a flashlight. The size of the flashlight filament would be the analagous x-ray "focal spot" The smoothness and/or roug

Melf components are tube shaped so the X and Z values are the same. If you use 3D X-ray you can tell if the joint is attached to the board properly and you will not need the Z-dimension information. This might be a better longterm solution than usi
