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

This problem happens when a dark part is placed where the main conveyer stop sensor is located.The machine does a board check ( back to loading pos ) . If a part is under the sensor it absorbs the beam and the machine thinks there�s no board. The ta

Dear Distingushed Friends, I would like to gain some knowledge on X Ray. It is very Confusing for me to understand the difference between the DAGE Transmissive tube Vs YXLON micro focus tube. The Target power Vs Tube power and detailed detectabilit

You need to find a machine that has a camera with adjustable focal height. Fixed cameras can inspect most smt components but soon reach their limits when it comes to inspecting taller components like thru hole. Yes, there are many AOI machines out

In that the machine times out and waits for a feeder refill and doesn't just skip that part and leave the space empty, it's not a defect. I have found 500ppm *fairly* easily attained in SMT depending on the board mix and how you define (1) a defect,

Just so that you know, the 5DX does laminography. Like the word lamination, laminography takes a series of short focal length xrays, each a little deeper than the previous. Microlaminography allows layer by layer information to be measured in 'slic

Well John here is the situation: I need to place an infrared transistor (optical element) with a tolerance of +/-.003", this is not a problem. A lens is positioned over the optical element and snapped to the PCB via three holes that have a toleran
