I'm the AOI operator here, and no, we do not look at DNI locations. It was considered, but overall, the extra time taken is not worth it. You could inspect some locations where components are not to be fitted, but I guess it depends on how many place

| Anyone know a independent PCB inspection of BGA (X-Ray). We have several test boards that need BGA inspection. For detailed analysis try X-Tek in Santa Clara, Ca. 408/486-9620 or you can rent the RTX from Glenbrook Technologies for $950 per week 2

We've got prototype 6-layer PCB's and I suspect that mfg. swapped some internal layers. Would it be possible to use some form of x-ray inspection to verify that? Any ideas?

Hi Deni, X-ray will not be able to see through Power and Grn planes. Your only way to find out is: 1) ask your board supplier to supply stack up used. 2) surface grind layer by layer to validate if it is correct stack up. What is making you think

Dumb question maybe but does the board have a layer count window? Usually each layer has it's number visible in copper somewhere on the board and the shop will leave the solder mask clear of this window. If the layers were stacked incorrectly it woul

Having no real experience with x-ray inspection, this answer helped a lot. What I actually want is to check top 3 layers and it should be pretty straightforward, as the second layer from the top should be almost empty and the third one should be a gr

You would be suprised what you can see with even a simple Xray machine. The engineers upstairs wanted to see if the xray could confirm there was an open via on a thin dense board with several layers. I thought (but didn't say) no way. But with carefu

I have a question about inspection, touch-up, and how far you need to go to get a product that meets the required IPC-spec. According to some reports (i.e. "New Study Reveals Component Defect Levels" by Stig Oresjo of Agilent) the average defect leve
