Hi Dub J, I have worked for a few companies that did 3D sampling and found the data they produce to be useless. In the real world they are slow, so that means you won't sample every board. Now if you're not sampling every board, and you start to r

Hi Steve-O, Good question(s). This process was set-up by an engineer that had a PhD in statistics, took him a year to develop and then thru it over the wall at us. The biggest problem we saw was SPC to measure solder volume. SPC is good for measu

Hi Mark, There are many tools available for measuring solder paste height. Most machines use laser as the basis for inspection while others use structured white light. If simple height and width inspection is all that is required, you can look int

I think I had my units wrong in my previous post - that blueprint job was 6 years ago and fading fast. My level of 700 would have the same units as Dave's level of 1000. This is the metric measurement of lux, vs the imperial footcandles. fc to lux

We have a new SMT line, our customers are asking us the validation of the process. Not only the validation of the resulting assembled board (solder joint...) but also a validation of every single machine in the line (ex. stencil printer...). For exam

It isn't an FDA validation. I think Steve has centered the problem. I have already defined all the steps and all the procedures of the process, but now I must run X boards, Y times, through each piece of equipment (as he said before); the question is

I suggest that you perform a electric power quality analysis with a qualified technician using this equipment https://www.fluke.com/en-us/product/electrical-testing/power-quality/1742-1746-1748 test 1 : all lights on take the measurement of your s

Hi, I think the standard was IPC 6850. But I will recommend to go directly with the sigma test. Place parts with the machine and measure the placement accuracy on another machine. 4-5sigma at 50um should be a good machine. If they have sigma in thei

Hi Alexei, We have met in the past ( simona - > PCB ) Thank you for this input, I might consider > it ! Hello, validating a whole line can be tricky. I can advise you to validate each machine (not the transports) and then put them together in one
