Thanks Evtimov. I was actually looking for both. 1. Cost per placement For SMT: Your proposal is the following? (Hourly labour rate of operator + hourly machine & maintenance cost + hourly utilities cost) / # of components placed per hour 2. This

You see, if you can optimize your product setup that will be the best. Back in the days, engineers used only standard values. For resistors for example I used to build boards having 100, 330, 470, 1k, 3.3k.....Sometimes that means you might end up wi

Yes, we ended up with VisiConsult. Technical support is A++ and I really like the simplicity of the software interface and the counting cloud. Anytime you run into a shape that will not count correctly, you take several x-ray photos and upload them

Hello friends, I'm looking for hints where to buy metal/steel sheets for stencil cut. Worldwide. Different quality, thicknesses and surface treatment.Size 23x23, 29x29. I heard there were some good quality metal sheets suppliers in Finland, Japan, M

This problem frequently becomes an issue with lead free solder paste, because it has very different rheology than leaded pastes. While not a 100% of the time, the squegees are very ofen the cause. When the regular blades are used (steel squegees), th

One of the reasons I am looking at older AOI inspection systems is I suspect they are more primitive and easier to use. No instruction manuals needed. I watch this video and see how easy it is to use/program: https://www.youtube.com/watch?v=8BZlb

http://www.aoisystems.com/ I was at the SMTA show and saw this company's booth. It looked like a good product at a good price but it doesn't do 3D AOI. The sales person was saying that 3D AOI is only useful in cases where a lead pin is hanging in

That's incorrect. 3D aoi is extremely useful for determining solder flow and slope which a 2D can't do. Yes it's also great for coplanarity, tomb stoning, head and pillow and a multitude of other defects. Most 3d AOI use cad models and height measure

My pick and place machines are 10+ years old so I might be in the crappy department. I wasn't looking for a complete fool proof system, I am looking for aoi on a tiny budget that covers majority of scenarios. We will have to be mindful of solder sl

We have some fairly standard 0.1" pitch, two row, shrouded, through hole headers soldered onto a thick backplane. There are tiny inspection holes along the bottom edge of the plastic body that allow an inspector to observe the top of the through hole
