Maintenance on the lightning heads is extremely minimal, especially compared to the absolute mess that is flexjet. They just go. Also, you can replace a whole spindle with a new one for something like $700, it only takes a couple minutes and you do

Hello All, I'm looking at performing a cost analysis to calculate cost per placement at SMT. I've read articles and many suggest simplifying it to labour cost (hourly rate x # of operators) / # of placements per hour. Other angle to this is evalua

Now you are going too deep. Purchasing should have nothing to do with your placement cost. Reducing part numbers too. These are separate processes and should be evaluated separately. You have: 1. Machine time and cost -utilities -maintenance -consu

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

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
