Machine design plays a major factor in actual placement rate vs. the published tact time max speed. For example, random access horizontal turret head machines can vary greatly depending on nr. of different components and size ranges, while the dual g

This is highly dependent upon your board, vision inspection, part rotation, part type, layout, number of P/Ns per (1 pers or 100 pers) feeder layout, optimization, nozzle changes, etc... all have significant impact on placement speed. I find if you

I used to use CircuitCam and switched to FactoryLogix for a couple years now. We absolutely were able to upload our .cpf files and didn't have to reinvent the wheel so to speak. I'm not tech support from them but I can at least verify you are doing

Sounds a little tough to achieve. Math isn't my strongsuit but...If you run a million parts through the machine, you will have 200 feeder exhaust's (assuming 5000 per reel). So if you have your machine error out after 3 attempts/misspicks you will ha

My chipshooter will not "Time out", it will try to pick 3x and then alert the operator. Which would be 3 misses per empty reel. Unless I misread his post, he said 500 ppm at the placement machine. That makes a big difference.

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,

We design PCBAs. Our CM assembles the boards for us. So far we have used waterwash SMT process to build the boards. Accidentally, due to documentation errors, we suddenly have a huge batch of boards built with No-Clean process. Although the boards pa

It means the machine places another component, no missing PCBs are built. As an update I have measured this % in the newest machine and it is below 1%, but in our worst machine (old quad) it is as high as 9% for a small batch of 10 boards (~15 comp p
