Load Factor = Board Length / (Board Length + Space) (you can get the maximum loading factor from the manufacturer, usually ranges from 0.5 to 0.9) Oven Throughput = (Conveyor Speed x Load Factor) / Length per Board

Does anyone have any industry standard yield factors to load at the component level to account for set up scrap and machine waste during production? I'm assuming there are different percentages used for each package size (0402, 0603, SOIC8, etc) but

Interesting. What changes in 1 hour? Is there any connection between the error and feeder/magazine change, load reload? Is there any other factor observed in the hour of work that is abnormal?

Check out this paper: http://www.xs4all.nl/~tersted/PDF_files/Plexus/tombstoning.pdf You can also search the SMTnet archives for more information. If you're tombstones are random as you describe, likely the problem is not with the profile; but som

| Our first article inspection after machine placement can take several hours depending on the complexity of the board. The operator visually checks the board against the drawing and bill of material. I'd be interested to hear if there are any other

Forget what the machine's max. placement cycle rate is spec'd for. For each board you assemble time the actual placement rate. To do this start the stop watch the instant the camera is positioned over the first fiducial on the first board, then stop

If your image is not defined properly, it will affect positioning and optimization. You can choose center, rear or front image justification. If your values are grossly off, your positioning will be off, and you may not be able to optimize properly,

Well, I know that this is not directly related to the pycom device, but the code and load cell are connected to the device so I am hoping to gain from the wealth of knowledge and experience on this forum. Until a few weeks ago, I knew nothing at all

The size/type of screw and its preloaded torque are determined by the type and intensity of the load being applied to it. This should be known or estimated by the engineer that designed the product. Then they'll typicly apply a large safety factor

I have some questions on this. What is the power rating of the power supply? In power supply where are you using the capacitor? What type of loads you connect to the power supply? If it is a simple 50Hz rectifier, There is no option. You have to us
