This is getting deep but here's my input: Here's an idea....... Get a full reel and weigh it on a parts scale down in the stock room. Next weigh an empty reel. Subtract empty from full, and devide this value by the quantity of the full reel. This

Buy an electronic counter and simply spool your partial reels to an empty reel. It takes my staff a couple of hours to count every component on partial reels (~50 different values) and I have an exact number rather than an estimate.

I just had a better idea, why not make your own template. A cylindrical guage printed out on a piece of mylar. A series of concentric rings with a quantity on each ring. Use it as an overlay.

Hi Greg, I have the same idea, but my dilema is reel come in different size, thickness, pitch...etc. Did you make one up? could you share those information with me. Thanks, Eugene

I was wondering if anyone knows of a tool, like a depth gauge, that is designed to measure the component count of partial SMT component reels. Most reels have a built in indicator gauge, but several do not. A tool would be handy for our physical in

I feel an SMTA vision award coming on. A depth guage sounds like a great idea (especially one designed specifically for that purpose). It should readout "components remaining". But until that product is avaialble, why not just save some of the empt

We use this for our measurements: N=(17000(D^2-d^2))/(C*P) N=number of parts on reel D=OD of carrier tape on reel (inches) d=OD of reel core (inches) C=thickness of carrier tape (mils) P=pocket pitch (millimeters) example: 6"OD on 3" core of 40-mil

That is true. But maybe for discreets in paper tape where the bulk of your partially used reels is it may be helpful. The rest you can guestimate. Not very good of course. As a placement machine manufacturer I agree every machine should have real

This tool is what you want, been using them for 9 yrs or so and am very happy with there product. http://www.vtekusa.com/pc250.htm
