Cutting tape can get stuck in the feeder, and reel assemblies tend to avoid jamming. Tape packaging solves a handful of issues when considering component handling: Components can be fed into a Pick And Place Machine for board assembly. Then, if you look at a mini-reel and estimate from the scale that it is roughly at its 60% marking, and the quantity of a full mini-reel was calculated as 1300, a quick calculation will result in an estimated 780 components remaining. One such example is today's placement machines that are capable of picking and placing thousands of components per hour with extreme accuracy. It is compatible with the standard 7" reels, only smaller. The most accurate estimate is when using a Reel Quantity Calculator.
