1. Formula for calculating the number of marbles and the length in meters
(1) The number of pieces per roll packaging = (wrapping area divided by (K0 + t) divided by P) * 0.9
(2) The number of meters wrapped per roll = (the number of pieces per roll x P) / 1000 + 1
(3) The wrapped area = πR2 - πr2
(4) The commonly used rim diameter is 13", inner diameter is 100, then the winding area is 77,677.
(5) The number of pieces per roll packaging = (77677 / (K0 + t) / P) * 0.9
2. Determination of carrier tape related dimensions
(1) The P-value is a multiple of 4 and greater than the maximum dimension of the same direction component by 2mm.
(2) K0 is the maximum dimension of the same direction parts plus 0.30mm.
(3) t is the thickness of the tape carrier, which is usually chosen to be 0.40mm or 0.50mm. The larger the value of t, the thicker the tape carrier will be.
