Calculation method of length of carrier tape package on reel:

1. Number of meters per roll = (number of pieces per roll XP) 1000 + 1

2. Number of packages per roll = (winding area TP) x0.9

3. Winding area = Pai x r square – Pai x r square

Explain the meaning of the letters of the carrier package:

P = pitch of package carrier

T = height of package carrier

pai = 3.1415

R = outer diameter of reel

R = inner diameter of reel
