Knowing a devices reel size, tape width, and pin 1 orientation can help streamline the pick-n-place process.
Direction of Feed
Direction of feed is defined as the direction in which the end user unreels the tape. The direction of feed for all products is counterclockwise when the reel is held with the round sprocket holes facing the observer.
Pin 1 Orientation
Devices are reeled so that Pin 1 is oriented properly with the direction of feed and round sprocket holes. Pin 1 orientation is denoted as C1, C2, C3, C4, or M1, with respect to the direction of feed and round sprocket holes, as illustrated below.
Examples of Standard Pin 1 Orientation
*Actual orientation depends on C1, C2, C3, C4, or M1 orientation. Same package types (SOIC etc.) can have various number of leads.
