Component orientation into the reels | 1 March, 2001

Are there some standards (Jedec ??) for the components orientation into the reels (memory or logic) and which ones ?

Thanks

Last time we looked at this, JEDEC carefully designated the dimensions of the carriers, but "neglected" to define the component orientation with the carrier.

Go to http://www.jedec.org/download/, search for JEP95 JEDEC REGISTERED AND STANDARD OUTLINES FOR SOLID STATE AND RELATED PRODUCTS: This publication is a compilation of some 1800 pages of outline drawings for microelectronic packages including transistors, diodes, DIPs, chip carriers and package interface BGA outlines in both inch and metric versions
