SMD assembly JEDIC tray orientation:
     
We would like to know how other companies (users) handle the situation of 
suppliers of fine pitch SMD components not supplying the components to one 
standard orientation (REF OLD JEDIC STANDARD PUB.95, C0-15 (PQFP))?
  EIA-481 (tape and reel) is an accepted, abided by industry standard
governing items such as orientation.Why is there not an abided-by  industry 
standard for fine pitch? Are others of you having the same trouble we are 
getting different vendors of fine pitch to supply parts in the same 
orientation? Is there another industry standard out there we are unaware of? 
Please share some opinions!
     
Thank you,
Jeff Hempton
