John,

This spec does not have specific information on standard quantities.
It covers issues like how loose components can be in the Carrier Tape
cavity, specifies standard Carrier Tape widths, the dimensions for the
sprocket holes, defines standard Reel sizes, tape leader and trailer
lengths, etc.

Since there is practically an infinite number of different surface mount
electronic package styles, and the quantity of parts that can fit on a
Standard Reel size depends on the component's length or width, and height,
it is probably outside the scope of any organization to define a Standard
quantity of parts per Reel for all packages.

The number of components is up to the individual supplier/customer.

Folks,

I do not have a copy of this EIA 481-2 standard, but can anyone tell me if
this spec contains information in relation to STANDARD quantities per reel.
i.e: If I order a reel of 44 pin QFP's from a supplier who adheres to EIA
481-2, does this require them to put a particular amount of components on
the reel, or is this up to the individual supplier/customer?

Thanks for your help,

John
