SPECIFICATION FOR BARCODE MARKING OF INTERMEDIATE
CONTAINERS FOR PACKAGING MATERIALS
This standard was technically approved by the Global Assembly & Packaging Committee and is the direct
responsibility of the Japanese Packaging Committee. Current edition approved by the Japanese Regional
Standards Committee on July 23, 2004. Initially available at www.semi.org September 2004; to be published
November 2004. Originally published in 1996.
1 Purpose
1.1 This specification describes a common format,
content, size, and location for printed, machine-
readable labels on an intermediate container of
materials used for semiconductor packaging.
1.2 This specification provides for a smooth transition
from existing traceability and labeling procedures to a
comprehensive, unified system envisioned for the
future.
2 Scope
2.1 This document applies to the following packaging
materials:
2.1.1 Leadframe
2.1.2 Molding compound
2.1.3 Bonding wire
2.1.4 Die attach materials
2.2 This document applies to only the intermediate
container. Barcode specification for shipping pack is
referred to EIA 556A or EIAJ barcode specification.
2.3 This document does not apply to product package
label.
NOTE 1: There are requests for labeling on product packages
from the customers. However, task force concluded that the
product package label was not included in scope of the
specification because of limitation of area to be labeled on the
package. For further activity, two-dimensional barcode
symbol may be needed to standardize the barcode marking
specification for product packages.
NOTICE: This standard does not purport to address
safety issues, if any, associated with its use. It is the
responsibility of the users of this standard to establish
appropriate safety and health practices and determine
the applicability of regulatory or other limitations prior
to use.
