NOTICE
JEDEC standards and publications contain material that has been prepared, reviewed, and
approved through the JEDEC Board of Directors level and subsequently reviewed and approved
by the JEDEC legal counsel.
JEDEC standards and publications are designed to serve the public interest through eliminating
misunderstandings between manufacturers and purchasers, facilitating interchangeability and
improvement of products, and assisting the purchaser in selecting and obtaining with minimum
delay the proper product for use by those other than JEDEC members, whether the standard is to
be used either domestically or internationally.
JEDEC standards and publications are adopted without regard to whether or not their adoption
may involve patents or articles, materials, or processes. By such action JEDEC does not assume
any liability to any patent owner, nor does it assume any obligation whatever to parties adopting
the JEDEC standards or publications.
The information included in JEDEC standards and publications represents a sound approach to
product specification and application, principally from the solid state device manufacturer
viewpoint. Within the JEDEC organization there are procedures whereby a JEDEC standard or
publication may be further processed and ultimately become an ANSI standard.
No claims to be in conformance with this standard may be made unless all requirements stated in
the standard are met.

TEST METHOD A109
HERMETICITY
(From JEDEC Board Ballot, JCB-11-71, formulated under the cognizance of the JC-14.1
Subcommittee on Reliability Test Methods for Packaged Devices.)
1 Scope
Testing for hermeticity on commercial product is not normally done on standard molded devices
that are not hermetic. Commercial product that this test method applies to has a construction that
produces a hermetic package; examples of this are ceramic and metal packages.
Most of these tests are controlled and updated in the military standards, the two standards that
apply are MIL-STD-750 for Discretes, & MIL-STD-883 for microcircuits. The test within these
standards can be used for all package types.
Within these standards the tests are similar; MIL-STD-750 Test Method 1071 Hermetic Seal is
recommended for any commercial hermetic requirements.
For MIL-STD-883 the applicable test method is 1014 Seal.
