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.
Inquiries, comments, and suggestions relative to the content of this JEDEC standard or
publication should be addressed to JEDEC at the address below, or refer to www.jedec.org under
Standards and Documents for alternative contact information.

TEST METHOD B107D
MARK PERMANENCY
(From JEDEC Board Ballot JCB-11-19, formulated under the cognizance of the JC-14.1
Subcommittee on Reliability Test Methods for Packaged Devices.)
1 Scope
The tests mentioned herein are applicable for all package types. They are suitable for use in
qualification and/or process monitor testing. The mechanical shear test (tape test) is recommended
as an ongoing process monitor or lot acceptance test. Electrical or mechanical rejects may be used
for these tests.
NOTE 1 This procedure does not apply to laser marked packages.
NOTE 2 The formulation of solvents herein is considered typical and representative of the desired
stringency as far as the usual coatings and marks are concerned. Many available solvents that could be used
are either insufficiently active, too stringent, or even dangerous to humans when in direct contact or when the
fumes are inhaled.
NOTE 3 These tests should be considered a destructive test unless determined to be non destructive by
previous evaluation.
The purpose of this test is to determine whether the marks on solid state semiconductor devices will
remain legible (as defined per JESD22-B114) when subjected to the application and removal of
labels or the use of solvents and cleaning solutions commonly used during the removal of solder flux
residue from the printed circuit board manufacturing process.

3 Terms and definitions
For the purpose of this specification, the following terms and definitions apply:
3.1 Solvent solution “A”
A mixture consisting of the following:
1) One part by volume of isopropyl alcohol, ACS. (American Chemical Society) reagent grade,
or isopropyl alcohol according to TT-1-735, grade A or B, and
2) Three parts by volume of mineral spirits according to TT-T-291, type 11, grade A, or three
parts by volume of a mixture of 80% by volume of kerosene and 20% by volume of
ethylbenzene maintained at a temperature of 20 °C to 30 °C.
3.2 Solvent solution “B”
A semi-aqueous based solvent, (defluxer) e.g., a terpene, aliphatic hydrocarbons, high molecular
weight alcohols, etc., or any equivalent EPA (Environmental Protection Agency) approved,
HCFC (Hydrochlorofluorocarbon), terpene or demonstrated equivalent maintained at a
temperature of 20 °C to 30 °C.
3.3 Solvent solution “C”
At 63 °C to 70 °C, a mixture consisting of the following:
1) 42 parts by volume of deionized water.
2) One part by volume of propylene glycol monomethyl ether (laboratory reagent grade).
3) One part by volume of monoethanolamine (laboratory reagent grade).
NOTE Normal safety precautions for handling this solution (e.g., same as those for diluted ammonium
hydroxide) based on OSHA (Office of Safety & Health Administration). Rules for monethanolamine or
other precautionary measures with regard to flash point, toxicity, etc.
3.4 Brush
The brush shall be a toothbrush with a handle made of a nonreactive material. The brush shall
have at least three long rows of hard bristles, the free ends of which shall lie substantially in the
same plane. The toothbrush shall be used exclusively with a single solvent and when there is
any evidence of softening, bending, wear, or loss of bristles, it shall be replaced.
