1 Scope
This test method defines the procedure for deter-
mining the adhesion of solder resists (masks) used over melt-
ing metals, (such as solder plated and reflowed solder printed
boards both prior to and after soldering), nonmelting metals,
and printed board substrates.
2 Applicable Documents
Solderability Test Methods for Printed Boards.
Design Standard for Rigid Printed Boards.
3 Test Specimens
The test specimen used shall be the
test coupon shown in Figure 1, which has the plated metal
surface that is applicable, and coated with solder resist.
4 Apparatus or Material
4.1 Tape
A roll of pressure sensitive self-adhesive film tape
1.3 cm [0.5 in] wide exhibiting an adhesive strength of at least
44 N/100 mm [40 oz-force/in] but no more than 66 N/100 mm
[60 oz-force/in] as tested per ASTM D3330, as amended. If
the tape has an advertised expiration date or shelf life it shall
not be used after the expiration date. If no such date exists,
the product may be used up to one year from date of pur-
chase. A noncomprehensive list of tapes meeting this require-
ment can be found at ‘‘Pull Test Tapes’’ under ‘‘Technical
Resources’’ at the IPC web site: www.ipc.org.
5 Procedure
5.1 Preparation
5.1.1
For qualification testing, test specimens are to be pre-
pared by processing 34.0 µm [1,339 µin], double clad epoxy
glass laminate through the standard plating process for the
metal coatings that are applicable. For production testing, the
coupons shall be representative of the board.

5.1.2
For preproduction qualification, test specimens are to
be cleaned using cleaning methods as recommended by the
solder resist manufacturer and standard production methods
for comparison purposes prior to solder resist application.
5.1.3
Test specimens are to be coated and cured by the
standard production method.
5.1.4
Testing is to be conducted on specimens before and
after soldering in accordance with J-STD-003, Methods A, B,
C, or D with no accelerated aging.
5.2 Test
5.2.1
Press a strip of pressure sensitive tape, 50 mm
[1.97 in] minimum in length, firmly across the surface of the
test area removing all air entrapment. The time between appli-
cation and removal of tape shall be less than one minute.
Remove the tape by a rapid pull force applied approximately
perpendicular (right angle) to the test area. An unused strip of
tape must be used for each test.
5.3 Evaluation
5.3.1
Visually examine the tape and test area for evidence of
any portion of the material tested having been removed from
the specimen.
5.3.2
The report should note any evidence of material
removed by this test.
6 Notes
6.1
Figure 1 illustrates the coupon that is used for testing.
The black squares indicate metal. The white squares indicate
the base material. Solder mask is applied over the entire con-
ductor pattern.
6.2
If foreign material (oil, grease, etc.) is present on the test
surface the results may be affected.
6.3
Certification of 3M Brand 600 1/2 inch tape to CID-A-A-
113 is not required. The 3M Brand 600 1/2 inch tape is avail-
able through most office supply stores.
