3 Terms and definitions
Add, after 3.18, the following new terms and definitions:
3.19
paper
material without conductivity in the form of a coherent sheet or web, excluding sheets or laps
of pulp as commonly understood for paper-making or paper-dissolving purposes and non-
woven products, made by deposition of vegetable, mineral, animal or synthetic fibres, or their
mixtures, from a fluid suspension onto a suitable forming device, with or without the addition
of other substances
Note 1 to entry: There are also a number of synthetic products with paper-like qualities that are applicable as
substrates for printed electronics. For the purposes of this document these can be treated as paper for testing as
substrates.
[SOURCE: ISO 21067-1:2016, A.1.1, modified – “without conductivity“ and NOTE have been
added.]
3.20
board
paper (3.19) of a relatively high rigidity
Note 1 to entry: The term “paper” may be used for both paper and board. Materials of grammage less than
2 2
225 g/m are generally considered to be paper, and materials of grammage of 225 g/m or more to be board.
[SOURCE: ISO 5127:2017, 3.3.5.2.02]
3.21
pinhole
small hole in a printed feature that is a result of a surface inhomogeneity on the substrate
Note 1 to entry: This can be a consequence of a number of causes, and potential examples are listed below:
• a small hole in the surface of the substrate;
• a hole large enough to permit the transfer of an applied functional ink;
• a local variation in the wetting properties of the surface that results in uneven wetting of an applied functional
ink.
4.2 Structures of substrates
Add, at the end of the subclause, the following new text:
For paper substrates, all paper and paper board substrates may be used. For example,
uncoated or coated one-layer paper, as well as similarly uncoated or coated multilayer
paperboards can be used, and laminated papers/boards, polymer coating papers/boards, and
papers/boards coating with extrusion/dispersion can also be used.
IEC 2018
4.3.3.3 Other materials
Replace the existing title and text with the following new title and text:
4.3.3.3 Paper substrate
When paper substrate is used as a sheet, the dimensions of the sheets shall be as specified
in ISO 216. Designation and tolerances for primary and supplementary ranges, and indication
of machine direction shall be as specified in ISO 217.
When paper substrate is supplied by a roll, the standard widths of the roll shall be according
to ISO 217. Winding length on a roll shall be as agreed between user and supplier.
4.3.4.3 Other materials
Replace the existing title and text with the following new title and text:
4.3.4.3 Paper substrate
The thickness of substrates is not limited. It shall be as agreed between user and supplier.
The method for measuring thickness shall be according to ISO 534.
Determination of grammage shall be according to ISO 536.
5.1 Sampling
Replace the existing text with the following new text:
In case paper substrates are used, the test methods in this document may be applied to the
evaluation of a single sheet or to the set of sheets. When the test methods are applied to the
set of sheets, the sheet shall be sampled randomly with no replacement. In cases where the
results of the tests are reported for a set of sheets, the total number of sheets in the set to be
tested and the number of sheets measured shall be reported.
5.3 Atmospheric conditions for evaluation test
Add, at the end of 5.3, the following new text:
The paper and paper board substrates shall be tested under standard atmospheric conditions,
at a temperature of 23 °C ± 1 °C and a relative humidity of (50 ± 2) %.
NOTE These are the standard atmospheric conditions as specified by ISO 187.
5.4.3 Other materials
Replace the existing text with the following new text:
Paper and paper board substrates need conditioning. Unless otherwise specified, the test
specimens to be evaluated shall be conditioned according to ISO 187.
8 Characteristics and evaluation method of other materials (ceramics, metal,
paper, others)
Replace the existing title and text with the following new title and text:

8 Characteristics and evaluation method of paper substrates
8.1 General
The paper and paper board substrates used in printed electronics (PE) shall be tested
according to the methods specified in Table 2. Unless there is a prior agreement between the
user and supplier these test methods shall be applied without modification. In cases where
the test has been modified, the changed condition shall be described in the report.

8.2 Surface roughness
8.2.1 General
The surface roughness of paper substrates is classified according to the following three
classes:
class (a) optical roughness at < 1 μm;
IEC 2018
class (b) micro roughness at 1 μm to 100 μm;
class (c) macro roughness at >100 μm
In traditional technology, class (a) was not recognized as an important area. However, the
progress of the technology requires the region of class (a) to be considered, whereas the
importance of class (c) m
