ELECTRICAL CONNECTORS
FOR SURFACE SOLDERLESS MOUNTING
No electrotechnical or radio engineering device
can operate without connectors. There is a very
large variety of designs of electrical connectors
for the electronic devices, which meet almost any
customers request. Very often the connectors ensure
manufacturability issues of improving performance
of manufacturing and installation of products.
The article focuses on such properties of con-
nectors — the possibility of surface mounting with
the implementation of solderless contact con-
nections. Efficient designs oriented on batch fabri-
cation of contacts and connectors assembly are
introduced. Combining consumer needs and manu-
facturability suggests the prospect of use of such
connectors for multi-contact electronic components.
Modern connectors can contain several hundred
contacts, arranged with a relatively small interval
of about 1 mm, and naturally, the simultaneous
installation of such a large number of contacts
into the holes and soldering of the contacts may
cause some difficulties.
Importance of ensuring of manufacturability of
connectors assembly caused the appearance of
certain methods. The use of contact joints made
by press-fit (press-in) technology [1—3] improves
the performance only partially — there are no
solder joints, but mounting into plated-through holes
remains. Moreover, the size of contact connections
makes the possibilities of their miniaturization very
limited.
An original solution is the design of electrical
connectors for surface solderless mounting proposed
by the author earlier. The contact connection in
such electrical connectors is ensured by mutual
pressing of contact surfaces [3—5]. This design
significantly improves manufacturability of the
mounting and quality of the contact connection
due to large contact area. In this case, the design
The article describes the features of development, possibilities of manufacture and application of electrical
connectors for surface mounting with flexible printed cables and elastomer liners. With regard to characteristics,
manufacturability and, especially, mounting technological effectiveness, they can rival connectors with
digital metal contacts.
Keywords: electrical connectors, solderless mounting, surface mounting, design of electronic equipment,
contact joints, flexible printed cables, elastomeric liners.
of connectors simplifies owing to the use of the
batch method of forming of contacts on a flexible
printed cable (FPC). Pending this work the task
was set to develop various types of electrical
connectors designed for application in a variety of
electronic devices with the use of FPC and elastomeric
spring liners for solderless surface mounting, as
well as to determine characteristics of such connectors
experimentally. This article describes the results
of these studies.
DESIGN OF ELECTRICAL CONNECTORS
The developed connectors are included to the
group of low-frequency rectangular direct joint
connectors, so in fact they consist of one part — a
socket, while the terminal contacts of PCB of elec-
tronic modules or other similar structures serve
as a plug.
The basis of the connector is made of contact
groups manufactured according to the technology
of flexible printed cables, and elastomeric liners,
which function as group springs for contact elements.
Fig. 1 shows an electrical connector which is
designed with the use of above-listed elements [6].
The plug is located in the rear part of the
PCB 1 of electronic module and includes printed
circuit contacts (lamellae) 2 and the slot 3, which
serves for the precise junction with the socket. The
socket consists of a body 4 with a working cavity 7
and a bridge 6, a cap 9, made of plastic, an elasto-
meric liner 13 and an FPC 5 with printed contacts 8.
For fixing of the socket on the printed-circuit back-
board there are latches 14 and fixing pin 10 with a
hole 11 in its rear part for fixing the socket, for
example, with a cotter pin. There also are pins 12,
which are used for accurate fixage of the sockets on
the PCB.

NEW COMPONENTS FOR THE ELECTRONIC EQUIPMENT
FPC is inserted into the socket body. FPC con-
tacts project from the body in two planes: in one
they contact with the PCB of the electronic module
and in the other — with the printed-circuit back-
board, as it is shown in fig. 2.
The junction is formed as follows. The plug of
the PCB of the electronic module is inserted into
the working cavity of the socket, and the rail
bridge of the socket body enters the guide groove
of the PCB, thereby providing an exact match of
contacts. As the working cavity narrows, the
distance between the FPC and the left wall of the
body at a certain depth of the cavity becomes less
than the thickness of PCB of electronic module,
which ensures a reliable contact junction. At the
same time the elastic liner acts as a group spring,
creating a constant pressing force for contacts. Thus
a gas-tight contact connection with a large effective
contact area is formed.
The electrical connection between the socket FPC
and the backboard with the use of the above-
mentioned elastic liner is formed similarly in a
different plane.
TECHNOLOGY FEATURES OF ELECTRICAL
CONNECTORS BASED ON FPC
AND ELASTOMERIC LINERS
Parts of connectors are produced with the use
of standard technologies, characteristic for
manufacture of electronic equipment, namely, PCB
manufacture, injection molding of thermoplastic
plastic, molding of silicone rubber. In order to
ensure low transitional contact resistance the
appropriate metal coatings must be applied on the
contact areas. It should be remembered that there
are two places of contact in the socket (zones A and
B in fig. 3): a plug connection with the PCB of
electronic module and a virtually permanent con-
nection with the backboard. The choice of coating
is determined by the use conditions.
In this case it is possible to perform a very
simple in terms of manufacturing local coating of
FPC contacts. This enables rational use of precious
metals.
A particular attention should be payed to the
method of producing socket contacts. It is similar
to the technology of producing single- or double-
sided flexible PCB, which usually applies high-
efficiency equipment. This allows to obtain any
number of contacts by batch method for an entire
connector simultaneously.
On the other hand, the manufacturing of the
FPC is possible with the use of dimensional electro-
chemical processing, which allows to receive a
double-composite structure, since there is no
adhesive to glue the foil to the insulating film
substrate [7]. Such FPC has unique operational
performance, which are determined by characte-
ristics of polyimide instead of adhesive, which is
present in all known structures of FPC.

NEW COMPONENTS FOR THE ELECTRONIC EQUIPMENT
Assembly operations for sockets manufacturing
are performed by simple methods without any
fitting.
Mounting of sockets on the backboard runs
without soldering — by clamping contact surfaces.
Mechanical fastening under certain conditions can
be carried out with the use of such an effective method
as latching and locking with a cotter pin (see fig. 2).
EXPERIMENTAL INVESTIGATION
OF CHARACTERISTICS
OF THE CONNECTORS
The connectors were studied both as a whole, with
respect to all the structure, and by the most important
constituent elements which determine quality
performance and manufacturability of the connectors.
Choice of material for elastomeric liner
Elastomeric liner being a part of the socket serves
as a group spring, which provides the necessary
pressure at the contact joints, thereby providing the
required transient contact resistance. In this terms,
a very important feature of the liner is the working
temperature range in which the elasticity and
hardness should be varied insignificantly. The
residual deformation in this case should not
considerably progress over time.
The analysis of characteristics for different
materials has revealed that mixtures based on
siloxane rubbers are the most appropriate for the
liners. Such materials are good electrical insulators
and ensure functionality of the liner in the tempera-
ture range from –60 to 250°C and at humidity up
to 98%.
The analysis of the range of above-mentioned
compounds has shown that ÈÐÏ-1265, ÈÐÏ-1338
siloxane mixtures and a composition consisting of
ÈÐÏ-1265 and ÈÐÏ-1266 mixtures most fully meet
the requirements.
To determine relative residual deformation of
components made of these mixtures accelerated tests
were carried out for two types of samples in the
air in compressed state at 100, 150 and 200°C:
— standard samples (cylinders of 10 mm both
in diameter and length);
— samples, the form and size of which match
with socket liners.
On the basis of the test results the guarantee
term for liners has been calculated, which
made 17,5 years for the selected rubber compounds.
Test results for the samples of second type are
shown in fig. 4.

pression was given by

Analysis of the obtained data considering the
technological properties of all tested compounds
showed that the best material for the liner is the

and ÈÐÏ-1266.
Calculation of the contact resistance of
connectors
An important quality index of the connectors
is the transitional contact resistance. It is not only
its nominal value that is important, but also its
possible changes during the operational process and
the tests. The most convenient way to control
the transitional contact resistance is by means
of measurement. It is impossible, however, to
measure the transitional contact resistance Rp
directly. This can be done as follows. Having used
a part of the conacts for the measurements — let
us call them the output contacts — we shall obtain
resistance Rm, which comprises the output contacts
resistance Rk and the transitional resistance Rp.
With a certain approximation Rk can be
regarded as a constant during the operational
process and the tests. Therefore, having measured
or calculated Rk, we can determine transitional
contact resistance by the formula
Rp = Rm – Rk. (1)

NEW COMPONENTS FOR THE ELECTRONIC EQUIPMENT
In order to calculate the contact resistance Rk
let us consider a geometrical model of the contact
connection from fig. 2 given in fig. 5 and its
equivalent electrical circuit in fig. 6.
The figure contains the following designations: Rkc1,
Rkc2, Rkt1, Rkt2 — resistance of base metal (copper)
and the coating (e. g., tin alloy), respectively, in
contact zones (CZ) of the backboard; Rpc1, Rpc2, Rpn1,
Rpn2, Rpp1, Rpp2 — resistance of copper, nickel sublayer
and coating layer (e. g., palladium), respectively, in
CZ on electronic module PCB; Rsc1, Rsc2, Rsc3, Rsn1,
Rsn2, Rsn3, Rsp — resistance of copper, nickel sublayer
and coating layer (e. g., palladium), respectively, in
CZ on FPC; Rks, Rps — transitional resistance of
contacts “backboard — FPC” and “FPC — electronic
module PCB”, respectively.
Given that the layers and sublayers of coatings
forming CZ have small thickness and high resisti-
vity compared to the base metal (copper foil), these
contact resistance components may be neglected.
As a result, the equivalent electrical circuit acquires
the form shown in fig. 7. This diagram can be
used for practical calculations of the contact
resistance of the connection in question.
Modeling of connectors as a current line
As large number of plug connections in modern
electronics are supposed to transmit high-frequency
signals, it is advisable to do researches on low-
frequency connectors (to which the investigated
connectors are referred) in terms of their possible
use for the transmission of high-frequency signals
(more than 3 MHz). To this effect, there has been
performed a modeling of transmission of a pulse
signals of different frequency through the contact
connections in question. For this purpose two
connection circuits and their equivalent electrical
circuits, presented in fig. 8 (X1...X6 — ñîntact
connections; R1, R2 – contact resistance, including
transitional contact resistances (R1=R2 = 0,019 Ω);
L1...L3 – contact inductance L1=L2=L3=24 nH);
C1, C2 – capacity ralative to adjacent contacts
(C1=C2=1,1 pF)), have been used [8].
The effect of contact connections as irregularities
in the current lines on the transmission are simula-
ted with P-Spice program. The simulation results
are given in fig. 9.
Analysis of the output signals given in fig. 9, a
and b, and their comparison with the input ones
allows to speak about their negligible distortion even
at ultra-high frequency (500 MHz). The results given
in fig. 9, c and d, show that the signal contacts
being surrounded by the earthed contacts allows to
improve their noise immunity to crosstalk signals.
However a dramatic distortion of the signal is
noticeable at relatively lower frequencies.
ISSUES OF SYSTEM USE OF FPC-BASED
CONNECTORS
The connector shown in fig. 1 and 2 serves as
a switching device between the electronic modules
of the first level by means of the backboard.
However, the capabities of the FPC-based connector
come to more than this. Let us consider constructive
decisions for different types of connectors.
Design of the connector that plugs into the
backboard from the outer side for external
connections and the connections between second
level modules is shown in fig. 10.
This version of the socket in the main has the
same constructive solution as the one described
above, i. e. it is mounted on the surface of the
backboard by clamping (no soldering), saving it is
mounted from the outer side. Socket 2 is connected
with other modules or with external circuits by
means of plug 3, based on a rigid PCB, on which
a ribbon wire (cable), a round cable, a harness,
an FPC can be mounted.
A possiblility for two-way connection of first
level electronic modules to the backboard with
sockets is shown in fig. 11. Such design of electrical
connections with the possibility of using two-
way access to electronic equipment allows to create
flexible layout diagrams and to efficiently use the
volume of electronic devices for arrangement of PCB-
based electronic modules.
A connecting device which is mounted on
the surface of the PCB by clamping is shown in
fig. 12. Operating principle and design of the

device are described in [5]. Connections can be
made both within a single PCB and to connect two
PCB located relative to each other in any planes.
The figure shows the connection of two circuit
boards 7 and 8 by means of such a device. For a
better perception of the image units of one PCB
are shown in cross-section.
Here we shall present a few other constructive
solutions for FPC-based connectors with improved
quality performance and greater capability.
Previously in the study the issue of selecting
an elastomeric liner material was dealt with. One
of the key external factors affecting the quality is
operation temperature increase, which makes the
residual deformation accumulate in the liners. This
results in significant weakening of the pressure
between the contacts, and, therefore, in increase
of transitional contact resistance.
For embodiments of connectors for application
at high temperatures, a constructive version of the
socket may be offered, in which, except for elasto-
meric liner, a metallic spring is used for reliability
improvement [9].
A cross section of a modified socket, similar to
that shown in fig. 1 is shown in fig. 13. If during
the operation of the connector the residual deforma-
tion is accumulated in the liner, the metal spring
compensates its waning effect.
It is possible to significantly improve the perfor-
mance of the connectors by duplicating the number
of contacts with a certain increase in thickness of
the socket. This option opens when two FPC and
two elastomeric liners are used in one socket —
bilateral arrangement of contacts, including the
terminal contacts (lamellae) on the electronic
module PCB (fig. 14).
Product design and engineering of FPC-based
connectors and elastomeric liners are realized to a
certain extent in the samples shown in fig. 15.
Here the backboard 1 with sockets 2 provides
electrical connections between first level electro-
nic modules, which are presented by fragments of
PCB 3. In its turn, the connection of the back-
boards as components of second level electronic
modules, as well as their external connection is
performed by socket 4, plug 5 and, for instance,
wire cable connections 6. Besides, the socket 4
is mounted on the surface of PCB1 similarly to
socket 2.
In this sample were used sockets and the plugs
with a contacts arrangement pitch (which defines
the dimension type of connector) of 1,25, 2,5
and 5 mm and with the surfaces of working parts
coated with palladium. According to test results,
the main parameters of the connectors are within
the range of values given in the table. At these
current values the connectors superheat temperature
does not exceed 20°C.
***
The proposed designs are oriented on batch
fabrication of contacts and connectors assembly.
The research results has shown the feasibility of
manufacturing and appliation of electrical
connectors based on the FPC and elastomeric liners,

Yefimenko // Технология и конструирование в электронной аппаратуре. — 2012. — № 4. — С. 9-15. — Бібліогр.: 9 назв. — рос. 2225-5818 https://nasplib.isofts.kiev.ua/handle/123456789/51690 621.37:621.311 The article describes the features of development, possibilities of manufacture and application of electrical connectors for surface mounting with flexible printed cables and elastomer liners. With regard to characteristics, manufacturability and, especially, mounting technological effectiveness, they can rival connectors with digital metal contacts. В статье рассмотрены особенности создания, возможность изготовления и применения электрических соединителей для поверхностного монтажа на основе гибких печатных кабелей и эластомерных вкладышей. По своим техническим характеристикам, а также технологичности изготовления и, особенно, монтажа, они способны составить конкуренцию соединителям с дискретными металлическими контактами. У статті розглянуто особливості створення, можливість виготовлення та застосування електричних з'єднувачів для поверхневого монтажу на основі гнучких друкованих кабелів та еластомерних вкладишів. За своїми технічними характеристиками, а також технологічністю виготовлення та, особливо, онтажу, вони здатні скласти конкуренцію з'єднувачам з дискретними металевими контактами. en Інститут фізики напівпровідників імені В.Є.
