Customer-specific membrane keypads
We design and manufacture membrane
keypads and front membranes to meet
your individual requirements – if necessary, integrated in supporting plates or
pre-fitted on our enclosures.
Optimal quality can be achieved for
every use on the basis of copperlaminated supporting membranes or
strip conductors applied using the silkscreen process.
Depending on your needs we can supply you with your own individual membrane keypad with fitted touch screens,
displays and other electromechanical
components.
Printing is by means of silk-screen or
564
digital methods, according to the
number of colours and the requirements in respect of visual design.
Our membership of the specialist
keypad association ensures that we
are always up-to-date with the latest
technology, so we can always meet
our customers’ needs in the best
possible way. The membrane keypad
products which we market are components and are not subject to the
ElektroG (the law relating to electrical
and electronic equipment and appliances) or to the national laws of the
WEEE/RoHS. Consequently we are
under no obligation to register.
Technical characteristics:
Exactly to customers’ needs:
Special characteristics:
The contact elements of our keypads
are embedded between high-quality
polyester membranes.
The contact is made by pressing on
the front membrane in the area of the
key element.
On request, transparent screens (or
also coloured) can be provided in the
keypad to make visible optical displays
such as LEDs or 7-segment displays.
Of course, various glasses can also be
built in, or the front membranes can
be left clear in the screen area.
If necessary, we can fit the membrane
keypads on supporting plates or on
enclosures.
Size, design, colour, front membrane
matt, silk matt or gloss, with or without clear screen, with or without tactile
action point – our membrane keypads
are manufactured to satisfy your exact
requirements.
Depending on the type, the keypads
are equipped with a safety chamber for
each individual snap disc. This prevents
the slipping of the metal domes, so
increasing the quality considerably.

ProfiLine technology membrane keypads
ProfiLine technology optimises
the interface between man and
machine by means of the so-called
“short-stroke” feeling.
A raised key element fitted between
the snap disc and the front membrane
ensures improved tactile feeling.
This means that designers and design
engineers can give free rein to their
creative ideas when designing individual shapes and dimensions, because
ProfiLine key surfaces can be produced
in almost any required or necessary
sizes (ø 7 mm and over).
ProfiLine, the new membrane
keypad, gives the user much
more than just an input element.
The sturdy, raised keys guarantee
safe operation and provide
opportunities for personal and
individual designs.
Whether round, square, triangular or
hexagonal – the laser-cut acrylic glass
keys (recessed with front membranes)
not only give the user optimal tactile
feedback, but they are also extremely
sturdy. Thanks to the tough design,
neither excessive pressures nor chemicals have any effect on the ProfiLine
keypad. If additional safety precautions are required, metal surfaces take
care of extensive protection.
THE MAIN ADVANTAGES:
• very good tactile feedback
• raised key element / optimal
fingering
• even pressure distribution
ensures less wear and tear on
snap discs
• large-area keypad and contact
elements can be produced
• the shape of the keys can be
designed as required
• excellent value for money

EL membranes • Electro-luminescence membranes
The homogeneous light distribution of
the background lighting is a further
advantage. The electro-luminescent
phosphor particles are distributed
evenly on the surfaces of the membranes. By contrast, light sources such
as LEDs or bulbs are points of light.
The use of EL membranes in the
field of membrane keypads
offers designers many advantages.
The benefits include low power
consumption, low mechanical
fitting height, and mechanical
flexibility.
EL membranes emit homogeneous
light over the entire surface. Thanks
to their high degree of efficiency, EL
membranes are characterized by very
low power consumption. Replacing
bulbs or LEDs with EL membranes
reduces power consumption by more
than 50%.
The operating life of the EL membranes is extremely dependent on
the level of brightness.
As the EL membrane is normally manufactured using the silk screen printing
process, it is possible to produce
almost any drawing or graphic as an
EL membrane. The only restriction in
terms of design is the flat shape of the
membrane.
Increasing the voltage increases
the brightness.
The best method of increasing the brightness of the EL membrane is to increase the
voltage instead of the frequency. The
choice of colours used for the membrane
is also important. The most common
colours are green, blue-green and white.
Green and blue-green are the natural
colours emitted by phosphorus, which
means that they are the most effective.
White is not a broadband colour, and is
approximately 20% darker than a comparable green membrane. Changing the
frequency can change the colour: a higher
frequency moves the colour towards blue,
and a low frequency moves it towards
green.

Brightness (cd/m2)
Brightness (cd/m2)
In use, the membranes gradually lose
brightness. The industrial standard for the
operating life of EL membranes is defined
as the amount of time which expires
before half of the initial brightness is lost.
Membranes with a high initial level of
brightness can reach the 50% level after
only 500 hours. Membranes which have a
low initial level of brightness can achieve
an operating life of over 5000 hours. The
type of AC signal used can also affect the
operating life.
Little energy is lost in the form of
heat.
Normally, EL membranes are less than
0.3 mm thick. This offers an advantage
in comparison with sources of points
of light, which require a 2 to 3 mm
thick light guide in order to achieve a
similarly homogeneous level of light
distribution.

The surface can also be illuminated
selectively. If required, any section of
the membrane can be lit separately.
The brightness or level of illumination
of a membrane is the main factor
which determines the operating
conditions. EL membranes require an
AC signal for operation. Increased
membrane brightness is achieved by
means of higher voltages or frequencies respectively.
In order to determine the initial
brightness, it is first necessary to
establish the required lower level of
both the brightness and the operating
life.

Cu-laminated base membranes / PCBs
We offer you individual processing of your membrane keypads
and PCBs.
Cu-laminated base membranes
The base membrane of a keypad is the
lowest layer (polyester) with conductor
strips on which the snap discs for
contacting are placed. BOPLA offers
the base membrane Cu-laminated and
galvanically silver-plated, and also
gold-plated if required.
The design and manufacture of the
membrane keypads takes
place on networked CAD systems,
which guarantees speed and
accuracy.
The Cu-laminated material is highly
flexible, which ensures that there is no
possibility of breakage to the membrane cable or of silver migration or
abrasion.
570
A further advantage of the Cu-laminated membrane is that electronic
components can be safely fitted with
SMDs and soldered.
The logical result of this is FT-E technology. Its simplicity is amazing – the
input unit (FT) and the appropriate
electronics (E) are on the same carrier
material, so there are no interferenceprone and expensive connections.
PCBs with fitting
e.g. connectors, LEDs,
resistances
BOPLA offers low-cost manufacture
of the complete membrane keypad,
including PCB and fitting with simple
components (e.g. connectors, LEDs,
resistances, etc.).
Normally, the first stage is to fit the
various membrane layers and switch
elements onto the PCBs. Then the
external edges (outer profile) are
milled, and if necessary, components
are soldered onto the other side. Pins
of different lengths can be screwed
into threaded inserts which have been
pressed into the PCBs. This makes it
possible to fit additional PCBs or to
fasten the complete input unit.
This construction makes it possible to
dispense with one supporting plate.
571
Autotex AM / PC keyboards
Anti-microbial decor material
for membrane keypads and decor
foils.
Autotex AM protects against
numerous strains of bacteria,
e.g. MRSA, salmonella spp, etc.
The hard-coated polyester foil
incorporates "Microban” for
built-in anti-microbial protection. If bacteria come into
contact with Microban, its
anti-microbial function splits
the cell walls of the bacteria,
so preventing their growth and
reproduction.
Anti-microbial membrane keypads and
decor foils are primarily used in areas
where there is a danger of infection,
such as hospitals, doctors’ practices,
supermarkets, canteens, buildings
which are open to the public, and
public transport.
The manufacturer of the foil guarantees correct function during the entire
lifetime of the product. Autotex AM
is available in thicknesses 150µ and
200µ. Autotex AM does not lead to
any restrictions in design – the foils
can be designed to meet customers’
individual wishes.

Normally the external side of the
transparent front membrane is
matt. The membrane is printed
on the back, so the printing is protected against environmental
influences such as dirt, moisture
and scratches. The front membrane,
switch membrane, spacers and the
basic layer are glued together using
high-quality bonding sheets and
can subsquently be pressed if required. Pressing of the membrane
keypad is not a standard process!
It is only carried out for special
applications, e.g.:
– increased impermeability
– impermeability against alcohol

in the area where the LEDs are to be
fitted.
If embossing is not wanted, the keypad can also be fitted using an additional LED layer and a pad. Note that
this method increases the total thickness of the keypad.
In order to carry off discharges of
static electricity and to prevent the
influence of spurious frequencies,
screening can be built into the keypad. This screening membrane is fitted
underneath the covering membrane;

Circuits
a) Common conductor cable
b) X-Y matrix
Each key is connected to the common
cable and a strip conductor output.
No additional decoding is required.
All conductors are led to a highly flexible membrane cable in order to connect the entire keypad area to the
electronics.
The horizontal X output conductors
and the vertical Y output conductors
are connected to the contact points of
the keys. This reduces the number of
connections to just a few conductors.
Padding keypads
Low-cost customer-specific membrane
keypads can be manufactured on the
basis of our standard keypad range.
After selection of a basic keypad body,
the rest of the surface is filled with a
spacer. A front membrane, backprinted according to the customer’s
instructions, is then fitted over the
whole construction.

Information
Membrane cable
Slot-in pockets
Embossings
The position of the exit point and
the related length of the connection
membrane should be determined
during the planning phase. The leading out of the contact connections
is via the membrane cable.
The ribbon is punched out of the
keypad in the area of the exit so
that the membrane cannot tear
when it is bent. The standard grid
dimension is 2.54 mm. Avoid excessive bending. The ideal bending
radius for the cable is > 4 mm.
Slot-in pockets can be incorporated in
the keypad for the subsequent individual marking of keys or surfaces.
Replaceable slot-in strips (e.g. for
logos) can be inserted from the side,
front or rear. The slot-in pocket is
fitted directly behind the front membrane, so the slot-in strip is visible in
the unprinted area.
Dome embossing
On the dome embossing
the embossed area is
about 0.3 mm higher
than the front membrane.
Possible embossing forms:
Mounting holes
Plugs
If components are fitted in the supporting plate and centered in the
front membrane, take the amount of
play into consideration. The punchedout hole in the front membrane must
be larger.
The membrane cable can be led
either into one membrane direct
plug soldered to the PCB, or a plug
is crimped at the end of the cable.
If plugs have been crimped in position, a single-row post plug must be
fitted as a counter-piece on the PCB.
If the mounting drill-holes are very
close to the corner of a keyboard, the
result is thin, unequal intermediate
sections. In such cases, the corner
should be completely cut out.
Protection types
When laminating the keypad onto a
support, we recommend sealing the
cable exit with a suitable adhesive.
If the keypad is pressed onto the supports by means of a pressing device,
the keypad is absolutely waterproof
(also alcohol-proof, depending on
the design).
Edge embossing
The edge embossing is
used to guide the
fingers.
The niveau at front
membrane and key area
remains the same.
Possible embossing forms:
Bubble embossing
If an enclosure used with a keypad
is expected to achieve ingress protection category IP 65, note the
following:
The bubble embossing is
in various diameters
from 8 to 17 mm
available.
Supporting plates
The supporting plates are manufactured according to customers’ specifications.
They can be supplied with press-in
bolts with the following standard
dimensions:
1. The cable inlet in the enclosure
must be sealed with a special
adhesive.
2. It may be necessary to adapt
the construction of the keypad.

Surfaces
External contour
Front membrane / membrane
keypad
The following roughness grades are
available for the surface of the front
membranes:
1. gloss
2. silk-matt
3. matt
Matt surfaces are used in most cases.
The amount of play must be taken
into consideration when planning a
membrane keypad / front membrane
on a supporting plate or in an enclosure.
The contour can be designed according to specific requirements.
Protective membranes
Colours
Special silk screen paints for plastics –
so-called key switch colours – are used
for the printing of the front membranes. Printing is on the back, which
protects the layers of paint against
environmental influences. Standard
paints are selected and used according
to RAL.
Shades of colours according to the
HKS and Pantone scale can be printed.
Additional costs for special colours will
be charged for according to the work
involved.
Front membrane design
A minimum line thickness of 0.3 mm
must be kept to when the front panel
is being designed. High-quality printing cannot be guaranteed if the line
thickness is less than 0.3 mm.
For the front membrane design, Corel
DRAW can be provided as a *.cdr file
and used if necessary, as can vectored
Windows data.
Display glass
If required, a protective membrane
can be drawn over the front membrane or only over the screen. This
protective membrane can be removed
without leaving any adhesive residues
after the keypad has been fitted.
Glass is frequently used for screens
instead of closed, clear membranes
(front membranes).
The following materials can be offered:
1. acrylic glass (e.g. plexiglass)
2. polycarbonate (e.g. Macrolon)
3. crystal glass (e.g. window glass).
Releases
Before series manufacturing starts, a
file will be emailed, or if preferred, a
paper print-out will be sent by post for
the purpose of release.
On request, release samples will be
silk-screen printed and charged for
according to the work involved.
Assembly
BOPLA offers a complete range of
processing and assembly services.
The advantages for the customer are:
faster delivery times, fewer order
requirements, and a reduced risk of
rejects.
In this way, the customer can be certain that the keypad bonding sheet
fits the various enclosure surfaces and
that there is a high level of fitting
accuracy.

* The conductive strip resistance is dependent on the product layout arrangement. Conductive silver bridges in CuLs technology
increase conductor resistance.
Panel production
Depending on the quality ordered and
the size of keypad, we always try to
make use of the least expensive method
of production. For example, a greater
number of panel units (see photo)
would reduce the manufacturing costs
if the size of orders justifies this.
However, note that an increased number
of panel units will also result in higher
tool costs. So that we can prepare an
accurate calculation, please give us
details of the total quantity and individual batch sizes and we will prepare a
cost-optimised offer for you.

Standard membrane keypads
580
Some of the standard keypads have
been specifically designed for use with
BOPLA enclosures, so they can quickly
and easily be fitted as required.
Customer-specific types can soon be
produced at low cost on the basis of
these existing standard keypads.
The so-called black and white keypads
are used for the setting up of prototypes
and small series production. Depending
on the types, these keypads are offered
with or without marking. Some of these
keypads can also be supplied with slot-in
pockets for your individual marking
purposes.
We offer a wide range of different keys
for the design of short-stroke keypads.
The keys are designed for optimal use
behind a front membrane.
The membrane keypad products which
we market are components and are not
subject to the ElektroG (the law relating
to electrical and electronic equipment
and appliances) or to the national laws
of the WEEE/RoHS. Consequently we are
under no obligation to register.
Our membership of the Fachgemeinschaft Tastaturen – a professional
association of keypad manufacturers in
Germany – ensures that we are always
up-to-date with the latest technology,
so we can always meet our customers’
needs in the best possible way.
Technical characteristics:
Special characteristics:
Special characteristics:
The contact elements of our keypads
are embedded between high-quality
polyester membranes.
The contact is made by pressing on
the front membrane in the area of
the key element.
On request, transparent screens (or
also coloured) can be provided in the
keypad to make visible optical displays
such as LEDs or 7-segment displays.
Of course, various glasses can also be
built in, or the front membranes can
be left clear in the screen area.
If necessary, we can fit the membrane
keypads on supporting plates or on
enclosures.

Stainless steel snap disc,
gold-plated contact side
Base membrane copper-laminated
•
Safety chamber for each
individual snap disc,

•
Elegant matt front membrane
•
Dirt- and splash-proof
according to DIN EN 60529
•
The conductor strips are laminated
with copper and galvanically silverplated (gold-plated on request)
- This prevents silver migration
and abrasion
- The material is extremely flexible
and so resistant to breaking
Base membrane using conductive
silver technology
•
Graphite printing protects the
conductive silver strips against
oxidation and mechanical abrasion
•
Green insulation printing
prevents silver migration
The construction of our keypads ensures that they function very securely,
and, thanks to their good chemical
resistance properties, they are ideal for
use in harsh industrial environments.
