2 FLX2011-MKL Pick&Place

Assembly system for flexible printed circuits

and membrane keyboards

• Dispensing and placement

• Assembly of LEDs and SMD components

on foils and flexible circuits

• Manufacturing of double sides flex

modules

• Placement of metal domes

• Dispensing of two different media such

as solder pastes, conductive adhesives or

glues

• Large vacuum table

• Optional Twin vacuum table for higher

productivity

• Intelligent feeders for SMD components

• Automatic metal dome feeders

The placement machine FLX2011-MKL is a

multifunctional production cell for the

manufacture of membrane keypads and

flexible printed circuits. The machine

dispenses adhesives and solder paste and

mounts SMD components, LEDs and

switches, eg. metal domes.

The integrated vacuum table provides

space for widescreen substrates. Smaller

substrates can be clustered and processed

as one.

Assembly machines of the FLX2011 series

are designed for flexible, high quality

production and ease of use. These

machines are highly developed, based on

on the experience from more than 1,000

installations worldwide.

LEDs and other SMT components are placed quickly

and accurately. An integrated optical measurement

system checks every component before assembling.

Snap disks (metal domes) can also be placed by the

FLX2011-MKL. Various feeder types are availble for

metal domes supplied in tape or sticks.

Two different dispensing valves can be integrated.

This allows the application of two different media (eg,

glue and conductive adhesive) in one operation.

FLX2011-MKL Pick&Place 3

Universal production cell

The FLX2011-MKL can carry

out all production steps for

membrane keypads or flex

circuit boards on a single

machine.

Flexible production

sequence

The sequence of individual

production steps (e.g.

dispensing, placement) can

be chosen depending on

the process.

Large work area

The large, flat vacuum table

allows the processing of

large area films. Several

smaller formats can form a

cluster and be processed as

one.

Easy programming

Assembly data can be

converted directly from the

PCB layout data. For the

dispensing process,

coordinates are

automatically calculated by

the FLX2011-MKL using

component specific pattern.

Reliability

The FLX2011-MKL is

characterized by high

reliability and a very robust

construction. This enables

high quality production and

long lifetime.

MKL-FLX2011 with optional twin vacuum table.

On one half foils can be removed or replaced,

while on the other half foils are processed inside

the machine.

4 FLX2011-MKL Pick&Place

One machine for all flex circuit applications

Multiple individual circuits can be clustered and

processed as one.

FLX2011-MKL also places switching elements such as

metal domes.

The production cell FLX2011-MKL can

manufacture membrane keypads or

completely assemble flexible printed circuit

boards.

• Dispensing of one or two different media

• LED pick and place

• Pick and place of SMT components

• Placement of snap disks (metal domes)

• Curing with additional UV or IR modules

The work area is much bigger than on

standard pick and place machines and

covered by a vacuum table. Integrated

calibration structures assure the flatness of

the table.

Feeding systems are available for all sorts of

SMT components and LEDs, whether they

are supplied in tape, stick or tray. Other

feeder variants are designed to load metal

dome switches or labels for product

identification.

Product specific carriers are common use

for the manufacture of double sided flex

circuits. Such carriers are processed with

the foil, even in the reflow process.

LED assembly on flex circuits requires conductive

adhesives (green) and a second glue (black) assuring

the mechanical strength. The two adhesives are

dispensed and the LED is placed in one operation.

Carriers with integrated vacuum fixation enable the

assembly of double sided flexible circuits.

Single or double head dispensing system

Up to two dispensing modules are possible to combine with the mounting

head. The Dispensing valve type is chosen according to the application.

FLX2011 MKL assembly systems can be

equipped with one or two liquid

dispensing systems in combination with

the pick and place head. In one sequence

of operation thus two different media can

be dispensed and all SMD components can

be placed.

The dispenser types are chosen depending

on the application. The choices are, for

example, time pressure, archimedean

screw, jet and piezo-flow dispenser.

The coordinates for dispensing are

calculated directly from the mounting

positions and the dimensions of the SMD

components. Therefore, no additional

programming effort is required. The

sequence of dispensing and placement

operations is selectable.

Precise placement

The integrated vision system detects and

measures reference marks on the foils and

corrects any offset automatically. All FLX

assembly machines are equipped with the

Cyberoptics laser centering system. This

unique device is mounted directly on the

placement head. The measurement of

components happens "on the fly" and thus

avoids unnecessary movement to distant

camera systems. In addition, the

measurement system also detects missing

components and chip stand automatically.

Models of type FLX-V are additionally

equipped with the world's best vision

system COGNEX SMD4. It's image

processing technology uses state of the art

algorithms and reliably detects and

inspects fine pitch QFP, BGA and micro BGA

or components with specific contours.

Thanks to a unique "On-The-Fly" learning

function new component types can be

programmed within seconds.

Top-down vision for the automatic detection of

reference marks for position and distortion correction.

High throughput: The Cyberoptics laser measurement

system for SMD components and LEDs.

High precision: The reliable SMD4 Cognex vision

measures components their leads completely before

assembly.

Easy operation and programming

The user interface of FLX: virtual and easy to

understand.

The operation of the FLX2011 is very user

friendly. All information is displayed

graphically. Complex assembly data are

presented as a virtual board. Components

are shown in realistic form and size.

The CAD interface directly converts data

from layout of programs into assembly

programs. Over 300 component shapes are

already prepared and defined. With the

integrated drawing program new

components and special designs can easily

be created.

Assembly program modifications are

possible by mouse click, for example,

rotation, mirroring, moving and deleting

individual components. Layouts can be

copied and clustered.

The unique "virtual view" feature allows the

examination and correction of a program

without having to use a real component.

Therefore, already the first board of a series

will be properly manufactured.

The integrated remote control system

enables to connect the machine with a

hotline service via internet. Thus, diagnosis

and assistance of specialists is available

around the world without delay.

For dispensing, the component coordinates will be

used to calculate the dispensing dots. Therefore, no

additional programming is required.

The unique "virtual view" feature overlays the

assembly program with the live image of the PCB.

New component types are drawn quickly with the

built-in "wizard".

Feeders for all kind of components

For SMD components such as LEDs tape feeders in all

standard widths are available. These feeders can be

easily set up and can be refilled directly on the

machine.

FLX assembly machines can also place leaded LEDs.

For more information request the prochure "LED

Production" from Essemtec.

Metal domes are available in tape&reel and punched

tapes for which Essemtec has developed highly

accurate and reliable feeders.

Metal domes supplied in sticks (Nicomatic) are fed

with a special stick feeder. These feeders accept a large

variety of stick dimensions.

The flexibility of FLX2011-MKL assembly

system allows the use of various feeding

systems.

For LEDs and other SMT components a full

range of standard tape or stick feeders is

available. For short strips of tape - common

in prototyping - a universal and adjustable

tape strip feeder system can be used.

Snap disks (metal domes) can be supplied

in sticks (e.g. Nicomatic), tape&reel or

punched tapes.

Intelligent tape and stick feeders are

automatically recognized by the pick and

place system as soon as they are installed.

Therefore, the feeder status is detected

(ready, refill, stop) and indicated by means

of colored light on the feeder and also

directly in the machine software.

Feeders can be programmed offline or

online, the fastest and safest directly with a

barcode reader.
