Introduction
1.1. General
KE-3010A/3010AC/3020VA/3020VRA, which inherit the flexibility in performance under the
modular concepts that have been built up so far in order to keep a key position of the future
flexible modular line, are general-purpose mounters with a multiple-head in an one-by-one
system that further improves the safety, reliability, maintainability and economy.
KE-3010A/3010AC/3020VA/3020VRA, having a good affinity for high-speed modular
mounter FX-3R, can construct the line that operates stably attaching electric feeders.
Moreover, KE-3010A/3020VA/3020VRA can also use the component supply unit (tape,
stick, or bulk feeders) and production program used in the existing KE series. This
permits a reduction of installation cost and a smooth startup of the system.
KE-3010A/3020VA/3020VRA is provided with an S-VCS function that permits vision
recognition continuously at a high speed, so that the tact has been improved about 61% as
compared with our existing machine model KE-3020/3020R (JUKI specified IC
Components).
Additionally, combination of this machine and floor productivity operating system to be
used with the JUKI mounters and dispensers, allow you to manage the productions not
only per line but also per floor. The floor productivity operating system manages and
optimizes the information and jobs for a whole manufacturing floor comprehensively to
provide you improved productivity, better manufacturing quality, and cost reduction.
* For details about compatibility between the existing machine models and banks, feeders,
etc., refer to "Chapter 6 Component supply unit ".
* For the detailed functions of floor productivity operating system, refer to the functional
specification of each system.
1.2. Model variations
KE-3010A: This model uses a multi-laser-head LNC60 sensor to place components
from small chip components to □33.5mm components at high speed thanks
to its laser recognition capability. When you attach an optional MNVC on
this model, image of components whose sizes are described above can be
recognized. This drastically improves the component placement cycle time
of these components, which are to be recognized with a VCS.
KE-3010AC: With high productivity and operability of the KE-3010A, it was an
easy-to-deploy unit specializing in basic performance.
KE-3020VA: This model is equipped with an MNVC as a standard device as well as a
multi-laser-head. This model can use its IC head to recognize image of IC
components such as large QFP and BGA components to place them on
boards also.
KE-3020VRA: This model has the same features as a KE-3020VA, and uses an FMLA as
an IC head to recognize various components from a small chip to □33.5mm
components with laser to place them on boards. Moreover, it uses the
multi-laser-head and the IC head to pick components at the same time to
place them on boards at the higher speed.

Features
High Precision and High Speed Placement of Components
① High-speed placement is available thanks to the new concept laser alignment sensor
(LNC60) that can recognize six nozzles simultaneously.
② KE-3010A/3010AC consists of six nozzles of LNC60 head, KE-3020VA consists of six
nozzles of LNC60 head + 7 nozzles of IC head (CDS), and KE-3020VRA consists of 6
nozzles of LNC head + seven nozzles of IC head (FMLA) that permits laser
recognition.
③ The independent AC servomotor is used to move up/down (Z axis) or rotate (theta
axis) each nozzle: this feature enables high-speed and high precision placement of
components regardless of the used placement pattern.
④ A new vision recognition system and an S-VCS function that permits vision recognition
in the non-stop operation mode are adopted, so that the vision recognition tact has
been improved.
*When a single axis is used to recognize image of a component, the conventional stop
and recognition method makes the cycle time shorter thanks to no travel distance for
recognition. (When a single axis is used, it stops and recognizes a component.)
⑤ The Flexible Calibration System (FCS), which allows a mounter itself to recognize a
component placement position error and correct it, can maintain the component
placement accuracy that is realized at the factory or control the component placement
accuracy after the line configuration is changed. (Option)
Effective tact
① Automatic tool change unit (ATC) allows nozzles to be replaced at the same time.
② A stepping motor is used for the transport motor of the IN/OUT buffer. This permits
exerting independent speed control.
Operation rate
① With a non-stop operation function adopted, components can be supplied without
stopping the mounter by automatically switching over to the pickup of the rear side
even if “no-components” occurs on the front side. (Option)(KE-3010AC is excluded.)
② As a tray component supplying device, a dual-tray server (DTS : TR1SNR/EB),
a matrix tray server (MTS : TR5SNX/5DNX) and/or a matrix tray changer (MTC :
TR6SNV, TR6DNV) can be attached on this machine. (KE-3010AC is excluded.)
A high-speed matrix tray server (MTS: TR7DN) supplies components from the left and
right tray stackers that use a new independent driving system to shorten the time
required for switching trays according to the component pick-up position. As a result,
the availability ratio for supplying tray components is improved. (KE-3010AC is
excluded.)
③ The time required for changeover is shortened and the number of component pick-up
errors is reduced thanks to the automatic teaching function of a component (supplied
with a paper tape whose component type is from 0402 to 3216) pick-up position.
④ The HMS equipped as the standard device allows you to check the component pick-up
height and to perform a teaching operation easily to prevent the operation rate from
being lowered by a component pick-up error.

Low Frequency of Failure Occurrence / Low Component Lost Rate
① Since the laser unit continues monitoring the component pick-up condition until just
before a component is placed on a board, it allows you to check whether a component
drops or not.
② The function of self-calibrating the timing of releasing the vacuum pressure prevented
the components at a placement moment from being brought back.
③ The support table that holds a PWB during the production is driven by motor so that the
PWB is unclamped without being vibrated, which means that the placed components
are not shifted. The time of clamping and unclamping the PWB has been reduced as
well.
④ When you select the high-density component placement function (Pick-up Position
Preference mode), the mounter can pick up the center of a component correctly to
prevent the tip of a nozzle from being in contact with the adjacent component when
components are already placed in the limited area.
⑤ A high-resolution (260,000 pulses/rotation) AC servomotor, although it is very small: □
15 mm, is attached on all theta axes to improve the component placement accuracy.
⑥ Use of a vacuum pump greatly improves the stability of air supply available when the
machine picks up a component.
⑦ By attaching an ionizer to the ceiling of the machine, the ion in the machine is well
balanced and static electricity in PWBs or SMT components is removed at high speed.
⑧ A stable pick-up is achieved by improving a pick-up position accuracy with an
automatic pick-up position correction function for electric tape feeders.
⑨ For components fed by a shuttle of a matrix tray changer (MTC), such defective
components as crocked legs and the like can also be collected automatically into the
original trays
⑩ As process of component measurement operation performed while Component data is
being created, components are returned to the feeder from which they were picked up
after measurement.
⑪ The production management system is provided which performs “prevention of a
component placement error” that prevents a component from being placed at a wrong
position due to a feeder-setting mistake, quality control operation such as the
“traceability” function, “improvement of the workability of preparations,” and
“management of the number of remaining components.”
Machine stability at installation
① A “Super Foot,” which is not easily affected by the floor condition, is provided as an
option.
