1.3 New eSW for JTF-MW
Some of the JTF-MW in the field does not have the capability of downloading the latest firmware from
machine into the control card (part number 03116629-02).
Affected JTF-MW that need to be retrofitted are from J0001 to J0043
1.4 D1-127453301 Feeder are in an undefined state after restart of the machine & D1-125647402
Unexpected reboot during feeder eSW download
In D1-127453301, the supply voltage for FCU and feeder drops down if too many feeders start their foil
drive automatically at the same time after power ON initializing.
In D1-125647402, the supply voltage for FCU and feeder drops down after start of an eSW download
Affected on all existing FCU and Feeders.
1.5 Gantry Humming/Vibration during movement
A small number of machines in the field are exhibiting humming sound during gantry movement, and
some even up to a level of vibration.
Affected machine that need to be upgraded are from E0001 to E0242.
2. Cause
2.1 New Head Board Design with Head Board Interface Plate
Several weak spots have been identified on the current board.
2.2 New Low Voltage Fusing Board Design
The observed Electrical Over Stress (EOS) damage indicates that these failures were subjected to
overvoltage/overcurrent conditions.
2.3 New eSW for JTF-MW
The control card with part number 03116629-02 is installed with an old EPROM which result that it does
not have the function of downloading the latest embedded software from the machine to the board itself.
2.4 D1-127453301 Feeder are in an undefined state after restart of the machine & D1-125647402
Unexpected reboot during feeder eSW download
In D1-127453301, a Peak current cause a voltage drop, resulting the unidentified state of the feeders.
In D1-125647402, the defect occurs with 24-56mm (non Smart) feeders only. The control board of this
feedertype is able to enter a power down mode to save power losses. Being in this power save mode,
any request of the host forces the eSW to set the standard clock rate and to switch on the motor driver
net again. This causes a current peak due to loading the capacitors of the motor driver net.
2.5 Gantry Humming/Vibration during movement
This has been identified to be related to the stability margin of the motion control of the gantry system.

3. Final Solution
3.1 New Head Board Design with Head Board Interface Plate
The board are design to be thicker and the new interface plate has optimized strengthening supports
and additional fastening locations for the board.
3.2 New Low Voltage Fusing Board Design
Replace the Low Voltage Fusing Board from FS04 to FS05 with an improved layout of the PCB and
change the component that have better immunity to negative spike from voltage (-1V to 60V) to (-5V to
60V).
3.3 New eSW for JTF-MW
To enable the function of downloading the latest embedded software from the machine to the JTF-MW
control card. New JTF-MW control card (part Number 03117541-01) is released and have to order
together with the kit (03155561-01) for QP2 to be retrofitted for all remaining affected machine. Please
refer to TI2017-02Dis01
for the detailed information.
3.4 D1-127453301 Feeder are in an undefined state after restart of the machine & D1-125647402
Unexpected reboot during feeder eSW download
Apply station software 710.01 SP1 Hotfix04 or later version.
3.5 Gantry Humming/Vibration during movement
Apply station software 710.01 SP1 Hotfix04. Follow retrofit instruction strictly.
