Is it possible to change the specification of high voltage output or ripple voltage after completing the product? |
 |
Yes.ｱ20% of output voltage is possible. In case
of increasing ripple voltage, it is very hard on original
design but we can redesign with additional purchase order.
FUTEX has much more experience to modify the original product.
Please do not hesitate to ask FUTEX the modifications you
need.
 |
|
Is it possible to change the unit dimension? If Yes, how big change modification is possible? |
|
Yes, FUTEX can change unit dimension based on
the customerﾕs requirement. There are two types of units which
are rack mount type and stand-alone type but FUTEX can change
design based on the customerﾕs specification as special product.
The specification will be discussed. . There is a limitation
to change the smaller and thinner requirement because we cannot
take enough distance not make a discharge problem.
|
|
What output voltage or current are increasing to? |
|
Basically, FUTEX takes air isolation system
up to 50kV (Both polarity)/250_A. FUTEX can also make the
power supply over 50kV to 150kV however in case of over 50kV
FUTEX has to use SF6 gas as isolation gas in high voltage
tank.
|
|
What is the procedure of confirming the system adjustment between the instrument and power supply? |
|
FUTEX usually tests and adjusts the power supply
using the SEM or FIB. The adjustment detail is shown below.
1 To confirm the response time as generating voltage change
intentionally. (Confirming the oscillation of output voltage
of high voltage power supply and discharge at output)
2 To confirm the noise at output if it is low enough and to
confirm not to give the instrument bad influence. (Frequency
analysis using FFT (Fast Fourier Transfer) analyzer).
3 To make right GND connection between the power supply and
SEM as confirming the noise at SEM side.
|
|
Is it possible to control the output voltage sequentially? |
|
Yes, the software for PC has been provided as
an option. It can control all functions in the unit and also
can show present the output voltage and current on a monitor.
It is useful tool for developing the instrument using the
charged particle beam.
Please see the operation software for detail.
|
|
Is possible to receive the interlock signal from the system? |
|
Yes, basically, the vacuum interlock and the
door (panel) open-close interlock are acceptable. The additional
interlock also acceptable as an option.
|
|
CE or UL approved? |
|
All FUTEXﾕs products currently havenﾕt
been approved yet by CE or UL.
|
|
How long does it take to delivery from order? |
|
About 3 month for the standard specification.
About 6 month for special specification.
|
|
In case of the power supply failures. What service systems are provided? |
|
There is warranty for one year after the inspection
done. Main service system is replacement. The failure unit
back to FUTEX. The replacement unit is sent to the customer
then FUTEX fixes the trouble of the unit. After fixing the
trouble, the fixed unit is sent to the customer then replacement
unit back to FUTEX.
Please see service support for detail.
|
|
The price range? |
|
The prices are not on list because
all products are produce under special specification. So the
price is decided every order. The power supply (FE303XPA)
TFE (Thermals Field Emission) gin price is about \3M as reference.
The prices are flexible by repeat order or mass order. Please
do not hesitate to ask us about price.
|
|
What is air isolation? |
|
FUTEX does not take air isolation in whole area
of high voltage generation. FUTEX takes the solid isolation
as well. The high voltage area is isolated by solid isolation.
Therefore the 80% of the high voltage generation area is isolated
by the air.
Furthermore the air is required dried air.
Please see the concept of FUTEX high voltage isolation.
|
|
How the specifications of the system communications between high voltage and the instrument are made? |
|
Basically the system communication should meet
the FUTEX communication specifications. However FUTEX will
make the new communication based on the customerﾕs specification.
Particularly in case of instrument side man-machine interface
FUTEX can provide the control software for ActiveX.
|
|
What is the best specification of FYTEX high voltage power supply? |
|
5ppm/℃/hour as the voltage stability on the
accelerating voltage 30kV. 30mV as ripple noise.
5ppm/℃/hour as the voltage stability on the accelerating voltage
50kV. 50mV as ripple noise. |
|
Is only the contract from the design to manufacture accepted? |
|
No need to worry about it. There are a lot of
the customers requiring only manufacture and adjustments also
there are a lot of the customers requiring the design and
the trial manufacture only.
|
|
Is it possible to be accepted small number of products or only one product? |
|
Yes, most of the FUTEXﾕs customers
ask for less than 10 products. The special specification is
also acceptable.
|
|
Is it possible to ask not only manufacture but also the adjustment and trial manufacture only? |
|
Yes, you can do it. It is possible to ask from
adjusting one PC board assemble to the unit assemble and adjustment.
Also it is possible to take supporting to create the adjustment
manual and inspection sheet for first product and to make
testing jig.
|
|
Is it possible to ask small number of procuring the parts? |
|
Yes, FUTEX can procure the necessary
parts for only one unit. FUTEX can procure electric parts,
decorated panel for the unit and machined component. FUTEX
can procure almost all necessary parts. In case of order made
parts, FUTEX borrows the data from the customer then being
able to procure that part. Also in case of the parts in inventory
at customer site, FUTEX will try to spend such parts at first.
The feature of FUTEX is that FUTEX can complete the product
in only one voucher which the customer has sent. So that FUTEX
contributes to save cost at customer site because the management
items are getting uniform as using FUTEX ODM system. |
|
Is it possible to ask from development to
manufacture with no specification? |
|
Yes, FUTEX can support to make the specification
with customer. The technical engineers try to hear the information
from the customer then propose the specification the customer
needs.
|
|
Is it possible to support the
situation of discontinuing parts used in the long life product? |
|
Yes, this is the feature of FUTEX. As FUTEX
has global part procurement network, FUTEX can research and
get them. If the part has been discontinued already, FUTEX
can research secondly part or can design the circuit having
same function as original circuit has.
* About propose of redesign. “Renewal design” is just to design
something new using original design. Particularly in case
of the long life product the part on the PC board often has
been discontinued to produce. In that situation FUTEX tries
not only finding the replacement but also redesigning the
new circuit having the same function and capability not to
make to cause the same trouble again. Also FUTEX takes the
latest part to the PC board to make better capability and
downsizing.
|
|
Is it possible to make the chip part and
DIP part combined PC board with no lead solder? |
|
Basically Yes. FUTEX can make the PC board with
combining surface mount and DIP part. However in case of the
customer has specified the part not for lead free and also
required DIP, FUTEX cannot accept it. The reason is that if
to use the part with lead in FUTEX lead free solder container
for DIP, FUTEX lead free container for DIP will be contaminated.
