JET-300 is an automatic test
equipment which measures the impedance of all electronic components
on a loaded printed circuit board. Components such as resistors,
capacitors, inductors, diodes, transistors, FET, SCR, LED,
ICs, etc. are all the objects for this tester to detect. The
opens/ shorts fail, incorrect and disoriented components could
be located. The overwhelming functions do help the users to
find the faults and improve the quality efficiently.
In addition, JET-300 ICT has
superior software system supporting for program preparation
before testing. The system is also powerful in locating the
faulty component and producing the statistic reports of test
data from testing results easily. The hardware facilities
equipped with lots of advanced technologies such as reed relay
scanner board and Agilent TestJet Technology etc. JET-300
ICT always aims at being the greatest partner in your production
lines!
”@Below are the special features of
JET-300”@
REED
RELAY SCANNER BOARD
JET-300”¦ scanner board uses reed
relay, which is able to stand 200 million-time testing. Equipped
with reed relay scanner board, JET-300 has greatly different
functions from ICT that uses CMOS relay scanner board.
- Zener diode testing voltage could be reached up to 50V
for all test points.
- The measurement of small capacitors and small inductors
are more accurate and stable. They are not so influenced
by temperature.
- The Reed Relay scanner board's detecting ratio to polarity
for electrolyzed capacitor is much higher than the scanner
board, which CMOS employed.
- Reed relay can stand higher voltage. In addition, the
detecting function to the residual voltage is designed to
protect scanner board from damage.
- Due to the high voltage durability feature of reed relay,
it allows others optional testing device to add in.
Agilent TestJet Technology
Agilent
TestJet Technology is developed by Agilent company. The technology
is used to detect the solder open of SMD IC's pin. JET-300
is authorized by Agilent to use this technology, thus the
testability is improved and satisfying test result can be
obtained on digital type PC boards such as computer mother
boards, interface boards, fax cards and CD ROM boards etc.
- It measures the capacitor between the copper foil and
the frame of IC to detect if it is open in SMD IC pin. The
users do not have to write any program and it could test
and report correctly and efficiently.
- It can test any type of IC such as Insertion type, PLCC
type, QFP type, TAB type, PGA type, BGA type (OMPAC) etc.
- It can detect the open fail of any kind of socket, such
as insertion type and SMD type
Wide frequency and accurate phase measurement
The component value could be measured
individually when RC or RL are paralleled. Because of the
wider signal resources frequency (in between 100Hz to 1MHz),
the tester can detect more than other ICTs, the component
in the circuits below could be measured correctly.

Transistor 3-terminal mode test &
4-terminal mode test
3-terminal
component such as Transistor, Digital Transistor, FET, SCR
etc. 4-terminal component such as Photo Coupler could be correctly
measured. The wrong insertion or defective part could be detected
definitely. The £] value of a transistor could be measured
.
Polarity check for aluminum
electrolyzed capacity
The coverage could be 100% when
using 3-terminal measurement to detect the polarity of aluminum
electrolyzed capacitor; the coverage could be very high when
using leakage current measurement to detect the polarity of
electrolyzed capacitor.
”@SOFTWARE SYSTEM”@
The software to JET-300
system is more transcendental than any other ICTs”¦ The menu-driven
operation system under windows is not only easy to use but
also very powerful in programming and test data analysis.
Rank of top 10 fail components
The top 10 fail components and
the top 10 fail soldering points messages will be produced
as a clear rank for manufacturers to do quality control or
process improvement.
Daily/Monthly reports
The upper half of display is a
bargraph showing the test yield, open fail, short fail and
component fail percentage of every day in the current month.
The lower half of picture is a pie chart showing test yield
information of the current day.
Real time monitor system
When putting several ICTs on network,
the managers can get the testing statistics information from
any workstation on network.
The inquiry system for
error message.
If ICTs and troubleshooters stations
are on the network system, the error message could be shown
on any troubleshooter station, including the error message
printout and graphic display.
Board view function
When it happens to fail in testing,
the location of the failing component or the failing soldering
point can be displayed on the screen graphically. Besides,
the location of any component could be shown on the screen
graphically by using inquiry command. These functions greatly
shorten the time to repair a bad board and the time to debug
the test program. If network system is built in the facilities,
the error message as well as the graphic display can be shown
on the troubleshooter stations.
