3. Never attempt to put a part of your body in the working area of the product. Otherwise it may
possibly cause a serious accident.
4. While using the product, be sure to close the safe cover of the tester. Otherwise it may possibly
cause an electric shock or other bodily accident.
5. Once some smoke or bad smell came from the product, it may possibly cause a burning or electric
shock and is very dangerous. In such case happened, switch the power off and stop operating the
product on the spot, then consult to our local distributor for the solution. Do not use the product
until safe operation can be verified by service-trained personnel.
6. Once some liquid or foreign material was put in the product, it may possibly cause a burning or
electric shock and is very dangerous. In such case happened, unplug the product and stop your
operation on the spot, then consult to our local distributor for the solution. Do not use the product
until safe operation can be verified by service-trained personnel.
7. Once you felt something strange during the operation (i.e. noise, smell, malfunction, etc.), switch
the power off, unplug the product and stop your operation on the spot, then consult to our local
distributor for the solution. Do not use the product until safe operation can be verified by
service-trained personnel.
8. The product power must be OFF and unplugged when the product is serviced for maintenance or
cleaning. Needless to say, the service must be made by service trained personnel only who are
familiar with electronic circuitry and understand the hazard involved.
9. The product power must be OFF and unplugged before replacing or maintenance any part of this
option.
10. The manufacturer has no responsibility for such defect resulting from misuse or unauthorized
modification by user, as well as operation outside of the environmental specifications for the
product.

§1 General
This section provides fundamental information on the IC Open Test system CS-9500.
Outline
With this optional system built-in, the Takaya PT-9411CE Series (hereafter “Tester”) enables to detect
unsoldered IC leads of QFP, SOJ, so on while contacting the independently moving sensor probes on
the IC’s package. unique spring-embedded sensor probe (hereafter “Sensor probe”) contacts the IC
leads directly in place of the probe, so that the test is unlikely to be falsely judged due to possible
contact error. In addition, the test program is easily and automatically created in a very short period of
time.
CS-9500 Hardware
(1) IC Open measuring PCB (T K Y TVX-11)
(2) ntenna drive unit and Sensor probe (Each one at Left/Right)
Hardware location
The hardware is installed in the tester as shown in Fig.1 below.
[Fig.1] Tester appearance
Measuring principle
The measurement principle is outlined below.
[Fig.2] Measuring principle
s Fig.2 introduce, the sensor probe is supposed to contact directly on the IC package under test
while impressing C measurement signal between an individual IC’s lead and the GND point on the
PC board. This sensor probe consists of a special antenna that can receive a signal radiated from the
lead frame inside the IC through its mold package. If some IC’s leads were improperly soldered
otherwise open, the signal level becomes small so that their failure can be detected accordingly.

Antenna drive unit & Sensor probe installation
The antenna drive unit that includes the sensor probe is installed on the Z2 axis and the Z3 axis.
Contact position of Sensor probe and probe
s shown in Fig.3 below, the sensor probe which is equipped with a round sensor plate (diameter
φ5mm) on the top steps on IC package where is nearby each IC lead to be measured. So their
stepping position shifts sequentially according to the testing order.
[Fig.3] Sensor probe’s contact position
Meanwhile, the contact position for the probes which impress the necessary measurement signal
should be properly selected depends on the IC solder pad.
Large solder pad
When there is enough space on the IC solder pad and a few possibilities that any probe may
interfere with the IC lead, it should contact on the IC solder pad directly.
S all solder pad
When there is less space on the IC solder pad, in other words there is a risk for the probe to
interfere with the IC lead, otherwise when the objective IC is PLCC-type which has no IC solder pad,
the probe should contact any other point where is connected with the objective IC solder pad on the
same circuit pattern.
[Fig.4] Probe’s contact position
In addition, two GND points where to contact by another probe should be available on the left-hands
and the right-hand corners on your PC board. If the GND point was set incorrectly, some of IC open
test steps would not be created. (In this case, the VF measurement steps is created instead)
Reference Value for PASS/FAIL Judgment
The reference value for the IC open test is also learned from a good sample PC boards automatically
as usually done to program the component steps.

Progra ing IC Open Steps
The tester allows easy programming of IC Open test as well. The user can use a CCD camera to
directly input the XY coordinates where the sensor probe contacts or outsource the creation of test
program to C D data converters. Inputting the XY coordinates of all four corners on the IC package as
well as the number of the IC leads, the tester can automatically create the XY coordinates for the
sensor probes to contact.
Measura le ICs and conditions
1. IC outward dimension is over 6mm each side (QFP, SOP, PLCC, LCC, MSP, so on)
2. IC mold thickness is less than 2.5mm from the lead frame. (It depends on the material and the
frame area)
3. The probe is more than 2.8mm away from the sensor probe
[Fig.5]
Unmeasura le ICs and conditions
1. Unmeasurable ICs
• SIP and such ICs that has no or a very small lead frame inside the IC’s package
• ICs which mold thickness is more than 2.5mm from the lead frame
• ICs in which shield plate or heat sink is installed over the lead frame
2. Unmeasurable conditions
• GND line and Vcc line
• IC’s lead with very low impedance of less than 20 ohm (equivalent to approx. 0.9µF or more in
Capacitance) against GND line or Vcc line.
[Fig.6] Unmeasurable ICs and conditions
The IC open test of two adjacent IC leads on the same line is possible only when they
got fail at the same time.
ny breaking of the lead wire inside the ICs, any miss-orientation, or any miss-mount
cannot be detected.
There may be other cases that are unmeasurable due to the wiring (and mounting)
condition on the boards or type of the ICs being tested.

Test speed
The test speed depends largely on travel distance of the test probes and the IC lead pitches. Let’s say
for instance that we test a QFP with 0.65mm pitch while directly contacting the IC lead pads. In this
case, we can estimate max. 0.10 - 0.15 sec./point approximately.
