The 5300 provides most of the equipment necessary to perform
Flash Testing on capacitors/ one part at a time. The total
test time can be less than 30 milliseconds/ allowing for
rapid flash testing in a production environment.
The' 5300 is designed to be easy to use/ yet versatile. All
test conditions are set through the use of six front-panel
pushbuttons/ aided by a 20-character display/ or through a
remote device connected to a communication interface.
The 20-character display is a vacuum-fluorescent display#
located on the front of the 5300. It provides the primary
method for indicating operating conditions/ test results/
and system errors to the user.
There are three front panel modes: Enable/ Set/ and
Configure. The Enable mode is the only front panel mode in
which a Flash Test may be performed. While in the Enable
mode/ test conditions may be displayed but they cannot be
changed through the front panel controls. The Set mode
allows the test conditions to be changed through the front
panel controls as well as displayed. The Configure mode
allows the rarely-changed system parameters to be viewed and
Access to the different front panel modes is controlled
through the use of the access keyswitch on the front panel.
The Set and Configure modes are disabled while the keyswitch
is in the ENABLE position. This allows for protection
against accidental changes to test conditions during normal
Several printouts are available to provide a hard-copy
output of test conditions/ detailed bin count totals/ or
system configuration. This information can be output through
the optional (Centronics-compatible) Parallel Printer
Interface or through any of the optional communication
In addition to the 20-character display/ there are thirteen
LEDs on the front panel that inform the user of the test
results and the current operating status of the instrument.
The 5300 contains non-volatile memory, permitting all test
conditions and communication parameters to be permanently
stored until changed. This eliminates the need to reprogram
the instrument every time it is powered up.
Calibration of the 5300 has been designed with convenience
and safety in mind. The calibration values are changed
through the use of the front-panel pushbuttons. Access holes
are provided in the rear panel for the calibrations that
require monitoring of internal conditions. The complete
calibration procedure is accomplished without removing any
of the cabinet covers or performing any mechanical adjustments.
Communication interfaces are available as options to allow
the 5300 to communicate with a component handler or computer
(using RS-232-C/ RS-449/422, or GPIB). These interfaces
allow a remote device to start a test/ monitor the status of
the test/ and receive the results of the test. In addition/
these interfaces allow test parameters to be read and changed.
Connection to the component handler is accomplished through
the Test cable assembly. This cable assembly provides a
pathway for two essential sets of signals: the test signals
and the interlock signals. The test signals are found on two
lines: HV Output/ which carries the current applied to the
DUT; and Sense Input which carries the current returned
through the DUT. The interlock signals are used to monitor
the status of two switches on the protective cover at the
test head. The Test cable assembly also carries various
logic signals that allow a test fixture to initiate a test
and receive the results of a test. The Test cable assembly
connects to the test connector that can be mounted either on
the front or on the rear of the instrument.
The process of flash testing capacitors with the 5300 begins
with powering up the instrument and setting the test
conditions- The test conditions are viewed and set on the
20~character display through the use of the six front-panel
pushbuttons and the access keyswitch or through the use of
the communication interfaces.
Once the test conditions have been properly set (and the
access keyswitch is in the ENABLE position}/ a capacitor is
placed in the handler and is contacted by the test head
probes. The 5300 is instructed to begin testing through one
of the communication interfaces/ through the Handler
Interface, or through the Test cable assembly. The 5300
responds to the request by indicating (on the front panel/
through the active communication interface/ and through the
Handler Interface) that it is testing and begins the Flash Test.
When the test is complete/ the 5300 signals that testing is
complete and displays the result on the front panel/ through
the communication interfaces that have requested results/
and through the Handler Interface (if the handler initiated
the test). The capacitor should be removed and processed
according to the test results and another part should be put
in its place.
