Panther 16K - Ultra fast Harness tester


Overview
  1. Designed as an Ultra Fast Open / Short tester for Flexible Circuit / PCB manufacturer or IC manufacturer, where production testing is involved
  2. High speed testing at 128 seconds for 128 million test combinations
  3. Can be interfaced to any type of test fixtures
  4. Fast turnaround time to test new products.
Features

It can be interfaced to any fixtures as required.
Its fast test time of 1 micro-second per pin combination, is userful, for it helps, to increase test yield and productivity.
It uses the Learn from a Known Good Board and test against target board technique. This reduces the time required to generate, otherwise, tedious test program.
Fast turnaround time to test new products.

Panther 16K is a new generation Open / Short tester applied for Semiconductor Industry with whole new fleet of features that makes the task reliable, complete and fast. It uses Force Current – Measure voltage to test opens, shorts, leaks and diode drops.

It uses an ultra fast programmable current source.
The constant current is programmable from as low as few micro amps to 50 milli amps in three ranges and 13-bit resolution.
The voltage compliance (Voltage Clamp) is also programmable within between -2V and +7V in 13-bit resolution.
The time base is programmable from 1µs per test to 256µs per test in steps of 1µs. Programmable wait states between zero to 255, used to extend the test time if required.
Panther 16K has two comparators with their thresholds fully programmable in 13-bit resolution between -10v to 10V and produces a 2-bit test result code for each test combination.
The user can choose to use one comparator for simple open / short application (2 band, 1 bit test result code), 2 comparators for open / diode / short classification (3 band, 2 bit test result code) classifications.
Panther 16K utilizes full hardware comparison so as to achieve fastest time for test.
It can accept open / short data entered by operator or a net-list down load or can Learn from a known Golden Device.
By utilizing hardware compare the Go – NoGo test time is just the hardware drive time and it is the fastest.
For a full failure analysis (FA) it can give the complete failure information for up to 128 Mega test combinations from its acquisition RAM.
It also has the facility to store the first 8192 failures for an optimum Test and FA information retrieval Time.
Panther 16K uses 4-wire measurement using fast analog switches for accurate voltage measurements and improves accuracy.
Each Mux card holds 256 channels with 4-wire measurement capability.


Multiple Test Techniques:

Mode 1: Serial Shift Method
In this mode, one pin at a time is connected to a current source and all other pins are connected to GND.

Mode 2: Fixed Reference Method
In this mode, any pin can be made as fixed reference pin and all other pins are tested.

Mode 3: Half QSM Method - n*(n-1)/2 combinations
In this mode, all combinations of pins are tested as pair by pair excluding reverse combinations. Same pin as reference pin and test pin combination is skipped.

Host PC and Software Features:
Panther 16K is interfaced to a Host PC through 32bit PCI interface card. The operating system is Windows2000 or XP.
