Credence Unveils New High Density V/I Instrument for the Diamond Test Platform

Credence Systems Corporation (NASDAQ: CMOS), a provider of
automated test equipment (ATE) solutions for the worldwide
semiconductor industry, unveiled the latest addition to its family
of value-driven instruments for the Diamond test platform. The
72-channel HDVI (High Density Voltage/Current) instrument is
targeted at significantly reducing the cost of test by enabling
large numbers of sites to be tested in parallel. The HDVI
instrument's high-precision source and measurement capability is
ideal for testing microcontrollers, audio, video, wireless
cellular, digital camera, baseband and power management devices
used in a broad range of cost-sensitive applications.
The industry-leading V/I channel count of the HDVI -- up to 432
channels on the Diamond 10, and 1728 channels on the Diamond 40 --
results in significantly lower cost-per-channel. It also helps to
free up more instrument slots in the tester, thereby enabling
larger multisite configurations. When combined with the Diamond
platform's other high-density instruments, HDVI increases the
capacity of each test system and consequently reduces the number of
test cells needed on the production floor. At the same time,
throughput is dramatically increased by the high degree of parallel
test capability.
"Our customers continue to face intense price pressures, which
is driving higher-count multisite testing for cost of test and
throughput improvements. SoC/SiP devices are also growing more
complex through increasing integration of features, placing greater
pin-count and test coverage demands on ATE," stated Amir Aghdaei,
senior vice president of field operations and marketing at
Credence. "Clearly, acquisition costs and operational efficiency of
the test system have become especially critical. With the addition
of the HDVI instrument, the Diamond platform can cost-effectively
test higher site counts without additional capex demand, helping
our customers to stay on top of rising demand and falling ASPs and
thus meet profitability goals."
Diamond HDVI Instrument: Technology Summary
The HDVI instrument enables efficient use of test head resources
(slots) via a broad range of functionality and innovative features
that traditionally required multiple V/I options on other
platforms. The HDVI contains 72 channels that can be operated in
one of two modes: (1) Voltage/Current Supply (VIS) and (2)
Precision Analog Source (PAS). The VIS mode offers 72 channels of
general purpose, four-quadrant V/I capability for up to +/-7V and a
maximum of +/-2A. In the PAS mode, each channel is capable of
sourcing user-defined analog waveforms with very high accuracy for
driving analog inputs of microcontrollers and embedded ADCs to
perform INL and DNL tests.
Key HDVI features and benefits:
-- Industry-leading V/I channel density delivers best throughput and
parallel test efficiency.
-- Built-in, high-bandwidth input matrix allows external instruments to
connect to multi-use DUT pins and eliminate loadboard components.
-- Trigger control for source and measure memory synchronizes operation
with tester or DUT events.
-- High-current performance on large number of pins provides coverage for
the growing embedded power management features in battery-driven consumer
products.
-- High-accuracy voltage ( < +/-0.9 mV) and current ( < +/-80 nA)
measurements enable reliable testing of sensitive reference pins.
