What Role Does Advantech’s PCIE-1840 High-Speed Digitizer Play? - Alltronix India

As technologies are progressing and the world is
advancing, electronic components are becoming
larger and intricate. And, these large and
intricate components require more intricate
PCBs. This has brought innovations in the
development of high density wiring and
advancement in drilling technology. One of the
most important processes of this innovative lot
is the no-contact laser process that requires no
blades for manufacturing high density PCBs. This
technology rules out problems of blade blunting
and chipping, while also bringing better
performance on hole diameter accuracy, quality
consistency, and process speed.
But, in this laser technology, where multiple
laser pulses are required to be shot every
minute, the pulses must maintain a consistent
waveform so that the laser beam can make neat
holes of the same shape and size. To clearly
identify any variations in the waveform, IPC
controlled devices are paired with a monitored
laser pulse waveform measurement system to
ensure drilling quality. There are many
manufacturers who can offer equipment for such
PCB precise drilling and milling. There must be
high standards met for the product quality, high
precision, high efficiency, high stability, and
low operation costs so that the products can be
taken to the next level. For this, digitizers
must be of 14-bit resolution, and use CO2 laser
drill. It must be able to collect pulse signals
with high speed, and perform specialized
computing like data accumulation and comparison
with preset values. Advantechs laser pulse
signal measurement includes PCIE-1840 high-speed
digitizer for precise laser pulse signal
collection, a customized FPGA for performing
specialized computing, and a customized Windows
driver for simple development. First, the laser
2
pulse signal acquisition stop point and standard
and error values are set via the customized
Windows driver. Then, the PCIE-1840 installed in
the IPC automatically captures pulse signals,
after which the collected data is accumulated on
the FPGA that is embedded in the PCIE-1840.
Then, the sum is compared with the preset
standard and error values. The results attained
are then transmitted to the IPC. The results, if
within the preset values, are stored in the IPC
hard disk for future tracking and searching. If
not, a variation in the laser pulse is implied,
based on which the IPC may either send out a
warning or perform a shutdown. The 4 channel
PCIE-1840 here increases the precision of laser
drills by four times, while also enabling high
speed continuous data acquisition. Thus, the
PCIE-1840 is a quality product with super high
performance available at a comparatively
reasonable cost. Thus, we can see how this new
digitizer is an indispensable pulse signal
acquisition tool for laser drill pulse
measurement system development. The digitizers
resolution and sampling rate determine if the
high speed and precise data acquisition
requirements of the equipment are satisfied.
Advantechs PCIE-1840 is the worlds first 4
channel digitizer that is extremely suitable for
applications requiring high speed pulse signal
collection. Alltronix is an Advantech distributor
