 The
Sonix™ applications lab is a full service contract lab that provides
acoustic microscopy and ultrasonic inspection services. The lab serves a
variety of industries including microelectronics, aerospace, automotive,
composite and biomedical. The contract lab performs a variety of short-term
and long-term inspection services to evaluate your packages and parts and
provide you with detailed applications reports.
The lab employs both state of the art equipment and highly
skilled applications engineers trained to use advanced diagnostic
techniques. Detailed reports are generated for each application and display
ultrasonic images, identify failure modes, internal bond characteristics and
internal defects.
The contract lab’s acoustic microscopy services include
failure analysis, new package qualification, production sampling and more.
The lab diagnosis a variety of packages including plastic and ceramic
packages, hybrids and MCMs, Flip Chips and CSPs, capacitors and BGAs.
The lab’s ultrasonic inspection services include a variety
of material analysis including volumetric analysis of voids, defects and in-homogeneity,
as well as thickness, density, velocity, mapping and acoustic impedance
measurements.
Let the Sonix™ applications lab team evaluate your packages
and parts and provide you with detailed application reports that diagnose
your problems.
Sonix™ has recently been awarded a patent for simultaneously
generating Pulse-Echo (PE) and Thru-Transmission (TT) images (US Patent
#6,032,534).
Simultaneous Pulse-Echo and Thru-Transmission
(PETT)
generates two images in one scan. Using PETT, both a Thru-Transmission image
and a Pulse-Echo image are generated simultaneously saving the user time and
providing quick defect detection and verification in one scan. In addition,
pulse-echo scans can be generated from each side of the device in just one
pass.
PETT offers these advantages:
PETT turns a two-step process into one quick and easy scan.
The user can quickly look at the Thru-Transmission image to determine if a
defect is present. If a defect is present the user can then look at the
Pulse-Echo image showing the physical characteristics of the defect such as
where it is located.
Sending the acoustic signal the whole way through the part
where a receiving transducer collects the signal generates the
Thru-Transmission image. The generated image quickly shows whether or not a
defect is present.
The Pulse-Echo image is generated by reflection. In
pulse-echo, the signal is sent through the part and signals at different
depths are reflected back. The image generated by pulse-echo provides the
details of the defect, such as what interface the defect occurs.
PETT is an extremely powerful tool that reduces scan time
and is easy to setup. It provides the user with tools for quick defect
detection.
