Mil/Aero Reliability Inspection for Latent Defects
Elk Grove Village, IL — March 2, 2010
Sonoscan has publicly announced Sonoscan Critical Evaluation™ (SCE), a confidential service that acoustically inspects critical electronic components such as hybrids, capacitors and plastic-encapsulated microcircuits used in military and aerospace systems. The service became active in mid-2009.
Acoustic Micro Imaging nondestructively images hidden latent defects such as delaminations, cracks and voids - for example, a delamination on the face of a silicon chip. It also characterizes materials such as encapsulants.
SCE handles individual components, hybrid devices, and printed wiring boards. The purpose of imaging is to locate, identify and analyze internal anomalies that can cause electrical failures in service, such as die attach voids in a hybrid device or singulation cracks in a capacitor.
In some applications, the interest is on purely mechanical features in items such as micro spot welds or multi-layer composite materials.
Two groups work together to provide SCE:
- the SonoLab® applications laboratory personnel; and
- hardware engineering, machine shop, software engineering and other Sonoscan departments that give specific support as needed.
Typically client engineers handle their own parts and load them into a laboratory C-SAM® system in a secure, certified room at the Elk Grove Village SonoLab®. Acoustic imaging, according to the client's requirements, is supervised by Sonoscan specialists who apply their expertise in critical areas such as image interpretation and the use of alternate imaging techniques to achieve the component reliability required by the client.
The various Sonoscan departments can quickly design adapted fixtures to hold parts, or modify programs to provide the optimum imaging for the critical parts.
SCE gives the client company's engineers the control they need over testing and evaluation of their parts as well as the in-house resources to meet the full spectrum of challenges that are part of advanced testing of critical components.
