CSP Test Socket for Optical Laser Failure Analysis w/Emission Microscopy*

 

Available with or without filters for UV, infrared and full spectrum applications, Aries’ new optical test socket is ideal for testing an optical sensor type chip and for EMMI testing a standard chip using an infrared head sensor. The optical test socket line can accommodate many different optical window and lens materials, including glass, sapphire, and plastic depending on operational requirements. The standard optical grade window on the 23023 socket uses a high-quality quartz V077 glass with a 98% transmission rate from <260nm in the UV to >2000nm in the infrared.

* Emission Microscopy (EMMI) is a powerful early-stage noninvasive failure analysis technique localizing failures and requiring little sample preparation. Flip-chip devices, difficult to study by other means, are easily studied through the die without decapsulation and often without thinning, making it an efficient optical analysis technique that will detect and localize certain integrated circuit failures. It can be performed from either the front or back sides of devices.
