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

CSP Test Socket
CSP Test Socket for Optical Laser Failure Analysis

Available with or without filters for UV, infrared and full spectrum applications, this 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 24014 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.

FEATURES

  • Aries unique universal socketing system allows the socket to be easily configured for any package, on any pitch (or multiple pitch) from 0.2mm or greater, in any configuration, with little or no tooling charge or extra lead-time.
  • For Test & Burn-In of CSP, µBGA, Bump-Array, QFN, QFP, MLF, DFN, SSOP, TSSOP, TSOP, SOP, SOIC, LGA, LCC, PLCC, TO and any SMT package style made. Also can be compatible with PGA packaged devices.
  • Quick and Easy Probe Replacement System: the complete set of probes can be removed and a new set (interposer) can be inserted quickly and easily. The old set can be returned to the factory for repair and sent back within one day.
  • Socket lid nests device into socket for a reliable connection.
  • ZIF style socket using Aries solderless, Au-plated pressure mount Spring-Probe.
  • Special lid designs and/or materials can be quoted.
  • Socket easily located, mounted & removed from PCB.
  • Signal path during test only 0.077 [1.96].
  • Available with Spring-Probes or Kapton Elastomer Interposer.
  • 4-point crown insures “scrub” on solder oxides. Consult factory for other available probe styles.
  • The Au over Ni-plated compression Spring-Probes leave very small witness marks on the bottom surface of the device solder balls.

Ordering Information

A detailed device drawing must be sent to Aries to quote and design a socket.
