Failure Analysis

Collecting and analyzing data to determine why a microelectronic part or device failed is done by all industries we serve at AcousTech. With careful Failure Analysis, manufacturers gain knowledge that’s essential to the development of new electronic products and the improvement of those already on the market.

AcousTech takes failed components collected by our clients and examines them primarily using C-SAM®, X-Ray, or some combination thereof to determine the cause or causes of failure.

Either process – C-SAM® or X-Ray – may be used as the first step in nondestructively identifying a host of potential problems. Both, for instance, are useful in examining the condition of a microelectronic device before it’s desoldered from a board, which can alter its condition. Beyond that, C-SAM® excels in exposing die surface delamination, leadframe delamination, delamination at a wirebond, and cracks. X-Ray inspection is especially good at finding lifted or shorted wire bonds, excessive die-attach voiding, extraneous material, excessive die-attach material, and chipped die edges.

Every type of microelectronic part or device is prone to failure and thus a potential candidate for Failure Analysis. Typically submitted to us are… 

  • PEMs (plastic encapsulated microcircuits) such as SSOPs, SOICs, PLCCs, MSOPs, PQFPs/TQFPs, CDIPs/PDIPs, BGAs/FBGAs, and SOTs,
  • devices on PCBs (printed circuit boards),
  • hybrid devices,
  • flip chips,
  • medical implants, and
  • automotive sensors. 

The C-SAM® standards that apply are…

The standards that apply to X-Ray inspection are… 

Our Failure Analysis services also entail providing you with… 

  • a quick turnaround,
  • a detailed yet concise pass/fail report that notes all defects discovered,
  • a certificate of conformance, and
  • a CD that includes all images taken during the tests and/or the original X-Ray films. 

Beyond that, we offer you the same professional collaboration and competitive pricing that complete the benefits of partnership we extend to every AcousTech client.
