The remarkable increase in counterfeit parts (a factor of 4 since 2009) [1] is a huge reliability and security concern in various industries ranging from automotive electronics to sensitive military applications increasing the possibility of premature failure in critical systems [2-5]. Counterfeit parts can also incur a great financial loss to legitimate electronics companies [6]. The issue is even more alarming as the counterfeiters use more sophisticated methods making counterfeit detection a much harder task [7-8]. Therefore, it is reasonable to develop more advanced counterfeit detection methods targeting a more efficient detection of sophisticated counterfeited parts.

As part of continuous process improvement at KEMET, most failure modes caused by the capacitor manufacturing process have been systematically eliminated. Today these capacitor manufacturing-related defects are now at a parts per billion (PPB) level. Pareto analysis of customer complaints indicates that the #1 failure mode is IR failure due to flex cracks.

We found that NPI process of SMT is mostly similar and sometimes overlapping to tooling process. In addition, in most cases the programmer is part of the team working on the NPI process. So, QPlan was extended with NPI Tools as a part of tooling process. This allows the team to carry out the NPI process at offline. And at the end of it, they can create corrected SMT program at zero time.

In the quest for lower ESL devices, having the ESL reduced in the package is only half of the battle; connecting that device to the circuit determines how much of that low ESL appears to the circuit. For this low ESL part type, it would be a shame to take a part of 200 pH and add 2000 pH to its ESL because of via patterns on the PCB.

In 2005 Raytheon Technical Services Company, now Raytheon Information, Intelligence and Services (Raytheon IIS), approached Ensil regarding the repair of their manufactured Radar Control Terminal (RCT) units. The RCT TRS P/N 13563090-2, a key component in the AN/MPQ-64 Sentinel System, consisted of outdated parts which caused minor to major unit failures. Ensil repaired the RCT's at every turn, correcting any component with the parts still in circulation (mother boards, displays, power supplies) to provide the client with the best available technology. These repairs were completed to military standards and kept the RCT effective, allowing for the Sentinel radar to remain operational. However, the supply of outdated parts was eventually no longer available. Ensil offered the best possible solution, utilizing the skills of their knowledgeable engineering staff, they would reverse engineer a new computer to replace the obsolete RCT while maintaining the same form, fit and function.
