“The quick work your team did...was key to getting the customer confidence back."

Just wanted to say thank you again. The quick work your team did on uncovering the capacitor cracking was key to getting the customer confidence back. We were heading off on a different path, but with your help, we found that our plant was not sawing the quad array of PCB panels apart. This was the issue on that small lot of parts and explained why they had the rejects. Pilot run lots were sawn before and have been since without any failures of the cap in question. Thanks again!

“The positive experience with Drs. Hillman and Blattau..."

Over the last six months, DfR Solutions, specifically Drs. Craig Hillman and Nathan Blattau, has been actively working with me and other solder experts as part of an Independent Review Team (IRT) to determine the root cause and corrective action for a solder joint failure on a space vehicle electronics box. The IRT effort required reviewing, analyzing, and drawing conclusions from a variety of detailed visual and x-ray inspections. It also required detailed Finite Element Analysis (FEA) of the various solder joints in the electronics assembly. Dr. Hillman excelled in using his detailed knowledge of electronics assemblies and solder joints to help focus the team and drive to conclusions and recommendations. Dr. Blattau’s FEA expertise was instrumental in converging the analysis efforts of various teams through his knowledge of fatigue damage and the modeling of the creep behavior of solder. It is because of the positive experience with Drs. Hillman and Blattau that I can enthusiastically recommend DfR Solutions to others with similar needs.

“Professional excellence..."

DfR Solutions has recently consulted for us on critical quality/reliability cases. We are very glad to have invited DfR in working on root cause failure analysis, process assessment and auditing, device test methodologies, etc. Their work not only greatly improved our product integrity, but also raised our skills ranging from materials control, failure analysis, to reliability process and methodologies. They truly bring in the professional excellence!

— Geoffrey Leu, Opto Division GM, Unity Opto Technology Co., Ltd.

“The DfR team was highly professional..."

DfR Solutions provided a design review of our high value measurement system and recommended many ways to improve reliability through design modifications, component changes, improved specifications, and test plans. We were very pleased with the results of their analysis. The DfR team was highly professional and we will continue to use their services again and again.

— Kent Kalar, CEO, SensorTran, Inc.

“Reliability expertise...”

Through several times of cooperation with DfR, we have been very happy to identify the failures and solve the problems more easily and more quickly. Besides the excellent accomplishment of projects, our engineers know more about reliability expertise. I am really satisfied with the professional and just-in-time help from DfR.

“DfR has become a champion for our product...”

Nihon Superior has had great success with its patented lead-free SnCuNiGe solder “SN100C,” first in Japan, then in Asia, and we continued that success in Europe. In America the unique features of SN100C attracted a high level of interest as the electronics industry found itself facing the challenge of going lead-free. We realized, however, that to turn that interest into business we would need help in addressing special requirements of the American market. We realized DfR had the skill set that could generate the data we needed. DfR drew up a test program to characterize the performance of alloy and provide the input to a life model that potential customers can use as a basis for designing their assemblies around solder joints made with SN100C. We have been pleasantly surprised to find that the relationship with DfR goes beyond that of just a test house. Without compromising their scientific integrity, DfR has become a champion for our product, looking for opportunities that they encounter in their wide-ranging interactions with the global electronics industry.

“Everyone at DfR Solutions has been a pleasure to work with...”

DfR Solutions has been a primary resource for Failure Analysis investigations on our most critical field failures. They have a staff of highly talented engineers that facilitate a wide spectrum of expertise and analytical skills. We have utilized DfR Solutions for Failure Analysis on various components such as capacitors, power regulators, MOSFETs, and have used their expertise in analyzing PCB fabrication and design issues. They have provided us with FA reports that include detailed results of inspection, chemical analysis, electrical tests, fault simulation, root cause findings, as well as recommendations for remediation and corrective action. Everyone at DfR Solutions has been a pleasure to work with and their ability to be responsive and flexible contributes to making them a great partner in solving problems and improving product quality.

“Further insight and education is also provided...”

I am truly satisfied with the Failure Analysis Investigation of DfR Solutions. In addition to identification of root cause for failure and failure mode of electronic devices/components, further insight and education is also provided regarding the type of failure! The staff are always available, well versed, and extremely professional.
