The instructor shares his years of experience related root cause FA investigations of microcircuit packaging defects and failures. Mismatched CTEs and poorly designed packages geometries often lead to mechanical failure at the die and substrate interface or cracking at the heel of a wire or ribbon bond interconnect. Careful delid, visual inspection followed by SEM and EDAX/Auger are required to identify root cause. Reliability engineers must be cognizant of the full range of FA tools available to diagnose failures and, resist the temptation to rush to judgment, which often happens destroying valuable evidence along the way. The instructor will review real world specific examples of packaging failures and resultant FA analysis and problem resolution. This course is intended for reliability engineers, design, quality and process engineers involved in microelectronic packaging.View full course outline.
Hermeticity of electronics packages including hybrids, microwave modules, MEMS, Class III medical implants, continues to be of critical importance. This course begins with an overview of hermetic sealing processes and then examines the accepted leak test techniques as prescribed in MIL-STD-883 Test Method 1014. Issues with bomb times and pressures, measured leak rate vs. air leak rates, "one way leakers," and virtual leakers will be addressed, along with gross leak testing. In each case the focus will be on practical issues facing the industry. The basic science and applicability of both Optical Leak Test (OLT) and Cumulative Helium Leak Detection (CHLD) will be described with plenty of time for questions. The gas ambient inside the package is measured using Residual Gas Analysis. What is RGA (Residual Gas Analysis)? How does it relate to hermeticity testing? Packages made from polymeric materials as opposed to traditional hermetic seals (i.e., metal, ceramic, etc.) require a different approach from a testing standpoint. The problem is now one of moisture diffusion through the barrier and package interfaces. A brief review of the techniques and methods to evaluate a "non-hermetic" approach is presented.
This course is intended as an introductory to intermediate level course for process engineers, designers, quality engineers, and managers responsible for seal, leak testing, and RGA results, and for those responsible for evaluating new cavity style packages.View full course outline.
Reliable packaging of MEMS requires the ability to create and maintain a suitable inert atmosphere or vacuum inside the package cavity for the expected lifetime of the device. Traditional hermetic ceramic/metal packages are being replaced by wafer level packaging techniques, which present unique challenges from a hermeticity testing perspective. This course begins with an overview of traditional hermetic sealing processes along with wafer level MEMS packaging processes and methods. In some cases near-hermetic packages, such as LCP are suitable in some applications. Testing of small cavity MEMS packages according to the traditional Mil Spec TM 1014 requirements may not be sufficient to guarantee reliable operation. Difficulties and limitations in fine leak testing of small volume packages will be addressed. Recent advances in Optical Leak Testing (OLT), Cumulative Helium Leak Detection (CHLD) and Radioisotope KR 85 along with other hermeticity techniques are reviewed in light of the new, tighter leak rate hermeticity specifications. Moisture ingress is of primary concern for a small volume MEMS cavity packages. Moisture level vs. surface area to volume ratio is an important concept, along with material outgassing and the potential to mitigate these problems with getters. These along with other critical MEMS packaging issues are addressed in this course.
This PDC is intended as an introductory level course for process engineers, designers, quality engineers, and managers responsible for packaging and hermetic testing of cavity style MEMS.View full course outline.

Hermetic and non-hermetic packaging and testing of microelectronics, sensors, MEMS, hybrids and microwave components for use as implanted Class II/III devices in vivo is of critical importance. Cost, reliability, small form factors, biocompatibility and patient safety are driving concerns. This course begins with an overview of traditional hermetic packaging and testing approaches that have been in use for over forty years. Most pacemakers, IPGs, cochlear implants in use today follow a prescribed and proven path of hermetic sealing and testing to assure product reliability and patient safety, which includes hermeticity testing in accordance with MIL-STD-883 Test Method 1014. Today however, the research is directed at development of a non-hermetic package that is at least as good as the proven path. Packages made from polymeric materials require a different approach from a manufacturing and testing standpoint. The problem is now one of moisture diffusion through the barrier and package interfaces. Candidate materials such as parylene, PDMS, various ALD and CVD organic and inorganic coatings, LCP, silicones etc. are reviewed and application processes discussed. How to test and evaluate "non-hermetic" packaging methods is a primary learning objective along with an understanding of the risks and consequences of failure.
This course is intended for process engineers, designers, quality engineers, and managers responsible for package seal, hermeticity testing and for those responsible for evaluating non-hermetic packages for medical implants.View full course outline.
