LED die package factors of higher current density, color uniformity and process residues require an understanding of both assembly and materials to improve reliability of chip on board and flip chip structures. A single LED failure results in a luminaire fail. Residues present on LEDs subjected to high temperature and humidity can impact color intensity, corrosion, poor interfacial bond strengths, insufficient wetting of underfill, leakage currents, electrical noise and field failures.
Cleaning process residues has been reported to improve wire bonding quality, reduce color shifts and prevent electrochemical migration. The test board for this study has sensors placed under and at the peripheral of the die package. The DOE will test leakage currents on both cleaned and uncleaned devices. Inferences from the data findings, conclusions and process recommendations will be reported.
Dr. Mike Bixenman (aka Dr. Mike) is known to many as the world's leading expert in cleaning electronic circuit assemblies and advanced packages. He is also one of the industry's leading authorities on the design of electronic assembly, cleaning materials and process integration. In fact, Dr. Mike literally wrote the book on electronics manufacturing process cleaning standards (Cleaning & Contamination Process Guide).
A much sought-after presenter and global speaker, "Dr. Mike" has been featured on the cover of SMT Magazine and has published hundreds of industry white papers and cleaning hand books that are used around the world as today's leading applications references.
Despite all of Dr. Mike's hard-to-achieve industry recognition and demand, he is always approachable and ready to help engineers and technicians who need to improve their cleaning processes.
Dr. Mike' contributions to the electronic assembly industry have lead to multiple professional honors and recognitions, including the IPC President's Award and chairmanship of the IPC/SMTA Cleaning Symposium. Currently, he is chair of the IPC Cleaning Handbook Task Group. In addition to a Doctorate in Business Administration, Dr. Bixenman holds three other earned degrees.
