Wednesday, March 13, 2019 | 05:30PM
Location: PSemi, 9369 Carroll Park Dr San Diego, CA 92121

fcLGA Package Assembly Qualification for Mobile Applications
Presented by
 Mumtaz Bora Sr. Staff Packaging Engineer at pSemi Corporation
Flip Chip Land Grid Array (fcLGA) packages are widely used in Mobile product applications due to their thin form factor and performance. Assembly process qualification requires careful selection of materials and optimization of reflow processes to make consistent and reliable product. The fcLGA typically uses an organic substrate on which the die is reflowed instead of the copper lead frame used in QFN packages. This requires assessment of CTE mismatch and controlled reflow processes to prevent bump separation .The paper reviews the selection of substrate, optimization of assembly process and reliability testing conducted for fcLGA package qualification. 
Speaker: Mumtaz Y. Bora has a B.S. in Chemistry and Material Sciences from University of Mumbai, India and University of Ottawa, Canada. She has a Master of Science in Interactive Telecommunications from University of Redlands, California. She has over 25 years of PWB, SMT assembly and advanced packaging development experience at IBM Endicott and IBM Austin, TX.  She has worked in new product development, and qualification of high volume handset assemblies at Qualcomm and Kyocera-Wireless Corporation.  She has worked with suppliers and subcontractors in several parts of Asia.  She is currently a Sr. Staff Packaging Engineer at pSemi for qualification of RFIC packages for wireless, broadband Automotive and Power applications. She is a member of IPC standardization committees and contributes to the standards development. She has 18 publications and 3 patents. She is the Past President of the SMTA San Diego chapter and Co-chair of the Moisture Sensitive Devices Council. She is currently the Publicity Chair for  IMAPS San Diego Chapter and Vice President of Communications at SMTA San Diego chapter.
