How AiP/AoP Technology Helps Enable 5G And More


For 5G smartphones and other millimeter wave (mmWave) applications, antenna integration off the board and into the package, simplifies the design challenges endemic to high-frequency devices. These challenges include signal loss, signal integrity, and power supply limitation. Antenna in Package (AiP) and Antenna on Package (AoP) constructions provide the required form, fit and function for high... » read more

Fan-Out Packaging Gets Competitive


Fan-out wafer-level packaging (FOWLP) is a key enabler in the industry shift from transistor scaling to system scaling and integration. The design fans out the chip interconnects through a redistribution layer instead of a substrate. Compared to flip-chip ball grid array (FCBGA) or wire bonds, it creates lower thermal resistance, a slimmer package, and potentially lower costs. Yet, if the h... » read more

The Race To Zero Defects In Auto ICs


Assembly houses are fine-tuning their methodologies and processes for automotive ICs, optimizing everything from inspection and metrology to data management in order to prevent escapes and reduce the number of costly returns. Today, assembly defects account for between 12% and 15% of semiconductor customer returns in the automotive chip market. As component counts in vehicles climb from the ... » read more

Challenges For Achieving Automotive Grade 1/0 Reliability In FCBGA and fcCSP Packages


As the quantity, complexity, and functions of electronic devices in automobiles increase, understanding and characterizing package reliability is of significant concern and importance. The Automotive Electronics Council (AEC) Q-100 specification for Grade 1 and 0 reliability introduces unique challenges as thermal cycling (TC) and high temperature storage (HTS) requirements increase. Additional... » read more

Metal Thermal Interface Material For The Next Generation FCBGA


Thermal interface materials (TIMs) have been widely adopted for improved thermal dissipation in flip chip ball grid array (FCBGA), flip chip lidded ball grid array (FCLGA) and flip chip pin grid array (FCPGA) packaging. As the next generation devices' requirements for power get even higher, enhanced thermal performance at the package level is increasingly important. A typical TIM applies a poly... » read more

Challenges And Approaches To Developing Automotive Grade 1/0 FCBGA Package Capability


Automotive Grade 1 and 0 package requirements, defined by Automotive Electronics Council (AEC) Document AEC-100, require more severe temperature cycling and high temperature storage conditions to meet harsh automotive field requirements, such as a maximum 150°C device operating temperature, 15-year reliability and zero-defect quality level. Moreover, increased integration of device functionali... » read more
