Generation of Compact Thermal Model of a Ball Grid Array Package based on Experimental Data
نویسندگان
چکیده
This paper presents generation of a compact thermal model of a Ball Grid Array (BGA) based on experimental test results obtained from infrared (IR) camera system. The model is optimized so that the steady state and transient thermal behaviors of the package may be predicted with required accuracy. The optimization algorithm is based on Gauss-Newton and Levenberg-Marquardt methods which are well known as a fast and high performance method of multidimensional optimization using MATLAB.

متن کاملParameterized Physical Compact Thermal Modeling
This paper presents a compact thermal modeling approach, which is fully parameterized according to design geometries and material physical properties. While most compact modeling approaches facilitate thermal characterization of existing package designs, our method is better suited for preliminary exploration of the design space at both the silicon level and the package level. We show that our ...

متن کاملTransition from Plastic Ball Grid Array to High Performance Wire Bondable Tape Ball Grid Array
Mention Tape Ball Grid Array (TBGA) and the first thing comes to mind is the high cost. In fact, most end users rightfully associate TBGA with the less commonly practiced assembly processes such as Tape Automated Bonding (TAB) and expensive gold bump process. This impression of TBGA repels end users and limits TBGA to mostly high end applications and a very narrow spectrum of lead counts. Times...
