TBGA/CLTBGA
Tape Ball Grid Array/Closed-Loop Tape Ball Grid Array

Developed and patented in 1995, ASAT’s TBGA and Closed-Loop TBGA packages provide the industry with a higher performance solution to the QFP. ASAT’s TBGA package is an excellent choice for applications requiring enhanced thermal and electrical performance. ASAT’s CLTBGA option provides solid ground for improved signal-to-noise ration and reduced ground inductance. The ultra-fine metal line width and spacing allows most designs to be routed on one metal layer. A two-metal option provides multiple power supply rings and improved routability for high ball count applications, typically above 600.
