고성능을 위한 열효율
Amkor’s ExposedPad LQFP/TQFP family of power IC packages significantly increases the thermal efficiency of power constrained standard LQFP and TQFP packages. These packages can increase heat dissipation by as much as 110% over standard LQFP/TQFP packages, thereby expanding the margin of operating parameters.
In addition, the ExposedPad can be connected to ground, thereby reducing loop inductance for high frequency applications. The ExposedPad should be soldered directly to the PCB to realize the thermal and electrical benefits. 3D packaging with the die stack process is also provided in this package for the MCP solution.
- 패키지 크기: 5 x 5 mm ~ 28 x 28 mm
- lead 개수: 32–256
- 다양한 다이 패드 크기 선택
- 더블 다운셋 접지 본드 링 패드
- TQFP 제품 두께: 1.0 mm
- LQFP 제품 두께: 1.4 mm
- 고객맞춤형 리드프레임 설계 가능
- ExposedPad is easily inverted for heat sink attachment
- 로우 프로파일: 최대 두께 1.2 mm
- Electrical – Very low loop inductance with the use of a paddle as a ground path, more pins available for signal and allows for operating frequencies of up to 2.4 GHz
As increased end-application densities and shrinking product sizes demand more from IC packages, ExposedPad LQFP/TQFP packages provide designers with the necessary margin for designing and producing high-performing products.
Applications such as automotive (engine control units, powertrain and infotainment controllers), LCD/flat panel TVs and telecom benefit from this package. High-speed silicon technologies work especially well in ExposedPad LQFP/TQFP packages due to grounding capabilities.
Amkor devices are assembled in optimized package designs with proven, reliable semiconductor materials.
