Qhov kev khiav hauj lwm kub ntau rau LED tsav chips yog -40℃rau +105 degree, thaum cov khoom lag luam qib tuaj yeem txhawb nqa -40℃rau +125℃. Cov kab tshwj xeeb nyob ntawm tus qauv chip thiab datasheet.
1. Cov Cuab Yeej Ntau Yam: Cov neeg siv khoom zoo ib yam - qib LED tsav tsheb chips (xws li cov khoom siv hauv lub rooj teeb thiab teeb pom kev hauv tsev) feem ntau ua haujlwm ntawm -40℃thiab +85℃. Automotive- qib lossis kev lag luam- qib cov khoom lag luam (xws li cov khoom siv hauv tsheb teeb pom kev zoo thiab sab nraum zoov) tuaj yeem txhawb nqa -40℃rau +125 degree, nrog qee cov qauv high-end (xws li Infineon's LED tsav chips) ncav cuag qhov kub thiab txias txog li 150℃.
2. Yam tseem ceeb cuam tshuam:
Ntim Cov Khoom: QFN thiab DFN pob khoom muab cov cua sov zoo dua thiab ua haujlwm kub dua.
Power Density: High-power driver chips (e.g., >3W) xav tau kev tsim hluav taws xob tshwj xeeb; txwv tsis pub, qhov tseeb kev khiav hauj lwm kub yuav nce ho.
Environmental Compatibility: Automotive ua ntej - cov khoom nruab yuav tsum yog AEC-Q100 tau ntawv pov thawj, yuav tsum tau ua haujlwm ruaj khov thoob plaws txhua qhov kub ntawm -40℃txog 125℃.
3. Kev Tswj Xyuas Kev Kub Ntxhov Hauv cov ntawv thov, nti kub yuav tsum tau tswj los ntawm PCB tshav kub dissipation tsim (xws li tooj liab pours, thermal vias) los yog sab nraud kub dab dej los tiv thaiv lub teeb lwj los yog puas vim overheating. Nyob rau hauv siab - qhov kub thiab txias (xws li lub caij ntuj sov sab nraum zoov), nws raug nquahu kom cia qhov kub ntawm 10℃~ 15℃.
