Txuj: IEC 60068-2-78
Advanced Method: HAST (130℃/ 85% RH, siab -siab nrawm, ntsuas lub voj voog tuaj yeem luv rau 96 teev)
3. Kev yees duab: Kev ntsuam xyuas lub teeb ruaj khov ntawm cov khoom siv los ntawm kev simulating ultraviolet, pom, thiab infrared lub teeb los ntawm lub hnub ci siv cov khoom siv hluav taws xob.
(1) Ultraviolet Aging (QUV) Simulates UV band ntawm lub hnub ci siv lub teeb fluorescent UVA-340. Haum rau plastics, coatings, thiab textiles. Cov Qauv: ASTM G154, GB / T 16422.3
(2) Xenon Lamp Aging Simulates tag nrho - spectrum tshav ntuj, suav nrog tshuaj tsuag thiab lub voj voog tsaus. Ze rau qhov chaw sab nraum zoov tiag tiag. Haum rau tsheb sab nrauv, cov khoom siv hauv tsev, thiab kev tshaj tawm sab nraum zoov. Cov Qauv: ISO 4892-2, GB / T 16422.2
4. Salt Spray Aging Simulates cov txheej txheem hlau corrosion nyob rau hauv marine los yog ntug hiav txwv ib puag ncig los ntawm tsis tu ncua txau ib 5% NaCl ntsev tov tov. Khoom Siv Tau: Hlau vaj tse, connectors, fasteners
Kev Xeem Hom: Tsis Siv Tshuaj Ntsev (NSS), Acetic Acid Salt Spray (AASS), Copper Accelerated Acetic Acid Salt Spray (CASS)
Daim ntawv pov thawj: ISO 9227, GB / T 10125
Kev ntsuas ntsuas: Lub sij hawm rau xeb zoo li, corrosion cheeb tsam qib
5. Thermal Cycling Test (TCT)
Simulates qaug zog kev puas tsuaj los ntawm thermal expansion thiab contraction los ntawm kev rov hloov ntawm qhov kub siab thiab qis qis.
Khoom Siv Tau: PCB solder pob qij txha, BGA pob khoom, khoom siv hluav taws xob tsheb
Ntau yam: -65℃↔ +150 degree, 500 ~ 1000 cycles
Tus qauv siv: JESD22-A104
Cov ntsiab lus tseem ceeb: cua sov / cua txias, lub sijhawm nyob, tus lej ntawm lub voj voog
6. HAST (High Accelerated Temperature and Humidity Stress Test)
Kev ntsuas nrawm nyob rau hauv qhov kub thiab txias, kev kub siab, thiab cov av noo siab, tshwj xeeb tsim los ntsuas cov dej tsis kam ntawm cov khoom siv semiconductor.
Cov xwm txheej zoo: 130 degree, 85% RH, tsis yog -condensing xeev
Qhov zoo: Ntau tshaj 10 npaug ntau dua li kev sim THB ib txwm muaj
Tus qauv siv: JESD22-A101
Daim ntawv thov Scenario: Chip pob kev ntseeg tau pov thawj
7. Ntau-Kev Sib Txuas Kev Nyuaj Siab Hauv kev siv cov tswv yim, ntau yam ib puag ncig feem ntau ua haujlwm ua ke, yog li ntawd, yuav tsum tau tsim cov qauv kev sim sib xyaw:
HALT (High Accelerated Life Test): Muab qhov kub thiab txias hloov, ntau -axis vibration, thiab voltage fluctuation kom sai sai nthuav tawm cov teeb meem tsim.
HASS (High Accelerated Stress Screening): Siv los tshuaj xyuas cov khoom uas ua tsis tau thaum ntxov thaum lub sijhawm tsim khoom.
Kev sib xyaw ua ke: HAST + TCT + Kev vibration, haum rau automotive - qib hluav taws xob modules.
