3. Hloov pauv kev sib txuas
Siv FPC (hloov tau Circuit Court board) los txuas cov chaw tswj hwm loj thiab lub zog hluav taws xob module, nws tuaj yeem nqus cov khoom siv hluav taws xob ntau dua 3mm. Ib co photovoltaic inverter hloov cov hlau nrog FPC, thiab kev sib cheej tawm tsam ntawm kev txuas ntxiv ntawm ± 3m ω rau ib puag ncig -30 qib mus txog 85 degree.
3, kev tsim kho cov txheej txheem hloov kho: ib qho kev sib nrawm hauv cov txheej txheem tswj
1. Kev ua kom zoo ntawm cov kev xav sib dhos
Los ntawm kev hloov pauv cua daj cua dub nkhaus (120℃/ 60s → 15s → 180 Los ntawm cov txheej txheem no hloov kho, ib lub Hoobkas SMT tau nce qib dhau ntawm 0.8mm tuab PCBs los ntawm 78% mus rau 95%.
2. Hauv qab kev sib sau ua haujlwm tshiab
Los ntawm kev siv epoxy resin hauv qab filling nplaum thiab khoom siv nrog ib tug dispensing qhov tseeb ntawm BGA cov pob qij txha sib tw tuaj yeem nce 5 zaug. Tom qab ib qho cuab yeej sib txuas lus thov cov txheej txheem no, hom tsis ua tiav ntawm cov khoom thaum kuaj los ntawm kev sib koom ua ke nrog cov tub sib txuas lus tsis ua haujlwm.
3. Nto Kev Kho Mob Technology
Siv Tshuaj Lom Neeg Misees Palladium Kub (Enricing Kev Kho Mob, Cov Txheej Txheej Ntawm Nickel yog 0.0 m, uas tuaj yeem tswj qhov kev sib chwv tsis pub dhau 5m ω ntawm 150℃ib puag ncig. Ib qho chaw tsim khoom sib txuas tau txo cov kev tiv tauj tsis ua haujlwm ntawm lawv cov khoom los ntawm 8% rau 0.3% hauv qhov kub thiab txias thiab kub siab sim los ntawm cov txheej txheem no.
4, Txheej Txheem Qib Kev Tshuaj: Ntau Yam Kev Kawm Tawm Tsam Kev Ua Lag Luam
1. Thermal simulation thiab topology optimization
Los ntawm kev siv ansys orizpak rau thermal flow coupling simulation, qhov chaw nyob ntawm hotspots tuaj yeem kwv yees tau. Ib tug neeg rau zaub mov tsim tau hloov kho cov xov raws li simulation results, txo qis qhov siab tshaj plaws ntawm tus PCB los ntawm 118℃thiab txo qis cov nqi tsis ua tiav los ntawm 62%.
2. Kev tsim kho cov khoom siv hluav taws xob
Tsim kom muaj qhov thermal cov ntaub ntawv kev ua tau zoo database muaj 237 cov ntaub ntawv kom ua tiav cov kev tsis siv neeg suav ntawm CTE txuam degree. Ib qho chaw lag luam Aerospace tau ua kom luv cov khoom siv xaiv txij li 72 teev mus rau 8 teev thiab txhim kho cov khoom sib piv rau 92% los ntawm cov kab ke no.
