Qhov tseem ceeb ntawm cov tshuab hluav taws xob hauv cov tshuab hluav taws xob hauv tag nrho lub tsheb yog nce ib hnub dhau hnub. Los ntawm cov kev pab tsav tsheb qib siab (Adas) mus rau hauv tsheb lomzeej kev lom zem, cov hluav taws xob ua haujlwm tau dhau los ua cov tsheb tsis tseem ceeb ntawm cov tsheb niaj hnub no. Raws li cov cab kuj tseem ceeb ntawm cov hluav taws xob hluav taws xob, kev ua tau zoo ntawm cov txiag hluav taws xob ncaj qha cuam tshuam rau kev ntseeg tau, kev ruaj khov, thiab lub neej ntawm cov tshuab hluav taws xob hauv tshuab hluav taws xob. Txawm li cas los xij, kev ua haujlwm ib puag ncig ntsib los ntawm automotive Electronic luam cov laug cam tsis muaj kev cuam tshuam, thiab lwm yam kev xav tau ntawm kev xaiv ntawm cov ntawv luam tawm hluav taws xob.
1, Xaiv Automotive Electronic Luam Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob
Kev xaiv ntawm substrate
Lub substrate yog cov tseem ceeb ntawm cov ntawv luam tawm hluav taws xob, thiab nws cov kev ua tau zoo cuam tshuam, lub zog ua zog ntawm cov khoom siv hluav taws xob. Cov khoom siv hluav taws xob uas siv hluav taws xob uas nquag siv hluav taws xob cov ntawv sau ua haujlwm nrog cov hauv qab no:
Epoxy Resin iav Fiber (Fr-4)
Fr -} Yog tam sim no yog ib qho ntawm cov ntawv luam tawm dav siv cov khoom lag luam, nrog kev ua tau zoo zog thiab kev ua haujlwm hluav taws xob, thiab tus nqi qis. Txawm li cas los xij, FR-4 muaj cov kub kub tsis kam thiab nws lub sijhawm ua haujlwm ntev feem ntau tsis tshaj 130 Degree C. Yog li ntawd, rau kev ua haujlwm ntau dua, FR-4 tsis yog qhov kev xaiv zoo.
Polyimide (pi)
Polyimide substrates muaj cov cua sov zoo heev, tshuaj lom neeg ua haujlwm kub, thiab kev ua haujlwm ntev dua, ua rau nws muaj kev sib kis tau yooj yim, ua rau muaj kev sib tw siab. Txawm li cas los xij, tus nqi siab thiab ua nyuaj thiab kev nyuaj ntawm polyimide substrates txwv lawv siv hauv qee qhov kev thov daim ntawv thov.
Polytetrafluoroethylene (PTFE)
Polytetrafluoroethylene substrate muaj dielectric tas li thiab dielectric ploj, ua rau nws high {0 zaus} zaus. Tsis tas li ntawd, PTFE substrate muaj cov cua sov tsis kam thiab tshuaj lom neeg ruaj khov. Txawm li cas los xij, PTFE substrates muaj tsawg cov neeg kho tshuab zog thiab nyuaj rau kev ua haujlwm xws li cov khoom siv uas siv tau los txhim kho lawv cov khoom siv.
Kev kub siab Epoxy Resin (High TG FR-4)
Epoxy Resin substrates nrog lub iav hloov cua txias (TG) yog ib qho kev xaiv ib qho kev xaiv hauv kev thaj chaw ntawm cov khoom siv hluav taws xob hauv kev lag luam. Feem ntau, epoxy resin substrates nrog ib tug tg siab dua 170℃c tuaj yeem ua kom tau raws li cov kev xav tau ntawm cov kev lag luam hauv hluav taws xob feem ntau. Piv nrog dectern dist diven fr-4, siab tg fr-4 substrates muaj kub siab dua thiab tshuab zog, tab sis tus nqi kuj tseem muaj siab.
2, xaiv kev xaiv ntawm cov khoom npog
Cov npog txheej txheej yog tsuas yog siv los tiv thaiv cov npoo ntawm cov ntawv luam tawm hluav taws xob, tiv thaiv kev puas tsuaj tshuab thiab tshuaj lom neeg. Rau automotive cov hluav taws xob hluav taws xob cam, xaiv cov npog txheej txheej yuav tsum xav txog cov hauv qab no:
siab - kub tsis kam
Cov khoom npog yuav tsum muaj peev xwm tswj tau ruaj khov nyob hauv ib puag ncig kub, tiv thaiv kev muag khoom, deforming ntawm qhov kub siab.
Tshuaj lom neeg Corrosion Desistance Kev ua tau zoo
Cov ntaub ntawv npog cov ntaub ntawv xav tau kom muaj tshuaj lom neeg tshuaj tiv thaiv zoo los tiv thaiv corrosion rau hauv ib puag ncig.
Neeg Kho Tshuab Muaj Zog
Cov ntaub ntawv npog uas xav tau muaj cov neeg siv lub zog txaus kom tiv thaiv kev tawg lossis tev hauv kev co lossis kev cuam tshuam.
Cov npog txheej txheej muaj cov npog cov khoom siv muaj cov txheej txheem polyimide, cov txheej txheej acrylic cob cov nqaij, thiab epoxy cob cov txheej txheej. Cov txheej txheem txheej txheem polyimide muaj cov kub tau zoo heev thiab tshuaj ruaj khov, tab sis lawv cov nqi yog qhov siab; Acrylic resin txheej muaj tus nqi qis dua, tab sis kub siab kuj; Epoxy Resin Txheej muaj qhov ua tau zoo ua tau zoo thiab haum rau feem ntau cov ntawv thov hluav taws xob feem ntau.
3, xaiv cov ntaub ntawv tshaj tawm
Cov khoom xaiv tsuas cuam tshuam rau kev ua tau hluav taws xob thiab corrosion tsis kam ntawm cov ntawv cim hluav taws xob. Cov khoom siv cov khoom lag luam xws li tooj liab ntawv ci thiab npib kub plating.
Tooj liab ntawv nyiaj
Tooj liab ntawv sib tov yog cov khoom siv uas siv tau ntau hauv cov khoom siv hluav taws xob sib xyaw ua ke, nrog kev ua haujlwm zoo thiab cov khoom siv neeg kho mob. Txawm li cas los xij, Tooj liab ntawv nyiaj yog qhov raug tshuaj lom neeg, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig huab cua. Yog li ntawd, hauv automotive Electronic luam hluav taws xob cov laug cam, tooj liab feem ntau yuav tsum muaj kev kho kom nto, thiab lwm yam, txhawm rau txhim kho nws cov corrosion tsis kam.
Nickel Gold Txheej
Nickel gold txheej muaj zoo corrosion tsis kam thiab coj kev tiv thaiv, haum rau kev siv hauv cov av noo lossis cov tshuaj muaj kuab. Txawm li cas los xij, tus nqi ntawm Nickel Kub plating yog siab thiab cov txheej txheem yog complex, feem ntau yog siv rau kev kho tsheb hluav taws xob luam tawm.
