Aluminiyamu gawo lapansi ndi chitsulo chopangidwa ndi mkuwa chovala laminate chokhala ndi ntchito yabwino yotaya kutentha. Ndi chinthu chonga mbale chopangidwa ndi nsalu yamagetsi yamagalasi amagetsi kapena zida zina zolimbikitsira zomwe zimayikidwa ndi utomoni, utomoni umodzi, ndi zina zotere monga zomatira zomata, zophimbidwa ndi zojambulazo zamkuwa kumbali imodzi kapena mbali zonse ziwiri ndikusindikiza kotentha, komwe kumatchedwa aluminium- mbale yokhala ndi mkuwa. Kangxin Circuit imayambitsa kagwiritsidwe kagawo kakang'ono ka aluminiyamu komanso kasamalidwe ka zinthu.
Aluminium gawo lapansi ntchito
1.Ntchito yabwino kwambiri yowononga kutentha
Zovala za aluminiyamu zopangidwa ndi mkuwa zimakhala ndi ntchito yabwino kwambiri yochepetsera kutentha, yomwe ndi mbali yodziwika kwambiri ya mbale iyi. PCB yopangidwa ndi izo sizingalepheretse bwino kutentha kwa zigawozi ndi magawo omwe amanyamulidwa kuti asatuluke, komanso mofulumira kutentha komwe kumapangidwa ndi zigawo za amplifier mphamvu, zigawo zamphamvu zamphamvu, masiwichi akuluakulu ozungulira magetsi ndi zigawo zina. Amagawidwanso chifukwa cha kachulukidwe kakang'ono, kulemera kwake (2.7g / cm3), anti-oxidation, ndi mtengo wotsika mtengo, kotero wakhala wosunthika kwambiri komanso wochuluka kwambiri wa pepala lopangidwa ndi zitsulo zopangidwa ndi zitsulo zopangidwa ndi mkuwa. Kukaniza kwamafuta kwa gawo lapansi la aluminiyamu ya insulated ndi 1.10 ℃/W ndipo kukana kwamafuta ndi 2.8 ℃/W, komwe kumathandizira kwambiri kusakanikirana kwa waya wamkuwa.
2.Kupititsa patsogolo mphamvu ndi khalidwe la makina
Zovala zokhala ndi aluminiyamu zokhala ndi mkuwa zimakhala ndi mphamvu zamakina komanso zolimba, zomwe zimakhala zabwino kwambiri kuposa zokhala ndi utomoni wopangidwa ndi mkuwa ndi magawo a ceramic. Ikhoza kuzindikira kupanga matabwa akuluakulu osindikizidwa pazitsulo zazitsulo, ndipo ndizofunikira makamaka kuyika zigawo zolemera pazigawo zotere. Kuonjezera apo, gawo lapansi la aluminiyamu limakhalanso ndi flatness wabwino, ndipo likhoza kusonkhanitsidwa ndikukonzedwa pa gawo lapansi pogwiritsa ntchito nyundo, riveting, ndi zina zotero. zochokera mkuwa atavala laminate sangathe .
3.High dimensional bata
Pakuti laminates zosiyanasiyana mkuwa atavala, pali vuto la kukula matenthedwe (dimensional bata), makamaka matenthedwe kukula mu makulidwe malangizo (Z-olamulira) wa bolodi, zomwe zimakhudza khalidwe la mabowo metallized ndi mawaya. Chifukwa chachikulu ndi chakuti ma coefficients owonjezera a mbale ndi osiyana, monga mkuwa, ndi mzere wowonjezera wowonjezera wa epoxy glass fibercloth substrate ndi 3. Kukula kwa mzere wa ziwirizo ndi kosiyana kwambiri, zomwe n'zosavuta kuyambitsa kusiyana kwa matenthedwe kukula kwa gawo lapansi, kuchititsa dera mkuwa ndi dzenje metallized kusweka kapena kuonongeka. Mzere wowonjezera wowonjezera wa gawo lapansi la aluminiyamu uli pakati, ndi wocheperako kwambiri kuposa gawo lonse la resin, ndipo uli pafupi ndi mzere wokulirapo wamkuwa, womwe umathandizira kuwonetsetsa kudalirika ndi kudalirika kwa dera losindikizidwa.
Chithandizo chapamwamba cha aluminiyumu gawo lapansi
1. Kuchepetsa thupi
Pamwamba pa mbale yopangidwa ndi aluminiyumu imakutidwa ndi mafuta osanjikiza panthawi yokonza ndi kuyendetsa, ndipo iyenera kutsukidwa musanagwiritse ntchito. Mfundo yake ndi kugwiritsa ntchito mafuta (mafuta oyendetsa ndege) monga chosungunulira, chomwe chimatha kusungunuka, ndiyeno gwiritsani ntchito choyeretsa chosungunuka m'madzi kuti muchotse madontho amafuta. Tsukani pamwamba ndi madzi oyenda kuti pakhale paukhondo komanso opanda madontho amadzi.
2. Kuchepetsa mafuta
Aluminiyamu gawo lapansi pambuyo pa mankhwalawa ali ndi mafuta osachotsedwa pamwamba. Kuti muchotse kwathunthu, zilowerereni ndi amphamvu alkali sodium hydroxide pa 50 ° C kwa mphindi zisanu, ndiyeno muzimutsuka ndi madzi oyera.
3. Kupaka zamchere. Pamwamba pa mbale ya aluminiyamu monga maziko ake ayenera kukhala ndi roughness. Popeza zitsulo zotayidwa gawo lapansi ndi zotayidwa okusayidi filimu wosanjikiza pamwamba ndi zipangizo amphoteric, pamwamba pa zotayidwa m'munsi zakuthupi akhoza roughened ntchito acidic, zamchere kapena gulu alkaline njira yothetsera. Kuonjezera apo, zinthu zina ndi zowonjezera ziyenera kuwonjezeredwa ku yankho la roughening kuti akwaniritse zolinga zotsatirazi.
4. Mankhwala kupukuta (kuviika). Chifukwa chakuti aluminiyamu m'munsi zinthu zili ndi zitsulo zonyansa, n'zosavuta kupanga mankhwala inorganic kuti amamatira pamwamba pa gawo lapansi pa roughening ndondomeko, kotero inorganic mankhwala opangidwa pamwamba ayenera kusanthula. Malinga ndi zotsatira za kusanthula, konzani njira yoyenera yoviyira, ndikuyika gawo lapansi la aluminiyamu yolimba mu njira yoviika kuti mutsimikizire nthawi inayake, kuti pamwamba pa mbale ya aluminiyamu ikhale yoyera komanso yonyezimira.
