Gawo la aluminium ndi copper copy clad limalima ndi ntchito yabwino yotentha. Ndi zinthu zopangidwa ndi nsalu ngati zamagetsi kapena zida zina zolimbikitsira zophatikizika ndi zotumphukira, chimodzi, ndi zina zomata. Gulu la KangXin limayambitsa ntchito ya aluminium gawo lapansi ndi kuthandizira kwa zinthu.
Ma aluminiyamu
1.excemanger kutentha magwiridwe antchito
Mapulogalamu a aluminium-copper-curper amakhala ndi magwiridwe antchito abwino, omwe ndiye gawo lotchuka kwambiri la mbale yamtunduwu. PCB yopangidwa ndi iyo siyongoletsa kutentha kwazinthu ndi magawo magawo ake odzaza ndi kuwuluka, komanso kuthira msanga ndi mphamvu, mphamvu zazikuluzikulu, mphamvu zazikulu ndi zigawo zina. Amagawidwanso chifukwa cha kachulukidwe kakang'ono, kulemera kowala (2.7g / cm3), otsutsa-oxadation, motero wakhala wotsika mtengo kwambiri komanso pepala lalikulu kwambiri. Kukana kwa majermini okwanira a aluminium a aluminiyamu ndi 1.10 ℃ / w ndi matenthedwe ndi 2.8 ℃ / w, omwe amasintha kwambiri pa waya wamkuwa.
2.Poyendetsa bwino komanso mtundu wamakina
Aluminim-Copy curper-clad amakhala ndi mphamvu zapamwamba kwambiri komanso kulimba kwambiri, zomwe zili bwino kwambiri kuposa zokhazikika zokhala ndi mkuwa zokhazikika komanso zopindika za ceramic. Itha kuzindikira kupanga kwa matabwa akuluakulu osindikizidwa pazitsulo za zitsulo, ndipo ndizoyenera makamaka pakukweza zinthu zolemera pazinthu zotere. Kuphatikiza apo, gawo la aluminiyamu limakhalanso lotayika, ndipo limatha kusonkhanitsidwa ndikukonzedwa pamtunda, okhazikika, ndi zina zopindika.
3.high clumation kukhazikika
Kwa Copper Copper Clad Amiyala, pamakhala vuto la kuwonjezeka kwa mafuta (mawonekedwe a matenthedwe), makamaka kukulira kwa matenthedwe mu chitsogozo cha makulidwe (z-axis) ya mabowo, omwe amathandizira. Chifukwa chachikulu ndikuti mzere wokulirapo wa mbale ndi zosiyana, monga mkuwa, ndi mzere wokulirapo wa gulu la epoxy ndi losiyana kwambiri, ndikupangitsa kuti kuzungulira kwa mkuwa ndi kuwonongeka. Kukula kwa mzere wa magawo a aluminium kuli pakati, ndizochepa kwambiri kuposa gawo lalikululi, ndipo ali pafupi ndi mzere wokulirapo, zomwe zimapangitsa kuti zisadalirire.
Pamaso othandizira a aluminium
1. Zowonongeka
Pamwamba pa mbale ya aluminium yolumikizidwa ndi mafuta osanjikiza mafuta nthawi yogwiritsira ntchito ndi mayendedwe, ndipo iyenera kutsukidwa musanagwiritse ntchito. Mfundo yake ndikugwiritsa ntchito mafuta a petulo (generalviation aviation) ngati zosungunulira) monga solvel, yomwe imatha kusungunuka, kenako gwiritsani ntchito yoyeretsa madzi kuti ichotse madontho ambiri. Muzimutsuka pansi ndi madzi othamanga kuti ikhale yoyera komanso yopanda madontho amadzi.
2. Tsanja
Gawo la aluminium pambuyo pa chithandizo chomwe tafotokozawa chilipobe mafuta osakhazikika pamtunda. Kuti muchotse kwathunthu, ndi yokhazikika ndi alkali sodium hydroxide pa 50 ° c kwa mphindi 5, kenako ndikutsuka ndi madzi oyera.
3. Alkalines alch. Pamwamba pa mbale ya aluminiyamu monga momwe maziko amayenera kukhala ndi mtundu wina. Popeza magawo a aluminiyamu ndi aluminiyamu o oxide oxide osanjikiza ndi zinthu zonse ziwiri ndi zida zonse za alumminic, zomwe zimapangitsa kuti zinthu zipinda za aluminium zitha kugwiritsidwa ntchito pogwiritsa ntchito mankhwalawa. Kuphatikiza apo, zinthu zina komanso zowonjezera zimafunikira kuwonjezeredwa ku yankho la rouguet kuti mukwaniritse zolinga zotsatirazi.
4.. Kupukutira kwa mankhwala (kuthira). Chifukwa zinthu za aluminium zimakhala ndi zitsulo zina zodetsa, ndizosavuta kupanga zinthu zopanda mafuta zomwe zimatsatira pamtunda wa gawo lapansi panthawi yopanga zopangira, motero mankhwala osokoneza bongo omwe amapangidwa pansi ayenera kusanthula. Malinga ndi zomwe zinawunikira, konzekerani njira yopumira yopumira, ndikuyika gawo lokhazikika mu njira yopumutsira kuti muwonetsetse nthawi inayake, kuti nthaka ya aluminium ndi yoyera komanso yopepuka.
