Ndi chitukuko chosalekeza ndi kupita patsogolo kwa ukadaulo wamakono wazinthu zamagetsi, zinthu zamagetsi zikukula pang'onopang'ono kupita kumayendedwe a kuwala, zoonda, zazing'ono, zamunthu, zodalirika kwambiri komanso ntchito zambiri. Aluminium PCB idabadwa motsatira izi. Aluminiyamu PCB wakhala ankagwiritsa ntchito hybrid madera Integrated, magalimoto, ntchito zokha ofesi, mkulu-mphamvu zida zamagetsi, zida magetsi ndi madera ena ndi kutentha kwambiri dissipation, machinability wabwino, dimensional bata ndi ntchito magetsi.

Zolemba za aluminiyamupcb:
1. Chifukwa cha kukwera mtengo kwa zinthu zopangira, tiyenera kulabadira kukhazikika kwa magwiridwe antchito popanga kuti tipewe kutayika ndi zinyalala zomwe zimachitika chifukwa cha zolakwika zopanga.
2. The kuvala kukana kwa pamwamba pa zotayidwa pcb ndi osauka. Ogwiritsira ntchito njira iliyonse ayenera kuvala magolovesi pamene akugwira ntchito, ndi kuwatenga mofatsa kuti asakanda pamwamba pa mbale ndi aluminiyumu.
3. Ulalo uliwonse wa ntchito yamanja uyenera kuvala magolovesi kuti asakhudze malo ogwira ntchito a aluminiyamu pcb ndi manja kuti atsimikizire kukhazikika kwa ntchito yomanga pambuyo pake.
Kuthamanga kwapadera kwa gawo lapansi la aluminiyamu (gawo):
1. Kudula
l 1 ndi). Limbitsani kuyang'ana kwazinthu zomwe zikubwera (ziyenera kugwiritsa ntchito aluminiyamu pamwamba ndi pepala loteteza filimu) kuti muwonetsetse kudalirika kwa zinthu zomwe zikubwera.
l 2 ndi). Palibe mbale yophikira yomwe imafunikira mukatsegula.
l 3 ndi). Gwirani mofatsa ndi kulabadira chitetezo cha aluminiyamu m'munsi pamwamba (zoteteza filimu). Chitani ntchito yabwino yoteteza pambuyo potsegula zinthu.
2. Kubowola dzenje
l Kubowola magawo ndi ofanana ndi a FR-4 pepala.
L Kabowo kulolerana ndi okhwima kwambiri, 4OZ Cu kulabadira kulamulira m'badwo kutsogolo.
l Boolani mabowo ndi khungu lamkuwa.
3. Kanema wowuma
1) Kuyang'ana kwazinthu zomwe zikubwera: Filimu yoteteza ya aluminiyamu pansi iyenera kuyang'aniridwa musanagaye mbale. Ngati chiwonongeko chilichonse chikapezeka, chiyenera kupakidwa mwamphamvu ndi guluu wabuluu musanalandire chithandizo. Pambuyo processing watha, fufuzani kachiwiri pamaso akupera mbale.
2) Popera mbale: pamwamba mkuwa yekha ndi kukonzedwa.
3) Kanema: filimuyo iyenera kugwiritsidwa ntchito pazonse zamkuwa ndi aluminiyamu. Yang'anirani nthawi yapakati pa mbale yopera ndi filimu yosakwana mphindi imodzi kuti muwonetsetse kuti kutentha kwa filimu kumakhala kokhazikika.
4) Kuwomba m’manja: Samalirani kulondola kwa kuwomba m’manja.
5) Kuwonekera: Wolamulira wowonekera: 7 ~ 9 milandu ya guluu yotsalira.
6) Kupititsa patsogolo: kuthamanga: 20 ~ 35psi liwiro: 2.0 ~ 2.6m / min, wogwiritsa ntchito aliyense ayenera kuvala magolovesi kuti agwire ntchito mosamala, kuti asatengere filimu yoteteza ndi aluminiyamu m'munsi.
4. Mbale yoyendera
1) Mzere wa mzere uyenera kuyang'ana zonse zomwe zilimo mogwirizana ndi zofunikira za MI, ndipo ndikofunikira kwambiri kuti komiti yoyang'anira igwire ntchito mosamalitsa.
2) Pamwamba pazitsulo za aluminiyumu idzayang'aniridwa, ndipo filimu yowuma ya aluminiyumu pansi sidzakhala ndi filimu yogwa ndi kuwonongeka.
Zolemba zokhudzana ndi gawo lapansi la aluminiyamu:
A. Plate membala mbale kugwirizana ayenera kulabadira kuyendera, chifukwa palibe chabwino angatengedwe akupera kachiwiri, pakuti pakani akhoza anatola ndi sandpaper (2000 #) mchenga ndiyeno kutengedwa akupera mbale, Buku nawo ulalo wa mbaleyo ikugwirizana ndi ntchito yoyendera, chifukwa gawo loyenerera la aluminiyamu lakwera kwambiri!
B. Pankhani ya discontinuous kupanga, m'pofunika kulimbikitsa kukonza kuonetsetsa ukhondo kunyamula ndi thanki madzi, kuti kuonetsetsa kukhazikika ntchito pambuyo pake ndi liwiro kupanga.
