Sebaka sa Aluminium ke sethala sa koporo se thehiloeng tšepe se lahloa ka ts'ebetso e ntle ea mocheso. Ke lintho tse kang tsa litlolo tse kang tsa fiber tsa elektroniki kapa lisebelisoa tse ling tse hlahisoang ke Resino, e le 'ngoe. Kangoin potoloho e hlahisa ts'ebetso ea aluminium substrate le kalafo ea thepa.
Ts'ebetso ea Aluminium
1.Exceler
Lijana tsa Copper-tsa Clad-Clad li na le ts'ebetso e ntle ea mocheso, e leng karolo e hlahelletseng ea mofuta ona oa poleiti ena. The PCB made of it can not only effectively prevent the working temperature of the components and substrates loaded on it from rising, but also quickly heat generated by power amplifier components, high power components, large circuit power switches and other components. E boetse e tsamaisoa ka lebaka la letsoalo la eona le nyane, boima ba eona (2,7g / cm3), anti-oxida. Ho hanela ho hafatsa molumo oa aluminium e kentsoeng ke "
2. Emplaction "le boleng ba mochini
Li-lamuter-Clad tse sebetsang li na le matla le ho ba thata ho tsona, tse leng betere ho feta li-clarate tse thata tsa li-colin-clalick. E ka bona tlhahiso ea liboto tse kholo tse hatisitsoeng ka tšepe, 'me e loketse haholo likarolo tse boima tse ntseng li eketseha ka bongata. Ntle le moo, subrate e ngata e boetse e na le bofubelu bo botle, 'me e ka bokelloa ka karoloana e seng ea metsi ho PCB e thehiloeng ho eona, ha a ntse a sotlehile.
3.Hagh botsitso
Bakeng sa mabone a fapaneng a koporong, ho na le bothata ba keketseho ea mocheso (botsitso bo hlasimollang, e amang boleng ba masoba a masene le wiring. Lebaka le ka sehloohong ke hore li-coefficents tsa mela ea lipolanete li fapane, tse bonolo ho etsa phapang ea koporo le lesoba la koena ho khaola kapa ho senyehile. Ka mokhoa o nepahetseng oa ho koata ka letsoho oa aluminium o pakeng tsa substrate, o haufi le ho tšoara boleng le ho tšepahala ho e hatisitsoeng.
Phekolo ea holimo ea Boitsebiso ba Aluminium
1. Disoiling
Bokaholimo ba poleiti e thehiloeng ho aluminim bo koahetsoe ka karolo ea oli nakong ea ts'ebetso le lipalangoang, 'me e tla hloekisoa pele e sebelisoa. Molao-motheo ona o lokela ho sebelisa peterole (e akaretsang ea ho sesa, e ka qhibilihang, ebe u sebelisa moemeli oa ho hloekisa metsi ho tlosa letheba la oli. Hlatsoa bokaholimo ka metsi a phallang ho e hloekisa hape e se na marotholi a metsi.
2. Deprease
Sebaka sa Aluminium ka mor'a kalafo e kaholimo li ntse li sa etsetsoa mafura. Ho e tlosa ka ho felletseng, ho e soabisa ka hydroxide ea matla a Alkali sodium ka metsotso e 5, ebe u hlatsoa ka metsi a hloekileng.
3. Alkaline eshing. Bokaholimo ba aluminium poleiti e le thepa ea motheo e lokela ho ba le bothata bo itseng. Ho tloha ka aluminium e ka tlase ea filimi ea aluminium axide holim 'a thepa ea aluminium Ntle le moo, lintho tse ling le litlatsetso li hloka ho eketsoa tharollo ea mokokotlo oa ho fihlela merero e latelang.
4. Chemical polishing (e khethollang). Hobane chelete ea aluminium e na le lisebelisoa tse ling tse nang le litlolo, ho bonolo ho etsa metsoako e sa kopaneleng ka har'a ts'ebetso ea litlokotsebe, kahoo metsoako e meholo e ka hlahlojoa. Ho latela liphetho tsa lihlahlobo, lomisetsa tharollo e loketseng, ebe li beha aluminium e ka qobisitsoeng ka thata tharollo ea aluminium e hloekile ebile e benyang.
