Ngokuthuthuka okuqhubekayo kanye nenqubekelaphambili yobuchwepheshe besimanje bemikhiqizo ye-elekthronikhi, imikhiqizo ye-elekthronikhi ikhula kancane kancane ibheke ekukhanyeni, okuncanyana, okuncane, okomuntu siqu, ukwethembeka okuphezulu kanye nemisebenzi eminingi.I-Aluminium PCB yazalwa ngokuhambisana nalo mkhuba.I-Aluminium PCB isetshenziswe kabanzi kumasekethe adidiyelwe ayi-hybrid, ezimotweni, ezishintshayo zehhovisi, izinto zikagesi ezinamandla amakhulu, imishini yokuphakela amandla kanye neminye imikhakha enokushabalaliswa kokushisa okuhle kakhulu, ukusebenziseka kahle, ukuzinza kwe-dimensional kanye nokusebenza kukagesi.

Ukusika → imbobo yokubhoboza → isithombe sokukhanya kwefilimu eyomile → ipuleti lokuhlola → ukuchopha → ukuhlola ukugqwala → imaski ye-solder eluhlaza → isikrini sikasilika → ukuhlola okuluhlaza → ukufafaza ngethini → ukwelashwa kwesisekelo se-aluminium → ipuleti lokubhoboza → ukuhlola kokugcina → ukupakisha → ukuthunyelwa
Amanothi e-aluminiumpcb:
1. Ngenxa yentengo ephezulu yezinto zokusetshenziswa, kufanele sinake ukumiswa kokusebenza enqubweni yokukhiqiza ukuvimbela ukulahleka kanye nemfucuza ebangelwa amaphutha okusebenza kokukhiqiza.
2. Ukumelana nokugqokwa kobuso be-aluminium pcb kubi.Abaqhubi benqubo ngayinye kufanele bagqoke amagilavu lapho besebenza, futhi bawathathe kancane ukuze bagweme ukunwaya ingaphezulu lepuleti nendawo eyisisekelo ye-aluminium.
3. Isixhumanisi ngasinye sokusebenza kwezandla kufanele sigqoke amagilavu ukuze sigweme ukuthinta indawo ephumelelayo ye-aluminium pcb ngezandla ukuze kuqinisekiswe ukuzinza komsebenzi wokwakha kamuva.
Ukugeleza kwenqubo ethile ye-aluminium substrate (ingxenye):
1. Ukusika
l 1).Qinisa ukuhlolwa kwezinto ezingenayo (kufanele kusetshenziswe indawo ye-aluminium eneshidi lefilimu elivikelayo) ukuze uqinisekise ukwethembeka kwezinto ezingenayo.
l 2).Alikho ipuleti lokubhaka elidingekayo ngemva kokuvulwa.
l 3).Bamba ngobumnene futhi unake ukuvikelwa kwe-aluminium base surface (ifilimu yokuzivikela).Yenza umsebenzi omuhle wokuvikela ngemuva kokuvula izinto.
2. Imbobo yokubhoboza
l Imingcele yokubhoboza iyafana naleyo yeshidi le-FR-4.
l Ukubekezelelana kwembobo kuqinile kakhulu, i-4OZ Cu inake ukulawula isizukulwane sangaphambili.
l Bamba izimbobo ngesikhumba sethusi phezulu.
3. Ifilimu eyomile
1) Ukuhlolwa kwezinto ezingenayo: Ifilimu yokuvikela ye-aluminium base surface kufanele ihlolwe ngaphambi kwepuleti lokugaya.Uma kukhona umonakalo otholakalayo, kufanele unamatheliswe ngokuqinile ngeglue eluhlaza okwesibhakabhaka ngaphambi kokwelashwa kwangaphambili.Ngemuva kokuthi ukucubungula sekuqediwe, hlola futhi ngaphambi kokugaya ipuleti.
2) Ipuleti yokugaya: indawo yethusi kuphela ecutshungulwayo.
3) Ifilimu: ifilimu izosetshenziswa kukho kokubili ithusi ne-aluminium base base.Lawula isikhawu phakathi kwepuleti lokugaya nefilimu ngaphansi kweminithi elingu-1 ukuze uqinisekise ukuthi izinga lokushisa lefilimu lizinzile.
4) Ukushaya izandla: Naka ukunemba kokushaya izandla.
5) Ukuchayeka: Irula yokuvezwa: 7~9 amacala eglue esele.
I-6) Ukuthuthukisa: ingcindezi: isivinini se-20 ~ 35psi: 2.0 ~ 2.6m / min, opharetha ngamunye kufanele agqoke amagilavu ukuze asebenze ngokucophelela, ukugwema ukunwaya ifilimu yokuzivikela kanye ne-aluminium base base.
4. Ipuleti lokuhlola
I-1) Indawo yomugqa kufanele ihlole konke okuqukethwe ngokuhambisana nezidingo ze-MI, futhi kubaluleke kakhulu ukwenza umsebenzi webhodi lokuhlola ngokuqinile.
2) Indawo engaphansi kwe-aluminium nayo izohlolwa, futhi ifilimu eyomile yesizinda se-aluminium akufanele ibe nefilimu ewayo kanye nokulimala.
Amanothi ahlobene ne-aluminium substrate:
A. Uxhumo lwepuleti lelungu lepuleti kufanele linake ukuhlolwa, ngoba akukho okuhle okungathathwa ukuze kugaywe futhi, ngoba ukuhlikihlwa kungakhethwa nge-sandpaper (2000#) isihlabathi bese kuthathwa ukuze kugaywe ipuleti, ukubamba iqhaza ngesandla kusixhumanisi ipuleti lihlobene nomsebenzi wokuhlola, ngoba izinga elifanelekayo le-aluminium substrate selithuthuke kakhulu!
B. Endabeni yokukhiqiza okungaqhubeki, kuyadingeka ukuqinisa ukulungiswa ukuze kuqinisekiswe ukuthutha okuhlanzekile kanye nethangi lamanzi, ukuze kuqinisekiswe ukusimama kokusebenza kanye nesivinini sokukhiqiza.
