Ngophuhliso oluqhubekayo kunye nenkqubela phambili yetekhnoloji yemveliso ye-elektroniki yale mihla, iimveliso zombane zikhula ngokuthe ngcembe ukuya kwicala lokukhanya, elibhityileyo, elincinci, elenzelwe wena, ukuthembeka okuphezulu kunye nemisebenzi emininzi. I-Aluminiyam PCB yazalwa ngokuhambelana nalo mkhwa. I-Aluminiyam PCB isetyenziswe ngokubanzi kwiisekethe ezidibeneyo ezidibeneyo, iimoto, i-automation ye-ofisi, izixhobo zombane eziphezulu zamandla, izixhobo zombane kunye nezinye iindawo ezinokutshatyalaliswa kobushushu, ukucwangciswa kakuhle, ukuzinza komda kunye nokusebenza kombane.

Ukusika → umngxuma wokugrumba → ifilimu eyomileyo yokwenza umfanekiso wokukhanya → ipleyiti yokuhlola → ukuchola → ukuhlolwa kokugqwala → i-soldermask eluhlaza → isikrini sesilika → uhlolo oluluhlaza → ukutshiza ngetoti → isiseko se-aluminiyam yonyango → ipleyiti yokubhoboza → ukuhlolwa kokugqibela → ukupakishwa → ukuthunyelwa
Amanqaku e-aluminiyampcb:
1. Ngenxa yexabiso eliphezulu lezinto eziluhlaza, kufuneka sinikele ingqalelo kwimigangatho yokusebenza kwinkqubo yokuvelisa ukuthintela ilahleko kunye nenkunkuma ebangelwa yimpazamo yokusebenza kwemveliso.
2. Ukumelana nokunxiba komphezulu we-aluminium pcb kubi. Abaqhubi benkqubo nganye kufuneka banxibe iiglavu xa besebenza, kwaye bazithathe ngobunono ukuphepha ukukrwela umphezulu wepleyiti kunye nesiseko se-aluminium.
3. Ikhonkco ngalinye lomsebenzi wezandla kufuneka linxibe iiglavu ukuphepha ukubamba indawo esebenzayo ye-aluminium pcb ngezandla zokuqinisekisa ukuzinza komsebenzi wokwakha kamva.
Inkqubo ethile yokuhamba kwe-aluminiyam substrate (inxalenye):
1. Ukusika
l 1). Ukuqinisa ukuhlolwa kwezinto ezingenayo (kufuneka usebenzise i-aluminium surface kunye nephepha lefilimu elikhuselayo) ukuqinisekisa ukuthembeka kwezinto ezingenayo.
l 2). Akukho pleyiti yokubhaka efunekayo emva kokuvulwa.
l 3). Phatha ngobumnene kwaye ubeke ingqalelo ekukhuselweni kwesiseko se-aluminium (ifilimu yokukhusela). Yenza umsebenzi omhle wokukhusela emva kokuvula izinto.
2. Umngxuma wokwemba
l Iiparamitha zokugaya ziyafana nezo ze-FR-4 sheet.
l Ukunyamezelana kwe-Aperture kungqongqo kakhulu, i-4OZ Cu ingqalelo ukulawula isizukulwana ngaphambili.
l Gqoka imingxuma ngesikhumba sobhedu phezulu.
3. Ifilimu eyomileyo
I-1) Ukuhlolwa kwezinto ezingenayo: Ifilimu ekhuselayo yesiseko se-aluminium kufuneka ihlolwe ngaphambi kokuba iplate yokugaya. Ukuba kukho nawuphi na umonakalo ofunyenweyo, kufuneka ugxininiswe ngokuqinileyo ngeglue eluhlaza okwesibhakabhaka ngaphambi kokuba unyango lwangaphambili. Emva kokuba inkqubo igqityiwe, jonga kwakhona phambi kokuba ugaye ipleyiti.
2) Ipleyiti yokugaya: kuphela indawo yobhedu icutshungulwa.
3) Ifilimu: ifilimu iya kusetyenziswa kwiindawo zombini zobhedu kunye ne-aluminium. Lawula ikhefu phakathi kwepleyiti yokugaya kunye nefilimu engaphantsi komzuzu we-1 ukuqinisekisa ukuba ukushisa kwefilimu kuzinzile.
4) Ukuqhwaba izandla: Nika ingqalelo ukuchaneka kokuqhwaba.
I-5) I-Exposure: irula ye-Exposure: 7 ~ 9 iimeko zeglue eseleyo.
I-6) Ukuphuhlisa: uxinzelelo: i-20 ~ 35psi isivinini: 2.0 ~ 2.6m / min, umqhubi ngamnye kufuneka agqoke iiglavu ukuze asebenze ngokucophelela, ukuphepha ukukrazula ifilimu ekhuselayo kunye nesiseko se-aluminium.
4. Ipleyiti yokuhlola
1) Umgca womgca kufuneka uhlolisise zonke iziqulatho ngokuhambelana neemfuno ze-MI, kwaye kubaluleke kakhulu ukwenza umsebenzi webhodi yokuhlola ngokungqongqo.
2) Isiseko sesiseko se-aluminium siya kuhlolwa kwakhona, kwaye ifilimu eyomileyo yesiseko se-aluminium ayiyi kuba nefilimu ewayo kunye nomonakalo.
Amanqaku anxulumene ne-aluminium substrate:
A. Plate ilungu uqhagamshelo ipleyiti kufuneka anikele ingqalelo ekuhlolweni, kuba akukho nto ilungileyo inokuthatyathwa ukuba usila kwakhona, kuba ukukhuhla unokuthathwa nge sandpaper (2000 #) isanti kwaye emva koko kuthathwe ukugaya ipleyiti, inxaxheba ngesandla kwikhonkco ye ipleyiti inxulumene nomsebenzi wokuhlola, kuba i-aluminium substrate ye-aluminiyam izinga elifanelekileyo liphuculwe kakhulu!
B. Kwimeko yokuveliswa kokuyeka, kuyimfuneko ukuqinisa ukugcinwa ukuqinisekisa ukuhanjiswa okucocekileyo kunye netanki yamanzi, ukwenzela ukuba kuqinisekiswe ukuzinza komsebenzi kamva kunye nesantya sokuvelisa.
