Aluminium PCB Manufacturing process

Aluminium PCB Manufacturing processTs'ebetso ea ho etsa aluminium PCB e nang le OSP top finish: Ho seha→Ho cheka → Potoloho → Acid/alkaline etching→ Solder Mask→Silkscreen→V-cut→PCB Test→OSP→FQC→FQA→Packing→Delivery.

Mokhoa oa ho etsa aluminium PCB e nang le HASL e qetellang ka holim'a metsi: Ho Seha → Ho cheka → Potoloho → Acid/alkaline etching → Solder Mask→ Silkscreen→HASL→V-cut→PCB Test→FQC→FQA→Packing→Delivery.

YMSPCB e ka fana ka PCB ea mantlha ea aluminium ka mokhoa o ts'oanang oa ho qeta bokaholimo joalo ka FR-4 PCB: Ho qoelisoa Khauta / tšesaane / silevera, OSP, jj.

Ha ho etsoa aluminium PCB, ho eketsoa karolo e tšesaane ea dielectric pakeng tsa lera la potoloho le lera la motheo. Lera lena la dielectric le sireletsa motlakase ka bobeli, hammoho le ho tsamaisa mocheso. Ka mor'a ho eketsa lesela la dielectric, sekhahla sa potoloho kapa foil ea koporo e kenngoa

Hlokomela

1. Beha mapolanka ka har'a cage-shelf kapa u li arole ka pampiri kapa lipampiri tsa polasetiki ho qoba likhahla nakong ea lipalangoang tsa tlhahiso eohle.

2. Ho sebelisa thipa ho phunya lesela le sirelelitsoeng ts'ebetsong leha e le efe ha ho lumelloe nakong ea tlhahiso eohle.

3. Bakeng sa mapolanka a lahliloeng, thepa ea motheo e ke ke ea phunngoa empa e tšoauoa feela ka "X" ka pene ea oli.

4. Kakaretso ea tlhahlobo ea mohlala ke ea bohlokoa hobane ha ho na mokhoa oa ho rarolla bothata ba mohlala ka mor'a ho etching.

5. Etsa licheke tsa 100% tsa IQC bakeng sa liboto tsohle tsa kantle ho naha ho latela maemo a k'hamphani ea rona.

6. Bokella liboto tsohle tse nang le bothata hammoho (joalo ka 'mala o lerootho le mengoapo ea bokaholimo ba AI) hore bo sebetsanoe hape.

7. Bothata bofe kapa bofe nakong ea tlhahiso bo tlameha ho tsebisoa basebetsi ba amanang le theknoloji ka nako e lokelang ho rarolloa.

8. Mekhoa eohle e tlameha ho sebetsoa ka thata ho latela litlhoko.

Liboto tsa potoloho tse hatisitsoeng tsa aluminium li boetse li tsejoa e le li-PCB tsa tšepe 'me li entsoe ka li-laminate tse thehiloeng ka tšepe tse koahetsoeng ke likarolo tsa potoloho ea koporo. Li entsoe ka lipoleiti tsa alloy tse kopantsoeng ke aluminium, magnesium le silumin (Al-Mg-Si). Li-PCB tsa Aluminium li fana ka mokelikeli o babatsehang oa motlakase, bokhoni bo botle ba mocheso le ts'ebetso e phahameng ea mochine, 'me li fapane le li-PCB tse ling ka litsela tse ngata tsa bohlokoa.

Aluminium PCB Layers

 

MOTHEO LERA

Lera lena le na le substrate ea aluminium alloy. Tšebeliso ea aluminium e etsa hore mofuta ona oa PCB e be khetho e babatsehang bakeng sa thekenoloji ea ka-hole, e tla tšohloa hamorao.

TS'OANELO TSA MOFUTA

Lera lena ke karolo ea bohlokoa haholo ea PCB. E na le polima ea ceramic e nang le thepa e ntle ea viscoelastic, khanyetso e kholo ea mocheso ebile e sireletsa PCB khahlanong le khatello ea mochini le mocheso.

TS'ELISO LEBAKA

Lera la potoloho le na le foil ea koporo e boletsoeng pejana. Ka kakaretso, baetsi ba PCB ba sebelisa lifolakha tsa koporo ho tloha ho li-ounces tse le 'ngoe ho isa ho tse 10.

MOHLOMI DIELECTRIC

Lera la dielectric la ho kenya mocheso le monya mocheso ha nako e ntse e phalla ka har'a lipotoloho. Sena se fetisetsoa lera la aluminium, moo mocheso o qhalakantsoeng.

Ho finyella khanya e phahameng ka ho fetisisa e ka khonehang ho fella ka mocheso o eketsehileng. Li-PCB tse nang le khanyetso e ntlafalitsoeng ea mocheso li eketsa bophelo ba sehlahisoa sa hau se felileng. Moetsi ea tšoanelehang o tla u fa tšireletso e phahameng, ho fokotsa mocheso le ho tšepahala ha karolo. Ho YMS PCB, re itšoarella ka litekanyetso le boleng bo ikhethang boo merero ea hau e e hlokang.
