The Gold Plating Process ka PCBs

Ts'ebetso ea ho roala khauta ho Li-Printed Circuit Boards (PCBs) ke karolo ea bohlokoa e fanang ka liboto tsena ka thepa ea tsona e ikhethang. Ho utloisisa ts'ebetso ena ho fana ka leseli la hore na ke hobane'ng ha li-PCB tse pentiloeng ka khauta li le bohlokoa haholo ho lisebelisoa tsa elektroniki.

1. Ho Lokisetsa Sefahleho

Ho Hloekisa le ho Boreleli: Pele ho pentiloe ka khauta, bokaholimo ba PCB bo tlameha ho hloekisoa hantle le ho boreleli. Litšilafalo leha e le life kapa lintho tse sa tsitsang li ka ama ho khomarela le boleng ba khauta ea khauta.
Micro-etching: Mokhoa oa micro-etching o atisa ho sebelisoa ho etsa hore bokaholimo bo be thata, bo matlafatsa ho khomarela koporo e ka tlaase.

2. Base Layer Plating

Nickel Plating: Maemong a mangata, lera la nickel le qala ho kenngoa ho PCB. Nickel e sebetsa e le tšitiso ea ho thibela khauta hore e se ke ea hasana ka har'a koporo 'me e fana ka bokaholimo ba khauta ho khomarela.
Ho Kopana le Botenya: Lera lena la nickel le tlameha ho tšoana ka botenya 'me le se ke la ba le sekoli ho netefatsa boleng le bophelo bo bolelele ba khauta ea khauta.

3. Khauta Plating

Tokisetso ea Pele ho Plating

Ho Hloekisa Bokaholimo: Mohato oa pele o kenyelletsa ho hloekisoa ka botlalo ha bokaholimo ba PCB ho tlosa litšila life kapa life. Hangata sena se finyelloa ho sebelisoa libate tsa lik'hemik'hale tse tlosang oli, litšila le lihlahisoa tsa oxidation.
Microscopic Surface Etching: Kamora ho hloekisoa, tharollo ea asiti e bonolo hangata e sebelisoa bakeng sa ho koala bokaholimo. Ts'ebetso ena e etsa hore ho be le sebopeho se thata hanyenyane boemong ba microscopic, e thusang ho khomarela likarolo tsa tšepe tse latelang.

Sesebelisoa sa Nickel Underlayer

Electroless Nickel Plating: Pele ho plating ea khauta, lesela la nickel le kenngoa. Hangata sena se etsoa ho sebelisoa mokhoa oa ho roala ka motlakase, oo, ho fapana le electroplating ea setso, ha e hloke motlakase oa motlakase.
Barrier Properties of Nickel: Nickel e sebetsa e le tšitiso ho thibela ho ata ha koporo lera la khauta. Sena se bohlokoa kaha phepelo ea koporo e ka lebisa ho oxidation, ea senya thepa ea motlakase ea PCB.

Ts'ebetso e qaqileng ea Gold Plating

Ho qoelisoa ka Khauta: Thepa ea 'nete ea khauta hangata e etsoa ho sebelisoa mokhoa oa ho qoelisoa. PCB e qoelisoa ka bateng e nang le letsoai la khauta le lik'hemik'hale tse ling. Ka karabelo ea ho falla, lesela le tšesaane la khauta le beoa lera la nickel.
Taolo ea Botenya: Ho laola botenya ba lesela la khauta ho bohlokoa. Bakeng sa lits'ebetso tse ngata, lesela la khauta le bolokoa le le tšesaane, hangata le botenya ba lisenthimithara tse 'maloa feela. Sena se lekane ho fana ka thepa e hlokahalang ea holim'a metsi ntle le ho theko e boima haholo.

Tlhahlobo ea Post-Plating le Taolo ea Boleng

Tekanyo ea Botenya: Kamora ho roala, botenya ba lesela la khauta bo lekanyetsoa ho sebelisoa mekhoa e kang X-ray fluorescence kapa tlhahlobo ea botenya ba coulometric.
Teko ea Adhesion: Ho netefatsa hore lesela la khauta le khomarela nickel hantle, ho etsoa liteko tse fapaneng tsa ho khomarela, joalo ka liteko tsa tepi.
