Litlhokomelo bakeng sa Khatiso ea Boto ea PCB: Tataiso ea Solder Mask Ink

Tsebisa:

Ha ho etsoa liboto tsa potoloho tse hatisitsoeng (PCBs), ho sebelisa lisebelisoa le mekhoa e nepahetseng ho bohlokoa ho netefatsa ts'ebetso e nepahetseng le ts'epo. Karolo ea bohlokoa ea tlhahiso ea PCB ke ts'ebeliso ea enke ea mask ea solder, e thusang ho sireletsa mesaletsa ea koporo le ho thibela marokho a solder nakong ea kopano. Leha ho le joalo, ho fumana liphetho tse phethahetseng tsa khatiso tsa boto ea PCB, mehato e itseng ea tšireletso e tlameha ho lateloa.Ka poso ena ea blog, re tla tšohla litemoso tse hlokahalang tse lokelang ho nahanoa ha u sebetsana le li-inks tsa mask a solder, ho hlalosa lintlha tsa bohlokoa ho boloka boleng bo phahameng le ts'ebetso.

1. Khetha enke e loketseng ea maske ea solder:

Ho khetha enke e nepahetseng ea mask ea solder ho bohlokoa ho fihlela pheletso e tšepahalang le e tsitsitseng. Ha e le hantle, enke e khethiloeng e lokela ho fana ka ho khomarela hantle holimo ho PCB, ho ba le mocheso o phahameng oa mocheso, le ho ba le thepa e ntle ea ho kenya motlakase. Lintlha tse kang substrate ea boto ea potoloho, litlhoko tsa ts'ebetso ea tlhahiso, le litšobotsi tse lakatsehang tsa PCB li lokela ho nahanoa ha ho etsoa qeto ena ea bohlokoa.

2. Ho boloka le ho tšoara ka nepo:

Hang ha enke ea mask ea solder e fumaneha, polokelo e nepahetseng le ho e tšoara li bohlokoa ho boloka ts'ebetso ea eona. Ho khothalletsoa ho boloka enke sebakeng se phodileng, se omileng hole le khanya ea letsatsi le liphetoho tse feteletseng tsa mocheso. Etsa bonnete ba hore setshelo se tiisitsoe ha se sa sebelisoe ho qoba ho omella kapa ho silafala ha enke. Mehato e nepahetseng ea ho sebetsana, joalo ka ho roala liatlana le ho nka mehato ea ho thibela ho qhalana le ho ama letlalo, e lokela ho sebelisoa ho netefatsa polokeho ea botho le ho boloka botšepehi ba enke.

3. Phekolo ea holim'a metsi:

Ho fihlella ts'ebeliso e phethahetseng ea enke ea mask ea solder ho hloka boitokiso bo phethahetseng ba bokaholimo. Pele o kenya enke, bokaholimo ba PCB bo tlameha ho hloekisoa ho tlosa litšila leha e le life tse kang lerōle, mafura kapa menoana. Mekhoa e nepahetseng ea ho hloekisa, e kang ho sebelisa lihloeki tse khethehileng tsa PCB le masela a se nang lint, e tlameha ho sebelisoa ho netefatsa hore sebaka se hloekile. Likarolo leha e le life tse setseng kapa litšila tse setseng holim'a boto li tla ama hampe ho khomarela le ho sebetsa ka kakaretso ha enke.

4. Ho nahanoa ka lintlha tsa tikoloho:

Maemo a tikoloho a phetha karolo ea bohlokoa ho netefatsa ts'ebeliso e nepahetseng ea enke ea mask ea solder. Lintlha tse kang mocheso le mongobo li lokela ho hlokomeloa le ho laoloa ka har'a mefuta e boletsoeng ke moetsi oa enke. Maemo a tikoloho a feteletseng kapa a feto-fetohang a ka ama viscosity ea enke, nako ea ho omisa le thepa ea ho khomarela, ho baka liphello tse mpe tsa khatiso. Tekanyetso ea kamehla ea lisebelisoa tsa taolo ea tikoloho e khothaletsoa ho boloka maemo a hlokahalang nakong eohle ea ts'ebetso ea tlhahiso ea PCB.

5. Theknoloji ea ts'ebeliso:

Tšebeliso e nepahetseng ea enke ea mask ea solder e bohlokoa ho fihlela sephetho se lakatsehang. Nahana ka ho sebelisa lisebelisoa tse ikemetseng joalo ka mechini ea khatiso ea skrineng kapa mekhoa ea inkjet ho netefatsa tšireletso e nepahetseng le e ts'oanang. Ela hloko ho sebelisa palo e nepahetseng ea enke ho netefatsa tšireletso e felletseng, empa eseng botenya bo bongata haholo. Taolo e nepahetseng ea ho phalla ha enke, tsitsipano ea skrine, le khatello ea squeegee (tabeng ea khatiso ea skrine) e tla thusa ho finyella ngoliso e nepahetseng le ho thibela likoli tse kang li-pinholes, ho tsoa mali, kapa ho koala borokho.

6. Ho phekola le ho omisa:

Mohato oa ho qetela ts'ebetsong ea kopo ea enke ea mask ea solder ke ho folisa le ho omisa. Latela litataiso tsa moetsi bakeng sa mocheso o nepahetseng le nako e hlokahalang hore enke e phekolehe hantle. Qoba ho futhumatsa kapa ho tsidifala ka potlako kaha sena se ka baka kgatello kapa delamination ya lera le phekotsweng la enke. Etsa bonnete ba hore ho na le nako e lekaneng ea ho omisa pele u tsoela pele ka mekhoa e latelang ea tlhahiso e kang ho beha likarolo kapa ho kopanya. Ho boloka botsitso ba ho folisa le ho omisa ho bohlokoa bakeng sa ho fumana mask a solder a junifomo le a tšoarellang.

Ha re phethela:

Ha u sebetsana le li-inks tsa mask a solder, ho nka mehato e hlokahalang nakong ea ts'ebetso ea khatiso ea boto ea PCB ho bohlokoa ho netefatsa liphetho tsa boleng bo holimo, tse tšepahalang le tse tšoarellang nako e telele. Ka ho khetha ka hloko enke e nepahetseng ea mask ea solder, ho itloaetsa ho boloka le ho sebetsana hantle, ho lokisa ka ho lekaneng holim'a metsi, ho laola maemo a tikoloho, ho sebelisa mekhoa e nepahetseng ea kopo, le ho latela mekhoa e khothalletsoang ea ho folisa le ho omisa, bahlahisi ba ka hlahisa li-PCB tse se nang sekoli ha ba ntse ba boloka ts'ebetso ea tlhahiso e tsitsitseng. Ho latela litemoso tsena ho ka ntlafatsa haholo bokhoni ba indasteri ea tlhahiso ea PCB, ho fokotsa likoli, le ho eketsa khotsofalo ea bareki.
