5 Mefuta e Meholo ea PCB Solder Mask

Maske ea solder , karolo ea bohlokoa lefatšeng la tlhahiso ea lisebelisoa tsa elektroniki, e bapala karolo ea bohlokoa ho sireletseng liboto tsa potoloho tse hatisitsoeng (li-PCB) linthong tsa tikoloho, ho thibela marokho a solder, le ho netefatsa botšepehi ba lisebelisoa tsa elektroniki ka kakaretso. Tataisong ena e felletseng, re tla teba ka botebo mefuta e fapaneng ea maske ea solder, thepa ea eona e ikhethang, le lits'ebetso tse ikhethileng tseo li li loketseng hantle. Ka ho tsepamisa maikutlo ho maske ea solder e nang le epoxy liquid photoimageable (LPC/LPI), epoxy powder coating, maske ea solder e thehiloeng ho silicone le urethane acrylate, maske ea solder e tenyetsehang, le maske ea solder e thibelang malakabe, re ikemiselitse ho fana ka kutloisiso e qaqileng ea likhetho tse fumanehang ho baqapi le bahlahisi ba PCB.

Limaske tsa Epoxy Liquid Photoimageable Solder (LPC/LPI)

Epoxy Liquid Photoimageable Solder Masks, eo ka tloaelo e tsejoang ka hore ke LPC kapa LPI solder masks, e emela khetho e atileng ka ho fetesisa le e theko e boima ka har'a sebaka sa li-solder mask formulations. Ba natefeloa ke tšebeliso e pharalletseng indastering ea lisebelisoa tsa elektroniki ka lebaka la ho ikamahanya le maemo le ho ts'epahala ha bona.

Li-mask tsa solder tsa LPC/LPI li khetholloa ka mokhoa oa tsona o ikhethang oa ho folisa, o kenyelletsang ho pepesetsoa khanya ea UV. Thepa ena e lumella bahlahisi ho sebelisa taolo e nepahetseng mabapi le ts'ebetso ea ho phekola, ho etsa limaske tsa solder LPC/LPI khetho e ratoang bakeng sa lits'ebetso tse fapaneng. Ntho e 'ngoe e hlokomelehang ea limaske tsa solder LPC/LPI ke mefuta e fapaneng ea mebala eo li fumanehang ka eona. Ho feto-fetoha hona ha khetho ea mebala ho thusa ho nahana ka botle moetsong oa PCB, ho lumella ho itlhophisa ho tsamaellanang le likarolo tse bonoang tsa sehlahisoa sa ho qetela sa elektroniki.

Mabapi le lits'ebetso, limaske tse rekisoang tsa LPC/LPI ke khetho ea mantlha bakeng sa maemo a mangata indastering ea lisebelisoa tsa elektroniki. Tšebeliso e ntle ea litšenyehelo le boiketlo ba tšebeliso ea tsona li etsa hore li tšoanelehe bakeng sa lisebelisoa tsa elektroniki tsa bareki, ho kenyeletsoa li-smartphone le lilaptop, moo ts'ireletso ea PCB e leng bohlokoa. Ho feta moo, mechini ea indasteri le litsamaiso tsa othomathike le tsona li rua molemo ho ts'epahalo ea limaske tsa solder LPC/LPI. Baetsi ba lisebelisoa tsa mehala ba ananela ho feto-fetoha ha limaske tse rekisoang tsa LPC/LPI, kaha li khona ho sebetsana le litlhoko tse fapaneng tsa PCB, ho netefatsa ho tšoarella le ho sebetsa ha likarolo tsa bohlokoa.

Epoxy Powder Coating

Li-mask tsa solder tsa epoxy phofo li fana ka mokhoa o mong ho balekane ba bona ba metsi, leha ho na le mefokolo e itseng mabapi le ts'ebetso. Tšobotsi e 'ngoe e ikhethang ea limaske tsa epoxy powder coating solder ke mokhoa oa tsona oa kopo. Ho fapana le limaske tsa solder tsa metsi, limaske tsa epoxy powder coating solder li sebelisoa ka mokhoa o omileng oa phofo ebe oa phekoloa. Phapang ena ea mokhoa oa ts'ebeliso e susumetsa ho tšoaneleha ha tsona bakeng sa lits'ebetso tse ikhethileng.

Li-mask tsa solder tsa epoxy phofo li fumana sebaka sa tsona haholo-holo sebakeng sa lihlahisoa tsa bareki. Hangata li sebelisoa lisebelisoa tsa ka tlung, lisebelisoa tsa papali, le lintho tsa ho bapala, moo ho nahanela litšenyehelo ho bapalang karolo ea bohlokoa. Theko e tlase ea li-epoxy powder coating solder masks li etsa hore e be khetho e ntle ea moruo bakeng sa thepa ena ea bareki, ho netefatsa tšireletso e lekaneng ea PCB ha e ntse e boloka ho khoneha.

Li-mask tsa Solder tse thehiloeng ho Silicone le Urethane Acrylate

Li-mask tse entsoeng ka silicone le urethane acrylate solder li hlahella ka mokhoa o tsotehang oa ho hanyetsa mocheso o phahameng le ho fetoha habonolo. Li-mask tsena tsa solder li etselitsoe ho fihlela litlhoko tse khethehileng tsa PCB, haholo-holo maemong ao maemo a feteletseng a tšoenyang.

E 'ngoe ea litšobotsi tse ka sehloohong tsa li-silicone-based le urethane acrylate solder masks ke bokhoni ba bona ba ho mamella mocheso o phahameng. Thepa ena e bohlokoa bakeng sa lits'ebetso moo ho felloang ke mocheso ho leng bohlokoa, joalo ka indastering ea lifofane le tsa likoloi. Li-mask tsena tsa solder li netefatsa hore li-PCB li ka sebetsa ka mokhoa o ts'epahalang le ha li pepesehetse mocheso o feteletseng, ho li etsa khetho e ratoang bakeng sa likarolo tsa bohlokoa makaleng ana.

Ntho e 'ngoe e hlokomelehang ea li-silicone-based le urethane acrylate solder masks ke ho fetoha ha tsona. Li-PCB tse ka 'nang tsa e-ba le khatello ea maikutlo kapa ea mochine li itšetlehile ka limaske tsena tsa solder ho boloka botšepehi ba bona ba sebopeho. Ho feto-fetoha hona ho tiisa hore mask a solder ha a fetohe brittle ka nako, e leng se tlatsetsang ho tšoarella nako e telele ha li-circuits tse feto-fetohang.

Li-mask tse bonolo tsa Solder

Li-mask tse bonolo tsa solder li etselitsoe ho khotsofatsa litlhoko tse ikhethang tsa li-circuits tse feto-fetohang, tse fapaneng haholo le li-PCB tse thata. Ho fapana le liboto tse thata, lipotoloho tse feto-fetohang li hloka mask a solder a ka bolokang maemo le kamora ts'ebetso ea ho folisa.

Tšobotsi e ikhethang ea limaske tsa solder tse feto-fetohang ke bokhoni ba bona ba ho boloka maemo a bonolo. Thepa ena e bohlokoa bakeng sa ho netefatsa hore mask a solder ha a qhekelle ha a le tlas'a khatello ea maikutlo kapa ea mochini, ketsahalo e tloaelehileng lipotolohong tse tenyetsehang. Joalo ka ha lebitso le fana ka maikutlo, limaske tse tenyetsehang tsa solder li etselitsoe lits'ebetso tsena ka ho khetheha.

Li-circuits tse feto-fetohang li atile liindastering tse fapaneng, ho kenyeletsoa theknoloji e aparoang le lisebelisoa tsa bongaka. Likopong tse joalo, bokhoni ba ho boloka ho feto-fetoha ha maemo ke ba bohlokoa, kaha bo tiisa ts'ebetso le nako e telele ea likarolo tsa elektronike ka har'a lisebelisoa tsena.

Li-Mask tsa Solder tse Lekang Lelakabe

Li-mask tsa solder tse thibelang malakabe li entsoe ho fihlela litekanyetso tse thata tsa ho tuka, tse etelletsang pele ho latela melao ea polokeho. Hangata li sebelisoa liindastering le lihlahisoa moo polokeho ea mollo e leng ntho e amehang haholo.

Tšobotsi e ka sehloohong ea limaske tsa solder tse thibelang mollo ke ho lumellana ha tsona le litekanyetso tse khethehileng tsa indasteri. Ho latela melao ena ho netefatsa hore lihlahisoa tse kenyelletsang limaske tsena tsa solder li fihlela litlhoko tse hlokahalang tsa polokeho. Ka lebaka leo, limaske tsa solder tse thibelang malakabe ke khetho e ntle bakeng sa liindasteri le lihlahisoa moo tšireletso ea mollo e ke keng ea senyeha.

Thepa ea bareki, joalo ka lisebelisoa tsa lapeng le lintho tsa ho bapala tsa elektroniki, li rua molemo haholo ho limaske tsa solder tse thibelang mollo. Ka ho fokotsa kotsi ea likotsi tsa mollo, limaske tsena tsa solder li ntlafatsa tšireletseho ea lihlahisoa tse joalo, li fana ka khotso ea kelello ho bareki le bahlahisi ka ho tšoanang.

Ha projeke e fetoha ho tloha lipatlisisong ho ea ho RFQ, hlahloba bakhanni ba litšenyehelo tsa khotheishene ea PCB le tlhahiso ea boto e boima ea koporo e le hore litlhoko tsa thepa, ts'ebetso le tlhahlobo li lule li tsamaellana.
