Izinyathelo Zokuqaphela Ngokuphrinta Ibhodi Le-PCB: Umhlahlandlela We-Solder Mask Ink

Yethula:

Lapho kukhiqizwa amabhodi esekethe aphrintiwe (ama-PCB), ukusebenzisa izinto ezifanele kanye namasu kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokwethembeka. Isici esibalulekile sokukhiqizwa kwe-PCB ukusetshenziswa kweyinki yemaski ye-solder, esiza ukuvikela iminonjana yethusi nokuvimbela amabhuloho e-solder ngesikhathi sokuhlanganiswa. Nokho, ukuze uthole imiphumela ephelele yokunyathelisa yebhodi le-PCB, kufanele kulandelwe izinyathelo ezithile zokuqapha.Kulokhu okuthunyelwe kwebhulogi, sizoxoxa ngezinyathelo zokuphepha ezidingekayo okufanele zicatshangelwe lapho uphatha oyinki bemaski be-solder, sichaza izici ezibalulekile zokugcina izinga eliphezulu nokusebenza.

1. Khetha inki yemaski ye-solder efanelekile:

Ukukhetha inki yemaski ye-solder elungile kubalulekile ekufinyeleleni isiphetho esithembekile nokungaguquguquki. Ngokufanelekile, uyinki okhethiwe kufanele unikeze ukunamathela okuhle kakhulu endaweni ye-PCB, ube nokumelana nokushisa okuphezulu, futhi ube nezakhiwo ezinhle zokuvala ugesi. Izinto ezifana ne-substrate yebhodi lesifunda, izidingo zenqubo yokukhiqiza, nezici ze-PCB ezifiselekayo kufanele zicatshangelwe lapho kwenziwa lesi sinqumo esibucayi.

2. Ukugcinwa nokuphatha ngendlela efanele:

Uma uyinki yemaski ye-solder isitholiwe, ukugcinwa okufanele nokuphatha kubalulekile ekugcineni ukusebenza kwayo. Kutuswa ukuthi ugcine uyinki endaweni epholile, eyomile ekude nelanga eliqondile kanye noshintsho olukhulu lokushisa. Qinisekisa ukuthi isiqukathi sivaliwe uma singasetshenziswa ukugwema ukomiswa noma ukungcoliswa kukayinki. Izinyathelo ezifanele zokubamba, njengokugqoka amagilavu ​​nokuthatha izinyathelo zokuvikela ukuchitheka nokuthinta isikhumba, kufanele zisetshenziswe ukuze kuqinisekiswe ukuphepha komuntu siqu nokugcina ubuqotho bukayinki.

3. Ukwelashwa kwendawo:

Ukufeza isicelo esiphelele seyinki yemaski ye-solder kudinga ukulungiswa okuphelele kwendawo. Ngaphambi kokufaka uyinki, indawo ye-PCB kufanele ihlanzwe ukuze kukhishwe noma yikuphi ukungcola okunjengothuli, amafutha, noma izigxivizo zeminwe. Izindlela zokuhlanza ezifanele, ezinjengokusebenzisa izihlanzi ezikhethekile ze-PCB nezindwangu ezingenalo i-lint, kufanele zisetshenziswe ukuze kuqinisekiswe indawo ehlanzekile. Noma yiziphi izinhlayiya ezisele noma ukungcola okusele ebhodini kuzothinta kabi ukunamathela nokusebenza kukonke kweyinki.

4. Ukucatshangelwa kwezici zemvelo:

Izimo zemvelo zidlala indima ebalulekile ekuqinisekiseni ukusetshenziswa kweyinki yemaski ye-solder efanelekile. Izinto ezifana nezinga lokushisa nomswakama kufanele ziqashwe eduze futhi zilawulwe ngaphakathi kwebanga elishiwo umkhiqizi weyinki. Izimo zemvelo ezeqisayo noma eziguquguqukayo zingathinta i-viscosity kayinki, isikhathi sokumisa kanye nezakhiwo zokunamathela, okuholela emiphumeleni yokuphrinta engemihle. Ukulinganiswa okuvamile kwemishini yokulawula imvelo kuyanconywa ukuze kugcinwe izimo ezidingekayo kuyo yonke inqubo yokukhiqiza ye-PCB.

5. Ubuchwepheshe bokusebenza:

Ukusetshenziswa kahle kweyinki yemaski ye-solder kubalulekile ekuzuzeni imiphumela oyifunayo. Cabangela ukusebenzisa okokusebenza okuzenzakalelayo njengemishini yokuphrinta isikrini noma izindlela ze-inkjet ukuze uqinisekise ukutholakala okunembayo nokungaguquguquki. Qaphela ukusebenzisa inani elifanele likayinki ukuze uqinisekise ukumbozwa okuphelele, kodwa hhayi ukujiya kakhulu. Ukulawula kahle ukugeleza kukayinki, ukushuba kwesikrini, nokucindezela kwe-squeegee (esimeni sokuphrinta isikrini) kuzosiza ukufeza ukubhaliswa okunembile futhi kuvimbele amaphutha afana namaphinifa, ukopha, noma ukuvala ibhuloho.

6. Ukwelapha nokomisa:

Isinyathelo sokugcina senqubo yokufakwa kweyinki yemaski ye-solder ukuphulukisa nokomisa. Landela izinkombandlela zomkhiqizi ngezinga lokushisa elifanele kanye nobude besikhathi obudingekayo ukuze uyinki ululaphe ngempumelelo. Gwema ukushisisa ngokushesha noma ukupholisa ngoba lokhu kungase kubangele ukucindezelwa noma ukuncipha kongqimba lukayinki olulashiwe. Qinisekisa isikhathi esanele sokumisa ngaphambi kokuqhubeka nezinqubo zokukhiqiza ezilandelayo ezifana nokubeka ingxenye noma ukusoda. Ukugcina ukungaguquguquki ekwelapheni nasekumisweni kwemingcele kubalulekile ekutholeni imaski ye-solder efanayo futhi eqinile.

Ekuphetheni:

Lapho usebenzisana noyinki wamaski we-solder, ukuthatha izinyathelo zokuphepha ezidingekayo phakathi nenqubo yokuphrinta yebhodi le-PCB kubalulekile ukuze kuqinisekiswe imiphumela ephezulu, ethembekile nehlala isikhathi eside. Ngokukhetha ngokucophelela inki ye-mask ye-solder efanele, ukuzijwayeza ukugcinwa nokuphatha okufanele, ukulungisa kahle indawo engaphezulu, ukulawula izici zemvelo, ukusebenzisa amasu okufaka isicelo anembile, nokulandela izinqubo ezinconyiwe zokuphulukisa nokomisa, abakhiqizi bangakhiqiza ama-PCB angenasici ngenkathi begcina inqubo yokukhiqiza ukungaguquguquki. Ukunamathela kulezi zinyathelo zokuphepha kungathuthukisa kakhulu amandla embonini yokukhiqiza ye-PCB, kunciphise amaphutha, futhi kwandise ukwaneliseka kwamakhasimende.
