Kungani i-PCB (ibhodi lesekethe eliphrintiwe) kufanele iphendwe ngezinto zokuhlanganisa ezihambisanayo?Indlela yokudweba ngokunembile futhi ngokushesha ibhodi lesifunda?

I-PCB ibhekisela ebhodini lesifunda eliphrintiwe, elingumhlinzeki woxhumano lukagesi lwezingxenye ze-elekthronikhi.Kuvame kakhulu embonini ye-elekthronikhi, futhi i-conformal coating nayo isetshenziswa kabanzi.Ayikho ingcina ye-PCB emithathu yokuqinisekisa (upende).Eqinisweni, iwukusebenzisa ungqimba lwe-conformal coating ku-PCB.

Izinto zokumboza ezivumelanayo ukuvikela i-PCB ukuthi ilinyazwe izinto zangaphandle futhi kuthuthukiswe impilo yesevisi ye-PCB.Njengoba imikhiqizo ye-elekthronikhi esezingeni eliphezulu inezidingo eziphakeme neziphakeme zekhwalithi ye-PCB, upende wokufakazela ubufakazi obuthathu usetshenziswa kabanzi kumabhodi esekethe.

Izinto ezingadala umonakalo we-PCB:

Umswakama uyisici esivame kakhulu nesilimazayo ku-PCB.Umswakama owedlulele uzokwehlisa kakhulu ukumelana nokufakwa phakathi kwamakhondatha, kusheshise ukubola, kunciphise inani le-Q, kanye namakhondaktha agle.Ngokuvamile kwenzeka ukuthi ingxenye yensimbi ye-PCB inohlaza lwethusi, okubangelwa ukusabela kwamakhemikhali ethusi lensimbi nomhwamuko wamanzi nomoya-mpilo.

Amakhulu ezinto ezingcolisayo ezitholakala ngokungalindelekile emabhodini esekethe anyathelisiwe anamandla afanayo okubhubhisa.Zingaholela emiphumeleni efanayo nokuguguleka komswakama, njengokubola kwe-elekthronikhi, ukugqwala kwama-conductor ngisho nesifunda esifushane.Ukungcola okuvame ukutholakala ohlelweni lukagesi kungase kube izinto zamakhemikhali ezisele ohlelweni.Lezi zinto ezingcolisayo zihlanganisa i-flux, i-solvent release, izinhlayiya zensimbi kanye noyinki wokumaka.

Kukhona namaqembu amakhulu okungcola okudalwa yizandla zabantu, njengamafutha omuntu, izigxivizo zeminwe, izimonyo nezinsalela zokudla.Kukhona nezinto eziningi ezingcolisa umoya endaweni yokusebenza, njengesifutho sikasawoti, isihlabathi, uphethiloli, i-asidi, esinye isitimu esibolayo kanye nesikhunta.

Kungani kufanele ufake iglue yokuqinisekisa (upende) kathathu?

I-PCB ehlanganiswe ngezinto zokumboza ezihambisanayo ayikwazi nje ukuvikela umswakama, uthuli futhi ingangeni manzi, kodwa futhi ibe nezindawo zokumelana nokushaqeka okubandayo nokushisa, ukumelana nokuguga, ukumelana nemisebe, ukumelana nenkungu kasawoti, ukumelana nokugqwala kwe-ozone, ukumelana nokudlidliza, ukuguquguquka okuhle nokunamathela okuqinile.Uma kuthinteka izinto ezimbi zendawo yokusebenza, kunganciphisa noma kuqede ukwehla kokusebenza kokusebenza kwe-elekthronikhi.

Ngenxa yemvelo ehlukene yokusetshenziswa kwemikhiqizo ehlukene yokugcina, izidingo zokusebenza ze-adhesive ezintathu zokuqinisekisa zizogcizelelwa.Imishini yasendlini njengeziqandisi, imishini yokuwasha nezifudumezi zamanzi zinezidingo eziphakeme zokumelana nomswakama, kuyilapho abalandeli bangaphandle namalambu asemgwaqweni badinga ukusebenza kahle kwe-anti fog.

Ungasifaka kanjani isicelo ngokushesha nangempumeleloenamathela conformalku-PCB?

Embonini yokucubungula i-PCB, kunemishini ezenzakalelayo ezinikele ngokuphelele ekuhlanganiseni upende ovikelayo wamabhodi wesekethe -umshini wokuhlanganisa ohambisanayo, owaziwa nangokuthi umshini wokufaka upende wobufakazi abathathu, umshini wokufafaza ngopende wobufakazi abathathu, umshini wokufafaza ngopende wobufakazi abathathu, ukufafaza ngopende wobufakazi abathathu. umshini, njll., ozinikele ekulawuleni uketshezi kanye nokumboza ungqimba lukapende wobufakazi obuthathu ebusweni be-PCB, njengokumboza ungqimba lwe-photoresist ebusweni be-PCB ngokufaka isisu, ngokufafaza noma nge-spin coating.

Umshini wokuhlanganisa ohambisanayo usetshenziselwa ikakhulukazi ukufafaza okunembayo, ukumboza nokuconsa kweglue, upende nolunye uketshezi enqubweni yomkhiqizo ukuya endaweni eqondile yomkhiqizo ngamunye.Ingasetshenziswa ukudweba imigqa, imibuthano noma ama-arcs.

Umshini wokuhlanganisa ovumelanayo umshini wokufafaza oklanyelwe ngokukhethekile ukufafaza ngopende wobufakazi obuthathu.Ngenxa yezinto ezihlukene okufanele zifafazwe kanye noketshezi olufafazayo olusetshenziswayo, ukukhethwa kwengxenye yomshini wokumboza esakhiweni semishini nakho kuhlukile.Umshini wokumboza upende wesithathu usebenzisa uhlelo lwakamuva lokulawula ikhompuyutha, olukwazi ukubona ukuxhumana kwama-eksisi amathathu.Ngesikhathi esifanayo, ifakwe ikhamera yokumisa kanye nesistimu yokulandelela, engakwazi ukulawula ngokunembile indawo yokufafaza.
