Imboni yebhodi lesifunda le-PCB ibilokhu inezidingo eziqinile zekhwalithi yenqubo yokukhiqiza.Phakathi kwazo, ububomvu bebhodi lesifunda le-PCB elibangelwa ukuphrinta kwesikrini semaski solder kuyinto evamile engathandeki.Akuthinti nje kuphela ubuhle bangaphandle be-PCB, kodwa futhi kuthinta ibhodi lesifunda.Kukhona futhi ubungozi bekhwalithi ekusebenzeni.Lesi sihloko - i-pcb Equipment Network izoholela ekubeni ube nokuqonda okujulile kwezimbangela nezisombululo zokubomvu kwebhodi le-PCB okubangelwa ukuphrinta kwesikrini semaski solder ebhodini lesifunda le-PCB.
1. Isizathu esenza PCB wesifunda ibhodi solder imaski ukuphrinta isikrini kubangela ububomvu ebusweni ebhodini
1. Ugqinsi lwesendlalelo semaski ye-solder abukho ezingeni elijwayelekile noma kukhona amabhamuza ayizinsalela:
Isendlalelo semaski ye-solder sibhekisela kungqimba lwesendlalelo sokuzivikela esimbozwe ebhodini lesifunda ngemva kokunyathelisa ngesikrini semaski se-inki solder ukuvimbela isifunda ukuthi singathonywa yizici ezifana nemvelo yangaphandle;lapho ubukhulu bongqimba lwemaski ye-solder bungekho ezingeni elijwayelekile noma kukhona amabhamuza asele, kuyadingeka Phakathi nalesi sigaba, ukusabela kwe-oxidation kujwayele ukwenzeka lapho kuhlangabezana nezimo zokushisa okuphezulu, okuholela ekubeni bubomvu phezu kwebhodi, okuholela ekuhluphekeni. Ikhwalithi ye-PCB.
- Ikhwalithi kayinki ayikho ezingeni:
Uma uyinki ngokwawo osetshenziselwa ukuphrinta isikrini semaski ye-solder unezinkinga zekhwalithi, njengoyinki ophelelwe yisikhathi kanye nokwenyuka kwe-viscosity kayinki, kungase kubangele umphumela wokuvikela we-solder mask ungqimba wehluleke, noma ungase ungasivali ngokuphelele isifunda, ushiye izikhala nokunye. izintuba zekhwalithi, ekugcineni okuholela ezenzakalweni ezingathandeki njengokubomvu endaweni yebhodi kungase kubangele izingozi ezingaziwa kanye nomthelela ekusebenzeni kwayo nekhwalithi.
3. I-Flux neyinki yemaski ye-solder ayifani:
Ikhwalithi embi yamabhodi esekethe e-PCB ephrintiwe ivamise ukuvela ekuxhumaneni kwezinqubo ezihlobene noma eziseduze.Isibonelo, i-flux ne-solder resist inki ayifani noma ayihambisani, okungase futhi kuholele ezingxabano, izinguquko zempahla, njll., okuholela ekubomvu kwebhodi lebhodi.
2. Amasu okuxazulula i-PCB circuit board solder mask screen printing okubangela ububomvu endaweni yebhodi
1.PCB ibhodi lesifunda sebhodi lemaski yesikrini sokuphrinta-ngaphambi kokukhiqizwa kokucaciswa kokucaciswa:
Ukukhethwa kweyinki yemaski ye-Solder, ukuguqulwa kwe-viscosity ye-inki, impilo yeshalofu ye-inki, i-flux nezinye izinto ezisetshenziswayo ezihlobene nokuphathwa okujwayelekile kanye namazinga okusebenza, ukwakha imingcele nezinyathelo zokugwema izingozi zokukhubazeka kwe-PCB ezibangelwa izinto zokusetshenziswa.
2.PCB ibhodi lesifunda solder imaski isikrini ukuphrinta-in-production inqubo inqubo:
Umshini wokunyathelisa isikrini sebhodi lesifunda se-PCB uqhubeka ufingqa futhi ulungisa amaphutha futhi wenze ukumiswa kwepharamitha okujwayelekile okusekelwe ezidingweni zokuphrinta ukuze kuqinisekiswe izilinganiso zesayensi nezinengqondo, ngaleyo ndlela kuqinisekiswe ikhwalithi yokukhiqiza eqhubekayo nezinzile.
3.PCB ibhodi lesifunda solder imaski isikrini sokuphrinta-post-production ikhwalithi yokuhlolwa:
Thuthukisa izinyathelo zenqubo yokuhlola ikhwalithi enengqondo ukuze uqinisekise ukutholwa kwezinkinga ngesikhathi ukuze ugweme ukwanda kokulahlekelwa futhi unciphise umthelela ekusebenzeni kahle kokukhiqiza.
4.PCB ibhodi lesifunda solder imaski isikrini sokuphrinta-ukuqeqeshwa kokukhiqiza isisebenzi:
Ukuthuthukisa ikhono labasebenzi lokuhlonza, ukuhlonza, ukuhlaziya nokuxazulula izinkinga zekhwalithi yenqubo, ukuthuthukisa amakhono ochwepheshe nokuqonda izimiso zezinkinga ezimbi, ukuhlola nokuqeqesha okuvamile, nokwenza izinqubo ezijwayelekile zokusebenza ukuze abasebenzi bakwazi ukusebenza kahle nangokunembile, futhi baphendule. nokuxazulula izinkinga ezahlukene ngesikhathi.isimo esiphuthumayo.
3. Ukuphrinta kwesikrini semaski se-PCB sebhodi ye-solder kubangela ukuthi indawo yebhodi ibe bomvu.Okufanele ukwenze ngamafuphi
Inkinga ye-PCB circuit board solder mask screen printing board redness iyinkinga evamile enqubweni yokukhiqiza, kodwa akuyona inkinga eyinkimbinkimbi.Imvamisa iba mncane futhi isesigabeni sokuqala, futhi kulula ukwenzeka ezimbonini ezingenamsebenzi nezijwayelekile.Ukuze kuxazululwe le nkinga, kufanele kugxilwe izinqubo zokusebenza ezisezingeni eliphakeme nezijwayelekile, ukukhetha okufanele umshini wokunyathelisa we-PCB webhodi le-solder imaski yesikrini kanye nama-opharetha ochwepheshe ukuze kugwenywe ukwenzeka kwamaphutha anjalo asezingeni eliphansi, okuzothinta ikhwalithi yenkampani kanye nokuphelele. izinzuzo.
