I. Izinhlobo zephrinta ye-stencil
Iphrinta yezandla iwuhlelo lokuphrinta olulula nolushibhe kakhulu.Ukubekwa nokususwa kwe-PCB kwenziwa ngesandla, i-squeegee ingasetshenziswa ngesandla noma ixhunywe emshinini, futhi isenzo sokunyathelisa senziwa ngesandla.I-PCB ne-steel plate parallelism alignment noma unqenqema lwebhodi ukuqinisekisa ukuthi isikhundla sincike kumakhono omqhubi, ngakho-ke i-PCB ngayinye ephrintiwe, imingcele yokuphrinta izodinga ukulungiswa futhi ishintshwe.
2. Umshini wokuphrinta ozishintshayo ozishintshayo
Imishini yokunyathelisa eyi-Semi-automatic njengamanje iyimishini yokunyathelisa esetshenziswa kakhulu kunazo zonke, empeleni ifana kakhulu nemishini yokunyathelisa eyenziwa ngesandla, ukubekwa nokususwa kwama-PCB kusathembele ekusebenzeni okwenziwa ngesandla, umehluko omkhulu ngomshini wezandla ukuthuthukiswa kwekhanda lokunyathelisa. ingakwazi ukulawula kangcono isivinini sokunyathelisa, ingcindezi ye-squeegee, i-angle ye-squeegee, ibanga lokuphrinta kanye nephimbo elingaxhunywanga, izimbobo zamathuluzi noma imiphetho ye-PCB zisasetshenziselwa ukuma, kuyilapho uhlelo lwepuleti lensimbi ukusiza abasebenzi Ukuqedwa kahle kwe-PCB kanye nokulungiswa kwe-steel plate parallelism. .
3. Umshini wokunyathelisa ozenzakalelayo ngokugcwele
I-solder paste iphrintiwe kuma-pads wezingxenye ebhodini lesisekelo, kodwa namuhla ubukhulu bezingxenye ezifakwe phezulu buba buncane futhi bucwebe, ngakho-ke ukuklanywa kwebhodi lesisekelo sesifunda kuncane ngokuhambisanayo futhi kucolekile.Ngakho-ke, ukunemba nokusebenza kahle kokuphrinta kwe-solder paste kufanele kuthuthukiswe kakhulu.Namuhla, iningi labakhiqizi bomkhiqizo we-elekthronikhi basebenzisa imishini yokuphrinta yokunamathisela ye-solder ezenzakalelayo noma ezenzakalelayo ngokugcwele ukukhiqiza imikhiqizo ye-SMT, futhi ukubekwa kwe-PCB kwenziwa ngebhande eliphethe unqenqema lokuhambisa, elinemingcele yenqubo efana nesivinini se-squeegee, ukucindezela kwe-squeegee, ubude bokuphrinta, kanye i-non-contact pitch konke kuyahleleka.
Ukuma kwe-PCB kwenziwa ngokusebenzisa izimbobo zokubeka noma imiphetho yebhodi, futhi ezinye izinto zokusebenza zingasebenzisa ngisho nezinhlelo zombono ukuze ziqondanise i-PCB ne-steel plate parallel komunye nomunye, okuqeda amaphutha abangelwa ukuma konqenqema lapho kusetshenziswa izinhlelo zombono ezinjalo, futhi kwenza ukuma kube lula, ngokuqinisekiswa kokuma kwesandla esikhundleni samasistimu okubona.Amaphrinta amasha we-solder paste afakwe amalensi evidiyo ukuze aqaphe isimo sokuphrinta futhi enze izilungiso noma kunini.
II.Ukugcinwa kwephrinta ye-stencil
Susa i-squeegee, sebenzisa iphepha elikhethekile lokusula elifakwe ku-ethanol ye-anhydrous, sula i-squeegee ihlanzekile, bese ifakwa ekhanda lokunyathelisa noma itholwe kukhabhinethi yamathuluzi.
Hlanza i-stencil, kunezindlela ezimbili.
Indlela 1: Ukuhlanza umshini wokuwasha.Ukugeza imishini ngesifanekiso, umphumela wokuhlanza ungcono kakhulu.
Indlela 2:Ukuhlanza mathupha.
Sebenzisa iphepha lokusula elikhethekile ukuze usebenzise i-anhydrous ethanol, i-solder paste izosulwa, uma ukuvinjelwa kwembobo yokuvuza, etholakala nge-toothbrush ethambile, ungagwazi ngenaliti eqinile.
Sebenzisa isibhamu somoya esicindezelwe ukuvuthela insalela emgodini ovuzayo wesifanekiso uhlanzeke.
Faka isifanekiso emshinini wokulayisha wokunamathisela, ngaphandle kwalokho sithole ekhabetheni lamathuluzi.
