Izimboni eziningi ze-elekthronikhi zicabanga ukuthi ukuthenga umshini wokugcwalisa umshini wokuphinda ugeleze omkhudlwana kungahlangabezana nezidingo ezijwayelekile zokusebenza, kodwa ngokuvamile kubiza imali eningi futhi kudela isikhala esithathiwe.Ukugeleza kabusha kwendawo engu-8 kuye kwayi-10 kanye nesivinini sebhande elisheshayo kungase kube isixazululo esingcono kakhulu endaweni yokukhiqiza umthamo ophezulu, kodwa ulwazi lwethu lubonise ukuthi amamodeli amancane, alula, athengeka kakhudlwana 4 kuya ku-6 zone angumthengisi wethu ophezulu A futhi enza umsebenzi oncomekayo. yokuphatha ukukhetha kanye nokuphuma kwendawo, ihlangabezana nezicaciso zokugeleza kabusha zabakhiqizi be-solder, futhi iletha ukusebenza okuthembekile, kokusebenza kwe-premium.Kodwa ungaqiniseka kanjani?Mingaki imikhiqizo engaphathwa yinqubo yokugeleza kabusha kwendawo engu-4, indawo engu-5 noma engu-6?Ezinye izibalo ezilula ezisuselwe kudatha enikezwe i-solder paste nabahlinzeki bemishini bazokunikeza ireferensi enhle kakhulu.
Isikhathi sokushisa sokunamathisela kwe-solder
Into yokuqala okufanele uyicabangele ukwakheka okunconyiwe komkhiqizi wakho wokunamathisela we-solder ekubunjweni kokunamathisela ozokusebenzisa.Abakhiqizi be-solder paste ngokuvamile bahlinzeka ngezikhathi zewindi ezibanzi ngokufanelekile (ngokwesikhathi sokushisa esiphelele) ezigabeni ezihlukahlukene zephrofayili yokugeleza kabusha - imizuzwana engu-120 ukuya kwangu-240 yokushisa ngaphambi kwesikhathi nesikhathi sokucwilisa, kanye namasekhondi angu-60 kuya kwangu-120 ngesikhathi sokugeleza kabusha/isikhathi esingaphezu kwesimo soketshezi.Sithole isilinganiso sesikhathi sokushisa esiphelele samaminithi angu-4 ukuya kwangu-4½ (amasekhondi angu-240-270) ukuba sibe isilinganiso esihle, esilinganiselayo.Kulesi sibalo esilula, sincoma ukuthi ungaziki ukupholisa kwamaphrofayili ashiselwe.Ukupholisa kubalulekile, kodwa ngokuvamile ngeke kuthinte ikhwalithi yokudayiswa ngaphandle kokuthi i-PCB ipholiswe ngokushesha kakhulu.
Ubude behhavini elishisayo
Ukucatshangelwa okulandelayo yisikhathi sokushisa sokugeleza kabusha okuphelele, cishe bonke abakhiqizi be-reflow bazohlinzeka ngobude bokushisa obugelezayo, ngezinye izikhathi obubizwa ngokuthi ubude bomhubhe wokushisa, ekucacisweni kwabo.Kulesi sibalo esilula, sigxila kuphela endaweni yokugeleza kabusha lapho ukushisa kwenzeka khona.
isivinini sebhande
Ekugelezeni kabusha ngakunye okusebenzisayo, hlukanisa ubude bokushisa (ngamayintshi) ngesamba sesikhathi sokushisa esinconyiwe (ngamasekhondi).Bese phindaphinda ngamasekhondi angu-60 ukuze uthole isivinini sebhande ngamayintshi ngomzuzu.Isibonelo, uma isikhathi sakho sokushisa kwe-solder singamasekhondi angu-240-270 futhi ucabangela ukugeleza kabusha kwendawo engu-6 ngomhubhe ongu-80¾ amayintshi, hlukanisa amayintshi angu-80.7 ngo-240 kanye namasekhondi angu-270.Kuphindwe ngamasekhondi angu-60, lokhu kukutshela ukuthi udinga ukusetha isivinini sebhande lokugeleza kabusha phakathi kuka-17.9 amayintshi ngomzuzu no-20.2 amayintshi ngomzuzu.Uma usunqume ijubane lebhande olidingayo lokugeleza kabusha okucabangayo, udinga ukunquma inani eliphakeme lamabhodi ngomzuzu elingacutshungulwa ekugelezeni kabusha ngakunye.
Inombolo enkulu yamapuleti agelezayo ngomzuzu
Uma sicabanga ukuthi ngomthamo omkhulu kufanele ulayishe amabhodi ekupheleni ukuya ekupheleni ku-conveyor ye-oven's reflow, kulula ukubala isivuno esiphezulu.Isibonelo, uma ibhodi lakho lingama-intshi angu-7 ubude futhi ijubane lebhande likahhavini ogeleza kabusha wezindawo ezingu-6 lisukela kumayintshi angu-17.9 ukuya kumayintshi angu-20.2 ngomzuzu, ukuphuma okuphezulu kwalokho kugeleza kabusha amabhodi angu-2.6 kuya kwangu-2.9 ngomzuzu.Okusho ukuthi, amabhodi wesifunda aphezulu naphansi azothengiswa ngemizuzwana engama-20.
Iyiphi i-Reflow Oven elungele Izidingo Zakho
Ngaphezu kwalezi zici ezingenhla, ziningi ezinye izici okufanele zicatshangelwe.Isibonelo, ukukhiqiza okunezinhlangothi ezimbili kungase kudinge ukugeleza kabusha kwezinhlangothi zombili zengxenye efanayo, futhi ukusebenza kokuhlanganisa okwenziwa ngesandla kungase kuthinte ukuthi ungakanani umthamo wokugeleza kabusha odingekayo ngempela.Uma ukuhlanganisa kwakho kwe-SMT kushesha kakhulu, kodwa ezinye izinqubo zikhawulela ukusebenza kwefekthri yakho, khona-ke ukugeleza kabusha okukhulu kakhulu emhlabeni akukusizi kangako.Esinye isici okufanele icatshangelwe yisikhathi sokushintsha usuka komunye umkhiqizo uye komunye.Kuthatha isikhathi esingakanani ukuthi izinga lokushisa lokugeleza kabusha lizinze lapho lishintsha ukusuka ekucushweni okunye ukuya kokunye?Kunezinto eziningi ezahlukene okufanele uzicabangele.
Imboni yaseChengyuan ibigxile ekufakweni kabusha kwe-solder, i-wave soldering, nemishini yokuhlanganisa iminyaka engaphezu kweshumi.Siyakwamukela ukuthintana nonjiniyela base-Chengyuan ukuze bakukhethele i-reflow soldering ekufanele kakhulu.
