Ngemuva kwesikhathi esithile sokusetshenziswa, i-reflow ovenIgumbi liqukethe inani elikhulu lensalela ye-rosin flux odongeni lwangaphakathi lwegumbi lokugeleza kabusha kanye namapayipi wendawo yokupholisa, okuzonciphisa izinga lokushisa lokushisa lokuphinda kufakwe i-solder futhi kuholele kwikhwalithi ephansi yokunamathisela.Ngakho-ke, i-reflow oven room idinga ukudilizwa futhi ihlanzwe futhi ikhuhle njalo.
Ngaphambi kokuhlanza igumbi le-oven reflow, udinga ukulungisa amathuluzi afanele, kufaka phakathi izipani, ama-ejenti okuhlanza, amagilavu enjoloba, ama-spatula, njll.
Izinyathelo zokuhlanza nezindlela
1. Qiniseka ukuthi alikho ibhodi le-PCBA ekamelweni, cisha amandla bese ulinda imizuzu engu-60.
2. Pholisa izinga lokushisa libe ngama-degree angu-50, nqamula isixhumanisi sangaphandle segumbi lokugeleza kabusha, vula injini yegumbi lomoya futhi uvule igumbi.
3. Hlukanisa izingxenye futhi uzihlanze usebenzisa isicoci se-ultrasonic, bese usula futhi uhlanze futhi usebenzisa isifutho singafafaza isicoci sezingxenye ezingahlakaziwe.
Izixwayiso
1. Gxila ekuhlanzeni udonga lwangaphakathi lwegumbi lesithando somlilo kanye nendawo yokupholisa
2. I-Condenser, ithubhu yokutakula, i-reflow soldering ingahlakazwa izingxenye emshinini wokuhlanza we-ultrasonic ukuze uhlanze.
3. Ukuhlanza isithando somlilo kumele kukhethe imikhiqizo engagqwali, ama-ejenti okuhlanza okugqwala azokwakha ukugqwala endaweni yensimbi ngemva kokuhlanza nokulimaza impahla.
4. Ngemva kokuhlanza, vele wome emoyeni ngokuqondile.
5. Ukuhlanza njalo.
Izici zeI-NeoDen IN12C Reflow Oven
1. Umklamo oyingqayizivele wemodyuli yokushisa unezici zokunemba kokulawula ukushisa okuphezulu, ukusatshalaliswa kokushisa okufanayo endaweni yesinxephezelo esishisayo, ukusebenza kahle kwesinxephezelo sokushisa okuphezulu kanye nokusetshenziswa kwamandla aphansi.
2. I-hot air convection, ukusebenza kahle kwe-soldering.
3. Amafayela asebenzayo angama-40 angagcinwa ukuze alayishwe kalula phakathi nenqubo yokusebenza.
4. Ijika lokushisa le-PCB le-soldering lingaboniswa ngokusekelwe esilinganisweni sesikhathi sangempela.
5. Amasistimu okuhlunga umusi wokushisela ahlolwe isofthiwe yokulingisa ukugeleza komoya okuzinikele angahluza amagesi ayingozi futhi aqinisekise ukuthi i-IN12 ingagcina izinga lokushisa legumbi, ehlise ukulahlekelwa ukushisa futhi ehlise ukusetshenziswa kwamandla okusebenza.
6. Idizayini yepuleti lokufudumeza eliyingqayizivele iqinisekisa ngempumelelo ukuthi i-IN12 izophola ngokulinganayo uma ukushisisa kumisiwe, futhi ivimbela ngokuphumelelayo ukuwohloka nokulimala okubangelwa ukwehla kwezinga lokushisa ngokushesha.
