Ukulawulwa Okunembile Kokushisa Kwe-SMT Reflow Oven Ukuze Kuthuthukiswe Ikhwalithi Yokushisela
Unenkinga Yokulawula Ukushisa Kwe-Oven Okuphinda Kugeleze Ngesikhathi Sokukhiqiza? Le Nqubo Yokusetha Izosiza
Enqubweni yokukhiqiza ye-SMT (Surface Mount Technology), ukunemba kokulawula izinga lokushisa le-oven kabusha kunquma ngqo ikhwalithi yokushisela kanye nokusebenza komkhiqizo we-elekthronikhi. Ngisho nokuphambuka okuncane kungaholela ezifweni ezifana namajoyinti e-solder abandayo, ama-voids, noma umonakalo wezingxenye.
I-RICH FULL JOY Electronics, ngokusekelwe kokuhlangenwe nakho okubanzi kokukhiqiza kwe-PCBA kanye nobuchwepheshe, ithuthukise "i-Reflow Oven Temperature Profile Setting Standard," enikeza isiqondiso sesayensi, esihlelekile, nesisebenzayo sokulawula izinga lokushisa le-oven reflow ye-SMT.
Ukubuka Okujwayelekile
Le nqubo isebenza kuwo wonke ama-oven aphinde ageleze endaweni yethu yokusebenzela ye-SMT, onjiniyela be-SMT abangochwepheshe abanomthwalo wokubeka nokuphatha amaphrofayili okushisa ukuqinisekisa ukulawulwa okunembile kokushisa ngesikhathi sokushisela.
Ukulungiselela Amathuluzi
Ukuze kulinganiswe futhi kusethwe amaphrofayili okushisa ngokunembile, kudingeka amathuluzi alandelayo: Isihloli se-PROFILE, izintambo ze-thermocouple, amabhodi e-PCB angempela okulinganisa, amagilavu okuvikela, kanye nemininingwane yokunamathisela i-solder.
Ukubeka Izindinganiso
1. Isisekelo Sokubhekisela
Setha amapharamitha afana nesilinganiso sokukhuphuka, izinga lokushisa lokushisa kusengaphambili, kanye nezinga lokushisa lokugeleza kabusha ngokusekelwe ezicini zama-solder paste ahlukene (isb., ama-solder paste angenawo umthofu, ane-lead).
2. Isisekelo Sokulinganisa
Amaphrofayili okushisa kumele alinganiswe emabhodini e-PCB angempela ukuze abonise ngokunembile imiphumela yezindawo zokukhiqiza zangempela ekudlulisweni kokushisa.
3. Izindinganiso Ezijwayelekile
·Izinga Lokunyuka: 1–4℃/s
·Indawo Yokushisa Ngaphambi Kokushisa: 150–200℃, 60–120s
·Indawo Yokugeleza Kabusha: ≥220℃ kumasekhondi angu-30–60
·Izinga lokushisa eliphakeme: 235–250℃
·Izinga Lokupholisa:
4. Izidingo Ezikhethekile
Lungisa iphrofayili ngokuguquguqukayo ngokusekelwe kumpendulo yekhwalithi yomkhiqizo noma ulandele ngokuqinile izidingo zamakhasimende ezenziwe ngokwezifiso.
5. Amapharamitha Okwelapha I-I-Glue
Izinga lokushisa lokulungisa i-glue elingu-1 lingu-120℃, isikhathi sokulungisa siphakathi kwemizuzwana engama-90-150, kanye nomkhawulo omkhulu ongu-170℃.
Izinyathelo zokuzivikela
1. Ukuhlolwa Kwansuku Zonke
Ukuhlolwa kwephrofayili yokushisa okugcwele kumele kwenziwe futhi kuqoshwe ngemuva kokushintsha umugqa wokuvula noma wokukhiqiza nsuku zonke.
2. Igunya Lokusebenza
Onjiniyela be-SMT abangochwepheshe kuphela abagunyaziwe ukushintsha izilungiselelo zephrofayili yokushisa.
3. Ukuthobela Imigomo Yekhasimende
Setha ngokuqinile amapharamitha enqubo ngokuya ngezidingo zokugeleza kabusha ezichazwe yikhasimende.
4. Ukulungiswa Kwemishini
Yenza ukuhlolwa kokugeleza komoya kohlelo lokukhipha umoya lwehhavini eliphinde ligeleze njalo ezinyangeni eziyisithupha, uqinisekise ukusebenza okuzinzile. Umehluko wokushisa phakathi kwezindawo akumele udlule ku-70℃.
Isiphetho
Ngokusebenzisa i-"Reflow Oven Temperature Profile Setting Standard," i-RICH FULL JOY Electronics iqinisekisa ukushisela kwe-SMT kwekhwalithi ephezulu, ithuthukisa ukuthembeka kokukhiqiza kanye nokusebenza komkhiqizo, futhi isiza amakhasimende ukusheshisa isikhathi sokuya emakethe futhi athole izinzuzo zokuncintisana.
