Kugenzura neza ubushyuhe bwa SMT Reflow Oven kugira ngo kunoze ireme rya Sulding
Ikibazo cyo kugenzura ubushyuhe bwo mu ifuru mu gihe cyo gukora? Iyi ngingo ngenderwaho izagufasha
Mu ikorwa rya SMT (Surface Mount Technology), uburyo bwo kugenzura ubushyuhe bw’ifuru busubiramo buzagena neza ubwiza bw’ubushyuhe n’imikorere y’ibikoresho by’ikoranabuhanga. Ndetse no kunyuranya guto bishobora gutera inenge nko gufungana kw’ibice, icyuho cyangwa kwangirika kw’ibice.
RICH FULL JOY Electronics, ishingiye ku bunararibonye bwinshi mu gukora PCBA n'ubuhanga mu bya tekiniki, yashyizeho "Reflow Oven Temperature Profile Setting Standard," itanga ubuyobozi bwa siyansi, buhamye kandi bufatika bwo kugenzura ubushyuhe bwa SMT reflow oven.
Incamake Isanzwe
Iri hame rireba amafuru yose asubiramo amazi mu iduka ryacu rya SMT, aho injeniyeri za SMT z’inzobere zishinzwe gushyiraho no gucunga ubushyuhe kugira ngo zigenzure neza ubushyuhe mu gihe cyo gusudira.
Gutegura Ibikoresho
Kugira ngo upime neza kandi ushyireho neza imiterere y'ubushyuhe, hakenewe ibikoresho bikurikira: PROFILE tester, insinga za thermocouple, imbaho nyazo za PCB zo gupima, uturindantoki two kurinda, n'ibipimo bya solder paste.
Gushyiraho Amahame Ngenderwaho
1. Ishingiro ry'Ifatizo
Shyiraho ibipimo nk'igipimo cyo kuzamuka, ubushyuhe bw'ibanze, n'ubushyuhe bwo gusubiramo amazi ukurikije imiterere y'udupira dutandukanye two gusoda (urugero: udupira tudafite icyuma, udupira two gusoda dufite icyuma).
2. Ishingiro ry'ibipimo
Imiterere y'ubushyuhe igomba gupimwa ku mbaho nyazo za PCB kugira ngo igaragaze neza ingaruka z'ibidukikije nyirizina ku ihererekanya ry'ubushyuhe.
3. Amahame Rusange
·Igipimo cyo kuzamuka: 1–4℃/s
·Ahantu ho gushyushya mbere: 150–200℃, 60–120s
·Agace ko kongera gushyuha: ≥220℃ kuri sekondi 30–60
·Ubushyuhe bwinshi: 235–250℃
·Igipimo cyo gukonjesha:
4. Ibisabwa byihariye
Hindura umwirondoro wawe hakurikijwe ibitekerezo by'ubuziranenge bw'ibicuruzwa cyangwa ukurikize neza ibisabwa n'abakiriya bawe.
5. Ibipimo byo kuvura ifumbire ya I-Glue
Ubushyuhe bwo gukaraba ifu ya I-glue ni 120°C, igihe cyo gukaraba kiri hagati y'amasegonda 90–150, n'umupaka ntarengwa wa 170°C.
Amabwiriza yo Kwirinda
1. Isuzuma rya buri munsi
Ikizamini cyuzuye cy’ubushyuhe kigomba gukorwa kandi kigafatwa amajwi nyuma yo guhindura umurongo w’amashanyarazi cyangwa uwo gusohora buri munsi.
2. Ikigo gishinzwe ibikorwa
Injeniyeri za SMT z’inzobere ni zo zonyine zemerewe guhindura imiterere y’ubushyuhe.
3. Gukurikiza amabwiriza agenga umukiriya
Shyiraho neza ibipimo by'imikorere hakurikijwe ibisabwa n'umukiriya byo kongera gukoresha.
4. Kubungabunga ibikoresho
Kora ibizamini by'umwuka usohoka mu itanura buri mezi atandatu, urebe ko imikorere yaryo ihoraho. Itandukaniro ry'ubushyuhe hagati y'uturere ntirigomba kurenga 70°C.
Umwanzuro
Binyuze mu gushyira mu bikorwa "Reflow Oven Temperature Profile Setting Standard," RICH FULL JOY Electronics ikora neza cyane mu gusudira SMT, ikongera icyizere mu musaruro no gukora neza kw'ibicuruzwa, kandi igafasha abakiriya kwihutisha igihe cyo kugurisha no kubona inyungu mu ipiganwa.
