Kupanga kwa mzere wopanga wa SMT

Zithunzi za SMT akhoza kugawidwa mu mizere zodziwikiratu kupanga ndi mizere theka-zodziwikiratu kupanga malinga ndi mlingo wa zochita zokha, ndipo akhoza kugawidwa mu mizere lalikulu, sing'anga ndi yaing'ono kupanga malinga ndi kukula kwa mzere kupanga.Mzere wodziwikiratu wodziwikiratu umatanthawuza zida zonse zopangira zida zodziwikiratu, kudzera pamakina odziwikiratu, makina otsitsa ndi mzere wa buffer adzakhala onse pamodzi ngati zida zopangira mzere, theka-yodziwikiratu kupanga mzere ndiye zida zazikulu zopangira si. olumikizidwa kapena osalumikizidwa, makina osindikizira ndi okhazikika, amafunikira kusindikiza kapena kutsitsa ndikutsitsa PCB.

1. Kusindikiza: ntchito yake ndikutulutsa phala la solder kapena guluu pagulu la solder la PCB kukonzekera kuwotcherera zigawo.Zida zomwe zimagwiritsidwa ntchito ndimakina osindikizira a solder, yomwe ili kumapeto kwa mzere wopanga ma SMT.
2, kugawa: ndikugwetsa guluu pamalo okhazikika a PCB, ntchito yake yayikulu ndikukonza zida za PCB board.Zida zomwe zimagwiritsidwa ntchito ndi makina operekera, omwe ali kumapeto kwa mzere wopanga SMT kapena kuseri kwa zida zoyesera.

3, phiri: ntchito yake ndikukhazikitsa molondola zigawo zikuluzikulu za msonkhano pa malo okhazikika a PCB.Zida zomwe zimagwiritsidwa ntchito ndi makina osankha ndi kuika, omwe ali kuseri kwa makina osindikizira mumzere wopangira SMT.
4. Kuchiritsa: ntchito yake ndi kusungunula zomatira patch, kotero kuti zigawo za msonkhano wapamwamba ndi PCB zimagwirizanitsidwa mwamphamvu.Zida zomwe zimagwiritsidwa ntchito ndi ng'anjo yochiritsa, yomwe ili kuseri kwa mzere wopanga wa SMT.

5. Reflow soldering: ntchito yake ndi kusungunula solder phala ndi kupanga pamwamba pa msonkhano zigawo zikuluzikulu ndi PCB zolimba omangika pamodzi.Zida zomwe zimagwiritsidwa ntchito ndi areflow uvuni, yomwe ili kuseri kwa mzere wopanga wa SMT SMT SMT.
6. Kuyeretsa: ntchito yake ndikuchotsa zotsalira zowotcherera (monga flux, etc.) zomwe zimakhala zovulaza thupi la munthu pa PCB yosonkhanitsidwa.Zida zomwe zimagwiritsidwa ntchito ndi makina otsuka, malowo sangathe kukhazikitsidwa, akhoza kukhala pa intaneti, komanso osati pa intaneti.

6. Mayeso: ntchito yake ndi kuyesa khalidwe kuwotcherera ndi khalidwe msonkhano wa anasonkhana PCB.Zida zomwe zimagwiritsidwa ntchito zimaphatikizapo galasi lokulitsa, microscope, Tester ya pa intaneti (In circuit Tester, ICT), Tester ya singano yowuluka, Automated OpticalInspection (AOI), X-ray detection system, ntchito Tester, ndi zina zotero. malo a mzere wopanga molingana ndi zosowa zoyezetsa.
8. Kukonza: ntchito yake ndikukonzanso PCB yomwe yazindikira zolakwika.Chida chomwe chimagwiritsidwa ntchito ndi chitsulo chosungunuka, chomwe chimagwiritsidwa ntchito pokonza ntchito.
