SMT ndi Ubwino Wake M'mabodi Ozungulira

Kodi SMT ndi chiyani? Chifukwa chiyani SMT yakhala ikuvomerezedwa, kuzindikiridwa ndikulimbikitsidwa ndi makampani opanga zamagetsi ikangotuluka? Lero Capel adzakuchotserani m'modzim'modzi.

Surface Mount Technology:

Ndiko kuyikapo phala ngati aloyi ufa (solder phala lalifupi) pa ziyangoyango zonse kuti interconnected pa PCB ndi kusindikiza, malo ❖ kuyanika, kapena kupopera mbewu mankhwalawa, ndiyeno pamwamba phiri zigawo zikuluzikulu (SMC/SMD)) pa malo otchulidwa pamwamba pa PCB, ndiyeno malizitsani remelting ndi kugwirizana kwa solder ince phala kuti amalize phala lonse lapadera pa olowa lonse fur. Njira yolumikizirana ya PCBA. Kutoleredwa kwa matekinolojewa kumatchedwa ukadaulo wa pamwamba mount, dzina la Chingerezi ndi "Surface Mount Technology, SMT mwachidule.

Chifukwa chakuti zinthu zamagetsi zomwe zasonkhanitsidwa ndi SMT zimakhala ndi ubwino wambiri monga kukula kwazing'ono, khalidwe labwino, kudalirika kwapamwamba, njira zopangira zokha, zotulutsa zambiri, zomwe zimagwiritsidwa ntchito mosasinthasintha, komanso mtengo wamtengo wapatali, zakhala zikudziwika kwambiri ndi kuyanjidwa ndi mafakitale a zamagetsi. Ndiye, malondawo atatenga SMT, ndi zabwino zotani zomwe malonda angapindule?

Ubwino wogwiritsa ntchito SMT pazogulitsa:

1. Kuchuluka kwa msonkhano waukulu: Kawirikawiri, poyerekeza ndi ndondomeko ya THT, kugwiritsa ntchito SMT kungachepetse kuchuluka kwa zinthu zamagetsi ndi 60% ndikuchepetsa kulemera kwa 75%;

2. Kudalirika kwakukulu: Zonse zoyamba zodutsa zogwirizanitsa zogulitsa malonda ndi nthawi yochepa pakati pa zolephera (MTBF) zazinthu zakhala zikuyenda bwino;

3. Makhalidwe abwino apamwamba kwambiri: Popeza SMC / SMD nthawi zambiri ilibe kutsogolera kapena njira zazifupi, chikoka cha parasitic inductance ndi capacitance chimachepetsedwa, makhalidwe apamwamba a dera amawongoleredwa bwino, ndipo nthawi yotumizira zizindikiro imafupikitsidwa;

4. Mtengo wotsika: Dera la PCB lomwe limagwiritsidwa ntchito pa SMT ndi 1/12 yokha ya THT yokhala ndi ntchito yomweyo. SMT imagwiritsa ntchito PCB kuchepetsa kubowola kochuluka, zomwe zimachepetsa mtengo wa PCB kupanga; kuchepetsedwa kwa voliyumu ndi khalidwe kumapulumutsa kwambiri mtengo wa kunyamula katundu ndi mayendedwe; mtengo wonse wa mankhwalawa umachepetsedwa kwambiri, ndipo mpikisano wokwanira wazinthu pamsika umakulitsidwa. mphamvu;

5. Yambitsani kupanga makina: Popanga zinthu zambiri, imatha kukhala yokhayokha, yokhala ndi zotulutsa zambiri, mphamvu yayikulu, yokhazikika, yodalirika kwambiri, komanso mtengo wotsika wophatikizira.

Shenzhen Capel Technology Co., Ltd. yakhazikitsa fakitale yopanga bolodi kuyambira 2009 ndipo imapereka misonkhano ya SMT PCB. Pazaka 15 zapitazi, lapeza zambiri, gulu la akatswiri, makina apamwamba ndi zida, komanso luso lapamwamba lopanga. Iwo anathetsa mavuto osiyanasiyana makasitomala 'ntchito vuto.
