SMT ndi dzina lathunthu la Surface mount (kapena Mounting) Technology. M'Chitchaina, zikutanthauza kuti Surface yakhazikika (kapena SMT imatanthawuza njira zingapo zozikidwa pa PCB. Printed Circuit Board (PCB) ndi Gulu Losindikizidwa Lozungulira.


Surface Mounted Technology (SMT) ndiye Tekinoloje yodziwika bwino komanso njira zamabizinesi apakompyuta. Electronic circuit Surface Mount Technology (SMT) imatchedwa Surface Mount kapena Surface Mount Technology. SMC/SMD ndi ukadaulo wa Circuit Assembly pomwe pini kapena gawo lalifupi lotsogolera pamwamba (SMC/SMD mu Chitchaina) limayikidwa pamwamba pa Printed Circuit Board (PCB) kapena gawo lina lachigawo ndipo amawotcherera ndikuphatikizidwa ndi kuwotcherera kapena kumizidwa. kuwotcherera.

Nthawi zonse, zinthu zamagetsi zomwe timagwiritsa ntchito zimapangidwa ndi PCB kuphatikiza ma capacitor osiyanasiyana, ma resistors ndi zida zina zamagetsi zomwe zimapangidwa molingana ndi mawonekedwe ozungulira, kotero zida zamagetsi zamitundu yonse zimafunikira ukadaulo wosiyanasiyana wa SMT SMT kuti ugwire ntchito.


Kusindikiza kwa solder -> kuyika magawo --> kuwotchereranso -> AOI optical inspection -> Kukonza --> mbale.


Zamagetsi zamagetsi zimatsata miniaturization, zida zomwe zidagwiritsidwa ntchito kale ndi pulagi-mu sizingachepe. Zogulitsa zamagetsi zimagwira ntchito mokwanira, kugwiritsa ntchito chigawo chophatikizika (IC) kulibe zigawo za perforated, makamaka zazikulu, zophatikizika kwambiri za IC, ziyenera kugwiritsa ntchito zida zapa chip. Kuchuluka kwazinthu, kupanga makina, fakitale yotsika mtengo komanso yotsika kwambiri, imapanga zinthu zapamwamba kwambiri kuti zikwaniritse zofuna za makasitomala ndikulimbitsa mpikisano wamsika wa zida zamagetsi, chitukuko chophatikizika (IC), zida za semiconductor za ntchito zingapo. Kusintha kwa sayansi yamagetsi ndi ukadaulo ndikofunikira, kuthamangitsa zomwe zikuchitika padziko lonse lapansi. Zingaganizidwe kuti pa nkhani ya Intel, AMD ndi mayiko ena opanga ma CPU ndi zipangizo zopangira zithunzi, njira yopangira ma nanometers yapita patsogolo kuposa ma nanometers a 20, chitukuko cha luso la msonkhano wa SMT pamwamba ndi ndondomeko sizingapeweke.


Ubwino wa SMT processing: mkulu kachulukidwe msonkhano, kakang'ono ndi kulemera kuwala kwa zinthu zamagetsi. Kuchuluka ndi kulemera kwa zinthu zamagetsi ndi pafupifupi 1/10 chabe ya zigawo zachikhalidwe za pulagi. Nthawi zambiri, mutatha kutengera SMT, kuchuluka ndi kulemera kwa zinthu zamagetsi zitha kuchepetsedwa ndi 40% ~ 60% ndi 60% ~ 80%. Kudalirika kwakukulu ndi kukana kugwedezeka. Kuwonongeka kwa mgwirizano wa solder ndi kochepa. Makhalidwe abwino apamwamba pafupipafupi. Kuchepetsa kusokoneza kwa ma electromagnetic ndi ma radio frequency. Zosavuta kukwaniritsa zokha, kukonza magwiridwe antchito. Chepetsani mtengo ndi 30% ~ 50%. Sungani zida, mphamvu, zida, ogwira ntchito, nthawi, ndi zina.


Ndi chifukwa cha zovuta za ma SMT processing process, kotero pali mafakitale ambiri opangira ma SMT, okhazikika pakukonza kwa SMT, ku Shenzhen, chifukwa chakukula kwamakampani opanga zamagetsi, kupindula kwa SMT pakutukuka kwamakampani.
