Kufotokozera Kwachidule:

SMT ndichidule cha Surface Mounted Technology, Technology yotchuka kwambiri komanso njira yamagetsi yamagetsi yamagetsi. Zamagetsi zamagetsi Pamwamba pa Mount Technology (SMT) amatchedwa Surface Mount kapena Surface Mount Technology. Ndi mtundu wa ukadaulo wamsonkho wa Circuit womwe umakhazikitsa zotsogola kapena zazifupi zotsogolera (SMC / SMD mu Chitchaina) pamwamba pa Printed Circuit Board (PCB) kapena gawo lina, kenako ndikuwotcherera ndi kusonkhanitsa pogwiritsa ntchito kuwotcherera kapena kuviika kuwotcherera.

SMT ndichidule cha Surface Mounted Technology, Technology yotchuka kwambiri komanso njira yamagetsi yamagetsi yamagetsi. Zamagetsi zamagetsi Pamwamba pa Mount Technology (SMT) amatchedwa Surface Mount kapena Surface Mount Technology. Ndi mtundu wa ukadaulo wamsonkho wa Circuit womwe umakhazikitsa zotsogola kapena zazifupi zotsogolera (SMC / SMD mu Chitchaina) pamwamba pa Printed Circuit Board (PCB) kapena gawo lina, kenako ndikuwotcherera ndi kusonkhanitsa pogwiritsa ntchito kuwotcherera kapena kuviika kuwotcherera.

Mwambiri, zida zamagetsi zomwe timagwiritsa ntchito zimapangidwa ndi PCB kuphatikiza ma capacitors osiyanasiyana, ma resistor ndi zida zina zamagetsi kutengera chithunzithunzi cha dera, kotero mitundu yonse yamagetsi yamagetsi imafunikira ukadaulo wosakanikira wa SMT.

Njira zoyambira za SMT zimaphatikizapo: kusindikiza pazenera (kapena kugawa), kukonza (kuchiritsa), kuwotcherera, kutsuka, kuyesa, kukonza.

1. Kusindikiza pazenera: Ntchito yosindikiza pazenera ndikutulutsa phala la solder kapena zomatira pazitsulo za PCB pokonzekera kuwotcherera kwa zinthu. Zipangizo zomwe amagwiritsa ntchito ndi makina osindikizira (makina osindikizira pazenera), omwe ali kumapeto kwa mzere wopanga wa SMT.

2. Kupopera kumata: Amagwetsa guluu pamalo okhazikika a bolodi la PCB, ndipo ntchito yake yayikulu ndikukonzekera zigawo za bolodi la PCB. Zipangizo zomwe amagwiritsa ntchito ndimakina operekera, omwe amakhala kumapeto kwa mzere wopanga wa SMT kapena kumbuyo kwa zida zoyesera.

3. Phiri: Ntchito yake ndikukhazikitsa zigawo za msonkhano pamwamba molondola pa PCB. Zipangizo zomwe zimagwiritsidwa ntchito ndi makina osungira a SMT, omwe ali kuseri kwa makina osindikizira pazithunzi za THE SMT.

4.Kuchiritsa: Ntchito yake ndikusungunula zomatira za SMT kotero kuti zigawo zamisonkhano yayikulu ndi bolodi la PCB zitha kumamatira limodzi. Zipangizo zomwe amagwiritsidwa ntchito ndikuchiritsa ng'anjo, yomwe ili kumbuyo kwa mzere wopanga wa SMT SMT.

5. Reflow kuwotcherera: ntchito ya reflow kuwotcherera ndi kusungunula ndi solder phala, kotero kuti pamwamba msonkhano zigawo zikuluzikulu ndi bolodi PCB mwamphamvu amamangirira pamodzi. Zipangizo zomwe zimagwiritsidwa ntchito ndikuwotchera ng'anjo, yomwe ili mu mzere wopanga wa SMT kuseri kwa makina oyikira a SMT.

6. Kukonza: Ntchitoyi ndikuchotsa zotsalira za kuwotcherera monga kutuluka pa PCB komwe kumawononga thupi la munthu. Zipangizo zomwe zimagwiritsidwa ntchito ndi makina oyeretsera, malowa sangakonzedwe, atha kukhala pa intaneti, kapena ayi pa intaneti.

7. Kuzindikira: Amagwiritsidwa ntchito kuti azindikire mtundu wowotcherera komanso mtundu wa msonkhano wa PCB. Zipangizo zomwe zimagwiritsidwa ntchito zikuphatikiza galasi lokulitsira, maikulosikopu, chida choyesera pa intaneti (ICT), chida choyesera singano chouluka, kuyesa kwamagetsi (AOI), kuyesa kwa X-ray, chida choyesera, ndi zina zambiri. gawo la mzere wopanga malinga ndi zofunikira pakuwunika.

8.Konzani: imagwiritsidwanso ntchito kukonzanso PCB yomwe yapezeka ndi zolakwika. Zida zomwe amagwiritsidwa ntchito ndizitsulo zosungunulira, malo ogwiritsira ntchito, ndi zina zambiri. Makonzedwe ali paliponse pamzere wopanga.
