Kusintha kwa SMTndi mndandanda wa luso ndondomeko processing pamaziko a PCB. Zili ndi ubwino wokwera kwambiri komanso kuthamanga kwachangu, kotero zakhala zikuvomerezedwa ndi opanga magetsi ambiri. SMT chip processing process makamaka imaphatikizapo silika chophimba kapena guluu dispens, kukwera kapena kuchiritsa, reflow soldering, kuyeretsa, kuyesa, kukonzanso, ndi zina zotero. Njira zingapo zimachitika mwadongosolo kuti amalize ntchito yonse yokonza chip.
1.Kusindikiza pazenera
Zida zakutsogolo zomwe zili mumzere wopangira wa SMT ndi makina osindikizira pazenera, omwe ntchito yake yayikulu ndikusindikiza phala la solder kapena patch glue pamapadi a PCB kukonzekera kugulitsa zinthu.
2. Kupereka
Zida zomwe zili kumapeto kwa mzere wopanga wa SMT kapena kuseri kwa makina oyendera ndi chopangira guluu. Ntchito yake yayikulu ndikugwetsa guluu pamalo okhazikika a PCB, ndipo cholinga chake ndikukonza zida za PCB.
3. Kuyika
Zipangizo zomwe zili kumbuyo kwa makina osindikizira a silika mumzere wopanga ma SMT ndi makina oyika, omwe amagwiritsidwa ntchito kuyika bwino zida zapamtunda pamalo okhazikika pa PCB.
4. Kuchiritsa
Zida zomwe zili kumbuyo kwa makina opangira makina a SMT ndi ng'anjo yochiritsa, yomwe ntchito yake yaikulu ndikusungunula guluu woyika, kuti zigawo za pamwamba ndi bolodi la PCB zigwirizane mwamphamvu.
5. Reflow soldering
Zida zomwe zili kumbuyo kwa makina oyika mu mzere wopanga SMT ndi uvuni wa reflow, womwe ntchito yake yayikulu ndikusungunula phala la solder kuti zigawo zokwera pamwamba ndi bolodi la PCB zigwirizane mwamphamvu.
6. Kuzindikira
Pofuna kuwonetsetsa kuti mtundu wa soldering ndi khalidwe la msonkhano wa bolodi la PCB lomwe linasonkhana likukwaniritsa zofunikira za fakitale, magalasi okulitsa, ma microscopes, zoyesera zozungulira (ICT), zoyesa zowuluka zowuluka, kuyang'anira maso (AOI), makina oyendera a X-RAY. ndi zida zina zofunika. Ntchito yayikulu ndikuzindikira ngati bolodi ya PCB ili ndi zolakwika monga kugulitsa pafupifupi, kusowa kwa soldering, ndi ming'alu.
7. Kuyeretsa
Pakhoza kukhala zotsalira za soldering zovulaza thupi la munthu monga kutuluka pa bolodi la PCB lomwe linasonkhana, lomwe liyenera kutsukidwa ndi makina oyeretsera.
