SMD kev taw qhia
SMT thaj yog hais txog cov ntawv luv ntawm cov txheej txheem txheej txheem ua tiav raws li PCB.PCB (Printed Circuit Board) yog lub rooj tsav xwm luam tawm.
SMT yog Surface Mount Technology (Surface Mount Technology) (lub ntsiab lus rau Surface Mounted Technology), uas yog cov cuab yeej nrov tshaj plaws thiab cov txheej txheem hauv kev lag luam hluav taws xob sib dhos.
Hluav taws xob Circuit Court nto sib dhos tshuab (Surface Mount Technology, SMT), hu ua nto mount lossis nto mount tshuab.Nws yog ib yam uas tsis yog-pin los yog luv-lead nto mount Cheebtsam (SMC / SMD rau luv luv, Suav hu ua nti Cheebtsam) mounted rau saum npoo ntawm lub Circuit Court board (Printed Circuit Board, PCB) los yog nto ntawm lwm yam substrates, los ntawm Circuit Assembly thiab kev sib txuas tshuab uas yog soldered thiab assembled los ntawm txoj kev xws li reflow soldering los yog dip soldering.
Raws li ib txwm muaj, cov khoom siv hluav taws xob uas peb siv yog tsim los ntawm PCB ntxiv rau ntau yam capacitors, resistors thiab lwm yam khoom siv hluav taws xob raws li daim duab kos duab tsim, yog li txhua yam khoom siv hluav taws xob xav tau ntau yam ntawm SMT chip processing thev naus laus zis, Nws txoj haujlwm yog los ua cov khoom siv hluav taws xob. xau solder muab tshuaj txhuam los yog daim nplaum nplaum rau ntawm cov ntaub qhwv ntawm PCB los npaj rau kev sib txuas ntawm cov khoom.Cov cuab yeej siv yog lub tshuab luam ntawv tshuaj ntsuam (screen printing tshuab), uas yog nyob rau hauv pem hauv ntej ntawm SMT ntau lawm kab.
Basic txheej txheem ntawm SMT
1. Printing (silk printing): Nws txoj haujlwm yog los luam cov tshuaj nplaum los yog daim nplaum nplaum rau ntawm cov ntaub qhwv ntawm PCB los npaj rau cov khoom siv soldering.Cov cuab yeej siv yog lub tshuab luam ntawv tshuaj ntsuam (screen printing tshuab), uas yog nyob rau hauv pem hauv ntej ntawm SMT ntau lawm kab.
2. Glue dispensing: Nws yog tso kua nplaum rau ntawm qhov chaw ruaj khov ntawm PCB pawg thawj coj saib, thiab nws lub luag haujlwm tseem ceeb yog kho cov khoom siv rau lub rooj tsavxwm PCB.Cov cuab yeej siv yog cov kua nplaum nplaum, uas yog nyob rau pem hauv ntej ntawm SMT cov kab ntau lawm lossis tom qab cov khoom siv kuaj.
3. Mounting: Nws txoj haujlwm yog txhawm rau txhim kho cov khoom siv saum npoo av mus rau qhov chaw ruaj khov ntawm PCB.Cov cuab yeej siv yog lub tshuab tso chaw, uas nyob tom qab lub tshuab luam ntawv tshuaj ntsuam hauv SMT cov kab ntau lawm.
4. Curing: Nws muaj nuj nqi yog yaj cov nplaum nplaum, kom cov khoom mounting nto thiab cov PCB pawg thawj coj tau ruaj khov ua ke.Cov cuab yeej siv yog lub qhov cub curing, uas nyob tom qab lub tshuab tso rau hauv SMT ntau lawm kab.
5. Reflow soldering: Nws muaj nuj nqi yog kom yaj lub solder muab tshuaj txhuam, kom cov nto mount Cheebtsam thiab PCB board yog ruaj khov ua ke.Cov cuab yeej siv yog lub qhov cub reflow / wave soldering, nyob tom qab lub tshuab tso rau hauv SMT ntau lawm kab.
6. Kev Tu: Nws txoj haujlwm yog tshem tawm cov vuam seem uas tsim kev puas tsuaj rau tib neeg lub cev xws li flux ntawm lub rooj sib dhos PCB.Cov cuab yeej siv yog lub tshuab ntxhua khaub ncaws, thiab qhov chaw yuav tsis raug kho, online lossis offline.
7. Kev tshuaj xyuas: Nws txoj haujlwm yog los tshuaj xyuas qhov vuam zoo thiab kev sib dhos zoo ntawm lub rooj sib dhos PCB.Cov cuab yeej siv suav nrog cov iav tsom iav, tsom iav, lub ntsuas hluav taws xob online (ICT), kev sojntsuam ya davhlau, kev tshuaj xyuas tsis siv neeg kho qhov muag (AOI), X-RAY tshuaj xyuas qhov system, ntsuas kev ua haujlwm, thiab lwm yam. raws li qhov xav tau ntawm kev tshawb nrhiav.
Cov txheej txheem SMT tuaj yeem txhim kho qhov kev ua tau zoo thiab qhov tseeb ntawm cov ntawv luam tawm Circuit Court boards, thiab paub txog qhov kev siv hluav taws xob thiab kev tsim ntau ntawm PCBA.
Xaiv cov khoom siv uas haum rau koj feem ntau tuaj yeem tau txais ob zaug qhov txiaj ntsig nrog ib nrab ntawm kev siv zog.Chengyuan Industrial Automation muab ib qho kev pabcuam thiab kev pabcuam rau SMT thiab PCBA, thiab npaj cov phiaj xwm tsim khoom tsim nyog tshaj plaws rau koj.
