Nyob rau hauv tus txheej txheem ntawmPrint Circuit Court Board ntau lawmthiab kev tsim khoom, tshwj tseg cov txheej txheem npoo yog yooj yim rau txuas ntxiv SMT nto mount ua. Cov txheej txheem txheej txheem tseem ceeb tuaj yeem pab cov plug - hauv kev sib tw ntawm ob lossis txhua sab ntawm PCB Board. Feem ntau los pab ntau lawm, nws tuaj yeem tshem tawm tom qab symt ntau lawm.
Cov txheej txheem tshwj xeeb yuav tau haus ntau tus pcb cov laug cam, yog li nce cov nqi tag nrho ntawm PCB. Feem ntau, nyob ib ncig ntawm 3-10 hli tau tshwj tseg. Ntawm lawv, 5mm yog qhov dav ntau dua.
Lwm yam tsim nyog yuav tsum muaj rau cov txheej txheem ntug
(1) Plaub lub ces kaum ntawm cov txheej txheem ntug tau sib npaug sib npaug nrog lub vojvoog ntawm 5 hli los tiv thaiv kev taw qhia thaum lub sijhawm kis mob.
(2) Txoj kev sib txuas ntawm cov txheej txheem ntug feem ntau adopts v - Cov txheej txheem txiav, ntau dua li cov txheej txheem stamp qhov kev sib txuas. Qhov seem uas seem ntawm v {{3} l}} txiav yog ib {}}}}}}}}}}}}}}}}}}}}
(3) Cov neeg tooj liab luam ntawv ntawm cov txheej txheem ntug yuav tsum muaj dav li 0.4MM yuav tsum tau txhawb nrog rwb thaiv tsev thiab hnav {{tiv taus kev kho.
Kev Tsim Qauv Tshwj Xeeb rau cov txheej txheem cov txheej txheem
(1) SMT lossis TSHUAB ntxig Cheebtsam tsis tuaj yeem raug npaj nyob hauv tus txheej txheem ntug.
(2) Qhov chaw ntawm tes tso Cheebtsam tsis tuaj yeem poob rau hauv ib qho chaw ntawm 3 hli saum toj no cov txheej txheem sab saud thiab qis dua 2 hli saum toj no sab laug thiab txoj cai tswj.
(3) Cov neeg tooj liab luam ntawv hauv cov txheej txheem ntawm cov txheej txheem ntug yuav tsum muaj dav li 0.4Mm yuav tsum tau txhawb nrog rwb thaiv tsev thiab hnav {{tiv taus kev kho. Cov kab sab nraud yuav tsum tsis txhob tsawg dua 0.8mm.
(4) Cov txheej txheem ntug tuaj yeem txuas nrog PCB siv lub pob tw lossis v {{1} duab puab, feem ntau siv v- zoo li tus grooves.
(5) Yuav tsum tsis muaj cov ntaub qhwv txhaws lossis los ntawm qhov ntawm ntug ntawm cov txheej txheem.
(6) ib lub laug cam nrog thaj chaw ntau dua 80 hli ² Yuav tsum muaj lub PCB nws tus kheej kom muaj cov chaw sib koom ua ke nkag rau hauv qhov chaw sab saud thiab hauv qab cov txheej txheem txheej txheem.
