PCB board ntug ua dab tsi

Hauv cov txheej txheem tsim khoom PCB, muaj lwm cov txheej txheem tseem ceeb, uas yog, cov txheej txheem ntug, thiab qhov tshwj xeeb ntawm cov txheej txheem ntug yog qhov tseem ceeb heev rau kev ua tiav SMT tom ntej.

Cov txheej txheem ntug yog ib feem ntxiv rau ntawm ob sab lossis plaub sab ntawm PCB pawg thawj coj saib, feem ntau yog los pab SMT plug-in vuam thiab txav lub rooj tsavxwm, uas yog, nws yooj yim rau kev khiav ntawm SMT qhov chaw tshuab rau clamp lub PCB. board thiab ntws los ntawm lub tshuab tso. Yog hais tias lub caij nyob ze rau ntawm ntug kev thaum lub cuab yeej tau txais los ntawm lub nozzle ntawm SMT qhov chaw tshuab thiab mounted ntawm PCB, kev sib tsoo tej zaum yuav tshwm sim, ua rau tsis ua tiav cov khoom. Yog li ntawd, ib qho txheej txheem ntug yuav tsum tau tshwj tseg, feem ntau nrog qhov dav ntawm 2-5mm. Txoj kev no kuj tseem siv tau rau qee cov khoom siv plug-in los tiv thaiv cov xwm txheej zoo sib xws thaum yoj soldering.

Cov txheej txheem ntug tsis yog ib feem ntawm PCB pawg thawj coj saib thiab tuaj yeem raug tshem tawm tom qab kev tsim khoom ntawm PCBA tiav.

Yuav ua li cas cov khoom siv tes ua ntug ua

1. V-CUT: txheej txheem kev sib txuas ntawm cov txheej txheem ntug thiab lub rooj tsavxwm, me ntsis txiav ntawm ob sab ntawm PCB board, tab sis tsis txiav!

2. Kev sib txuas ntawm cov tav: Siv ob peb lub tav los txuas rau PCB boards, thiab xuas nrig ntaus ib lub qhov nyob hauv nruab nrab, kom lawv tuaj yeem tawg ntawm tes los yog ntxuav los ntawm lub tshuab.

Tsis yog txhua qhov PCB boards yuav tsum tau ua tiav. Yog tias muaj qhov chaw loj ntawm PCB, tawm tsis muaj SMD cov khoom hauv 5 hli ntawm ob sab ntawm PCB. Hauv qhov no, tsis tas yuav ntxiv cov txheej txheem ntug. Muaj lwm qhov teeb meem yog tias tsis muaj SMD Cheebtsam hauv 5 hli ntawm ib sab ntawm pcb pawg thawj coj saib, tsuav yog cov txheej txheem ntug ua tiav ntawm sab nraud, cov no xav tau kev saib xyuas ntawm PCB engineers.

Lub rooj tsavxwm siv los ntawm cov txheej txheem sab yuav ua rau tus nqi tag nrho ntawm PCB. Yog li ntawd, thaum tsim cov txheej txheem PCB, nws yog ib qho tsim nyog yuav tsum sib npaug ntawm kev lag luam thiab kev tsim khoom.

Rau qee qhov tshwj xeeb zoo li PCB boards, thawj PCB board nrog 2 lossis 4 txheej txheem sab tuaj yeem ua kom yooj yim heev los ntawm kev sib tw jigsaw.

Thaum tsim cov txheej txheem jigsaw hauv SMT ua, nws yog ib qho tsim nyog yuav tsum xav txog qhov dav dav ntawm SMT qhov chaw tso tshuab. Rau jigsaw panels nrog ib tug dav tshaj 350mm, nws yog tsim nyog los sib txuas lus nrog tus txheej txheem engineer ntawm lub SMT tsum.
