Tsim ntawm PCB panelization

Ib qhov chaw 1.6mm lossis 2.4mm yuav tsum tau tshwj tseg ntawm txhua lub rooj tsavxwm ntawm PCB hauv lub vaj huam sib luag kom yooj yim rau kev faib cov gongs lossis xuas nrig ntaus. Ntawm plaub fab ntawm lub vaj huam sib luag, NPTH yuav tsum tsim. Tag nrho cov vaj huam sib luag yuav tsum xyuas kom muaj tsawg kawg yog ob lub qhov, thiab lub qhov loj yog 3.05 ± 0.05mm. Qhov nruab nrab ntawm lub qhov yuav tsum tau muab tso rau ntawm lub ces kaum ntawm lub rooj tsavxwm Circuit Court, 5 hli hauv X thiab Y cov lus qhia feem. Plaub lub kaum sab xis ntawm cov vaj huam sib luag yuav tsum tau tsim nrog 5 hli vojvoog R ces kaum kom tsis txhob clamping ntawm txoj siv hlua conveyor.

Lub vaj huam sib luag tsim yuav tsum xyuas kom meej tias qhov kev ncua deb ntawm ntug ntawm qhov taw tes siv thiab lub vaj huam sib luag ntug yog tsawg kawg yog 5 hli. Cov ntsiab lus siv ntawm ob sab yuav tsum tsis txhob muab tso rau qhov sib npaug, uas tuaj yeem tiv thaiv PCB los ntawm kev nkag mus rau hauv lub tshuab rov qab los ntawm kev txheeb xyuas qhov ua haujlwm ntawm lub cuab yeej nws tus kheej. Daim ntawv qhia kev taw qhia tuaj yeem tsim ntawm ntug ntawm lub vaj huam sib luag los tiv thaiv PCB los ntawm kev ua tsis ncaj ncees lawm thaum lub sijhawm tsim khoom. Qhov siab tshaj plaws profileing kam rau ua ntawm lub vaj huam sib luag yuav tsum tswj tsis pub dhau 0.05mm.

Yog tias cov tuam txhab PCB xav tsim cov duab kos duab zoo, lawv yuav tsum muaj cov ntaub ntawv txhawb nqa txaus, txwv tsis pub, cov teeb meem zoo ntawm SMT tom qab sib dhos lossis kev faib tawm yuav tshwm sim vim qhov tsis tsim nyog tsim vaj huam sib luag. Txhawm rau ua kom tiav lub vaj huam sib luag tsim nyog, cov ntaub ntawv hauv qab no feem ntau xav tau. Cov ntaub ntawv Gerber, uas muaj cov khoom faib tawm, txiav txim siab qhov sib faib qhov sib nrug thiab qhov chaw ntawm cov ntsiab lus sib txuas. Kev kos duab profile, nkag siab txog qhov ntev thiab qhov tshwj xeeb. Qhov tshwj xeeb ntawm cov khoom loj, tshwj xeeb tshaj yog cov phaj ntug, yuav tsum tau tsim cov vaj huam sib luag sib nrug, kev zam, thiab lwm yam.

Txawm li cas los xij, PCB sib dhos yog tsim los ua kom tau raws li qhov yuav tsum tau ua los ua ke thiab kev nyab xeeb ntawm SMT. Tom qab sib dhos, nws tseem yuav tsum tau rov qab mus rau lub rooj sib txoos ntawm cov laug cam tiav. Yog li ntawd, tsis hais txog ntawm cov laug cam los yog cov laug cam, ob qho tib si kev sib dhos lub zog yuav tsum tau thiab cov txheej txheem sib cais tom qab kev tsim khoom yuav tsum raug txiav txim siab hauv kev tsim ntawm PCB los ua ke.
