Cia wb mus saib pcb board tsim thiab pcba
Kuv ntseeg tias muaj coob leej ntau tuspaubnrog pcb board tsim thiab feem ntau yuav hnov nws nyob rau hauv lub neej txhua hnub, tab sis lawv yuav tsis paub ntau txog PCBA thiab txawm tias nws tsis meej pem nrog cov ntawv luam tawm.Yog li dab tsi yog pcb board tsim?PCBA tau hloov zuj zus li cas?Nws txawv ntawm PCBA li cas?Cia wb mus saib ntxiv.
* Hais txog pcb board tsim *
Vim nws yog ua los ntawm hluav taws xob luam ntawv, nws yog hu ua "luam" Circuit Court board.Lub rooj tsavxwm pcb yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob hauv kev lag luam hluav taws xob, kev txhawb nqa rau cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob sib txuas ntawm cov khoom siv hluav taws xob.PCB boards tau siv dav hauv kev tsim khoom thiab tsim khoom siv hluav taws xob.Nws cov yam ntxwv tshwj xeeb tuaj yeem sau tau raws li hauv qab no:
1. Cov kab hluav taws xob siab, qhov me me thiab lub teeb yuag yog qhov tsim nyog rau cov khoom siv hluav taws xob miniaturization.
2. Vim yog qhov rov ua tau zoo thiab sib xws ntawm cov duab kos, qhov yuam kev ntawm kev xaim thiab kev sib dhos raug txo, thiab lub sijhawm ntawm kev tu cov cuab yeej, kev debugging thiab tshuaj xyuas tau txais kev cawmdim.
3. Nws muaj txiaj ntsig zoo rau kev siv tshuab thiab kev tsim khoom siv hluav taws xob, txhim kho cov khoom siv hluav taws xob, thiab txo tus nqi ntawm cov khoom siv hluav taws xob.
4. Cov qauv tsim tuaj yeem ua qauv rau kev sib hloov yooj yim.
* Hais txog PCBA *
PCBA yog cov ntawv luv luv ntawm cov ntawv luam tawm Circuit Board + sib dhos, uas yog hais tias, PCBA yog tag nrho cov txheej txheem ntawm kev txuas rau sab sauv ntawm lub board dawb paug ntawm cov ntawv luam tawm Circuit Board thiab dipping.
CEEB TOOM: Nto mount thiab tuag mount yog ob qho tib si ntawm kev sib koom ua ke ntawm lub rooj tsav xwm luam tawm.Qhov sib txawv tseem ceeb yog tias cov thev naus laus zis saum npoo av tsis tas yuav tsum muaj qhov drilling qhov hauv lub rooj tsav xwm luam tawm, cov pins ntawm qhov yuav tsum tau muab tso rau hauv qhov drilling qhov ntawm DIP.
Surface Mount Technology (SMT) Nto mount tshuab feem ntau yog siv lub tshuab tuaj tos thiab tso lub tshuab rau mount qee cov khoom me me ntawm lub rooj tsav xwm luam tawm.Nws cov txheej txheem ntau lawm suav nrog PCB qhov chaw, solder paste luam ntawv, tso tshuab kev teeb tsa, reflow qhov cub thiab tshuaj xyuas kev tsim khoom.
DIPs yog "plug-ins", piv txwv li ntxig qhov chaw ntawm lub rooj tsav xwm luam tawm.Cov khoom no yog qhov loj me thiab tsis haum rau kev siv tshuab thiab ua ke nrog cov plug-ins.Cov txheej txheem tsim khoom tseem ceeb yog: nplaum, plug-in, tshuaj xyuas, yoj soldering, txhuam plating thiab kev tshuaj xyuas kev tsim khoom.
* Qhov sib txawv ntawm PCBs thiab PCBAs *
Los ntawm cov lus qhia saum toj no, peb tuaj yeem paub tias PCBA feem ntau yog hais txog cov txheej txheem ua, thiab tseem tuaj yeem nkag siab tias yog lub rooj tsav xwm ua tiav.PCBA tsuas tuaj yeem suav tau tom qab tag nrho cov txheej txheem ntawm lub rooj tsav xwm luam tawm tiav lawm.Lub rooj tsavxwm luam tawm yog ib lub rooj tsavxwm uas tsis muaj cov ntawv luam tawm uas tsis muaj qhov chaw ntawm nws.
