Qhov sib txawv ntawm PCB thiab PCB los ua ke

PCBA yog dab tsi

PCBA yog lub npe luv ntawmprinted Circuit Board los ua ke.Nws txhais tau tias, cov PCBs liab qab mus txog tag nrho cov txheej txheem ntawm SMT thiab DIP plug-in.

SMT thiab DIP yog ob qho tib si rau kev sib koom ua ke ntawm PCB pawg thawj coj saib.Qhov sib txawv tseem ceeb yog SMT tsis tas yuav tho qhov ntawm PCB board.Hauv DIP, koj yuav tsum ntxig tus PIN rau hauv lub qhov drilled.

Dab tsi yog SMT (Nto Mounted Technology)

Surface Mounted Technology tsuas yog siv lub tshuab mount rau mount qee qhov micro rau PCB board.Cov txheej txheem ntau lawm yog: PCB board positioning, luam ntawv solder paste, mount tshuab mounted, reflow rauv thiab ua tiav kev soj ntsuam.Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, SMT kuj tseem tuaj yeem txhim kho qee qhov loj-loj, xws li: qee qhov loj-loj mechanism tuaj yeem ntsia tau rau ntawm lub motherboard.

SMT PCB sib dhoskev koom ua ke yog rhiab rau qhov chaw thiab qhov loj me.Tsis tas li ntawd, qhov zoo ntawm solder paste thiab luam ntawv zoo kuj ua lub luag haujlwm tseem ceeb.

DIP yog "plug-in", uas yog ntxig rau hauv PCB board.Vim tias qhov loj ntawm cov khoom yog loj thiab nws tsis haum rau mounting los yog thaum lub chaw tsim tshuaj paus siv tsis tau SMT assembling technology, thiab lub plug-in yog siv los integrate cov khoom.Tam sim no, muaj ob txoj hauv kev kom paub txog phau ntawv plug-in thiab neeg hlau plug-in hauv kev lag luam.Cov txheej txheem tsim khoom tseem ceeb yog: rov qab ua kua nplaum (kom tiv thaiv cov tin plating rau qhov chaw uas yuav tsum tsis txhob plated), ntsaws-hauv, tshuaj xyuas, yoj soldering, phaj txhuam (kom tshem tawm cov stains sab laug hauv cov txheej txheem ntawm lub cub tawg) thiab ua tiav. kev tshuaj xyuas.

PCB yog dab tsi

PCB txhais tau tias cov ntawv luam tawm Circuit Board, uas tseem hu ua cov ntawv xov hluav taws xob.PCB yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, kuj yog kev txhawb nqa ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob sib txuas ntawm cov khoom siv hluav taws xob.Vim nws ua los ntawm hluav taws xob luam ntawv, thiab hu ua luam tawm Circuit Board.

Tom qab siv PCB rau cov khoom siv hluav taws xob, vim yog qhov sib xws ntawm tib yam ntawm PCB, kev siv cov khoom siv hluav taws xob tsis zoo tuaj yeem zam tau, thiab cov khoom siv hluav taws xob tuaj yeem raug txiav los yog muab tso rau hauv, txiav soldered, thiab kuaj pom, kom ntseeg tau qhov zoo. ntawm cov khoom siv hluav taws xob, thiab txhim kho kev ua haujlwm ntawm kev ua haujlwm, txo tus nqi thiab pab txhawb kev txij nkawm.

PCB tuaj yeem siv ntau thiab ntau dua, vim nws muaj ntau yam zoo:

1. High density: Tau ntau xyoo lawm, PCB siab ceev tuaj yeem txhim kho nrog kev txhim kho ntawm IC kev koom ua ke thiab kev siv tshuab.
2. Kev ntseeg siab.Los ntawm kev tshuaj xyuas, kev sim thiab kev laus, PCB tuaj yeem ua haujlwm tau ntev (feem ntau 20 xyoo).
3. ŸDesignability.Rau PCB kev ua tau zoo yuav tsum tau (hluav taws xob, lub cev, tshuaj, khoom siv, thiab lwm yam), PCB tsim tuaj yeem ua tiav los ntawm kev tsim 4. Kev tsim qauv, kev tsim qauv, thiab lwm yam, nrog lub sijhawm luv luv thiab kev ua haujlwm siab.
5. ŸProducibility.Nrog rau kev tswj xyuas niaj hnub no, kev tsim qauv, ntsuas (ntau), automation thiab lwm yam khoom tuaj yeem ua tiav los xyuas kom meej qhov sib xws ntawm cov khoom zoo.
6. ŸTestability.Tsim ib txoj kev sim ua tiav, cov qauv ntsuas, ntau yam khoom siv thiab cov cuab yeej siv los kuaj xyuas thiab txheeb xyuas cov khoom tsim nyog PCB thiab kev pabcuam lub neej.
7. Kev sib sau ua ke.Cov khoom siv PCB tsis yog tsuas yog yooj yim rau kev sib dhos ntawm ntau yam khoom, tab sis kuj rau kev ua haujlwm tsis siv neeg thiab cov khoom loj loj.Nyob rau tib lub sijhawm, PCB thiab ntau yam khoom siv sib dhos tuaj yeem sib sau ua ke los tsim cov khoom loj, tshuab, thiab txawm tias tag nrho lub tshuab.
8. ŸMaintainability.Cov khoom siv PCB thiab ntau yam khoom sib dhos yog tsim thiab ua raws li cov qauv, cov khoom no kuj yog tus qauv.Yog li ntawd, thaum lub kaw lus tsis ua haujlwm, nws tuaj yeem hloov tau sai, yooj yim thiab yoog raws, thiab lub kaw lus tuaj yeem rov qab tau sai.Tau kawg, muaj ntau yam piv txwv.Xws li ua rau lub kaw lus miniaturization, lub teeb yuag, kev kub ceev teeb liab kis tau tus mob thiab lwm yam.

Dab tsi yog qhov txawv ntawm PCB thiab PCBA

1. PCB hais txog Circuit Board, thaum PCBA hais txog kev sib dhos ntawm Circuit Board plug-in, SMT txheej txheem.
2. Ua tiav board thiab liab qab board
3. PCB yog luam tawm lub rooj tsavxwm, uas yog ua los ntawm epoxy iav resin.Nws muab faib ua 4, 6 thiab 8 txheej raws li cov teeb liab sib txawv.Feem ntau yog 4 thiab 6-txheej 4. boards.Chip thiab lwm cov ntsiab lus thaj yog txuas rau PCB.
5. PCBA tuaj yeem nkag siab tias yog lub rooj tsav xwm ua tiav uas yog tom qab cov txheej txheem ntawm lub rooj tsav xwm Circuit Court ua tiav thiab nws tuaj yeem hu ua PCBA.
6. PCBA = Printed Circuit Board + Sib dhos
7. Cov PCBs liab qab mus txog tag nrho cov txheej txheem ntawm SMT thiab dip plug-in, nws yog hu ua PCBA luv luv.

PCB yog lub npe luv ntawm cov ntawv luam tawm Circuit Board.Nws yog feem ntau hu ua luam tawm Circuit Court uas yog ua los ntawm cov ntawv luam tawm Circuit Court, cov khoom luam tawm los yog cov qauv siv hluav taws xob tsim los ntawm kev sib xyaw ntawm cov ntawv luam tawm thiab cov ntawv luam tawm Circuit Board.Tus qauv conductive uas muab hluav taws xob sib txuas ntawm cov khoom ntawm insulating substrate yog hu ua luam Circuit Court.Nyob rau hauv txoj kev no, cov ntawv luam tawm lossis cov ntawv ua tiav ntawm cov ntawv luam tawm yog hu ua cov ntawv luam tawm Circuit board, tseem hu ua cov ntawv luam tawm los yog cov ntawv luam tawm.

Tsis muaj ib feem ntawm tus qauv PCB, uas feem ntau hu ua "cov ntaub ntawv xov tooj (PWB)"
