Cov hom PCB
PCB tuaj yeem muab faib ua lub rooj sib txig sib luag, hloov pauv hloov lub rooj sib txig, thiab pawg thawj coj sib luag.
General PCB hu ua PCB yeem. Qhov pom ntawm qhov sib txawv ntawm PCB nruj heev thiab yooj ywm PCB yog qhov hloov tau PCB tuaj yeem ua tau khoov. Cov tuab tuab ntawm cov yeem txhav PCB yog 0.2 hli, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm, thiab lwm yam Thiab cov tuab ntawm tuab ntawm yooj ywm PCB yog 0.2 hli, thiab cov tuab tuab txheej yuav ntxiv tom qab ntawm feem yuav tsum tau welded. Lub txheej tuab ntawm cov tuab tuab sib txawv nws txawv ntawm 0.2 hli mus rau 0.4 hli. Lub hom phiaj ntawm kev nkag siab cov no yog los muab qhov chaw dav rau cov qauv engineers thaum lawv tsim. Cov khoom siv dav dav ntawm cov tawv ntoo PCB muaj xws li: phenolic ntawv laminate, epoxy ntawv laminate, polyester iav muaj kev laminate, epoxy iav ntaub laminate; cov ntaub ntawv siv dav ntawm yooj ywm PCB suav nrog: polyester zaj duab xis, polyimide zaj duab xis, FEP zaj duab xis.
Raws li tus naj npawb ntawm cov ntawv cog lus, Circuit Court PCB tuaj yeem muab faib ua ib lub vaj huam sib luag, muab ob npaug ntawm daim txiag thiab lub rooj tsav xwm multilayer. Lub rooj zaum ntau txheej yog 4-txheej board los yog 6-txheej board, thiab lub rooj tsav xwm ntau pawg ua ke tuaj yeem mus txog kaum ob txheej.
Ib lub vaj huam sib luag
Ib leeg ib sab. Ntawm cov PCB yooj yim tshaj plaws, qhov chaw kub siab yog rau ntawm ib sab, thaum cov xaim muaj nyob ntawm lwm sab (thaum muaj cov Cheebtsam nti, lawv yog cov tib yam li xaim, thiab cov khoom siv sib txuas yog nyob rau sab nraud). Vim tias cov xov hlau tsuas tshwm rau ntawm ib sab, PCB hom no hu ua ib sab. Vim tias muaj ntau txoj kev txwv nruj rau kev tsim qauv ntawm lub vaj huam sib luag (vim tias tsuas muaj ib sab, cov xov hluav taws xob tsis tuaj yeem hla thiab yuav tsum nyob ib puag ncig ntawm txoj kev ywj pheej), tsuas yog cov kab hluav taws xob thaum ntxov siv xws li cov laug cam.
Muab ob daim txiag sau ua ke
Cov laj kab uas muaj ob sab sib txuas muaj xaim ntawm ob tog ntawm lub rooj tsav xwm, tab sis kom siv cov xov hlau ntawm ob sab, nws yog qhov tsim nyog kom muaj txoj kab sib txuas ntawm qhov txuas ntawm ob tog." choj" nruab nrab ntawm cov xaim hluav taws xob no hu ua qhov sim (ntawm). Cov lus qhia ua lub qhov yog lub qhov me me uas tau sau los yog lo nrog cov hlau ntawm PCB, tuaj yeem txuas nrog cov xov hlau ntawm ob tog. Vim tias thaj tsam ntawm ob daim txiag ob npaug yog ob zaug loj dua li ntawm tib lub vaj huam sib luag, ob lub vaj huam sib luag daws teeb meem ntawm cov xov hlau tsis sib haum hauv tib lub vaj huam sib luag (nws tuaj yeem ua mus rau lwm sab dhau los ntawm qhov), uas yog qhov haum rau kev ua haujlwm zoo sib xws ntau dua li ntawm ib lub vaj huam sib luag.
Multilayer board
Txhawm rau nce thaj tsam ntawm cov xov hlau, ntau txheej txheej siv ntau txheej txheem ib leeg lossis ob npaug ntawm cov xov hlau txuas. Daim txiag hluav taws xob luam tawm nrog ib txheej ob txheej dhau li txheej sab hauv, ob txheej txheej tib leeg li txheej txheej sab nraud lossis ob txheej txheej dhau li txheej sab hauv thiab ob txheej txheej dhau li txheej txheej sab nraud. Cov ntawv luam tawm Circuit Circuit uas txuas nrog kev sib txuas los ntawm kev teeb tsa kev ua haujlwm thiab insulating daim ntawv cog lus cov khoom sib txuas thiab nws cov duab hluav taws xob sib txuas tau zoo raws li cov qauv tsim yuav dhau los ua plaub-txheej thiab rau-txheej luam tawm Circuit Court board, tseem hu ua ntau txheej txheej Circuit Court board. Tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm lub rooj tsavxwm tsis txhais tau hais tias muaj ob peb txheej txheej hlau ywj pheej. Hauv qee qhov tshwj xeeb, txheej dawb yuav ntxiv los tswj pawg tuab. Feem ntau, cov naj npawb ntawm cov khaubncaws sab nraud yog txawm thiab suav nrog sab nraud ntawm ob txheej. Feem ntau ntawm cov motherboard yog 4 rau 8-txheej txheej, tab sis hauv kev tshawb xav, nws muaj peev xwm ua tiav yuav luag 100 txheej ntawm PCB. Feem ntau ntawm cov supercomputers loj tau siv ntau tus lej ntawm cov motherboards, tab sis vim hais tias cov khoos phis tawm no tuaj yeem hloov los ntawm ntau cov koos pis tawj uas siv tau zoo heev, cov cuab yeej ultra ntau txheej tau maj mam tawm ntawm kev siv. Vim tias cov khaubncaws sab nraud povtseg hauv PCB tau sib xyaw zoo, feem ntau nws tsis yooj yim pom tus lej tseeb, tab sis yog tias koj ua tib zoo saib daim ntawv tseem ceeb, koj tseem tuaj yeem pom.
Yam ntxwv
Qhov laj thawj yog vim li cas PCB tuaj yeem siv ntau dua thiab ntau dua siv tau yog tias nws muaj ntau lub zog zoo, raws li hauv qab no.
Cov ntom ntom. Rau xyoo lawm, lub siab ntawm PCB tau tsim kho nrog kev txhim kho ntawm IC kev sib xyaw thiab tshuab thev naus laus zis.
Muaj kev cia siab rau. Los ntawm kev tshuaj xyuas tas mus li, kuaj thiab laus dua, PCB tuaj yeem lav ua haujlwm kom zoo rau ntev (feem ntau 20 xyoo).
Kev tsim qauv. Rau cov kev ua tau zoo hauv PCB (hluav taws xob, lub cev, tshuaj lom neeg, tshuab, thiab lwm yam), tsim qauv PCB tuaj yeem paub los ntawm kev tsim qauv, qauv qauv, thiab lwm yam, nrog lub sijhawm luv luv thiab kev ua haujlwm siab.
Tsim Kom Muaj. Nrog cov kev tswj hwm niaj hnub, kev tsim qauv, teev (ntau npaum li cas), kev siv tshuab tsis siv neeg thiab lwm yam tuaj yeem nqa tawm kom ntseeg tau tias cov khoom zoo.
Kev kuaj ntshav. Ib tus qauv ua tiav kev sib tw, ntsuas cov qauv, ntau yam khoom siv ntsuas, thiab cov twj paj nruag raug tsim los ntsuas thiab txheeb xyuas cov khoom lag luam tsim nyog PCB thiab kev pab lub neej.
Kev Sib Tw. Kunshan JINGDING hluav taws xob PCB cov khoom lag luam tsis yog tsuas yog yooj yim rau cov txheej txheem sib dhos ntawm ntau yam, tab sis kuj siv rau kev ua haujlwm tsis siv neeg thiab loj-loj. Nyob rau tib lub sijhawm, PCB thiab ntau yam ntawm cov khoom sib dhos ua ke kuj tuaj yeem sib sau los ua cov kab loj, tshuab, thiab lub tshuab tag nrho.
Txij nkawm zoo. Vim tias cov khoom lag luam PCB thiab ntau cov khoom siv sib dhos tau tsim tawm hauv cov qauv tsim thiab cov qauv, cov ntu no kuj tau dhau los. Yog li no, thaum lub kaw lus tawg, nws tuaj yeem hloov tau sai, yooj yim thiab hloov tau, thiab lub kaw lus yuav rov qab tau sai. Yog lawm, muaj ntau cov piv txwv. Xws li miniaturization, lub teeb yuag, lub teeb liab siab kis thiab lwm yam.
Kab lus thiab cov duab hauv Is Taws Nem, yog muaj ib qho dab tsi thov hu rau peb kom tshem tawm.
