PCB (luam tawm cov boardrcuit Court)yog cov cab kuj uas txuas nrog cov qauv hluav taws xob los ntawm kev coj ua ntawm insulating rau lub insulating substrate, muab kev txhawb nqa thiab teeb liab kev xaav txoj kev rau kev tsim tawm, capacitors, chips, thiab lwm yam.
PwB (cov ntawv luam tawm cov hlau board) yog hais txog cov ntawv luam tawm hluav taws xob, uas yog tus thawj coj ntawm PCB thiab yog siv rau kev sib txuas yooj yim ntawm cov khoom. Nws feem ntau yog tsim nyob rau ib sab thiab ua los ntawm cov ntaub ntawv xws li daim ntawv phenolic thiab epoxy iav.
CCA (Circuit Card Ua ke) yog Circuit Card tivthaiv cov khoom siv uas hloov pecb tsis muaj zog los ntawm kev sib sau ua ke los ntawm cov khoom siv hluav taws xob los ua kom tiav cov kab ke hluav taws xob.
Lub ntsiab sib txawv ntawm pwb thiab pcb
PwB feem ntau yog hais txog qhov yooj yim ib leeg-tog sided Circuit Court board nrog tsuas yog cov kab mob thiab tsis muaj cov kab txuas ntxiv. Ntawm qhov tod tes, PCB yog cov lus dav dav uas suav nrog ib tog-ob tog, thiab ntau txheej txheem hluav taws xob, txhua theem nrog cov qib sib txawv ntawm cov nyom.
Qhov sib txawv ntawm cov ntawv luam tawm hluav taws xob thiab cov ntawv luam tawm hluav taws xob tuaj yeem raug xa rov qab mus rau kev txhim kho keeb kwm ntawm ob lub thev naus laus zis. Nyob rau hauv thaum ntxov qib ntawm kev txhim kho tshuab hluav taws xob, luam tawm cov khoom siv hluav taws xob tseem ceeb " Nrog kev nce qib ntawm thev naus laus zis, hluav taws xob cov khoom siv tau ua rau kev txhim kho cov kab ke luam tawm, uas suav nrog ntau txheej ntawm kev coj ua thiab cov khoom sib xyaw.
Hauv kev lag luam hluav taws xob, cov lus PWM thiab PCB feem ntau siv sib hloov pauv sib hloov. Qhov no tuaj yeem ua rau tsis meej pem, tshwj xeeb tshaj yog thaum tham txog cov txiag circuit Court Circuit Court lossis cov txheej txheem tsim kev tsim khoom. Yuav kom tsis txhob muaj kev tsis to taub, nws yog qhov tsim nyog los qhia meej lub ntsiab lus ntawm cov lus thaum sib tham txog cov qauv tsim, tsim khoom, lossis daim ntawv thov ntawm cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob.
Tsim Tsim Kev Tsim Nyog
Lwm qhov sib txawv ntawm cov ntawv luam tawm hluav taws xob thiab cov ntawv luam tawm Circuit Court yog qib kev tsim qauv lawv tuaj yeem haum. Cov ntawv luam tawm cov laug cam feem ntau yog ib leeg-ib tog, nrog cov kev coj ua tsuas yog faib rau ib sab ntawm substrate. Qhov kev tsim qauv no txwv tsis pub muaj qhov nyuaj ntawm cov hluav taws xob uas tuaj yeem ua tiav ntawm Pwbs, ua rau lawv haum cov khoom siv hluav taws xob thiab cov ntawv thov yooj yim dua. Nyob rau hauv sib piv, luam tawm cov laug cam hluav taws xob tuaj yeem yog ib leeg ib leeg, ob sab, lossis ntau txheej txheem, muab cov qauv tsim muaj txiaj ntsig zoo dua thiab ntau dua.
Piv nrog cov neeg ib leeg luam tawm cov laug cam, ob tog luam tawm cov khoom siv hluav taws xob muaj cov kab ke ntawm ob tog, ua cov qauv hluav taws xob ntau dua complex ntau dua. Kev siv ntawm cov qhov muaj peev xwm ua tiav cov hluav taws xob txuas nruab nrab ntawm cov khaubncaws sab nraud thiab cov khaubncaws sab nraud hluav taws xob sab saud thiab qis dua, ntxiv txhim kho cov qauv tsim ntawm ob tog luam tawm cov laug cam.
Multilayer Cov Ntawv Sau Cov Ntaus Circuit Court nce qib tsim kev tsim kom muaj ntau txheej los ntawm kev siv ntau txheej ntawm kev coj ua thiab cov ntaub ntawv insulating thiab insulating cov ntaub ntawv. Qhov no ua rau cov Circuit Court tsim ntau cov txheej txheem ntau, txhim kho cov cim kev ncaj ncees, thiab txhim kho kev tswj hwm thermal. Tus naj npawb ntawm cov khaubncaws sab ntawm cov khaubncaws sab nraud povtseg hauv cov txheej txheem ntau txheej txheem sib txawv sib txawv ntawm plaub mus rau ntau dua 30, nyob ntawm cov ntawv thov yuav tsum tau ua thiab cov kev txwv. Qhov kev nce zuj zus ntawm cov txheej txheem sau cov hluav taws xob ntau cov cim tsim ua kom nws txhawb cov tshuab hluav taws xob siab,siab ntau zausRf circuits, thiab high-density interconns (HD TSIB).
