Lub ntsiab lus ntawm cov ntawv luam tawm Circuit Board thiab nws cov kev faib tawm

Printed circuit boards, tseem hu ualuam tawm Circuit Boards, yog cov chaw muab kev sib txuas hluav taws xob rau cov khoom siv hluav taws xob.
Lub rooj tsav xwm luam tawm feem ntau yog sawv cev los ntawm "PCB", tab sis tsis tuaj yeem hu ua "PCB board".
Kev tsim ntawm cov ntawv luam tawm Circuit Board yog qhov tsim qauv tsim;Lub ntsiab kom zoo dua ntawm kev siv lub rooj tsavxwm Circuit Court yog kom txo tau cov xaim thiab kev sib dhos yuam kev, thiab txhim kho qib automation thiab kev ua haujlwm ntau lawm.
Printed Circuit Boards tuaj yeem muab faib ua ib leeg, ob sab, plaub-txheej, rau-txheej thiab lwm cov txheej txheem ntau txheej raws li tus naj npawb ntawm cov rooj sib tham.
Txij li thaum lub rooj tsavxwm luam tawm tsis yog cov khoom siv dav dav, lub ntsiab lus ntawm lub npe yog me ntsis ruam.Piv txwv li, lub motherboard rau tus kheej lub computer yog hu ua lub motherboard, tab sis tsis ncaj qha hu ua lub Circuit Court board.Txawm hais tias muaj cov kab hluav taws xob hauv lub motherboard, tab sis lawv tsis zoo ib yam, yog li ob qho tib si muaj feem cuam tshuam tab sis tsis tuaj yeem hais tau zoo ib yam thaum ntsuas kev lag luam.Lwm qhov piv txwv: vim tias muaj cov khoom sib xyaw ua ke ntawm lub rooj tsav xwm hauv Circuit Court, cov xov xwm tshaj tawm hu nws lub rooj tsav xwm IC, tab sis qhov tseeb nws tsis zoo ib yam li lub rooj tsav xwm luam tawm.Thaum peb feem ntau hais txog lub rooj tsav xwm luam tawm, peb txhais tau tias lub rooj tsavxwm liab qab - uas yog, lub rooj tsav xwm hauv Circuit Court uas tsis muaj cov khoom ntawm nws.

Kev faib tawm ntawm cov ntawv luam tawm Circuit Board

ib lub vaj huam sib luag
Ntawm qhov yooj yim tshaj plaws PCB, cov khoom yog concentrated ntawm ib sab thiab cov xov hlau yog concentrated rau sab nraud.Vim hais tias cov xov hlau tsuas yog tshwm sim ntawm ib sab, hom PCB no hu ua ib sab (Single-sided).Vim hais tias ib leeg-sab pawg thawj coj saib muaj ntau qhov kev txwv nruj ntawm kev tsim cov hlua hluav taws xob (vim tias tsuas muaj ib sab, thaiv tsis tuaj yeem hla thiab yuav tsum mus ncig ntawm txoj kev sib cais), tsuas yog cov khoom siv hluav taws xob thaum ntxov siv hom board.

Ob chav vaj huam sib luag
Lub rooj tsav xwm Circuit Court no muaj cov xov hlau ntawm ob sab, tab sis kom siv ob sab ntawm cov hlau, yuav tsum muaj kev sib txuas ntawm ob sab.Xws li "choj" ntawm circuits hu ua vias.Vias yog qhov me me ntawm PCB, ntim lossis pleev xim rau hauv cov hlau, uas tuaj yeem txuas nrog cov xov hlau ntawm ob sab.Vim tias thaj tsam ntawm lub rooj tsavxwm ob sab yog ob zaug loj dua li ntawm lub rooj tsavxwm ib leeg, lub rooj tsavxwm ob tog daws qhov nyuaj ntawm kev cuam tshuam cov xaim hauv lub rooj tsavxwm ib leeg (nws tuaj yeem dhau mus rau lwm qhov. sab los ntawm qhov ntawm qhov), thiab nws yog qhov tsim nyog rau kev siv ntau hauv circuits ntau dua li lub rooj tsav xwm ib leeg.
