Tseem muaj kev tsis sib haum xeeb txog kev faib tawm ntawm PCBs siv dav (cov ntawv luam tawm Circuit Board), tshwj xeeb tshaj yog tom qab lawv tau siv dav hauv ntau yam khoom siv hluav taws xob, txawm tias lawv tuaj yeem suav tias yog cov khoom siv hluav taws xob lossis cov khoom sib txuas.
Ua ntej, cia peb saib cov ntsiab lus ntawm semiconductors thiab kev sib xyaw ua ke. Semiconductors yog cov ntaub ntawv uas tuaj yeem tswj tau tam sim no nyob rau hauv ib qho chaw, xws li silicon, germanium, thiab lwm yam. Integrated circuits, ntawm qhov tod tes, integrate ntau yam khoom siv thiab circuits mus rau ib lub nti, ua kom nws ua tiav ntau yam hauv Circuit Court.
Yog li, PCB yog dab tsi? Los ntawm cov ntsiab lus txhais, PCB yog ib lub phaj zoo li cov khoom ua los ntawm cov khoom siv hluav taws xob, uas qee qhov circuits thiab lwm yam khoom siv tau tsim los ua kom muaj kev sib txuas hluav taws xob ntawm cov khoom siv hluav taws xob. Yog li, los ntawm kev txhais, PCB tsis tuaj yeem suav tias yog ib qho khoom siv hluav taws xob lossis kev sib koom ua ke.
Tab sis qhov no tsis txhais hais tias PCB tsis tseem ceeb. Qhov tseeb, PCB, raws li cov khoom siv hluav taws xob tseem ceeb, muab lub hauv paus tseem ceeb rau kev siv cov khoom siv hluav taws xob. Vim tias nws tuaj yeem tsis tsuas yog txuas ntau yam khoom siv hluav taws xob, tab sis kuj txhim kho txoj haujlwm thiab kev sib txuas ntawm cov khoom siv hauv Circuit Court tsim, thiab txais cov txheej txheem sib txawv thiab cov qauv tsim ntawm lub rooj tsav xwm Circuit Court kom ua tiav cov haujlwm sib txawv, yog li ua tiav cov ntawv thov sib txawv ntawm cov khoom siv hluav taws xob.
Kev txhim kho txuas ntxiv ntawm PCB thev naus laus zis. Los ntawm ib lub vaj huam sib luag mus rau ob sab thiab ntau txheej board daim ntaub ntawv, thiab tam sim no mus rau qib siab micro circuit boards, high-density interconnect boards, thiab lwm yam., daim ntawv thov ntau yam ntawm PCB tau dhau los ua qhov dav heev. Txawm tias nyob rau hauv qee qhov kev siv high-tech, kev tsim tshwj xeeb xws li cov kab hluav taws xob ceev thiab cov kab thaiv kev cuam tshuam tau tshwm sim los ua kom tau raws li cov kev xav tau ntau yam ntawm cov khoom siv hluav taws xob xws li nce kev kub ceev, siab precision, muaj peev xwm loj, thiab me me.
Yog li ntawd, txawm hais tias PCB tsis yog ib qho khoom siv hluav taws xob lossis kev sib koom ua ke, nws yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob. Kev txhim kho ntawm nws txoj haujlwm thiab kev txhim kho ntawm nws cov thev naus laus zis kuj tseem ua lub luag haujlwm tseem ceeb hauv kev txhim kho tag nrho cov khoom siv hluav taws xob. Qhov no kuj yog ib qho tseem ceeb uas peb yuav tsum tau ntsib thiab tsis tu ncua delve rau hauv kev tshawb fawb.
