Raws li ib qho tseem ceeb thiab tseem ceeb ntawm cov khoom siv hluav taws xob, PCB boards (circuit boards) tau ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob niaj hnub no. Lawv tau siv dav hauv kev lag luam xws li xov tooj, khoos phis tawj, TV, mobile devices, thiab automotive electronics|
Muaj ntau ntau hom PCB boards, ntawm cov uas feem ntau yog liab qab PCB boards. Yog li ntawd, dab tsi yog ib tug liab qab PCB board? Yooj yim muab, nws yog aPCB pawg thawj coj saibuas tsis tau ua tiav cov kauj ruam xws li tshuaj etching, drilling, thiab kho qhov chaw zoo. Qhov sib txawv loj tshaj plaws ntawm nws thiab lub rooj tsavxwm tiav yog tias nws tsis tau raug soldered lossis sib dhos.
Dab tsi yog qhov zoo ntawm liab qab PCB boards? Ua ntej, nws ua rau cov neeg tsim qauv sim ntsuas cov khoom siv hluav taws xob thiab sim cov tswv yim tshiab ntawm tus nqi qis heev, thaum lub Circuit Court yog lawm, ces hloov nws mus rau lub rooj tsavxwm tiav rau kev sib dhos thiab sib dhos. Qhov thib ob, thaum cov pej xeem version PCB tsis tuaj yeem ua tau raws li cov qauv tsim, cov laug cam PCB tuaj yeem siv rau kev tsim khoom tus kheej, uas kuj yog vim li cas DIY electronics enthusiasts dav siv liab qab PCB boards.
Tau kawg, kuj tseem muaj qee qhov tsis zoo rau kev siv cov laug cam PCB. Ua ntej, txawm tias cov neeg tsim khoom zoo tshaj plaws pom tias nws nyuaj rau kev lees paub tag nrho qhov zoo thiab kev ruaj ntseg ntawm cov qauv tsim tawm, yog li yuav tsum tau kuaj xyuas kom ntxaws thiab tshuaj xyuas. Thib ob, rau kev tsim khoom me me thiab kev siv tus kheej, siv cov laug cam PCB tuaj yeem txuag tau tus nqi ntau dua, tab sis rau kev tsim khoom loj, tus nqi ntawm kev ua cov laug cam yuav dhau los ua qhov siab.
