3.Qhov kev txawj ntse --- PCB cov khoom qhia xaiv
Cov ntawv cog lus ntawm Circuit Court yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob. Xwb, cov acronym tseem tau lees paub rau cov ntawv ntim kab thaiv thiab cov ntawv luam kab uas luam, uas yog qhov tseem ceeb tshaj plaws. Vim yog lub luag haujlwm tseem ceeb ntawm cov laug cam no hauv txhua yam ntawm lub tshuab computer mus rau lub laij lej, cov khoom lag luam hauv PC yuav tsum tau ua tiav nrog kev tu thiab kev paub txog cov khoom siv hluav taws xob ntawm cov khoom siv.
Ua ntej txoj kev loj hlob ntawm PCB, cov ntaub ntawv ntawm lub rooj sib tham ntawm thaj chaw muaj feem ntau los ntawm cov zes ntawm cov pob zeb, cov hlua khauj khaum uas yooj yim heev uas ua rau qeeb tsis tau. Lawv tseem muaj peev xwm luv luv thaum muaj hnub nyoog tau tuav thiab qee qhov xov hlau pib tawg. Raws li tau pom zoo, cov txheej txheem kev ua haujlwm uas nkag mus rau hauv qhov thaiv ntawm cov laug cam no yog ruam thiab mob siab.
Raws li kev nce qib ntau ntawm cov khoom hluav taws txhua hnub pib vam khom rau ntawm Circuit Board boards, cov haiv neeg yog tsim los tsim cov yooj yim, muaj ntau txoj kev zoo, thiab qhov no coj mus rau kev tsim cov khoom, PCB. Nrog PCB cov ntaub ntawv, circuits tuaj yeem taug kev ntawm ib lub party ntawm ntau yam. Cov hlau uas tswj cov kev hloov ntawm cov thawj coj ntawm lub rooj tsavxwm thiab lwm cov khoom txuas nrog lub kauj vev xaib, uas yog siv ob lub hom phiaj nrog nws cov khoom zoo.
PCB Cov Khoom Txheej Txheem
Feem ntau cov PCB muaj plaub txheej, uas yog cov cua sov laminated ua ke rau hauv ib txheej.
Cov khoom siv hauv PCB los ntawm sab saum toj mus rau hauv qab yog Silkscreen, Soldermask, Copper thiab Substrate .
Qhov kawg ntawm cov txheej, substrate, yog ua los ntawm fiberglass thiab tseem raug hu ua FR4, nrog rau cov ntawv FR uas sawv rau "hluav taws kub retardant." Cov txheej txheem substrate no muab lub hauv paus ruaj khov rau PCBs, tab sis yog qhov sib txawv nyias txawv nyias raws li kev siv ntawm lub rooj tsavxwm.
Ib qho pheej yig dua ntawm cov laug cam kuj muaj nyob rau hauv kev lag luam uas tsis siv cov lus qhia hauv PCB tib yam, tab sis zoo li muaj cov phenolics lossis epoxies. Vim lub thermal rhiab heev ntawm cov laug cam, lawv yuav poob lawv lamination tau yooj yim. Cov cheaper boards no feem ntau yooj yim los txheeb xyuas los ntawm qhov tsis hnov tsw lawv muab tawm thaum ua cov laug.
PCB ob txheej yog tooj liab, uas yog laminated mus rau lub substrate nrog ib tug sib tov ntawm tshav kub thiab nplaum. Lub khob tooj liab yog nyias, thiab ntawm ib co kab muaj ob yam xws li cov khaubncaws sab nraud povtseg - ib qho saum toj thiab ib qho qis dua hauv substrate. PCBs nrog tsuas yog ib txheej ntawm tooj yog siv rau cov nqi hluav taws xob pheej yig dua.
Siv qhov sib txuam ua siv tooj liab (laminate) (CCL) uas muaj peev xwm siv tau los ua ntau hom raws li cov qauv kev sib txawv uas muaj xws li cov khoom siv, siv cov ntaub nplaum, qhov hluav taws, CCL kev ua tau zoo. Qhov kev qhia luv luv ntawm CCL yog muaj nyob rau hauv qab rooj.

Tshaj siab ntawm cov muag zaub ntsuab yog txheej txheej silkscreen, uas ntxiv cov tsiaj ntawv thiab cov cim qhia ua zauv uas ua kom PCB nyeem tau cov tshuab hlwb hlau. Qhov no, tig mus, nws yooj yim dua rau cov khoom siv hluav taws xob kom muab txhua qhov PCB tso rau hauv qhov chaw zoo thiab nyob rau sab xis ntawm txhua feem. Cov txheej txheem silkscreen feem ntau yog dawb, txawm xim xws li xim liab, daj, grey thiab dub kuj qee zaum siv.
