Qhov sib txawv ntawm ib leeg-ob tog plaub lub rooj zaum thiab ob tog sibrided Circuit Court yog tus naj npawb ntawm tooj liab txheej. Cov Nrov Kev Tshawb Fawb: Muab cov laug cam ob npaug rau ntawm ob sab ntawm cov Circuit Court Board, uas tuaj yeem txuas los ntawm kev tawm suab. Txawm li cas los xij, muaj tsuas yog ib txheej ntawm tooj liab nyob rau ib sab, uas tsuas tuaj yeem siv tau rau cov hluav taws xob yooj yim, thiab cov qhov ua tau tsuas yog siv rau kev sib txuas.

Cov kev xav tau kev ua haujlwm rau ob txoj kev sib tw sib xyaw ua ke yog qhov ua tuab sib txawv ua rau loj dua, thiab lub aperture ntawm lub ntsej muag me me thiab me dua. The quality of the metallized holes on which the layer-to-layer interconnection relies is directly related to the reliability of the printed board.

Nrog rau lub shrinking ntawm lub pore loj, cov khib nyiab uas tsis cuam tshuam rau cov tawv nqaij loj me me, ib zaug tsis muaj qhov ua tsis muaj qhov tsis tooj liab thiab ua qhov tsis tooj liab thiab ua qhov tsis tooj. Tus neeg tua neeg tuag ntawm Metallization.

Vuam txoj kev ntawm ob--sided Circuit Court board

Txhawm rau kom ntseeg tau tias cov nyhuv txhim khu kev qha ntawm cov kab ke sib txuas ntawm cov xov tooj sib txuas nrog cov xov tooj ntawm cov xov tooj ntawm cov hlau, qhov no yog kev npaj rau cov hlau ntawm lub rooj tsavxwm.

Cov khoom tseem ceeb ntawm ob-sided Circuit Circuit Board Vuam:
Rau cov khoom siv uas yuav tsum tau ua kom tiav, lawv yuav tsum tau ua raws li cov cai kos duab; uas yog, lawv yuav tsum ua thawj thiab ntsaws
Tom qab puab, tus qauv sab ntawm cov diode yuav tsum fim, thiab yuav tsum tsis muaj kev tsis sib xws nyob ntev ntawm ob pins.
Thaum muab cov khoom siv nrog polarity yuav tsum muaj, xyuam xim rau lawv cov polarity tsis tau thim rov qab. Tom qab ntxig, yob cov thaiv kev thaiv cov khoom sib xyaw, tsis muaj teeb meem nws yog kab rov tav lossis kab rov tav, yuav tsum muaj tsis pom tseeb.
Lub zog ntawm soldering hlau siv rau soldering yog nruab nrab ntawm 25 ~ 40w. Qhov ntsuas kub ntawm soldering hlau taub yuav tsum tau tswj ntawm li 242 ℃. Yog tias qhov ntsuas kub siab dhau, qhov taub yog yooj yim rau "tuag", thiab cov solded tsis tuaj yeem yaj thaum kub tsawg. Lub sijhawm soldering yuav tsum tau tswj tsis pub dhau 3 ~ 4 thib ob.
Cov vuam vuam feem ntau ua raws li kev siv vuam ntawm cov cuab yeej los ntawm luv rau siab thiab sab hauv. Lub sijhawm vuam yuav tsum tau kawm. Yog hais tias lub sijhawm ntev dhau, lub cuab yeej yuav raug hlawv, thiab tus tooj liab hauv kab ntawm lub tooj liab clad pawg yuav tseem yuav hlawv.
Vim tias nws yog ob sab seded soldering, txheej txheem txheej txheem lossis zoo li rau muab cov Circuit Court Board yuav tsum tau ua, yog li kom tsis txhob nyem cov khoom hauv qab.
Tom qab cov Circuit Court board yog soldered, ib qho kev kuaj mob hauv daim tshev yuav tsum tau nqa tawm kom paub qhov chaw uas ploj lawm ntxig thiab soldering. Tom qab kev pom zoo, txiav cov khoom siv ua dua tshiab thiab cov nyiam ntawm Circuit Courruit, thiab tom qab ntawd ntws mus rau cov txheej txheem tom ntej.
Hauv kev ua haujlwm tshwj xeeb, cov qauv txheej txheem cuam tshuam yuav tsum ua raws nraim kom ntseeg tau qhov zoo vuam zoo ntawm cov khoom lag luam.

Nrog rau kev txhim kho sai ntawm cov thev naus laus zis, khoom siv hluav taws xob uas muaj feem cuam tshuam nrog cov pej xeem tau hloov kho tas li. Cov pej xeem tseem xav tau cov khoom siv hluav taws xob nrog kev ua tau zoo, me me thiab ntau yam haujlwm, uas tso rau tom ntej cov kev xav tau ntawm cov laug cam. Qhov no yog vim li cas ob txoj kev sib koom ua ke ob tog plaub fab tau yug los. Vim tias qhov kev thov dav ntawm ob-kab plaub ntug Circuit Court, kev tsim cov ntawv luam tawm Circuit Court cov laug cam kuj tseem ua ntais hlau sib dua, nyias thiab me dua.
