Qhov sib txawv ntawm ib leeg-sab Circuit Court boards thiab ob-sided circuit boards yog cov tooj liab txheej. Nrov kev tshawb fawb: ob-sided circuit boards muaj tooj liab ntawm ob sab ntawm lub rooj tsav xwm Circuit Court, uas tuaj yeem txuas tau los ntawm vias. Txawm li cas los xij, tsuas muaj ib txheej tooj liab ntawm ib sab, uas tsuas yog siv tau rau cov kab hluav taws xob yooj yim xwb, thiab cov qhov ua tau tsuas yog siv rau kev sib txuas hauv plug-in.

Cov txheej txheem kev cai rau ob-sided Circuit Court boards yog hais tias cov xov hlau ceev yuav loj dua, lub aperture yog me me, thiab lub aperture ntawm lub metallized qhov yuav me thiab me. Qhov zoo ntawm cov metallized qhov uas cov txheej txheem-rau-txheej interconnection relies yog ncaj qha ntsig txog kev ntseeg siab ntawm cov ntawv luam tawm.

Nrog rau qhov me me ntawm qhov pore me me, cov khib nyiab uas tsis cuam tshuam rau qhov loj pore loj, xws li txhuam cov khib nyiab thiab volcanic tshauv, ib zaug tso rau hauv lub qhov me me yuav ua rau cov electroless tooj liab thiab electroplating poob nws cov nyhuv, thiab yuav muaj qhov. tsis muaj tooj liab thiab ua qhov. Tus tua neeg tuag ntawm metallization.

Vuam txoj kev ntawm ob-sided Circuit Court board

Txhawm rau kom ntseeg tau qhov kev ntseeg tau zoo ntawm lub rooj tsav xwm ob tog, nws raug nquahu kom welding qhov txuas ntawm ob sab board nrog cov xov hlau lossis cov zoo li (uas yog, dhau ntawm qhov ntawm cov txheej txheem metallization), thiab txiav tawm lub protruding ib feem ntawm kev sib txuas kab Kev raug mob ntawm tus neeg teb xov tooj tes, qhov no yog qhov kev npaj rau kev xaim ntawm lub rooj tsavxwm.

Qhov tseem ceeb ntawm ob-sided circuit board vuam:
Rau cov khoom siv uas xav tau kev tsim kho, lawv yuav tsum tau ua tiav raws li qhov yuav tsum tau ua ntawm cov txheej txheem kos duab; uas yog, lawv yuav tsum tau zoo li tus thawj thiab plug-in
Tom qab shaping, tus qauv sab ntawm lub diode yuav tsum fim, thiab yuav tsum tsis txhob muaj qhov sib txawv ntawm qhov ntev ntawm ob tus pins.
Thaum tso cov khoom siv nrog cov kev xav tau polarity, xyuam xim rau lawv cov polarity tsis txhob thim rov qab. Tom qab ntxig, yob cov khoom thaiv kev sib xyaw ua ke, txawm tias nws yog cov cuab yeej ntsug lossis kab rov tav, yuav tsum tsis muaj qhov pom tseeb qaij.
Lub zog ntawm cov hlau uas siv rau kev sib tsoo yog nyob nruab nrab ntawm 25 ~ 40W. Qhov kub ntawm cov hlau taub hau yuav tsum tau tswj ntawm li 242 ℃. Yog hais tias qhov kub thiab txias heev, lub hau yog yooj yim "tuag", thiab lub solder tsis tuaj yeem yaj thaum qhov kub thiab txias. Lub sij hawm soldering yuav tsum tau tswj tsis pub dhau 3 ~ 4 thib ob.
Txoj kev vuam yog feem ntau ua raws li txoj cai vuam ntawm lub cuab yeej los ntawm luv mus rau siab thiab los ntawm sab hauv tawm. Lub sijhawm vuam yuav tsum tau ua tiav. Yog tias lub sij hawm ntev dhau lawm, cov cuab yeej yuav raug hlawv, thiab cov kab tooj liab ntawm cov tooj liab clad board kuj yuav hlawv.
Vim hais tias nws yog ob-sided soldering, ib txheej txheej txheem los yog cov zoo li rau muab lub Circuit Court board kuj yuav tsum tau ua, thiaj li tsis mus nyem cov khoom hauv qab.
Tom qab lub Circuit Court board yog soldered, yuav tsum tau nqa tawm ib tug tag nrho check-nyob rau hauv daim tshev yuav tsum tau nqa tawm kom paub seb qhov twg tsis muaj insertion thiab soldering. Tom qab kev pom zoo, luas cov khoom siv rov ua dua pins thiab cov zoo li ntawm lub rooj tsav xwm Circuit Court, thiab tom qab ntawd ntws mus rau cov txheej txheem tom ntej.
Hauv kev ua haujlwm tshwj xeeb, cov txheej txheem tsim nyog yuav tsum tau ua raws li nruj me ntsis kom ntseeg tau tias cov khoom siv vuam zoo.

Nrog rau txoj kev loj hlob sai ntawm kev siv tshuab siab, cov khoom siv hluav taws xob uas muaj feem xyuam nrog rau cov pej xeem tau raug hloov kho tas li. Cov pej xeem kuj xav tau cov khoom siv hluav taws xob nrog kev ua haujlwm siab, me me thiab ntau lub zog, uas tso cov kev xav tau tshiab ntawm cov rooj sib tham. Qhov no yog vim li cas lub rooj tsavxwm ob tog tau yug los. Vim yog daim ntawv thov dav ntawm ob tog vaj huam sib luag, kev tsim cov ntawv luam tawm Circuit Court boards kuj dhau los ua sib dua, nyias, luv thiab me dua.
