1: Lub hauv paus rau kev xaiv qhov dav ntawm cov ntawv luam tawm hlau: qhov tsawg kawg nkaus ntawm cov xov hlau loj heev, thiab cuam tshuam rau cov kev ua tau zoo ntawm Circuit Court. Txoj kab dav dav heev, cov thaning ceev tsis yog siab, cov chaw zov menyuam nce, ntxiv rau kev nce qib, nws tsis muaj txiaj ntsig zoo rau kev miniaturization. Yog tias cov load tam sim no suav nrog 20a / mm2, thaum lub tuab ntawm tooj liab clad yog 1-254 hli (40-14 mil) tuaj yeem ua tau raws li cov cai thov. Lub hauv av hlau thiab muab hluav taws xob rau ntawm cov khoom siv hluav taws xob siab tuaj yeem tsim kev nce ntxiv raws li lub zog loj. Ntawm lub zog hluav taws xob tsawg Digital Cov Hluav Taws Xob, txhawm rau txhawm rau txhim kho cov cua sov, qhov kev dav tsawg kawg yog kev noj 0.254-1.27mm (10-15mil). Hauv tib lub Circuit Court Board, lub zog qaum. Lub av xaim yog tuab dua li lub teeb liab hlau.
2: LINE TAWM: Thaum nws yog 1.5mm (txog 60 mil), lub voltage ntawm cov kab yog ntau tshaj 200v), tus kab spacting yog coj raws li 1.0-1.5 hli (40-60 Mil). Hauv cov tshuab hluav taws xob tsawg, xws li cov tshuab hluav taws xob digital, nws tsis tsim nyog los xav txog qhov kev sib tw tawg, cov txheej txheem ntau lawm tso cai, tuaj yeem yog qhov me me.
3: Ncoo: rau 1 / 8w resistor, lub qhov taub txhuas txhuas yog 32/2 W, qhov kev txo qis heev, ua rau muaj kev txo qis hauv cov ntaub qhwv. Nws yog ib qho yooj yim uas poob tawm, lub qhov txhuas me me dhau, thiab cov khoom sib xyaw yog qhov nyuaj.
4: Kos cov Circuit Court: Qhov kev ncua deb ntawm ciam teb kab thiab cov pad tivthaiv tus nqi tsis tuaj yeem ua tsis tau zoo dua) tsis yog, nws yog qhov nyuaj rau txiav cov khoom.
5: Lub hauv paus ntsiab lus ntawm cov txheej txheem sib xyaw: A: Cov qauv tsim dav dav: Hauv PCB tsim, yog tias muaj ob txoj kab sib tw digital thiab analog circuit rau hauv Circuit System. Raws li zoo li cov voj voog siab tam sim no, lawv yuav tsum muab tso tawm cais kom txo qis ntawm cov tshuab. Nyob rau tib hom hluav taws xob, cov khoom siv tau muab tso rau hauv cov block thiab faib raws li cov teeb liab ntws ntws thiab muaj nuj nqi.
6: Cov cim kev ntsuas teeb tsa, cov zis teeb liab tsav tsav yuav tsum tau nyob ze rau cov kab ke ntawm cov kab ke nrog luv, txhawm rau txo cov kev cuam tshuam ntawm cov tswv yim thiab tso zis.
7: Cheebtsam muab tso rau qhov chaw: Cheebtsam tsuas yog npaj rau hauv ob qho lus qhia, kab rov tav thiab ntsug. Txwv tsis pub, txwv tsis pub siv.
8: Kev Txhaum. Rau nruab nrab ceev cov laug cam, qhov kev sib tw ntawm cov khoom sib xyaw me xws li cov khoom siv me me, kev txiav txim siab, thiab lwm cov txheej txheem txiav txim siab muaj feem xyuam rau cov plug-hauv thiab vuam txheej txheem. Thaum lub sijhawm yoj soldering, cov khoom sib xyaw ua ke tuaj yeem 50-100mil (1.27-254mm). Loj dua, xws li noj 100mil, sib xyaw Circuit Court Chip, tivthaiv qhov kev sib cav feem ntau 100-150mil.
9: Thaum muaj tej yam muaj peev xwm sib txawv ntawm cov khoom sib txawv yog qhov loj, qhov sib nrug ntawm cov cheebtsam yuav tsum muaj qhov loj me kom tiv thaiv kev tshem tawm.
10: Hauv IC, lub capouspling capacitor yuav tsum yog ze rau lub zog hluav taws xob hauv av tus lej ntawm lub nti. Txwv tsis pub, cov nyhuv lim cov nyhuv yuav hnyav dua. Hauv cov kev sib tw digital, txhawm rau kom ntseeg tau tias cov kev ua haujlwm ntawm cov tshuab digital, IC decoubling capacitors tau muab tso rau ntawm lub zog hluav taws xob thiab hauv av ntawm txhua Circuit Court sib xyaw Circuit Court. Decoupling capacitors feem ntau siv ceramic chip capacitors nrog lub peev xwm ntawm 0.01 ~ 0.1 UF. Kev xaiv ntawm decoupling caport muaj peev xwm feem ntau yog raws li qhov kev ua haujlwm ntawm lub cev thiab cov khoom siv fais fab
11: Lub teev sib xyaw ua ke sib xyaw yuav tsum tau ze li sai tau rau lub moos teeb liab plock ntawm ib nti microcomputer nti kom txo tau cov kev sib txuas ntev ntawm moos Circuit Court. Thiab nws yog qhov zoo tshaj plaws tsis txhob khiav cov hlau hauv qab no.
