Raws li tus tsim kho vajtse, txoj haujlwm yog los tsim PCBs raws sijhawm thiab nyob rau hauv pob nyiaj siv, thiab lawv yuav tsum muaj peev xwm ua haujlwm ib txwm! Hauv tsab xov xwm no, kuv yuav piav qhia yuav ua li cas los txiav txim siab txog kev tsim cov teeb meem ntawm lub rooj tsav xwm hauv Circuit Court hauv kev tsim, kom tus nqi ntawm lub rooj tsav xwm Circuit Court qis dua yam tsis muaj kev cuam tshuam rau kev ua haujlwm. Thov nco ntsoov tias ntau cov txheej txheem hauv qab no yuav tsis ua raws li koj cov kev xav tau tiag tiag, tab sis yog tias muaj xwm txheej tso cai, lawv yog txoj hauv kev zoo los txo cov nqi.
Khaws tag nrho cov khoom siv saum npoo av (SMT) ntawm ib sab ntawm lub rooj tsavxwm
Yog tias muaj chaw txaus, tag nrho cov khoom SMT tuaj yeem muab tso rau ntawm ib sab ntawm lub rooj tsavxwm. Nyob rau hauv txoj kev no, lub rooj tsav xwm Circuit Court tsuas yog xav tau los ntawm SMT kev tsim khoom ib zaug. Yog hais tias muaj cov khoom ntawm ob sab ntawm lub rooj tsav xwm Circuit Court, nws yuav tsum mus dhau ob zaug. Los ntawm kev tshem tawm qhov thib ob SMT khiav, kev tsim lub sijhawm thiab tus nqi tuaj yeem txuag tau.
Xaiv qhov chaw uas yooj yim los hloov
Thaum xaiv cov khoom, xaiv cov khoom uas yooj yim hloov. Txawm hais tias qhov no yuav tsis txuag cov nqi tsim khoom tiag tiag, txawm tias cov khoom hloov pauv tau tawm ntawm cov khoom lag luam, tsis tas yuav rov tsim kho thiab rov tsim kho lub rooj tsav xwm. Raws li cov engineers feem ntau paub, nws yog qhov zoo tshaj plaws rau txhua tus kom tsis txhob rov tsim dua!
Nov yog qee cov lus qhia rau xaiv qhov yooj yim hloov qhov chaw:
Xaiv qhov chaw nrog qhov ntev raws li tus qauv kom tsis txhob xav tau hloov tus qauv tsim txhua zaus qhov tsis siv lawm. Yog tias cov khoom hloov pauv muaj cov hneev taw tib yam, koj tsuas yog yuav tsum tau hloov qhov tshiab kom tiav!
Ua ntej xaiv cov khoom, thov mus saib qee qhov chaw tsim khoom lub vev xaib kom pom tias muaj cov khoom siv tau cim tias "tso tseg" lossis "tsis pom zoo rau cov qauv tshiab." ib
Xaiv cov khoom uas muaj qhov loj ntawm 0402 lossis loj dua
Xaiv cov khoom me me yuav txuag tau qhov chaw muaj txiaj ntsig zoo, tab sis qhov kev xaiv tsim no muaj qhov tsis zoo. Lawv xav tau sijhawm thiab siv zog ntau dua kom muab tso rau thiab muab tso kom raug. Qhov no ua rau cov nqi tsim khoom ntau dua.
Nws zoo li tus archer uas tua ib tug xub ntawm lub hom phiaj uas dav 10 feet thiab tuaj yeem ntaus nws yam tsis tas yuav mloog ntau dhau. Archers tuaj yeem tua tsis tu ncua yam tsis siv sijhawm thiab lub zog ntau dhau. Txawm li cas los xij, yog tias koj lub hom phiaj raug txo qis rau 6 ntiv tes xwb, ces tus archer yuav tsum mloog zoo thiab siv sijhawm qee lub sijhawm txhawm rau txhawm rau ntaus lub hom phiaj kom raug. Yog li ntawd, qhov chaw me dua 0402 yuav tsum tau siv sij hawm ntau thiab siv zog ua kom tiav qhov kev teeb tsa, uas txhais tau hais tias tus nqi yuav siab dua.
Nkag siab thiab ua raws li cov qauv tsim khoom
Ua raws li cov qauv muab los ntawm cov chaw tsim khoom. Yuav khaws tus nqi qis. Cov haujlwm nyuaj feem ntau raug nqi ntau dua los tsim khoom.
Thaum tsim ib qhov project, koj yuav tsum paub cov hauv qab no:
Siv cov txheej txheem txheej txheem nrog cov ntaub ntawv txheem.
Sim siv 2-4 txheej PCB.
Khaws qhov tsawg kawg nkaus kab / qhov sib nrug ntawm qhov sib txawv ntawm tus qauv.
Tsis txhob ntxiv cov kev cai tshwj xeeb kom ntau li ntau tau.
