Koj puas xav tau txhawm rau txhawm rau txhawm rau tiv thaiv PCB uas twb tau ua tiav lawm, lossis xav kho qhov tawg tawg lossis txawm tias hloov pauv qee yam zoo li tus tswj kev ua si? Zoo ntawm no yog li cas!
Kauj ruam 1: Cov khoom siv
Koj yuav tsis xav tau ntau rau cov lus qhia no, tsuas yog cov hauv paus koj yuav xav tau: 1. Muaj peev xwm ua kom yaj (Kuv paub tseeb tias koj twb paub lawm los ntawm kev paub) 2. Ib lub raj hlau (cov lus me me, nws yooj yim dua rau cov kab me me!) 3. Tub Rog 4. Ib qho PCB lossis ib yam dab tsi nrog kab 5. Ib yam dab tsi los txhuam cov kab nrog (rab riam los yog ntswj ntswj lossis lwm yam nyias). Ib yam dab tsi los txhawm rau kab ntawv (Tsis teb los tau) 7. Pab tes tuav lub rooj sib tham hauv Circuit Court (Tsis teb los tau) 8. FluxDifficulty: Yooj yim heev
Kauj ruam 2: Xaiv thiab khawb
Tam sim no xaiv thaj chaw uas koj xav kom muab tshuaj txhuam thiab txhuam! Koj yuav pom tias koj tsis tuaj yeem tso ncaj qha rau ntawm kab. Muaj txheej txheej yas me me thiab txheej txheej txheej txheej polymer tiv thaiv (cov khoom ntsuab) npog cov kab ntawm tooj liab. Peb lub hom phiaj ntawm no yog tshem tag nrho cov khoom pov tseg yog li peb tuaj yeem nkag mus rau qee yam uas cov laug yuav txuas rau, tooj liab!
Kauj ruam 3: Npaj
Tam sim no ua ntej koj ua ib yam dab tsi rau ntawm PCB, koj yuav tsum npaj koj cov khoom/xov hlau. Koj yuav tsum tso dab ntawm cov kab laug sab rau ntawm koj cov xaim lossis cov khoom siv siv flux thiab npog qhov qhia tooj liab nrog cov kab laug sab. Yog tias koj tsis muaj flux, koj tseem tuaj yeem npog koj lub xov hlau (braided xaim feem ntau ua haujlwm zoo tshaj plaws). Qhov no yuav ua tej yam yooj yim dua.
Kauj ruam 4: Cov laug
Tam sim no mus tom ntej thiab muab tshuaj txhuam koj cov tivthaiv/xaim mus rau PCB. Hint: Yog tias koj siv cov kab laug sab mus rau ib txoj kab me me, koj yuav xav ntxiv dab dab kub kua nplaum los khaws cov khoom tiv thaiv nyob hauv qhov chaw (Kuv tau siv cov kab tshwj xeeb tshwj xeeb rau qhov piv txwv.)
Kauj ruam 5: Piv txwv
Lub peev xwm los txhawm rau txhawm rau taug qab tuaj yeem muaj txiaj ntsig zoo hauv kev kho thiab hloov kho. Hauv cov duab koj tuaj yeem pom tias kuv "kho" cov kab tawg thiab ntxiv ib feem rau hauv kab. Kuv vam tias koj nyiam kuv Cov Lus Qhia!

Muaj ntau txoj haujlwm zoo li no, tab sis feem ntau xav tau kev sib txuas thiab kev sib txuas. Cov ntawd yog qhov zoo, tab sis kuv
