Tus qauv pcb ib txwm tam sim no tsis pub tshaj 10a, tshwj xeeb hauv tsev neeg thiab cov khoom siv hluav taws xob, feem ntau yog kev ua haujlwm txuas ntxiv ntawm PCB tsis pub tshaj 2a.

Txawm li cas los xij, qee cov khoom lag luam yog tsim rau hluav taws xob hluav taws xob, thiab kev nruam tam sim no tuaj yeem ncav cuag li 80a. Xav txog qhov Instantaneous tam sim no thiab tawm ib lub npoo rau tag nrho cov kab ke, txuas ntxiv tam sim no ntawm lub zog xaim yuav tsum muaj peev xwm tiv taus ntau dua 100a.

Tom qab ntawd cov lus nug yog, dab tsi pcb tuaj yeem tiv taus tam sim no ntawm 100a?

Txoj kev 1: Layout ntawm PCB

Txhawm rau txiav txim siab tshaj-tam sim no muaj peev xwm ntawm PCB, peb thawj zaug pib nrog PCB cov qauv. Siv ob-txheej pcb ua piv txwv. Qhov no zoo ntawm Circuit Court board feem ntau muaj peb txheej txheej txheej txheem: tawv nqaij tooj liab, phaj, thiab tawv nqaij tawv. Cov tawv nqaij tooj liab yog txoj hauv kev uas tam sim no thiab teeb liab hauv PCB pass.

Raws li kev paub ntawm Tsev Kawm Ntawv Middle Bysics, peb tuaj yeem paub tias qhov kev tawm tsam ntawm ib qho khoom yog cuam tshuam nrog cov khoom siv, hla kev hla ntawm thaj chaw, thiab ntev. Txij li peb cov tam sim no sau ntawm cov tawv nqaij tooj liab, qhov tiv taus yog tsau. Qhov chaw hla kev hla tebchaws tuaj yeem raug suav tias yog qhov tuab ntawm cov tawv nqaij tooj liab, uas yog tooj liab tuab hauv cov PCB ua.

Feem ntau tooj liab tuab yog qhia tawm hauv OZ, tus tooj liab tuab ntawm 1 oz yog 35 um, 2 oz yog 70 teev, thiab lwm yam. Tom qab ntawd nws tuaj yeem yooj yim xaus lus tias thaum muaj qhov loj tam sim no yog yuav tsum tau dhau ntawm PCB, cov xaim yuav tsum luv thiab tuab, thiab cov ntawv sau zoo dua.

Ua tau, nyob rau hauv engineering, tsis muaj tus qauv nruj me ntsis rau kev siv hluav taws xob ntev. Feem ntau siv hauv kev tsim khoom: tooj liab thickness / kub sawv / cov ntsuas phoo no los ntsuas qhov peev xwm ntawm PCB.
