Thaum lub sij hawm tsim khoom, ua ntej- kev tsim khoom yog qhov tseem ceeb los tiv thaiv qhov tsis tshua muaj txiaj ntsig los ntawm kev qhib luv luv, txo qis qhov xav tau ntawm cov khoom seem FPC thiab yuav tsum tau rov ua dua -cov khoom lag luam vim muaj teeb meem kev ua haujlwm tsis zoo xws li drilling, dov, thiab txiav, thiab ntsuas qhov kev xaiv cov khoom zoo tshaj plaws rau kev ua tiav cov txiaj ntsig zoo tshaj plaws rau cov neeg siv khoom.
Ua ntej- kev tsim khoom tsim muaj peb yam tseem ceeb, txhua yam yog ua los ntawm engineers. Ua ntej, FPC board engineering kev ntsuam xyuas ntsuas tus neeg siv khoom lub peev xwm los tsim lub rooj tsavxwm, seb lub tuam txhab muaj peev xwm ua tau raws li cov neeg siv khoom xav tau, thiab chav tsev nqi. Yog tias qhov kev ntsuam xyuas engineering dhau mus, kev npaj cov ntaub ntawv yuav pib tam sim kom ntseeg tau tias cov khoom siv raw rau txhua theem ntawm kev tsim khoom. Thaum kawg, engineers ua cov neeg siv khoom cov ntaub ntawv engineering, suav nrog CAD cov qauv kos duab thiab Gerber circuit cov ntaub ntawv, kom ntseeg tau tias lawv sib haum nrog cov khoom tsim khoom tsim khoom thiab cov lus qhia tshwj xeeb. Kev tsim cov duab kos thiab MI (daim ntawv teev cov txheej txheem engineering) yog tom qab ntawd muab faib rau lub tuam tsev tsim khoom, tswj cov ntaub ntawv, kev yuav khoom, thiab lwm lub tuam tsev, tso cai rau cov txheej txheem ntau lawm pib.
