Cov khoom sib txuas yog qhov tseem ceeb, cov khoom tseem ceeb hauv cov khoom siv hluav taws xob; lawv lub luag haujlwm tseem ceeb yog los pab txhawb kev sib kis tau zoo ntawm lub zog lossis cov teeb liab thiab kev sib cuam tshuam ntawm circuits los ntawm kev sib cuag ntawm lub cev.
Txoj kev tam sim no thiab teeb liab kis tau tus mob: Tsim kom muaj kev ruaj ntseg hluav taws xob sib txuas ntawm ob qho khoom siv sib cais, Circuit Court boards, los yog cables, ua rau qis - poob pauv hluav taws xob thiab cov ntaub ntawv / cov teeb liab.
Separability thiab Modularity: Txhawb kev sib raug zoo sai thiab tsis sib haum xeeb, ua kom yooj yim rau kev sib dhos ntawm cov cuab yeej, hloov cov khoom tsis raug, thiab kev hloov kho lossis kev saib xyuas yam tsis tas yuav muaj kev sib txuas mus tas li.
Ib puag ncig kev sib cais thiab kev tiv thaiv: Siv cov insulators thiab sealing lug cais cov kev sib cuag, tiv thaiv kev sib cuag tsis ua hauj lwm los ntawm luv luv circuits, corrosion, los yog kev co, yog li ua kom ruaj khov system ua hauj lwm nyob rau hauv hnyav ib puag ncig.
