PCB ib nrab qhov board yog ib hom tshwj xeeb ntawm cov ntawv luam tawm Circuit Board uas muaj cov yam ntxwv ntawm ib nrab perforation. Nquag, perforations ntawm cov ntawv luam tawm zoo tib yam yog tsim los ntawm qhov, thaum ib nrab lub qhov rooj yog drilled rau ntawm ib sab kom sab nraud ntawm lub rooj tsav xwm ncaj nraim.
PCB ib nrab qhov boards muaj ntau yam kev siv hauv kev tsim khoom siv hluav taws xob.
Ua ntej, ib nrab lub qhov rooj tuaj yeem muab kev sib txuas zoo dua ntawm kev sib txuas.
Vim yog qhov tsim ntawm lub rooj tsavxwm ib nrab ntawm lub qhov rooj, cov khoom siv ntawm lub rooj tsavxwm Circuit Court tuaj yeem ruaj khov rau ntawm lub rooj tsavxwm, txo qhov kev pheej hmoo ntawm kev xoob thiab kev cuam tshuam ntawm cov khoom. Qhov no yog qhov tseem ceeb rau kev ruaj ntseg thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob.
Qhov thib ob, ib nrab lub phaj tuaj yeem txhim kho cov cua sov dissipation ntawm cov khoom siv hluav taws xob.
Los ntawm kev txhim kho lub dab dej kub los yog thermal ncoo rau ntawm ib nrab lub qhov phaj, cov cua sov uas tsim los ntawm cov khoom siv hluav taws xob tuaj yeem xa mus rau sab nraud ntawm lub phaj thiab dissipated los ntawm lub dab dej kub. Qhov no tuaj yeem tiv thaiv cov khoom siv hluav taws xob los ntawm kev cuam tshuam los ntawm overheating thiab txuas lawv lub neej kev pab cuam.
Tsis tas li ntawd, ib nrab qhov boards kuj tuaj yeem ua tiav qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.
Vim lub fact tias ib nrab qhov board tsuas yog drilled rau ntawm ib sab thiab khaws cia nyob rau hauv lub tiaj tus, ntau yam yuav tsum tau teem rau ntawm lub tiaj tus, ua kom tiav ib tug compact layout ntawm lub Circuit Court board. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov khoom siv hluav taws xob nrog cov kev xav tau me me, vim nws tuaj yeem txuag tau qhov chaw zoo.
