PCB yog lub ntsiab lus uas koj tuaj yeem pom thaum tham txog cov khoom siv hluav taws xob lossis cov rooj sib tham hauv Circuit Court.Tab sis, koj puas tau xav paub tias daim ntawv tag nrho ntawm PCB yog dab tsi?Nyob rau hauv no blog, peb tsom kom nkag siab zoo dua qhov no acronym stands rau thiab nws txhais li cas nyob rau hauv lub ntiaj teb no ntawm electronics.
Printed Circuit Board yog dab tsi?
PCB sawv cev rau "Printed Circuit Board".Hauv cov ntsiab lus yooj yim, PCB yog lub rooj tsav xwm hluav taws xob ua los ntawm cov khoom siv tsis zoo nrog cov kab hluav taws xob txuas rau hauv nws.Cov kab no tsim kev sib txuas ntawm cov khoom siv hluav taws xob sib txawv thiab tso cai rau lub rooj tsavxwm ua haujlwm raws li lub voj voog ua tiav.PCBs yog siv nyob rau hauv ntau yam khoom siv hluav taws xob, los ntawm cov khoom ua si thiab cov khoom siv yooj yim mus rau cov cuab yeej kho mob thiab khoos phis tawj.
Qhov zoo ntawm PCB
PCBs muaj ntau qhov zoo dua li cov txheej txheem qub ntawm kev sib txuas cov khoom siv hluav taws xob.Ua ntej, lawv me me, ua rau lawv zoo tagnrho rau cov khoom siv hluav taws xob me me.Vim lawv qhov loj me, PCBs kuj sib dua thiab siv tau ntau dua li cov txheej txheem kev sib txuas.Qhov thib ob, txij li txoj kev coj mus rau hauv lub rooj tsavxwm, qhov kev pheej hmoo ntawm kev puas tsuaj los yog kev puas tsuaj raug txo qis heev.Qhov no ua rau PCBs txhim khu kev qha ntau dua li lwm cov kev xaiv.
Hom ntawm PCBs
Muaj ntau hom PCBs muaj, txhua tus muaj nws lub hom phiaj tshwj xeeb.Nov yog qee yam ntawm ntau hom:
1. Ib leeg-sided PCB yog hom yooj yim tshaj plaws, tag nrho cov kev coj ua yog nyob rau ntawm ib sab ntawm lub rooj tsavxwm.Cov no feem ntau siv hauv cov khoom siv yooj yim, nrog rau cov khoom ua si thiab cov khoom siv yooj yim.
2. Ob-sided PCBs muaj cov kab hluav taws xob ntawm ob sab ntawm lub rooj tsavxwm, tso cai rau kev sib txuas ntau dua.Txawm li cas los xij, lawv tseem yog qhov yooj yim piv rau lwm cov kev xaiv.
3. Multilayer PCBs muaj ntau txheej txheej ntawm cov txheej txheem kev coj ua, tso cai rau kev sib txuas ntau dua.Cov no feem ntau siv hauv cov khoom siv hluav taws xob ntau dua xws li khoos phis tawj thiab smartphones.
4. Rigid-Flex PCBs yog ib qho kev xaiv tshiab uas muab cov txiaj ntsig zoo ntawm cov tawv tawv thiab flex PCBs.Lawv yog cov zoo tagnrho rau siv nyob rau hauv cov khoom siv uas yuav tsum tau robust tsis tau saj zawg zog, xws li cov khoom siv kho mob.
nyob rau hauv xaus
Zuag qhia tag nrho, PCB yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob hauv ntiaj teb, muab txoj hauv kev txhim khu kev qha thiab muaj txiaj ntsig zoo los txuas cov khoom siv hluav taws xob.Lawv muaj ntau yam zoo dua li cov txheej txheem txuas ib txwm siv, suav nrog qhov me me, sib dua, thiab kev ntseeg siab dua.Paub txog daim ntawv tag nrho ntawm PCB thiab ntau hom muaj tuaj yeem pab koj nkag siab zoo txog lub luag haujlwm ntawm cov khoom siv hauv cov khoom siv hluav taws xob.
