COF yog dab tsi, COB qauv hauv capacitive touch screen thiab resistive kov screen?

Chip on Board (COB) thiab Chip on Flex (COF) yog ob lub thev naus laus zis tshiab uas tau hloov pauv kev lag luam hluav taws xob, tshwj xeeb hauv thaj tsam ntawm microelectronics thiab miniaturization. Ob lub thev naus laus zis muab cov txiaj ntsig tshwj xeeb thiab tau pom ntau daim ntawv thov hauv ntau qhov kev lag luam, los ntawm cov neeg siv khoom siv hluav taws xob mus rau tsheb thiab kev kho mob.

Chip on Board (COB) thev naus laus zis suav nrog kev txhim kho cov pob zeb semiconductor ncaj qha mus rau hauv lub substrate, feem ntau yog cov ntawv luam tawm Circuit Board (PCB) lossis ceramic substrate, tsis tas siv cov ntim khoom ib txwm muaj. Txoj hauv kev no tshem tawm qhov xav tau ntawm cov ntim khoom loj, ua rau muaj kev sib txuam ntau dua thiab tsim qauv. COB kuj tseem muaj kev txhim kho thermal kev ua tau zoo, vim tias cov cua sov tsim los ntawm cov nti tuaj yeem ua kom tau zoo dua los ntawm cov substrate. Tsis tas li ntawd, COB thev naus laus zis tso cai rau kev sib koom ua ke ntau dua, ua rau cov neeg tsim khoom ntim ntau dua rau hauv qhov chaw me me.

Ib qho txiaj ntsig tseem ceeb ntawm COB thev naus laus zis yog nws cov txiaj ntsig zoo. Los ntawm kev tshem tawm qhov xav tau ntawm cov khoom ntim khoom thiab cov txheej txheem sib dhos, COB tuaj yeem txo tus nqi tag nrho ntawm kev tsim khoom siv hluav taws xob. Qhov no ua rau COB qhov kev xaiv zoo nkauj rau cov khoom ntim siab, qhov kev txuag nqi yog qhov tseem ceeb.

COB thev naus laus zis feem ntau yog siv rau hauv cov ntawv thov uas qhov chaw muaj tsawg, xws li hauv cov khoom siv txawb, LED teeb pom kev zoo, thiab cov khoom siv hluav taws xob hauv tsheb. Hauv cov ntawv thov no, qhov loj me me thiab muaj peev xwm sib koom ua ke siab ntawm COB thev naus laus zis ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ua tiav cov qauv me me, zoo dua.

Chip ntawm Flex (COF) thev naus laus zis, ntawm qhov tod tes, sib txuas cov kev hloov pauv ntawm cov txheej txheem hloov pauv nrog kev ua haujlwm siab ntawm cov khoom siv hluav taws xob liab qab. COF thev naus laus zis suav nrog kev txhim kho cov chips liab qab mus rau qhov hloov pauv tau yooj yim, xws li polyimide zaj duab xis, siv cov txheej txheem kev sib txuas siab. Qhov no tso cai rau kev tsim cov khoom siv hluav taws xob hloov tau yooj yim uas tuaj yeem khoov, twist, thiab ua raws li qhov chaw nkhaus.

Ib qho txiaj ntsig tseem ceeb ntawm COF thev naus laus zis yog nws qhov yooj yim. Tsis zoo li ib txwm nruj PCBs, uas txwv rau qhov chaw tiaj tus lossis nkhaus me ntsis, COF thev naus laus zis tuaj yeem tsim cov khoom siv hluav taws xob hloov tau yooj yim thiab txawm tias stretchable. Qhov no ua rau COF thev naus laus zis zoo rau cov ntawv thov uas yuav tsum tau ua kom yooj yim, xws li cov khoom siv hluav taws xob siv tau, hloov pauv tau, thiab cov khoom siv kho mob.

Lwm qhov zoo ntawm COF thev naus laus zis yog nws txoj kev ntseeg tau. Los ntawm kev tshem tawm qhov xav tau ntawm kev sib txuas ntawm cov xov hlau thiab lwm cov txheej txheem sib dhos ib txwm muaj, COF thev naus laus zis tuaj yeem txo qhov kev pheej hmoo ntawm kev ua haujlwm tsis zoo thiab txhim kho tag nrho cov kev ntseeg siab ntawm cov khoom siv hluav taws xob. Qhov no ua rau COF thev naus laus zis tshwj xeeb zoo rau cov ntawv thov uas muaj kev ntseeg siab yog qhov tseem ceeb, xws li hauv aerospace thiab automotive electronics.

Hauv kev xaus, Chip on Board (COB) thiab Chip on Flex (COF) thev naus laus zis yog ob txoj hauv kev tshiab rau kev ntim khoom siv hluav taws xob uas muaj qhov tshwj xeeb zoo dua li cov txheej txheem ntim khoom. COB thev naus laus zis ua rau cov qauv tsim qauv tsim nyog, tsim nyog nrog kev muaj peev xwm sib koom ua ke, ua rau nws zoo tagnrho rau kev siv qhov chaw txwv. COF thev naus laus zis, ntawm qhov tod tes, ua rau kev tsim cov khoom siv hluav taws xob hloov tau yooj yim thiab txhim khu kev qha, ua rau nws zoo tagnrho rau cov ntawv thov uas yooj yim thiab kev ntseeg siab yog qhov tseem ceeb. Raws li cov thev naus laus zis no txuas ntxiv mus, peb tuaj yeem cia siab tias yuav pom cov khoom siv hluav taws xob tshiab thiab zoo siab dua yav tom ntej.
