1. Dab tsi yog cob mos pob
Ua tib zoo saib xyuas cov netizens yuav pom tias muaj dub tshaj ntawm qee qhov Circuit Court boards, yog li dab tsi yog dab tsi no? Vim li cas nws nyob ntawm Circuit Court Board? Cov nyhuv yog dab tsi? Qhov tseeb, qhov no yog hom pob. Peb feem ntau hu nws "pob mos". Nws tau hais tias pob muag muag yog qhov tseeb "nyuaj", thiab nws cov khoom siv ua haujlwm yog epoxy cob qhia. , Peb feem ntau pom tias kev tau txais lub ntiaj teb tau txais lub taub hau kuj yog ntawm cov khoom no, thiab cov nti IC yog sab hauv nws. Cov txheej txheem no yog hu ua "kev sib raug zoo", thiab peb feem ntau hu nws "khi".
Qhov no yog cov txheej txheem sib txuas hlau hauv cov txheej txheem ntau lawm. Nws lub npe Askiv yog cob (nti ntawm Board), uas yog, nti rau ntawm Board ntim. Qhov no yog ib qho ntawm cov nuj nqis liab qab mounting technologies. Lub nti tau txuas nrog epoxy cob qhia. Mounted ntawm PCB luam tawm cov boardcuital board, tom qab ntawd vim li cas qee cov pob zeb hluav taws xob tsis muaj cov yam ntxwv zoo li no, thiab cov yam ntxwv zoo li cas ntawm hom pob no?
2. Cov yam ntxwv ntawm COB muag pob
Cov thev naus laus zis ntim khoom siv feem ntau yog rau tus nqi. Raws li qhov yooj yim tshaj tawm nti nti mounting, thiaj li tiv thaiv lub hauv paus IC los ntawm kev puas tsuaj, feem ntau muab tso rau ntawm cov tooj liab ntawv ntawm cov Circuit Co Board. Nws yog puag ncig thiab xim yog xim dub. Qhov kev siv tshuab ntim tau muaj qhov zoo ntawm tus nqi qis, qhov chaw txuag, lub teeb thiab nyias, ntim cov khoom siv cua sov. Ntau ntau qhov kev sib xyaw ua ke, tshwj xeeb tshaj yog cov nqi qis tshaj plaws, tsuas yog yuav tsum tau muab tso rau hauv hom no. Lub Circuit Coip yog coj tawm nrog ntau cov hlau hlau, thiab tom qab ntawd nqa mus rau cov caccuit Court board, cam khwb cia siv cov kua nplaum kom khov thiab tawv.
3. Daim Ntawv Thov Sijhawm
Vim tias hom pob no nws muaj nws tus kheej cov yam ntxwv cuam tshuam, nws tseem siv rau hauv cov khoom siv hluav taws xob hluav taws xob, xws li cov koob yees duab hluav taws xob, thiab lwm yam, thiab lwm yam, thiab lwm yam.
Qhov tseeb, cob cov ntim muag muag tsuas yog tsis tsuas yog txwv rau cov chips, xws li cob teeb ua ke, uas yog kev sib xyaw nrog daim iav hlau substrate ntawm LED nti.
