Qhov tshwm sim ntawm 5G xov tooj ntawm tes kev sib txuas lus tau ua rau muaj kev sib tham txog kev tsim cov kab hluav taws xob ceev ceev thoob plaws ntiaj teb.Cov kws tshaj lij tab tom nrhiav txoj hauv kev zoo tshaj plaws los xa cov teeb liab thiab zaus los ntawm cov khoom siv tam sim no rau cov ntawv luam tawm Circuit Board (PCBs).

Lub hom phiaj ntawm tag nrho cov ntaub ntawv PCB yog xa hluav taws xob thiab muab rwb thaiv tsev ntawm tooj liab txheej txheej.Cov khoom siv tshaj plaws hauv pawg no yog FR-4.Txawm li cas los xij, cov cai ntawm koj lub rooj tsavxwm yuav raug cuam tshuam los ntawm ntau yam khoom siv PCB.Cov lus qhia xaiv cov khoom siv PCB hauv qab no, tsim los ntawm ABIS, tus kws tshaj lij PCB cov chaw tsim khoom nrog ntau tshaj 15 xyoo ntawm kev txawj ntse, yuav qhia koj seb yuav nrhiav dab tsi thaum nws los txog rau ntau yam khoom siv PCB.

Ib qho qauv siv hluav taws xob tsim hluav taws xob muaj xws li cov txheej txheem uas tsis yog-conductive dielectric substrate core txheej nrog rau dielectric laminated txheej.Cov txheej txheej laminate yuav ua lub hauv paus rau cov ntawv ci tooj liab thiab cov dav hlau fais fab.Cov khaubncaws sab nraud povtseg, uas ua haujlwm zoo li rwb thaiv tsev ntawm cov tooj liab cov txheej txheem thaum tso hluav taws xob, yog tsim los ntawm ntau yam khoom siv raws li lawv cov khoom.Ntau qhov kev ntsuas tshwj xeeb yog siv los txheeb xyuas cov thermal thiab hluav taws xob cov khoom ntawm cov ntaub ntawv txhawm rau txhawm rau txheeb xyuas cov ntaub ntawv tsim nyog rau cov txheej txheem substrate core thiab laminate txheej.Tsis tas li ntawd, cov khoom siv ntxiv xws li tshuaj lom neeg zoo thiab cov khoom siv kho tshuab yuav tsum raug tshuaj xyuas raws li tus kheej daim ntawv thov, vim tias PCB tuaj yeem siv rau hauv cov tshuab thiab cov khoom siv uas yuav raug rau cov dej noo ntau dua lossis muab tso rau hauv cov chaw nruj uas xav tau ntau dua PCBs.

Ib qho kev ntsuas ntawm qhov dielectric tas li (Dk) yog siv los txiav txim siab qhov hluav taws xob ua haujlwm ntawm lub high-ceev PCB khoom.Txhawm rau ua haujlwm raws li kev rwb thaiv tsev rau cov kab tooj liab thiab lub dav hlau fais fab, koj xav tau cov khoom siv nrog cov nqi qis Dk rau PCB txheej.Cov khoom xaiv yuav tsum tau ua kom nws cov Dk zoo ib yam li qhov ua tau thaum lub sijhawm nws lub neej rau ntau qhov ntau zaus.Cov ntsiab lus uas txiav txim siab qhov kev ua tau zoo ntawm hluav taws xob ntawm cov khoom siv dielectric siv hauv PCBs yog cov teeb liab kev ncaj ncees thiab impedance.

Raws li PCB, cua sov yuav raug tsim thaum nws ua hluav taws xob.Cov ntaub ntawv yuav degrade ntawm ntau tus nqi raws li qhov tshwm sim ntawm thermal stress qhov kub no yuav ua rau cov kab sib kis, cov khoom siv, thiab cov khoom siv dielectric.Tsis tas li ntawd, cua sov tuaj yeem ua rau qee cov ntaub ntawv nthuav dav, uas tsis zoo rau PCBs vim nws tuaj yeem ua rau tsis ua haujlwm thiab tawg.

Thaum ntsuas cov tshuaj tiv thaiv, hom ib puag ncig ntawm lub rooj tsav xwm Circuit Court yuav raug siv yog qhov tseem ceeb.Cov khoom uas koj xaiv yuav tsum muaj cov tshuaj tiv thaiv zoo thiab nqus dej me ntsis.Tsis tas li ntawd, engineers yuav tsum nrhiav cov khoom uas muaj cov nplaim hluav taws kub, uas txhais tau hais tias lawv yuav tsis hlawv ntev dua 10 mus rau 50 vib nas this thaum nplaim hluav taws kub.Cov txheej PCB tseem tuaj yeem pib sib cais ntawm qhov kub thiab txias, yog li nws yog ib qho tseem ceeb kom paub meej thaum qhov no tshwm sim.

Thaum koj xaiv cov ntaub ntawv raug, nqis peev nyiaj zoo, thiab tshuaj xyuas kev tsim khoom tsis zoo, koj yuav muaj ntau xyoo ntawm kev ua haujlwm tsis muaj teeb meem los ntawm koj lub rooj tsav xwm luam tawm.ABIS Circuits muab cov ntawv luam tawm zoo tshaj plaws.Txhua PCB uas peb muab yog tus nqi tsim nyog thiab tsim ua kom zoo.Yog xav paub ntxiv txog peb cov PCBs, thov Tiv tauj peb .
