Vim li cas cov ntaub ntawv hluav taws xob yog ib qho tseem ceeb hauv substrate hauv PCB kev lag luam?
Hauv PCB (Printed Circuit Board) kev lag luam saw, cov ntaub ntawv hluav taws xob, zoo li cov khoom siv tsis zoo, yog qhov tseem ceeb ntawm cov txheej txheem uas txhawb nqa tag nrho lub rooj tsav xwm Circuit Court kev ua tau zoo thiab kev ntseeg tau. Yog tsis muaj nws, cov qauv kev ruaj ntseg, hluav taws xob kev nyab xeeb, thiab kev hloov kho ntawm PCB yuav nyuaj rau kev ua tiav; Nws tuaj yeem suav tias yog lub cev tsis pom ntawm PCB.
Cov ntaub ntawv hluav taws xob yog cov tseem ceeb txhawb nqa substrate ntawm tooj liab clad laminate (CCL), uas nyob rau hauv lem yog cov tseem ceeb raw khoom ntawm PCB, tsim ib tug kaw kev lag luam saw txuas. Nws yog qhov tseeb woven los ntawm ultra-fine alkali-dawb iav fiber ntau xov, muaj cov khoom zoo uas cov khoom siv tsis tuaj yeem hloov tau, ua rau nws yog cov khoom tseem ceeb uas tsis tuaj yeem hloov tau hauv kev lag luam PCB.
Ua ntej, nws muab cov qauv kev txhawb nqa tseem ceeb.
Lub fibers mesh qauv ntawm cov ntaub ntawv hluav taws xob ua tau zoo txhim kho lub zog thiab qhov ruaj khov ntawm PCB, tiv thaiv warping, deformation, thiab tawg thaum ua, sib dhos, thiab siv. Tshwj xeeb tshaj yog nyob rau hauv multilayer thiab siab - ntom PCBs, nws ua tau zoo xyuas kom meej kev sib raug zoo ntawm cov txheej txheem Circuit Court thiab tag nrho cov qauv kev ruaj ntseg.
Qhov thib ob, nws ua kom muaj kev nyab xeeb ntawm hluav taws xob rwb thaiv tsev.
PCBs yog them nrog conductive tooj liab ntawv ci. Cov ntaub ntawv hluav taws xob, nrog rau nws cov hluav taws xob zoo heev, thaiv tag nrho cov kev pheej hmoo ntawm kev xau thiab luv luv ntawm cov kab no. Nws kuj muaj cov yam ntxwv tsis tshua muaj dielectric tsis tu ncua thiab tsis tshua muaj dielectric poob, ua rau nws haum rau siab - zaus, siab -ceev xwm txheej xws li 5G thiab AI servers, txo cov teeb liab attenuation thiab cuam tshuam, thiab xyuas kom meej thiab muaj txiaj ntsig teeb liab kis tau tus mob.
Thib peb, nws tiv taus kev ua haujlwm hnyav.
Cov ntaub ntawv hluav taws xob muaj cov cua kub zoo heev, muaj peev xwm tiv taus qhov kub thiab txias ntawm PCB tsim cov txheej txheem xws li nias thiab soldering. Nws kuj tseem tiv taus cov tshuaj corrosion thiab damp kub laus, tswj kev ua haujlwm ruaj khov txawm tias nyob hauv ib puag ncig nyuaj xws li qhov kub thiab qis qis thiab cov av noo, ncua lub neej ntawm PCBs.
Hauv kev xaus, xav txog peb lub zog no,
cov ntaub ntawv hluav taws xob, nrog rau nws cov txiaj ntsig zoo ntawm cov qauv kev txhawb nqa, hluav taws xob rwb thaiv tsev, thiab kev tiv thaiv tshav kub, tau dhau los ua ib qho tseem ceeb hauv kev lag luam PCB thiab lub hauv paus tseem ceeb rau cov khoom siv hluav taws xob siab tshaj - kev loj hlob ntawm kev lag luam hluav taws xob.
Los ntawm kev tsim kho kev lag luam, kev siv thev naus laus zis ntawm cov ntaub ntawv hluav taws xob ncaj qha ua rau kev txhim kho ntawm PCB kev lag luam. Raws li PCBs txhim kho mus rau qhov muaj zaus, kev kub ceev, ultra-thinness, thiab kev ntseeg siab, siab -kawg cov khoom xws li qis-dielectric electronic ntaub, ultra-thin electronic fabric, thiab high-heat-cov ntaub ntawv hluav taws xob tiv taus tau tshwm sim, dhau los ua cov ntaub ntawv tseem ceeb rau cov ntaub ntawv siv hluav taws xob, cov ntaub ntawv hluav taws xob tsawg, ultra-cov ntaub ntawv nyias nyias, thiab siab - tshav kub- cov ntaub ntawv hluav taws xob tiv taus tau tshwm sim, dhau los ua cov ntaub ntawv tseem ceeb rau cov khoom siv hluav taws xob, cov ntaub ntawv hluav taws xob thiab cov chaw tshiab. Nws tuaj yeem hais tias cov txheej txheem thev naus laus zis ntawm cov ntaub siv hluav taws xob ncaj qha txiav txim siab qhov siab -kawg txoj kev loj hlob ntawm PCB kev lag luam thiab yog lub hauv paus lav rau tag nrho cov khoom siv hluav taws xob thiab cov ntaub ntawv kev lag luam.
Txawm hais tias nyob rau hauv txhua txhua hnub cov neeg siv khoom siv hluav taws xob lossis siab -kawg teb xws li kev lag luam, kev sib txuas lus, thiab tsheb, cov ntaub ntawv hluav taws xob ntsiag to txhawb kev txhim kho ruaj khov ntawm PCB kev lag luam. Nws txoj haujlwm tseem ceeb tseem ceeb tau ntev tau pom zoo hauv kev lag luam thiab yog qhov tseem ceeb ntawm kev ntseeg siab rau siab - kev loj hlob zoo ntawm kev lag luam hluav taws xob tsim khoom.
