Peb cov kev pab cuam yog txo nqi, dynamic nyiaj khwv tau los pab pawg neeg, tshwj xeeb QC, khoom factories, zoo sab saum toj cov khoom thiab cov kev pab cuam rau Circuit Court Board ,PCB los ua ke ,Me Luam Circuit Court Board , Ua lag ua luam philosophy: Siv tus neeg muas zaub raws li lub Center, coj qhov zoo raws li lub neej, kev ncaj ncees, lub luag hauj lwm, ua kom pom tseeb, innovation.We'll mov txawj, zoo nyob rau hauv rov qab rau lub koomhaum uas cov neeg muas zaub, nrog rau feem ntau loj ntiaj teb no lwm? E? Tag nrho cov ntawm peb cov neeg ua haujlwm yuav ua hauj lwm ua ke thiab txav mus rau pem hauv ntej ua ke.
Lub substrate ntawm High TG Circuit Court board yuav hloov los ntawm "lub khob xeev" mus rau "roj hmab xeev" thaum kub nce mus rau ib tug tej yam cheeb tsam, thiab qhov no kub yog hu ua tus iav hloov kub (TG) ntawm lub Rooj Tswjhwm Saib. Nyob rau hauv lwm yam lus, TG yog lub siab tshaj plaws kub (℃) nyob rau hauv uas lub substrate tseem txhav. Uas yog hais tias, zoo tib yam PCB substrate ntaub ntawv nyob rau high school kub tsis tau tsuas yog tsim softening, deformation, melting thiab lwm yam tshwm sim, tab sis kuj ua tau zoo nyob rau hauv tus neeg kho tshuab, hluav taws xob cov yam ntxwv ntawm ib tug ntse poob (Kuv tsis xav hais tias peb xav pom lawv cov khoom tshwm sim qhov teeb meem no).
Feem ntau hais lus, lub Rooj Tswjhwm Saib ntawm TG yog ntau tshaj li 130 degrees, siab TG yog ntau tshaj li 170 degrees, thiab nruab nrab TG yog ntau tshaj li 150 degrees.
Feem ntau Tg≥170 ℃ PCB, hu ua siab TG PCB.
Thaum lub TG ntawm lub substrate nce, lub Circuit Court board lub tshav kub tsis kam, ya raws kuj, tshuaj lom neeg kuj, stability kuj thiab lwm yam ntxwv yuav tau zoo tuaj. Lub siab dua tus TG nqi, qhov zoo qhov kub thiab txias tsis kam ntawm lub phaj. Thiab lub siab TG yog feem ntau thov nyob rau hauv cov hmoov txhuas-free txheej txheem,
High TG hais txog kub siab kuj. Nrog rau cov kev ceev txoj kev loj hlob ntawm lub tshuab hluav taws xob kev lag luam thiab lub tshuab hluav taws xob khoom sawv cev los ntawm lub computer, qhov ntau dua thaum tshav kub kub kuj PCB substrate ntaub ntawv tau ua ib qho tseem ceeb guarantee thaum txoj kev loj hlob ntawm rau hauv ib lub high school cov nuj nqi thiab siab multilayer. Yog dab tsi ntxiv, cov tsos thiab kev loj hlob ntawm high-density installation technology sawv cev los ntawm SMT thiab CMT ua PCB ntau thiab ntau inseparable los ntawm cov nyiaj them yug ntawm kub siab kuj muaj substrate nyob rau hauv me me aperture, zoo Circuit Court thiab nyias daim ntawv.
Yog li ntawd, qhov txawv ntawm qhov kev fr-4 thiab lub siab TG fr-4 yog tias nyob rau hauv lub thermal lub xeev, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm tshav kub tom qab dej haum. Thiab muaj ntau ntau yam sib txawv nyob rau hauv tus neeg kho tshuab zog, seem stability, adhesion, dej haum, thermal decomposition, thermal expansion thiab lwm yam tej yam kev mob ntawm cov ntaub ntawv. Cov khoom uas muaj TG yog obviously zoo dua tib yam PCB substrate cov ntaub ntawv. Nyob rau hauv xyoo tsis ntev los, cov xov tooj ntawm cov neeg muas zaub tau zus tau tej cov siab TG Circuit Court board nce xyoo los ntawm xyoo.
