Khoom Paub meej

High-TG PCB yog hais txog cov ntawv luam tawm hauv Circuit Court uas tsim los siv cov iav siab - hloov pauv - kub FR4 cov khoom siv dielectric. TG (iav-kev hloov pauv kub) sawv cev rau qhov ntsuas kub uas cov khoom siv hloov pauv los ntawm cov iav khov-zoo li lub xeev mus rau cov roj hmab mos-zoo li lub xeev. Piv nrog rau tus qauv FR4, siab -TG PCBs muaj qhov ua tau zoo dua cov cua sov, qhov thermal stability thiab tsis kam rau thermal stress thaum lub sij hawm ntau qhov kub siab ua haujlwm xws li reflow soldering. Lawv txo cov kev pheej hmoo ntawm delamination, blistering thiab txheej sib cais, dav siv rau siab - lub hwj chim boards, multilayer PCBs, HDI boards thiab cov khoom ua hauj lwm nyob rau hauv sustained elevated - kub. Txawm li cas los xij, siab -TG cov ntaub ntawv tuaj nrog cov khoom siv siab dua thiab cov nqi tsim khoom. Cov kws tsim khoom thiab pab pawg yuav khoom yuav tsum tau txais siab siab -TG PCBs tsuas yog thaum cov cua sov ua kom pom tseeb qhov kev txhim kho, tsis txhob siv siab -TG specifications rau txhua qhov haujlwm.

Nkag siab txog tus nqi TG

TG stands rau iav Transition Temperature. Nws sawv cev rau qhov kub ntawm qhov uas PCB substrate hloov los ntawm lub xeev nruj mus rau lub xeev softer, hloov tau yooj yim dua.

Thaum PCB rov ua haujlwm nyob ze lossis siab dua nws tus nqi TG, cov khoom siv yuav ntsib:

Dimensional instability

Nce expansion tus nqi

Txo qhov kev ntseeg tau

Txheej kev sib cais txaus ntshai

Kev sib dhos tsis raug

Standard FR4 cov ntaub ntawv feem ntau muaj TG tus nqi nyob ib ncig ntawm 130℃txog 140 degree, thaum High TG laminates feem ntau yog li ntawm 170℃mus rau ntau tshaj 180 degree.

Qhov siab dua TG tsis tas txhais tau tias kev ua tau zoo ntawm hluav taws xob, tab sis nws feem ntau txhais tau tias kev ua kom zoo dua thermal endurance thiab txhim kho kev ntseeg siab hauv qhov xav tau ib puag ncig.

High TG PCB vs Standard FR4

Ib qho ntawm cov lus nug ntau tshaj plaws yog qhov kev hloov kho rau cov khoom siv siab TG yog qhov tsim nyog.

Cov lus teb feem ntau nyob ntawm cov khoom siv kev ua haujlwm.
