FR -4 Rigid PCB

FR -4, yog ib qho ntawm cov khoom siv PCB feem ntau, yog cov cai rau qib ntawm cov khoom siv raw thiab cov khoom siv hluav taws kub tsis zoo ntawm PCB substrates, uas sawv cev rau cov khoom siv tshwj xeeb uas cov khoom siv cob yuav tsum tuaj yeem tua tus kheej tom qab combustion. . Nws yog feem ntau siv hauv PCB. Cov qauv no feem ntau siv rau ib lub vaj huam sib luag, ob sab thiab ntau txheej Circuit Court boards. Vim nws lub zog siab thiab nplaim taws, feem ntau cov tuam txhab tsim hluav taws xob yuav xaiv FR -4 ua cov khoom siv hauv paus. Ntxiv rau cov qauv no, muaj FR-1, CEM-3 thiab lwm yam qauv qauv.

Yam ntxwv

1.Nws muaj lub cev zoo thiab cov khoom siv hluav taws xob zoo, kev ua haujlwm zoo rwb thaiv tsev, thiab tuaj yeem ua haujlwm hauv qhuav -35 ~ +100 degree huab cua nruab nrab ib puag ncig nrog kev xav tau ntawm hluav taws xob coefficient.

2. Qhov saum npoo ntawm FR-4 board yog du thiab tiaj tus, thiab nws yog kub resistant, noo noo resistant, pwm resistant, acid thiab alkali resistant, thiab cuam tshuam resistant. Nws cov khoom siv hluav taws xob, cov khoom dielectric, thiab cov khoom ua haujlwm zoo. Kev ua haujlwm hluav taws xob nyob rau hauv qhuav thiab ntub dej kuj zoo heev. Qhov tseem ceeb tshaj plaws yog tias nws muaj cov nplaim hluav taws zoo, tsis tshua muaj kev cuam tshuam los ntawm ib puag ncig, thiab muaj qhov ruaj khov loj.

Lub sij hawm xa tuaj

# Hauv qab lub sij hawm txhuas yog raws li cov khoom me me thiab tom qab cov khoom siv raw tau npaj, Batch (ceev ceev) thiab Fast Run xav tau nqi ntxiv.
