Taw qhia ntawm FR4 cov ntaub ntawv

FR hauv FR4 sawv cev rau cov nplaim hluav taws, thiab tus naj npawb 4 txawv cov khoom siv los ntawm lwm cov ntaub ntawv hauv chav kawm no.FR4 yog iav fiber ntau reinforced epoxy laminate uas zoo li daim ntaub nyias nyias.Lub sij hawm FR4 kuj sawv cev rau qib siv los ua cov laminates.Cov qauv fiberglass muab cov qauv kev ruaj ntseg rau cov khoom siv.Cov iav fiber ntau yog them nrog nplaim hluav taws kub epoxy.Qhov no muab cov khoom durability thiab muaj zog mechanical zog.Tag nrho cov yam ntxwv no ua rau FR4 luam tawm Circuit Board nrov heev ntawm cov tuam txhab hluav taws xob cog lus.

Lub FR4 luam tawm Circuit Board tseem nrov rau cov laj thawj hauv qab no:

FR4 yog cov khoom siv qis.

1, Nws muaj lub zog dielectric siab, uas ua rau nws cov hluav taws xob rwb thaiv tsev ua haujlwm.

2, Cov khoom muaj lub zog-rau-hnyav piv thiab yog lub teeb hauv qhov hnyav.

3, Nws yog dej-pov thawj thiab muaj tus txheeb ze kub.

4, Cov khoom siv hluav taws xob zoo dissipation.

5, FR4 tsis nqus dej, yog li nws tsim nyog rau txhua yam kev siv Marine PCB.

6, cov ntaub ntawv yog daj rau lub teeb ntsuab, zoo tagnrho rau txhua daim ntawv thov.Tag nrho cov nta no ua rau nws haum rau ntau qhov chaw ib puag ncig.

Yuav ua li cas FR4 teeb tsa ntawm cov pa FR4 luam tawm Circuit Board?FR4 yog lub hauv paus rau txhua tus PCB.Cov khoom yog laminated nrog tooj liab ntawv ci.Siv cov cua sov thiab nplaum rau laminate.Copper foil tuaj yeem siv los laminate cov khoom ntawm ib lossis ob sab.
