Dab tsi yog qhov zoo ntawm FR4 cov ntaub ntawv hauv PCB kev tsim khoom

FR-4 khoom, qhov no yog cov lus luv luv ntawm iav fiber ntaub, nws yog ib hom ntawm cov khoom siv raw thiab substrate Circuit Board, qhov dav dav dav, ob chav thiab ntau txheej Circuit Court board tau ua los ntawm qhov no! Nws yog ib qhov lus pom zoo heev

 phaj! Xws li Shengyi, Jiantao (KB), Jin An Guoji yog peb qhov kev lag luam loj hauv tebchaws, xws li tsuas yog ua FR-4 cov ntaub ntawv ntawm cov tuam txhab Circuit Court manufacturers: Wuzhou Electronics, Penghao Electronics, Wanno Electronics, lawv tau ua cov khoom no zoo heev cov tuam ntxhab.

Lub sijhawm ntev; Cov ntawv luam tawm Circuit Board (PCBs) tau yog ib feem ntawm ntau lub xov tooj cua hluav taws xob. Raws li qhov tshwm sim, feem ntau ntawm cov hluav taws xob cov tshuab hluav taws xob koom nrog kev tsim cov ntawv cog lus Circuit Court yog paub nrog cov khoom sib txawv uas siv los ua lawv. FR4 yog ib qho khoom siv nrov tshaj plaws los siv los ua cov PCBs. Dab tsi ua rau cov ntaub ntawv nrov? Ntawm no pls pub kuv los qhia txog ntau yam ntawm FR4 cov ntaub ntawv siv nyob rau hauv cov ntawv luam tawm Circuit Court.

 

Taw qhia ntawm FR4 cov ntaub ntawv

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

 

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

FR4 yog cov khoom siv qes.

1, Nws muaj lub zog dielectric muaj zog, uas ua rau nws ua tau zoo hauv hluav taws xob rwb thaiv tsev.

2, Cov khoom siv muaj qhov sib zog-rau-qhov hnyav thiab qhov yog qhov hnyav hauv qhov hnyav.

3, Nws yog cov dej noo-pov thawj thiab muaj qhov ntsuas kub zoo.

4, Cov khoom siv muaj cov hluav taws xob zoo dissipation cov cuab yeej.

5, FR4 tsis nqus dej, yog li nws haum rau txhua yam ntawm Marine PCB thov.

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

 

FR4 tseem muaj kev teeb tsa li cas rau cov pa FR4 luam tawm puag ncig? FR4 ua lub hauv paus rau ib qho PCB twg. Cov khoom siv laminated nrog ntawv ci tooj liab. Siv kub thiab pleev nplaum rau laminate. Tooj liab ntawv ci tuaj yeem siv rau laminate cov khoom siv los ntawm ib qho lossis ob tog.
