Vim li cas siv FR4 los ua kom siab Tg PCBs?

Qee daim ntawv thov xav tau PCB kom tiv taus qhov kub thiab txias ntawm 200 ℃ lossis siab dua.Rau kev ua haujlwm txhim khu kev qha hauv cov ntawv thov kub, peb xav tau cov PCBs uas tsim los ntawm kev ua haujlwm tau zoo.Qhov blog no yog tsim los ua kom koj paub txog ib qho kev mob siab rau PCB, hu ua HIGH-TG.Cov nosiab tg PCBstuaj yeem tiv taus qhov kub hloov pauv iav ntawm PCBs thaum muab cov yam ntxwv hauv qab no:

1. Txhim kho impedance tswj

2. Kev tswj xyuas thermal zoo dua

3. Tsawg noo noo nqus

4. Kev ua tau zoo ib yam

FR4 - Cov khoom nyiam rau siab Tg PCBs

Rau huab cua kub ntau yam kev siv, siab Tg PCBs yog tsim siv FR-4 substrates.Fr-4 yog cov nplaim hluav taws kub nyhiab iav fiber ntau cov khoom siv epoxy uas nyob hauv ntau lub voj voog lamination, nyuaj PCB tuav thiab tso cai rau vuam tsis muaj hlau lead.Feem ntau FR-4 substrates muaj xws li ntshiab PTFE, ceramic-filled PTFE, thiab thermosetting hydrocarbon substrates.Cov nram qab no yog cov khoom tshwj xeeb ntawm FR-4 substrate uas ua rau nws zoo tagnrho rau PCBs rau kev thov.

1. Kev ua tau zoo ntawm hluav taws xob.

2. tuaj yeem tiv taus qhov tshwj xeeb drilling thiab plating los ntawm qhov (PTH) kev npaj.

3. Zoo heev plating los ntawm qhov kev ntseeg tau.

4. Tus nqi qis dua.

5. Stable dissipation factor (Df) piv rau lwm yam khoom siv PCB.

6. Cov tshuaj tiv thaiv zoo heev

7. Haum rau PCB tsim yuav tsum tau tswj nruj ntawm impedance

8. Shockproof, shockproof thiab nplaim retardant.

Xav txog nws qhov kev ua tau zoo tshwj xeeb hauv kev tswj xyuas thermal, FR-4 High Tg PCBs tau xaiv dav rau kev siv hauv kev suav, khaws cia thiab khoom siv, cov khoom siv hluav taws xob, kev sib txuas lus thiab kev sib txuas lus, aerospace & Defense, kev kho mob, Industrial & Instrumentation, thiab automotive & electronics industries.Kev lag luam tsheb thauj mus los.

Xaiv cov khoom tsim nyog kom ua tiav cov txiaj ntsig xav tau

Ntawm cov khoom siv FR-4 muaj, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov khoom tsim nyog rau daim ntawv thov, vim nws txiav txim siab qhov kev ruaj ntseg thiab kev ua tau zoo ntawm cov khoom kawg.Cov yam ntxwv xws li dielectric permittivity, poob coefficient, thermal conductivity, hloov kub, coefficient ntawm thermal expansion (CTE), hluav taws xob khoom, thiab lwm yam, yuav tsum tau txiav txim siab ua ntej xaiv FR-4 substrates rau koj daim ntawv thov.Yog tias koj tsis meej pem txog hom FR-4 cov khoom siv los xaiv, xav txog kev ua haujlwm nrog PCB cov chaw tsim khoom muaj kev paub txog kev muab siab Tg PCBs rau ntau yam kev lag luam.RigiFlex Technologies yog ib qho ntawm cov paub zooPCB manufacturersnyob rau hauv kev ua lag luam thiab lawv muaj kev sib koom tes ntawm kev xa khoom siab Tg PCBs hauv ntau qhov kev teeb tsa.Thov siab tg PCB nqe lus tam sim no!
