Rogers PCB vs FR4 PCB: Kev sib piv ntawm Cov Khoom thiab Cov Khoom Siv

Paub txog qhov sib txawv ntawm ntau hom yog qhov tseem ceeb thaum xaiv lub rooj tsav xwm zoo tshaj plaws (PCB) rau koj cov khoom siv hluav taws xob. Ob qhov kev xaiv nrov ntawm kev ua lag luam niaj hnub no yog Rogers PCB thiab FR4 PCB. Txawm hais tias ob qho tib si muaj cov haujlwm zoo sib xws, lawv muaj cov khoom sib txawv thiab cov khoom siv sib xyaw, uas tuaj yeem cuam tshuam rau lawv qhov kev ua tau zoo. Ntawm no peb yuav ua qhov sib piv tob ntawm Rogers PCBs thiab FR4 PCBs los pab koj txiav txim siab paub txog koj qhov project tom ntej.

1. Khoom muaj pes tsawg leeg:

Rogers PCBs board muaj ntau zaus ceramics puv laminates nrog cov khoom siv hluav taws xob zoo xws li tsis tshua muaj hluav taws xob poob thiab thermal conductivity. Ntawm qhov tod tes, FR4 PCB pawg thawj coj saib, tseem hu ua Flame Retardant 4, yog ua los ntawm iav fiber reinforced epoxy resin khoom. FR4 paub txog nws cov hluav taws xob rwb thaiv tsev zoo thiab kev ruaj ntseg txhua yam.

2. Dielectric tas li thiab dissipation yam:

Ib qho ntawm qhov sib txawv tseem ceeb ntawm Rogers Circuit Board thiab FR4 Circuit Board yog lawv cov dielectric tas li (DK) thiab dissipation factor (DF). Rogers PCBs muaj DK qis thiab DF ua rau lawv haum rau cov ntawv thov ntau zaus uas qhov teeb meem kev ncaj ncees yog qhov tseem ceeb. Ntawm qhov tod tes, FR4 luam ntawv Circuit Court board muaj siab DK thiab DF, uas tej zaum yuav tsis zoo tagnrho rau high-frequency circuits uas yuav tsum tau lub sij hawm thiab kis tau tus mob.

3. Kev ua haujlwm siab:

Rogers luam ntawv Circuit Court boards yog tsim tshwj xeeb los tswj cov teeb liab zaus thiab tswj lawv txoj kev ncaj ncees. Nws qhov tsis tshua muaj hluav taws xob tsawg txo qis cov teeb liab poob thiab cuam tshuam, ua rau nws xaiv zoo heev rau kev siv microwave thiab RF. FR4 PCB circuits, thaum tsis ua kom zoo rau cov zaus siab li Rogers PCBs Circuit Board, tseem tsim nyog rau kev siv dav dav thiab nruab nrab zaus.

4. Thermal tswj:

Nyob rau hauv cov nqe lus ntawm thermal tswj, Rogers PCB yog zoo dua FR4 luam Circuit Court. Nws cov thermal conductivity siab ua kom muaj cua sov kom zoo, ua rau nws tsim nyog rau kev siv fais fab lossis cov khoom siv uas tsim kom muaj cua sov ntau. FR4 PCBs muaj cov thermal conductivity qis dua, uas tuaj yeem ua rau muaj kev ua haujlwm siab dua thiab xav tau cov tshuab cua txias ntxiv.

5. Tus nqi txiav txim siab:

Tus nqi yog ib qho tseem ceeb rau kev txiav txim siab thaum xaiv ntawm Rogers luam tawm circuits thiab FR4 PCBs. Rogers PCBs feem ntau kim dua vim lawv cov khoom tshwj xeeb muaj pes tsawg leeg thiab kev ua tau zoo dua qub.FR4 PCBs tau tsim thiab yooj yim, ua rau lawv muaj txiaj ntsig zoo rau kev siv dav dav.

6. Mechanical zog thiab durability:

Thaum ob leeg Rogers PCB thiab FR4 PCB muaj lub zog zoo thiab ua haujlwm ntev, Rogers PCB muaj kev ruaj ntseg zoo dua vim nws cov ceramic ntim laminate. Qhov no ua rau nws tsis tshua muaj deform los yog khoov hauv siab. FR4 PCBs tseem yog ib qho kev xaiv zoo rau feem ntau cov ntawv thov, txawm hais tias kev txhawb nqa ntxiv yuav xav tau rau qhov chaw hnyav dua.
Raws li kev txheeb xyuas saum toj no, nws tuaj yeem txiav txim siab tias qhov kev xaiv ntawm Rogers PCBs thiab FR4 PCBs nyob ntawm qhov tshwj xeeb ntawm koj qhov project. Yog tias koj ua haujlwm hauv cov ntawv thov zaus uas yuav tsum tau muaj kev ntseeg siab zoo thiab kev tswj xyuas thermal, Rogers PCBs yuav yog qhov kev xaiv zoo dua, txawm tias tus nqi siab dua. Ntawm qhov tod tes, yog tias koj tab tom nrhiav kev daws teeb meem zoo rau kev siv dav dav lossis nruab nrab zaus, FR4 PCBs tuaj yeem ua tau raws li koj qhov yuav tsum tau ua thaum muab lub zog zoo txhua yam. Thaum kawg, kev nkag siab txog cov khoom thiab cov khoom muaj pes tsawg leeg ntawm cov PCB hom no yuav pab koj txiav txim siab paub uas ua tau raws li koj qhov project xav tau.
