Rogers 5880 laminate yog tsim los ntawm tib cov ntaub ntawv zoo thiab txhim khu kev qha thiab cov txheej txheem raws li Rogers, uas ua rau Rogers yeej qhov khoom plig tseem ceeb los ntawm cov khoom siv ntau zaus. Hauv qee qhov kev tsim, cov khoom dielectric ntawm PCB tseem ceeb heev. Txawm hais tias nws yog high-speed, RF, microwave lossis mobile, kev tswj fais fab yog qhov tseem ceeb. Koj yuav pom tias cov yam ntxwv dielectric ntawm lub rooj tsav xwm hauv Circuit Court yog qhov xav tau ntau dua li qhov tsis tau muab los ntawm tus qauv FR-4. Peb paub. Qhov no yog vim li cas peb txuas pcbexpress nrog rogers5880 dielectric cov ntaub ntawv. Cov ntaub ntawv poob qis tshiab no txhais tau tias kev ua tau zoo dua rau kev thov PCB qauv.

Vim li cas thiaj siv Rogers dielectric khoom?
Cov khoom siv FR-4 yog tus qauv yooj yim ntawm PCB substrate, uas tuaj yeem ua tiav qhov sib npaug ntawm tus nqi, kev tsim muaj peev xwm, kev ua haujlwm hluav taws xob thiab kav ntev. Tab sis yog tias cov yam ntxwv hluav taws xob thiab kev ua tau zoo tshaj yog lub hauv paus ntawm koj tus qauv tsim, Rogersmaterials yog koj qhov kev xaiv zoo tshaj plaws vim tias:
Txo dielectric poob
Tsawg poob zog siv teeb liab
Loj ntau DK (dielectric tas li) (2.55-10.2)
Tsawg nqi hluav taws xob tsim hluav taws xob
Tsawg cua tso tawm qhov chaw thov

Cov khoom siv dielectric
Cov khoom siv dielectric yog cov khoom siv tsis zoo, uas yog siv los ua ib txheej insulating hauv PCB qauv. Qee qhov dielectric yog mica, thiab qee qhov dielectric yog mica, hlau oxide, thiab yas. Qhov qis dielectric poob (lub zog poob hauv daim ntawv ntawm tshav kub), qhov zoo dua cov khoom siv dielectric. Yog hais tias qhov hluav taws xob nyob rau hauv cov khoom siv dielectric siab dhau lawm, uas yog, thaum lub electrostatic teb ua zog dhau lawm, cov khoom dheev pib ua tam sim no. Qhov tshwm sim no hu ua dielectric breakdown.

Ua ntej impregnation (pre preg)
Lub shrinkage ntawm “pre impregnated composite fiber” thiab zus tau tej cov PCB, pregS, yuav cuam tshuam cov kev ua tau zoo yam ntxwv ntawm luam Circuit Court board. Ib lo lus siv hauv kev lag luam PCB los piav txog cov khoom siv ntawm cov nplaum nplaum siv los txuas cov khaubncaws sab nraud povtseg, multilayer PCB.
Rtduroid5880 siab zaus laminate los ntawm Rogers
Rogers5880 high zaus laminate series txais PTFE puas iav fiber ntau. Cov microfibers no tau txheeb xyuas qhov zoo tshaj plaws ntawm fiber ntau thiab muab cov kev taw qhia tseem ceeb tshaj plaws rau cov tuam txhab tsim hluav taws xob thiab kev siv kawg. Lub dielectric tas li ntawm cov high-frequency laminates yog qhov qis tshaj ntawm tag nrho cov khoom, thiab qhov tsis tshua muaj dielectric poob ua rau lawv haum rau high-frequency / broadband daim ntaub ntawv qhov twg dispersion thiab poob yuav tsum tau txo. Vim nws qhov nqus dej tsawg heev, rtduroid5880 yog qhov tsim nyog rau siv nyob rau hauv qhov chaw muaj av noo.

Cov khoom siv hluav taws xob siab tshaj no tuaj yeem txiav tau yooj yim, txiav thiab ua tiav los ua cov kuab tshuaj thiab cov tshuaj reagent feem ntau siv hauv Circuit Board lossis ntug thiab qhov electroplating. Lawv muaj hluav taws xob tsawg heev rau cov khoom siv PTFE, thiab lawv kuj muaj qhov nqus dej tsawg heev thiab yog isotropic. Lawv muaj cov yam ntxwv hluav taws xob tsis sib xws hauv zaus. High zaus rtduroid5880 yog siv nyob rau hauv kev lag luam airlines, microstrip thiab stripline circuits, millimeter yoj system daim ntawv thov siv nyob rau hauv tub rog radars, missile system kav hlau txais xov, digital xov tooj cua taw tes qhia thiab lwm yam. Lub rtduroid5880 tau ntim nrog PTFE compound yog tsim los rau kev siv nruj ntawm kev sib xyaw ua ke thiab microcircuits.

Rogerpcb cov khoom muaj qhov qis tshaj DK tus nqi ntawm tooj liab laminate muaj nyob rau hauv kev ua lag luam. Vim nws qhov qis dielectric tsis tu ncua ntawm 1.96 ntawm 10GHz, rtduroid5880 txhawb nqa kev siv dav dav ntawm microwave zaus hauv millimeter ntau yam, uas cuam tshuam thiab kev poob qis yuav tsum raug txo kom tsawg. Nws yog ib qho puv, hnav PTFE sib xyaw nrog qhov ntom ntom ntom (1.37G / cm3) thiab qis coefficient ntawm thermal expansion (CTE) ntawm z-axis. Nws tuaj yeem muab cov khoom siv hluav taws xob ntau (PTH) qhov thiab ua tiav kev them nyiaj ntau dua. Tsis tas li ntawd, lub dielectric tsis tu ncua los ntawm phaj mus rau lub vaj huam sib luag yog sib xws thiab tas li nyob rau hauv ntau zaus, thiab z-axis tcdk yog tsawg li + 22ppm / ° C.
