Rogers 5880 laminate yakagadzirwa neyemhando yepamusoro uye yakavimbika zvinhu uye maitiro saRogers, izvo zvinoita kuti Rogers akunde yakakosha mibairo kubva kune yakakwira-frequency zvinhu vanogadzira. Mune mamwe magadzirirwo, iyo dielectric zvimiro zvePCB zvakakosha. Kunyangwe iri high-speed, RF, microwave kana nhare, simba rekutonga ndiro kiyi. Iwe uchaona kuti dielectric maitiro edunhu bhodhi mune prototype anodiwa zvakanyanya kupfuura ayo asina kupihwa neyakajairwa FR-4. Tinoziva. Ichi ndicho chikonzero isu tichiwedzera pcbexpress ne rogers5880 dielectric zvinhu. Izvi zvitsva zvakaderera kurasikirwa dielectric zvinhu zvinoreva kushanda kwepamusoro kwekuda PCB prototypes.

Sei uchishandisa Rogers dielectric zvinhu?
FR-4 zvinhu ndiyo yakakosha chiyero che PCB substrate, iyo inogona kuwana kuenzana kwakanaka pakati pemari, simba rekugadzira, kushanda kwemagetsi uye kusimba. Asi kana hunhu hwemagetsi uye kuita kwepamberi kuri hwaro hwedhizaini yako, Rogersmaterials ndiyo sarudzo yako yakanaka nekuti:
Deredza kurasikirwa kwedielectric
Low kurasikirwa kwesimba rekushandisa chiratidzo
Yakakura mhando DK (dielectric inoenderera) (2.55-10.2)
Yakaderera mutengo wedunhu kugadzira
Low air kuburitsa nzvimbo application

Dielectric zvinhu
Dielectric material chinhu chine hutsika husina kunaka, chinoshandiswa sechidzitiro chekudzivirira muPCB chimiro. Imwe ye dielectric ndeye mica, uye imwe ye dielectric ndeye mica, metal oxide, uye plastiki. Iyo yakaderera iyo dielectric kurasikirwa (simba rakarasika nenzira yekupisa), iyo inonyanya kushanda iyo dielectric zvinhu. Kana iyo voltage mune dielectric zvinhu ikakwira zvakanyanya, ndiko kuti, kana iyo electrostatic munda ikanyanya kusimba, iyo inongoerekana yatanga kuita ikozvino. Chiitiko ichi chinonzi dielectric breakdown.
Zvivakwa zve rtduroid5880
Yakanyanya kuderera kurasikirwa mikana kune chero yemagetsi yakasimbiswa PTFE zvinhu
Kunyura kwakaderera
Isotropy
Kuita kwemagetsi neuniform frequency
Yakanakisa makemikari kuramba, anosanganisira zvinonyungudutsa uye reagents kudhinda uye kupfeka
Mhoteredzo ine ushamwari
Pre impregnation (preg)
Iyo shrinkage ye “pre impregnated composite fiber” uye kugadzirwa kwePCB, pre PregS, kuchakanganisa maitiro ekuita kweakadhindwa redunhu bhodhi. Izwi rinoshandiswa muindasitiri yekugadzira PCB kutsanangura zvinhu zveadhesive layer inoshandiswa kubatanidza ma layer, multilayer PCB.
Rtduroid5880 yakakwira frequency laminate kubva kuRogers
Rogers5880 high frequency laminate series inotora PTFE composite yakasimbiswa girazi fiber. Aya ma microfibers akatariswa nenhamba kuti awedzere mabhenefiti efiber kuwana uye anopa iyo inonyanya kukosha gwara kune vanogadzira dunhu uye yekupedzisira-kushandisa maapplication. Iyo dielectric garage yeaya epamusoro-frequency laminates ndiyo yakaderera pane zvese zvigadzirwa, uye yakaderera dielectric kurasikirwa inoita kuti ive yakakodzera kune yakakwira-frequency / Broadband application uko kupararira uye kurasikirwa kunofanirwa kudzikiswa. Nekuda kwekudzika kwayo kwemvura kunyura, rtduroid5880 yakakodzera kwazvo kushandiswa munzvimbo ine hunyoro hwepamusoro.

Izvi zvemberi zvedunhu zvinhu zvinogona kucheka zviri nyore, kucheka uye kugadziriswa kuita chero solvent uye reagent inowanzoshandiswa mumabhodhi edunhu kana kumucheto uye gomba electroplating. Vane kurasikirwa kwemagetsi kwakaderera kune chero yakasimbiswa PTFE zvinhu, uye ivo zvakare vane yakaderera kunyorova kwemvura uye isotropic. Vane maitiro emagetsi akafanana muhuwandu. Yakakwira frequency rtduroid5880 inoshandiswa mundege dzekutengesa, microstrip uye stripline maseketi, millimeter wave system application inoshandiswa mumaradhi emauto, missile system antennas, digital radio point show nezvimwe. Iyo rtduroid5880 yakazadzwa nePTFE komboni yakagadzirirwa kushandiswa kwakasimba kwemaseketi akabatanidzwa uye microcircuits.

Rogerpcb zvinhu zvine yakaderera DK kukosha kwemhangura laminate inowanikwa pamusika. Nekuda kweiyo yakaderera dielectric kugara kwe1.96 pa10GHz, rtduroid5880 inotsigira Broadband application ye microwave frequencies mumillimeter renji, umo kupararira uye kurasikirwa kwedunhu kunofanirwa kudzikiswa. Iyo imwechete yakazadzwa, yakareruka PTFE inoumbwa ine yakanyanya kuderera density (1.37G / cm3) uye yakaderera coefficient yekuwedzera kwekushisa (CTE) paz-axis. Iyo inogona kupa yakakwira-frequency kugadzira (PTH) maburi uye kuwana yakakwira mubhadharo. Pamusoro pezvo, iyo dielectric inogara kubva pandiro kuenda pane pane yakafanana uye inogara iri muhupamhi frequency renji, uye z-axis tcdk yakadzikira se + 22ppm / ° C.
