I-Rogers 5880 laminate yenziwe ngezinto ezikumgangatho ophezulu kunye nezithembekileyo kunye neenkqubo ezifana neRogers, eyenza uRogers aphumelele amabhaso abalulekileyo avela kubakhiqizi bezinto eziphathekayo eziphezulu. Kolunye uyilo, iipropathi zedielectric zePCB zibaluleke kakhulu. Nokuba sisantya esiphezulu, iRF, imicrowave okanye iselula, ulawulo lwamandla lungundoqo. Uya kufumanisa ukuba iimpawu ze-dielectric zebhodi yesiphaluka kwiprototype zifuneka ngakumbi kunezo zingabonelelwanga ngumgangatho we-FR-4. Siyazi. Yiyo loo nto sandisa pcbexpress nge rogers5880 imathiriyeli dielectric. Ezi zixhobo zintsha zelahleko eziphantsi zithetha ukusebenza okuphezulu kwiprototypes yePCB efunwayo.

Kutheni usebenzisa izinto ze-dielectric zikaRogers?
Izinto ze-FR-4 ngumgangatho osisiseko we PCB substrate, onokufikelela kwibhalansi efanelekileyo phakathi kweendleko, amandla okuvelisa, ukusebenza kombane kunye nokuqina. Kodwa ukuba iimpawu zombane kunye nokusebenza okuphezulu zisisiseko soyilo lwakho, iRogersmaterials lukhetho lwakho olufanelekileyo kuba:
Ukunciphisa ilahleko ye-dielectric
Ilahleko ephantsi yokusetyenziswa kwamandla uphawu
Uluhlu olukhulu lwe-DK (i-dielectric constant) (2.55-10.2)
Ukuveliswa kwesekethe ngexabiso eliphantsi
Ukusetyenziswa kwendawo yokukhupha umoya ophantsi

Izinto zedizeli
Isixhobo se-Dielectric sisixhobo esine-conductivity engafanelekanga, esetyenziswa njenge-insulating layer kwisakhiwo se-PCB. Enye idielectric yi mica, kwaye enye idielectric yi mica, metal oxide, kunye neplastiki. Ukunciphisa ilahleko ye-dielectric (amandla alahlekileyo ngendlela yokushisa), i-dielectric material isebenza ngakumbi. Ukuba i-voltage kwizinto ze-dielectric ziba phezulu kakhulu, oko kukuthi, xa intsimi ye-electrostatic iba namandla kakhulu, izinto eziphathekayo ziqala ukuqhuba ngoku. Le nto ibizwa ngokuba yi-dielectric breakdown.

Ukusebenza kombane kunye namaxesha afanayo
Ukuchasana kweekhemikhali okugqwesileyo, kubandakanywa i-solvents kunye ne-reagents yokuprinta kunye nokwaleka
Imekobume enobuhlobo
Ukukhulelwa kwangaphambili (preg)
Ukucutheka kwe “fiber composite fibre” kunye nokuveliswa kwe-PCB, i-PregS, kuya kuchaphazela iimpawu zokusebenza zebhodi yesekethe eprintiweyo. Igama elisetyenziswa kwishishini lemveliso ye-PCB ukuchaza izinto zomaleko wokuncamathelisa osetyenziselwa ukudibanisa iileya, i-PCB eninzi.
I-Rtduroid5880 i-laminate ephezulu yefrikhwensi evela kuRogers
Rogers5880 high frequency laminate series adopts PTFE composite ifayibha yeglasi eyomeleziweyo. Ezi microfibers zijoliswe ngokwamanani ukwandisa inzuzo yokuzuza ifayibha kwaye zibonelele ngeyona ndlela ixabisekileyo kubavelisi beesekethe kunye nezicelo zokugqibela zokusetyenziswa. I-dielectric constant of laminates ye-high-frequency laminates yiyona nto iphantsi kuzo zonke iimveliso, kwaye ilahleko ye-dielectric ephantsi yenza ukuba ifaneleke kwizicelo eziphezulu ze-frequency / broadband apho ukusabalalisa kunye nokulahleka kufuneka kuncitshiswe. Ngenxa yokufunxwa kwayo okuphantsi kakhulu kwamanzi, i-rtduroid5880 ikulungele kakhulu ukusetyenziswa kwindawo yokufuma okuphezulu.

Ezi zixhobo zesekethe eziphambili zinokunqunyulwa ngokulula, zinqunywe kwaye zicutshungulwe ukwenza nayiphi na i-solvent kunye ne-reagent esetyenziswa ngokuqhelekileyo kwiibhodi zeesekethe okanye i-edge kunye ne-electroplating yomngxuma. Banelahleko yombane ephantsi kakhulu kuyo nayiphi na imathiriyeli ye-PTFE eyomeleziweyo, kwaye banako ukufunxa okuphantsi kakhulu kokufuma kwaye basisotropic. Zineempawu ezifanayo zombane ngokuphindaphindiweyo. I-high frequency rtduroid5880 isetyenziswa kwiinqwelomoya zorhwebo, i-microstrip kunye neesekethe ze-stripline, izicelo ze-millimeter wave system ezisetyenziswa kwiirada zomkhosi, ii-eriyali zenkqubo ejulwayo, imiboniso yerediyo yedijithali kunye nabanye. I-rtduroid5880 ezaliswe nge-PTFE ikhompawundi yenzelwe ukusetyenziswa okungqongqo kweesekethe ezidibeneyo kunye ne-microcircuits.

Rogerpcb impahla inelona xabiso lisezantsi DK lelaminate yobhedu ekhoyo kwimarike. Ngenxa yokuguquguquka kwe-dielectric ephantsi ye-1.96 kwi-10GHz, i-rtduroid5880 ixhasa ukusetyenziswa kwe-broadband ye-microwave frequencies kuluhlu lwe-millimeter, apho ukusasazwa kunye nelahleko yesiphaluka kufuneka kuncitshiswe. Yintlupheko eyodwa ezaliswe ngokupheleleyo, ekhaphukhaphu ye-PTFE enoxinano oluphantsi kakhulu (1.37G / cm3) kunye ne-coefficient ephantsi yokwandiswa kwe-thermal (CTE) kwi-z-axis. Inokubonelela ngemingxuma yokuvelisa i-high-frequency (PTH) kunye nokufezekisa umvuzo ophezulu. Ukongeza, i-dielectric engaguqukiyo ukusuka kwipleyiti ukuya kwiphaneli iyafana kwaye ayiguquguquki kuluhlu olubanzi lwamaza, kwaye i-z-axis tcdk iphantsi njenge + 22ppm / ° C.
