Luluphi udidi lwebhodi yeRogers PCB?

Izinto zeRogers RO4350B zivumela iinjineli zeRF PCB ukuba ziyile iisekethe ngokulula, ezinje ngothungelwano oluhambelanayo kunye nolawulo lokuthintela iintambo zothumelo.Ngenxa yeempawu eziphantsi zokulahleka kwe-dielectric, izinto ze-RO4350B zinenzuzo engenakulinganiswa kwizinto eziqhelekileyo zesekethe kwizicelo eziphezulu ze-frequency.Ukwahluka kwemvume kunye nobushushu buphantse buphantsi phakathi kwezixhobo ezifanayo, kwaye imvume yayo nayo izinzile kuluhlu olubanzi lwamaza, kunye nesindululo soyilo lwe-3.66.I-LoPra™ i-Copper foil inciphisa ilahleko yokufaka.Oku kwenza ukuba izinto zilungele izicelo zebroadband.

ibhodi Rogers PCB: imathiriyeli ye-ceramic yodidi oluphezulu lwe-PCB:

Uchungechunge lwe-RO3000: Izinto ze-PTFE zesekethe ezisekelwe ekuzalisweni kwe-ceramic, iimodeli zezi: RO3003, RO3006, RO3010, RO3035 i-laminate ephezulu-frequency.

Uthotho lwe-RT6000: olusekwe kwi-ceramic ezaliswe yi-PTFE yesekethe imathiriyeli, eyilelwe iisekethe zombane kunye neesekethe ze-microwave ezifuna imvume ephezulu.Iimodeli zezi: imvume ye-RT6006 6.15, i-RT6010 imvume ye-10.2.

Uchungechunge lwe-TMM: izinto ezidibeneyo ezisekelwe kwi-ceramic, i-hydrocarbon, i-polymer thermosetting, imodeli: TMM3, TMM4, TMM6, TMM10, TMM10i, TMM13i., njl.
Izinto ze-RO4003 zinokususwa ngebrashi yenylon eqhelekileyo.Akukho ukuphathwa okukhethekileyo okufunekayo phambi kobhedu lwe-electroplating ngaphandle kombane.Ipleyiti kufuneka iphathwe nge-epoxy yesiqhelo / inkqubo yeglasi.Ngokubanzi, akuyomfuneko ukususa umngxuma wokutsala amanzi ngenxa yokuba inkqubo ye-resin ye-TG ephezulu (280°C + [536°F]) ayiguquguquki lula ngexesha lenkqubo yokomba.Ukuba ibala libangelwa kukusebenza okundlongondlongo, i-resin inokususwa ngokusebenzisa umjikelo we-plasma we-CF4 / O2 oqhelekileyo okanye inkqubo ye-alkaline permanganate ezimbini.

Iimfuno zokupheka zezinto ze-RO4000 zifaniswa nezo ze-epoxy / glass.Ngokubanzi, izixhobo ezingapheki i-epoxy/glass plates azidingeki ukuba zipheke i-RO4003 PCBs.Ukufakwa kweglasi epoxy / ebhaka njengenxalenye yenkqubo eqhelekileyo, sincoma ukupheka kwi-300 ° F, 250 ° F (121 ° C-149 ° C) kwi-1 ukuya kwiiyure ze-2.I-RO4003 ayinazithinteli zomlilo.Kuyaqondakala ukuba, iipleyiti ezifakwe kwiiyunithi ze-infrared (IR) okanye ezisebenza ngesantya esisezantsi kakhulu sothumelo zinokufikelela kumaqondo obushushu angaphezu kwama-700°F (371 °C);I-RO4003 inokuqalisa ukutshisa kula maqondo obushushu aphezulu.Iinkqubo ezisasebenzisa izixhobo ze-infrared reflux okanye ezinye izixhobo ezinokufikelela kula maqondo obushushu aphezulu kufuneka zithathe amanyathelo okhuseleko ayimfuneko ukuqinisekisa ukuba akukho mngcipheko.

I-Ro3003 yibhodi ye-Rogers PCB yebhodi ye-ceramic ezaliswe yi-PTFE edibeneyo yorhwebo lwe-microwave kunye nezicelo ze-RF.Olu luhlu lweemveliso zenzelwe ukubonelela ngokuzinza kombane kunye nomatshini kwixabiso elikhuphisanayo.I-Rogers Ro3003 inozinzo oluhle kakhulu lwemvume phezu koluhlu lonke lobushushu, kubandakanywa nokupheliswa kweenguqu zemvume ezenzekayo xa izinto zeglasi ze-PTFE zisetyenziselwa ubushushu begumbi.Ukongeza, i-Ro3003 laminates ine-coefficients yokulahlekelwa ephantsi njenge-0.0013 ukuya kwi-10 GHz.
