Yiziphi izigaba zebhodi lebhodi leRogers PCB?
Izinto ze-Rogers RO4350B zivumela onjiniyela be-RF PCB ukuthi badizayine kalula amasekhethi, njengokumatanisa inethiwekhi nokulawulwa kokuphazamiseka kwemigqa yokudlulisela.Ngenxa yezici zayo eziphansi zokulahlekelwa kwe-dielectric, impahla ye-RO4350B inenzuzo engenakuqhathaniswa ngaphezu kwezinto ezivamile zesekethe kuzinhlelo zokusebenza ze-high-frequency.Ukuhluka kwemvume ngezinga lokushisa cishe kuphansi kakhulu phakathi kwezinto ezifanayo, futhi imvume yayo futhi izinzile kububanzi obubanzi befrikhwensi, ngesincomo sokuklama esingu-3.66.I-LoPra™ Copper foil inciphisa ukulahlekelwa kokufaka.Lokhu kwenza okokusebenza kulungele ukusetshenziswa kwe-broadband.
Rogers PCB board: impahla yochungechunge lwe-ceramic high frequency PCB:
Uchungechunge lwe-RO3000: Izinto zesekethe ye-PTFE esekelwe ekugcwalisweni kwe-ceramic, amamodeli yilawa: RO3003, RO3006, RO3010, RO3035 high-frequency laminate.
Uchungechunge lwe-RT6000: olusekelwe ezintweni zesekethe ezigcwele ze-PTFE, ezidizayinelwe amasekhethi e-electronic namasekhethi ama-microwave adinga imvume ephezulu.Amamodeli yilawa: RT6006 imvume 6.15, RT6010 imvume 10.2.
Uchungechunge lwe-TMM: izinto eziyinhlanganisela ezisekelwe ku-ceramic, i-hydrocarbon, i-thermosetting polymer, imodeli: TMM3, TMM4, TMM6, TMM10, TMM10i, TMM13i., njll.
I-RO4003 impahla ingasuswa ngebhulashi lenayiloni elivamile.Akukho ukuphatha okukhethekile okudingekayo ngaphambi kwe-electroplating yethusi ngaphandle kukagesi.Ipuleti kufanele liphathwe kusetshenziswa inqubo evamile ye-epoxy/glass.Ngokuvamile, akudingekile ukususa i-borehole ngoba isistimu ye-resin ye-TG ephezulu (280°C + [536°F]) ayiguquki kalula phakathi nenqubo yokumba.Uma ibala libangelwa ukubhoboza okunolaka, inhlaka ingasuswa kusetshenziswa umjikelezo we-plasma we-CF4/O2 ojwayelekile noma inqubo ye-alkaline permanganate eyimbili.
Izidingo zokupheka zezinto ezingu-RO4000 ziqhathaniswa nalezo ze-epoxy/glass.Ngokuvamile, amadivaysi angapheki amapuleti e-epoxy/glass awadingi ukupheka ama-RO4003 PCB.Ngokufakwa kwengilazi epoxy/ebhakiwe njengengxenye yenqubo evamile, sincoma ukupheka ku-300°F, 250°F (121°C-149°C) amahora angu-1 ukuya kwangu-2.I-RO4003 ayiqukethe izinqamuleli zomlilo.Ngokuqondakalayo, amapuleti afakwe kumayunithi e-infrared (IR) noma asebenza ngesivinini esiphansi kakhulu sokudlulisa angafinyelela amazinga okushisa angaphezu kuka-700°F (371 °C);I-RO4003 ingaqala ukuvutha kulawa mazinga okushisa aphezulu.Amasistimu asasebenzisa amadivaysi e-infrared reflux noma ezinye izisetshenziswa ezingafinyelela kulawa mazinga okushisa aphezulu kufanele athathe izinyathelo zokuphepha ezidingekayo ukuze aqinisekise ukuthi abukho ubungozi.
I-Ro3003 iyinhlangano yebhodi le-Rogers PCB ye-ceramic egcwele i-PTFE eyinhlanganisela yokuhweba ama-microwave nezicelo ze-RF.Lolu hlu lwemikhiqizo luklanyelwe ukuhlinzeka ngokuzinza okuphakeme kagesi kanye nemishini ngentengo yokuncintisana.I-Rogers Ro3003 inokuqina okuhle kakhulu kwemvume kulo lonke uhla lokushisa, okuhlanganisa ukuqedwa kwezinguquko zemvume ezenzeka lapho izinto zengilazi ze-PTFE zisetshenziswa ekamelweni lokushisa.Ngaphezu kwalokho, ama-laminates e-Ro3003 anama-coefficients okulahlekelwa aphansi njenge-0.0013 kuya ku-10 GHz.
