Thepa ea Rogers RO4350B e lumella lienjineri tsa RF PCB ho rala lipotoloho habonolo, joalo ka ho tsamaisa marang-rang le taolo ea ho sitisa mehala ea phetisetso.Ka lebaka la litšobotsi tsa eona tse tlase tsa tahlehelo ea dielectric, thepa ea RO4350B e na le molemo o ke keng oa bapisoa ho feta lisebelisoa tse tloaelehileng tsa potoloho lits'ebetsong tse phahameng tsa maqhubu.Phapang ea tumello ka mocheso e batla e le tlase ka ho fetisisa har'a lisebelisoa tse tšoanang, 'me tumello ea eona e boetse e tsitsitse ka mefuta e mengata ea maqhubu, ka tlhahiso ea moralo oa 3.66.LoPra™ Copper foil e fokotsa tahlehelo ea ho kenya.Sena se etsa hore thepa e loketse lits'ebetso tsa Broadband.

Rogers PCB board: thepa ceramic high frequency PCB letoto la lihlopha:

RO3000 letoto: PTFE thepa ea potoloho e thehiloeng ho tlatsoa ka ceramic, mehlala ke: RO3003, RO3006, RO3010, RO3035 high-frequency laminate.

Letoto la RT6000: le ipapisitse le thepa ea potoloho ea ceramic e tlatsitsoeng ea PTFE, e etselitsoeng lipotoloho tsa elektroniki le li-circuits tsa microwave tse hlokang tumello e phahameng.Mehlala ke: tumello ea RT6006 6.15, tumello ea RT6010 10.2.

Letoto la TMM: lisebelisoa tse kopantsoeng tse thehiloeng holim'a ceramic, hydrocarbon, thermosetting polymer, mohlala: TMM3, TMM4, TMM6, TMM10, TMM10i, TMM13i., joalo-joalo.
Thepa ea RO4003 e ka tlosoa ka borashe bo tloaelehileng ba nylon.Ha ho na ho tšoara e khethehileng e hlokahalang pele electroplating koporo ntle le motlakase.Letlapa le tlameha ho phekoloa ka mokhoa o tloaelehileng oa epoxy / khalase.Ka kakaretso, ha ho hlokahale ho tlosa borehole hobane tsamaiso e phahameng ea TG resin (280 ° C + [536 ° F]) ha e fetole mebala habonolo nakong ea ho cheka.Haeba letheba le bakoa ke ts'ebetso e matla ea ho phunya, resin e ka tlosoa ho sebelisoa potoloho ea plasma e tloaelehileng ea CF4/ O2 kapa ka ts'ebetso e habeli ea alkaline permanganate.

Litlhoko tsa ho pheha tsa thepa ea RO4000 li bapisoa le tsa epoxy / khalase.Ka kakaretso, lisebelisoa tse sa pheheng lipoleiti tsa epoxy / khalase ha li hloke ho pheha RO4003 PCBs.Bakeng sa ho kenya khalase ea epoxy / e besitsoeng e le karolo ea mokhoa o tloaelehileng, re khothalletsa ho pheha ka 300 ° F, 250 ° F (121 ° C-149 ° C) bakeng sa lihora tse 1 ho isa ho tse peli.RO4003 ha e na lintho tse thibelang malakabe.Ka ho utloahalang, lipoleiti tse kentsoeng ka li-unit tsa infrared (IR) kapa tse sebetsang ka lebelo le tlase haholo la phetisetso li ka fihlela mocheso o fetang 700°F (371 °C);RO4003 e ka qala ho tuka ka mocheso ona o phahameng.Litsamaiso tse ntseng li sebelisa lisebelisoa tsa infrared reflux kapa lisebelisoa tse ling tse ka fihlelang mocheso ona o phahameng li lokela ho nka mehato e hlokahalang ho netefatsa hore ha ho na kotsi.

Ro3003 ke Rogers PCB board material ceramic e tletseng PTFE composite bakeng sa li-microwave tsa khoebo le lits'ebetso tsa RF.Mefuta ena ea lihlahisoa e etselitsoe ho fana ka botsitso bo phahameng ba motlakase le mechine ka theko ea tlhōlisano.Rogers Ro3003 e na le botsitso bo botle ba tumello holim'a mocheso oohle oa mocheso, ho kenyelletsa le ho felisoa ha liphetoho tsa tumello tse etsahalang ha lisebelisoa tsa khalase tsa PTFE li sebelisoa mocheso oa kamore.Ho feta moo, li-laminate tsa Ro3003 li na le li-coefficients tsa tahlehelo tse tlase ho 0.0013 ho isa ho 10 GHz.
