Microwave eprintiweyo ibhodi yesekethe kunye ne-RFBFB ifuna ukubanjwa okukhethekileyo abanokuthi bangakwazi ukujongana namaqabane akho okuvelisa rhoqo. Singasebenzisa ii-laminates ezihamba rhoqo ngokuhamba ngokuqinileyo kunye nolawulo lwekhwalithi ephezulu ukuyila ngokufanelekileyo kunye nokuphuhlisa i-PCB yakho ye-RF ukuqinisekisa ukusebenza okuqhelekileyo.

URayming uye waba ngumthengisi ophambili we-RF microwave PCB emhlabeni, egxile kwi-HF PCB laminates. I-Rogers PCB, i-Teflon PCB, i-Arlon PCB, ndinokuvelisa izinto ozifunayo.

I-PCB yePC

< p&gt; Ungathembela kwiimveliso zobungcali zikaRayming kuba sineqela, izixhobo kunye namava okuphatha izinto ezinamathambo ezineemfuno ezizodwa ezinxulumene noomatshini, ubushushu, umbane kunye nezinye izinto ezenziwayo ezingaphaya kwezinto eziqhelekileyo ze-FR-4.

Beka iimveliso zakho kwizandla ezikhuselekileyo ngokuthembela kumthengisi we-rf microwave ophezulu ojolise kwiimfuno ezingqongqo zokunyamezelana kwaye ahambise inkxaso oyifunayo ngexesha, ngalo lonke ixesha.

Qonda ukuba yintoni i-hf PCBS,

1. I-Hf PCBS okanye ubize i-microwave PCBS / i-RF PCBS / i-RF PCBS zisetyenziswa kakhulu kunxibelelwano olungenazingcingo, iinethiwekhi ezingenazingcingo kunye nokunxibelelana ngesathelayithi, ngakumbi uthungelwano lwe-3G, ukwandisa iimfuno zentengiso yeemveliso kwi-HF PCBS. Namhlanje, imfuno yoyilo lweemveliso ze-microwave ze-PCB iyakhula, kwaye ukufikelela kwidatha ngesantya esiphezulu (isantya esiphezulu) sokufikelela kwedatha ngokukhawuleza kuya kuba yimfuneko kwiimarike ezininzi ezinje ngokhuseleko, inqwelo moya kunye nenethiwekhi. Ukutshintsha kweemarike kuyaqhubeka ukuqhuba kuphuhliso lweebhodi eziphezulu zesekethe eziprintiweyo. Njenge-50 + GHz iiradiyo ze-microwave okanye iinkqubo zomoya zokhuselo, inokuthi ikwazi nokufaka ii-PCBS ezingenanto ye-halogen.

2. I-RF yePC kunye Amaza aphakamileyo e-PCBS enziwe nge-polytetrafluoroethylene (PTFE PCB), iiceramic fluoropolymers okanye izinto ze-hydrocarbon ze-thermosetting ezinezinto eziphuculweyo ze-dielectric. Imathiriyeli ine-dielectric ephantsi rhoqo ye-2.0-3.8, ilahleko esezantsi kunye neempawu zokulahleka eziphantsi kakhulu, kodwa ikwanentsebenzo elungileyo, iqondo lobushushu lokutshintsha kweglasi, isantya esisezantsi kakhulu se-hydrophilic, uzinzo olushushu kakhulu. Umlingani wokwandiswa kwezinto ze-PTFE ze-PCB ziyafana nezobhedu, ezenza ukuba izinto zibe nozinzo oluhle kakhulu.

Inkampani yasePanda PCB inyuse izixhobo zokuvelisa kunye notyalo-mali lwe-r & d. Kule minyaka imbalwa idlulileyo kwicandelo lophuhliso lwe-PCB ye-HF, kubathengi abavela kwihlabathi liphela ukuhlangabezana nophuhliso lweemarike ze-RF PCB, sinamava abanzi ekwenziweni kwe-PTFE PCB yeebhodi ezahlukeneyo ze-HF, inokuhamba ngokukhawuleza iye kumzekelo kunye nemveliso yevolumu. Ababoneleli bethu bezinto ze-teflon ngokubanzi babandakanya: I-Rogers PCB, i-Nelco PCB, i-Taconic PCB, i-Arlon PCB.

Isikhokelo ngokubanzi kwiibhodi zesekethe eziprintiweyo

I-RF kunye noyilo lwe-Mircowave PCB

Ii-PCBS zale mihla zidibanisa iintlobo ngeentlobo zethekhnoloji yedijithali kunye nophawu oluxubeneyo, ke ubeko kunye noyilo kuya kuba ngumceli mngeni ngakumbi, ngakumbi xa i-rf kunye ne-microwave zixutywe kumacandelwana. Nokuba usebenza nathi, omnye umthengisi we-RFBB, okanye uyila eyakho i-RFBB yakho, kukho inani lezinto eziqwalaselweyo.

Eyokuqala kukuba uluhlu lwamaxesha e-RF luhlala luyi-500 MHz ukuya kwi-2 GHz, kodwa uyilo olungaphezulu kwe-100 MHz zihlala zithathwa njenge-RF PCBS. Ukuba ungena ngaphaya kwe-2 GHz, ukuluhlu lwee-microwave frequency.

I-RF kunye ne-microwave PCB yoyilo zinomahluko omkhulu-umahluko phakathi kwabo kunye nesekethe yakho esemgangathweni yedijithali okanye ye-analog.

Ngamafutshane, iibhodi zesekethe eziprintiweyo zisebenzisa imiqondiso ye-analog kumaqondo aphezulu kakhulu kwindalo. Isiginali yakho yeRF inokuba phantse kuwo nawuphi na umbane kunye nenqanaba langoku ngalo naliphi na ixesha, ukuba nje iphakathi kobuncinci bomda kunye nobuninzi bemida.

I-RF kunye nee-microwave eziprintiweyo zeebhodi zesekethe ezihambisa imiqondiso kwimo efanayo kunye nakwibhendi ethile yokuhamba rhoqo. Iifilitha zeBandpass zisetyenziselwa ukuthumela imiqondiso kwi “band yenzala” kunye nokucoca naziphi na iimpawu ezingaphandle kwoluhlu lwamaxesha. Ibhendi inokuba mxinwa okanye ibanzi kwaye inokuhanjiswa ngumntu ohamba ngesantya esiphezulu.
