Rf and microwave PCB Sele iminyaka eliqela kwaye ixhaphake kakhulu kushishino lwe-elektroniki. Zidume kakhulu kwaye ziyilelwe ukusebenza ngemiqondiso kwi-MHZ ukuya kwi-gigahertz yokuhamba rhoqo. Ezi PCBS zilungile xa kuziwa kuthungelwano kunye nokusetyenziswa konxibelelwano. Zininzi izizathu zokuba kutheni abavelisi be-PCB bancomela i-RF kunye neebhodi ze-microwave zokufaka izicelo zonxibelelwano. Ngaba uyafuna ukwazi ukuba zintoni? Eli nqaku lixoxa ngomcimbi omnye.

Amagqabantshintshi e-RF kunye ne-microwave PCB

Ngokwesiqhelo, iRF kunye neebhodi zemicrowave ziyilelwe ukusetyenziswa embindini ukuya kuthi ga kwinqanaba eliphezulu okanye ngaphezulu kwe-100 MHz. Ezi bhodi zinzima ukuyilwa ngenxa yobunzima bolawulo obuqala kwimvakalelo yokulawula ulawulo lweempawu zokudlulisa ubushushu. Nangona kunjalo, obu bunzima abukunciphisi ukubaluleka kwabo. Ukusetyenziswa kwemathiriyeli eneepropathi ezinje nge-dielectric engagungqiyo, umlinganiso ophezulu wokwanda kwe-thermal (CTE) kunye nelahleko ephantsi ye-Angle tangent inceda ukwenza lula inkqubo yokwakha. Izinto zePCB zihlala zisetyenziselwa ukwakha iRF kunye neePCA zemicrowave ziihydrocarbon ezigcwaliswe ngodongwe, PTFE ngemicu ephothiweyo okanye encinci, FEP, LCP, Rogers RO laminates, ukusebenza okuphezulu kwe-FR-4, njl.

Izibonelelo ezahlukeneyo zeRF kunye neePCB zemicrowave

I-Rf kunye ne-microwave PCBS zibonelela ngeenzuzo ezininzi eziluncedo. Ke makhe sijonge kubo bonke.

Iimathiriyeli ezine-CTE ezisezantsi zinceda izakhiwo zePCB zihlala zizinzile kumaqondo obushushu aphezulu. Ngapha koko, ezi zinto zenza ukuba ii-multilayers zilungelelaniswe lula.

Ngenxa yokusetyenziswa kwezinto ze-CTE ezisezantsi, iinjineli zePCB zinokulungelelanisa ngokulula iipleyiti ezininzi kwizakhiwo ezintsonkothileyo.

Iindleko zendibano yeRF kunye neePCB zemicrowave zinokuncitshiswa kulungelelwaniso lomfumba oluninzi. Esi sakhiwo sikwanegalelo ekusebenzeni kwePCB ngokugqibeleleyo.

U-Er ozinzileyo kunye nelahleko esezantsi yokuququzelela ukuhambisa ngokukhawuleza kweempawu ezihamba rhoqo ngezi PCBS. Ngapha koko, i-impedance iphantsi ngexesha lokuhambisa.

Iinjineli ze-PCB zinokubeka iindawo ezifanelekileyo ze-pitch ngokufanelekileyo ebhodini, enceda ukufezekisa uyilo oluntsonkothileyo.

Ke ngoko, ezi zibonelelo zenza i-RF kunye ne-microwave PCBS ezilungeleyo kwizicelo ezahlukeneyo kubandakanya ukuhanjiswa okungenazingcingo kunye nezinye iinkqubo zonxibelelwano zekhompyuter.
