Kodi ma board ozungulira okhazikika angagwiritsidwe ntchito pamapulogalamu a RF?

M'dziko lomwe likukula mwachangu lamagetsi, luso komanso kusinthasintha ndizofunikira kwambiri kuti mukhale patsogolo pa mpikisano. Kugwiritsa ntchito ma radio frequency (RF) ndi gawo lomwe likukula kwambiri. Kuchokera pamakina olumikizirana opanda zingwe kupita kuukadaulo wa satana ndi makina a radar, kugwiritsa ntchito kwa RF kumagwira ntchito yofunikira. Kuti akwaniritse zosowa za mapulogalamuwa, mainjiniya ndi opanga amafufuza njira zatsopano.Njira imodzi yotchuka ndiyo kugwiritsa ntchito ma rigid flex circuit board. Koma kodi ma board ozungulira okhazikika angagwiritsidwe ntchito pamapulogalamu a RF? Mu blog iyi, tisanthula nkhaniyi mwatsatanetsatane.

Ma board ozungulira okhwima ndi osakanizidwa a matabwa olimba komanso osinthika. Amaphatikiza zabwino kwambiri zamitundu yonseyi, zomwe zimawapanga kukhala abwino pakupanga zovuta zamagetsi.Magawo olimba amapereka kukhazikika komanso chithandizo chamapangidwe, pomwe magawo osinthika amalola kupindika ndi kupindika, kuwalola kulowa mumipata yothina. Kuphatikizika kwapadera kumeneku kumapangitsa matabwa olimba-osinthika kukhala oyenera kugwiritsa ntchito zosiyanasiyana, kuphatikiza ma frequency a wailesi.

Mapulogalamu a RF amafunikira kufalitsa koyenera komanso kolondola kwa ma siginecha apamwamba kwambiri. Kusokoneza kulikonse kapena kutayika kwa mtundu wa siginecha kumasokoneza magwiridwe antchito.Ma board ozungulira olimba-flex amapereka kukhulupirika kwazizindikiro chifukwa cha kutayika kwawo kochepa. Zida za dielectric zomwe zimagwiritsidwa ntchito pomanga zimakhala ndi zinthu zochepa zowonongeka, zomwe zimawonetsetsa kuchepetsedwa kwa chizindikiro. Izi ndizofunikira kwambiri pamapulogalamu a RF pomwe mphamvu yama siginecha imagwira ntchito yofunika kwambiri.

Ubwino wina wama board ozungulira okhazikika pamapulogalamu a RF ndikutha kuchepetsa kusokoneza kwamagetsi (EMI) ndi kusokoneza kwa ma radio frequency (RFI).Magawo osinthika a matabwawa amakhala ngati zishango, zomwe zimalepheretsa kusokoneza kwakunja kukhudza chizindikirocho. Katundu wotchinjiriza uyu ndiwopindulitsa makamaka pamakina a RF omwe amafunikira chidwi komanso kulondola kwambiri.

Kuphatikiza apo, mapangidwe apadera a ma rigid-flex circuit board amalola kuwongolera moyenera milingo ya impedance. Kufananiza kwa Impedans ndikofunikira pamapulogalamu a RF kuti awonetsetse kufalikira kwamphamvu komanso kupewa zowunikira.Ma board a Rigid-flex amapatsa mainjiniya kusinthasintha kuti apange magawo angapo a impedance pa bolodi limodzi, kuchotseratu kufunikira kwa zida zowonjezera kapena njira zolumikizira zovuta.

Ma board ozungulira olimba-flex amapereka maubwino angapo potengera malingaliro opanga. Mapangidwe ake ophatikizika amasunga malo ndikuchepetsa kufunika kwa zolumikizira ndi zingwe, kufewetsa dongosolo lonse la dongosolo.Kuphatikiza apo, kuchotsa zolumikizira kumachepetsa chiopsezo cha kutayika kwa chizindikiro ndikuwonjezera kudalirika. Izi ndizofunikira makamaka pamapulogalamu a RF omwe amafunikira kutumizira ma sigino osasinthasintha.

Ndizofunikira kudziwa kuti kukhazikitsidwa bwino kwa ma board ozungulira okhazikika pamapulogalamu a RF kumafuna kusamala komanso kusanja.Kukonzekera koyenera, kutsata njira, ndi kuyika ma siginecha ndizofunikira kwambiri kuti magwiridwe antchito akwaniritse bwino. Kugwirizana pakati pa mainjiniya, opanga, ndi opanga ndikofunikira kuti zitsimikizidwe kuti mapangidwe akwaniritsidwa komanso kuti chomaliza chikukwaniritsa miyezo ya RF.

Powombetsa mkota

Ma board ozungulira olimba amatha kugwiritsidwa ntchito pamapulogalamu a RF. Kuphatikizika kwawo kwapadera kwa kuuma ndi kusinthasintha, kuphatikizira ndi zotsika zotsika komanso chitetezo cha EMI/RFI, zimawapangitsa kukhala njira yabwino. Ndi kuthekera kwawo kuwongolera ndendende milingo ya impedance ndi zabwino zake zopangira, ma board olimba-flex amapereka yankho lodalirika pamakina a RF.

Komabe, ndikofunikira kutsindika kufunikira kwa mapangidwe oyenera ndi mgwirizano pakati pa onse okhudzidwa. Kusamala mwatsatanetsatane pakupanga ndi kupanga ndikofunikira kuti RF igwire bwino ntchito. Ndi njira yoyenera, ma board ozungulira okhazikika amatha kupereka kudalirika, kuchita bwino komanso magwiridwe antchito ofunikira pamapulogalamu osiyanasiyana a RF, zomwe zimathandizira kukulirakulira kosalekeza kwa kulumikizana opanda zingwe ndi ukadaulo.
