Kachiwiri, womenyera Mount Protegetor ali ndi mawonekedwe abwino. Amatha kudzipatula bwino kufalitsa ndi kulandira zizindikiro, kupewa zosokoneza, ndipo samalani ndi chizindikiro. Kukula kwa ntchito yowoneka bwinoyi kungatsimikizire kuti dongosololi ndi kuchepetsa kusokonekera.
Kuphatikiza apo, womenyera Mount Mount Mount Mount, alinso ndi kutentha kwambiri. Amatha kugwira ntchito pamtunda wotentha, nthawi zambiri kumangofika kutentha kuyambira -40 ° C kwa + 85 ° C, kapena ngakhale zonse. Kutentha kumeneku kumathandizira kuti wozungulira azigwiritsa ntchito modalirika m'malo osiyanasiyana.
Njira yoyendetsera phiri la SMD pamwamba pa malo ozungulira amawapangitsanso kukhala osavuta kuphatikiza ndikukhazikitsa. Amatha kukhazikitsa zida zozungulira pa PCB kudzera muukadaulo wokwera, popanda kufunikira kwa chikhalidwe cha pini kapena njira zogulitsira. Njira yaphiri iyi sikuti imangowonjezera mphamvu yopanga, komanso imathandizira kuphatikizidwa kwapamwamba, potero kupulumutsa madera ndi kusinthasintha kwa dongosolo.
Kuphatikiza apo, Spdom Photo lozungulira lili ndi ntchito zambiri zolumikizirana pafupipafupi machitidwe ndi zida zama microwave. Zitha kugwiritsidwa ntchito podzipatula pakati pa rf amplifars ndi antennas, kukonza dongosolo ndi kukhazikika. Kuphatikiza apo, Spdom Protelators imatha kugwiritsidwanso ntchito zida zopanda zingwe, kulumikizana kopanda zingwe, makina a radiar, ndi kulumikizana kwa satellite, kuti akwaniritse zosowa za kudzipatula kwabwino kwambiri komanso kuwonongeka.
Mwachidule, womenyera Phiri la Mougetor ndi wopaka, wopepuka, komanso wosavuta kukhazikitsa chida chowoneka bwino ndi chowonjezera cha batiren, komanso kukhazikika kwabwino, ndi kukhazikika kwa kutentha. Ali ndi ntchito zofunika kwambiri monga zitsanzo zolankhulirana kwambiri ndi ma microwave pafupipafupi, zida za microwave, ndi zida za wailesi. Ndi chitukuko chopitilira muukadaulo, chosasungunuka chozungulira mozungulira chidzatenga mbali yofunika kwambiri m'minda yambiri ndikuthandizira pakukula kwaukadaulo wamakono.
A RF Pamwamba Phiri Lonse (RF SMT) Ndi mtundu wapadera wa RF yomwe imagwiritsidwa ntchito poyendetsa ndikuwongolera mawonekedwe a RF. Mfundo yake yogwira ntchito imakhazikitsidwa pa kusintha kwa Faraday Phenomena ndi maginito odziwika bwino mu elekitomicnetics. Gawo lalikulu la chipangizochi ndikuloleza zizindikiro mu mbali inayake kuti idutse kwinaku.
Chigawo cha RF SMT chimakhala ndi madoko atatu, chilichonse chomwe chingalowe kapena zotulutsa kapena zotulutsa. Chizindikiro chikalowa padoko, chimapita ku doko lina kenako ndikutuluka padoko lachitatu. Malangizo a kutuluka kwa chizindikirocho nthawi zambiri amakhala otchinga. Ngati zoyesera zikwangwani zofalikira mosayembekezereka, kuzungulira kwa chilengedwe kumatchinga kapena kuyamwa chizindikiro kuti musasokonezedwe ndi mbali zina za dongosolo kuchokera ku chizindikiro chosinthira.
Ubwino waukulu wa ma blet a rf smt ndi akuluakulu komanso kuphatikiza kwakukulu. Chifukwa cha kugwiritsa ntchito ukadaulo wa Phiri la Mount Mount, Crideotor iyi ikhoza kukhazikitsidwa mwachindunji pa bolodi la madera osafunikira mawaya owonjezera kapena zolumikizira. Izi sizimangochepetsa kuchuluka ndi kulemera kwa zida, komanso zimapangitsa kuyikapo ndi kukonza. Kuphatikiza apo, chifukwa cha kapangidwe kake kophatikizidwa, rf smt smilators kumakhala ndi luso komanso kudalirika.
Pamapulogalamu othandiza, ozungulira a RF SMT amatenga mbali yofunika kwambiri mu ma rf. Mwachitsanzo, m'dongosolo la rad Pakanema ozozolowera, itha kugwiritsidwa ntchito kupatula kutsatsa ndikulandila antennas kuti ilepheretse wolandila mwachindunji. Kuphatikiza apo, chifukwa chophatikizidwa kwake komanso kuphatikizika kwakukulu, gawo lozungulira la RF SMT limagwiritsidwanso ntchito kwambiri m'minda monga magalimoto osayatsidwa ndi ma satellite.
Komabe, kupanga ndi kupanga ndi ma blatilators rf smt kumakhalanso ndi zovuta zina. Choyamba, monga mfundo yake yogwirira ntchito yamagetsi yamagetsi, kupanga ndi kutsatsa ndi njira yoyendera yoyambira. Kachiwiri, chifukwa chogwiritsa ntchito ukadaulo wa Phiri la Mount Mount, njira zopangidwa ndi gawo la Wellhutor imafunikira zida zapamwamba komanso zowongolera. Pomaliza, pamene doko lirilonse la machilengedwe liyenera kulongosola molondola mwapang'onopang'ono, kuyezetsa ndi kuwononga madera ozungulira kumafunikiranso ukadaulo waluso.
