Product Overview
Imodeli ye-SMA female connector PCB yi-SMA-KE SMT.SMA uthotho zidumile 50 ohms iziqhagamshelo RF, usebenzisa ujongano olunemisonto, ebonelela ngokuthembekileyo nokusebenza kombane okugqwesileyo kwiifrikhwensi eziphezulu. Zisetyenziswa kakhulu kwindawo ye-aero kunye ne-aero, izixhobo zomkhosi, inethiwekhi engenazingcingo, kunye nezixhobo ze-microwave okanye unxibelelwano lwedatha. Bakwancamathela phakathi-iintambo ezithambileyo okanye eziphakathi{6}}eziqinileyo ezisebenza ukuya kuthi ga kwi-18GHz.
Isidibanisi se-SMA kwiiNdlela zoQhagamshelwano lwePCB
1. UQhagamshelwano lwePlagi eNgqo
Ukuma nokuFaka okuchanekileyo: Lungelelanisa iplagi ethe ngqo ye-SMA iplagi kunye{0}}nemingxuma efakelweyo eyilwe ngaphambili kwi-PCB. Faka ngobunono kwaye ngokucothayo, uqinisekise ukuba isikhonkwane ngasinye seplagi silungelelaniswe ngokuchanekileyo nomngxuma wokuxhoma. Kuphephe ukusebenzisa amandla agqithisileyo ngexesha lofakelo ukunqanda ukugoba izikhonkwane zeplagi okanye ukonakalisa imingxuma enyukayo kwi-PCB.
Khusela izikhonkwane ngokukhuselekileyo: Sebenzisa i-tweezers ukugoba ngononophelo izikhonkwane zeplagi kancinane ukuze zilingane kakuhle kwi-PCB. Oku kuqinisekisa ukuba iplagi ihlala izinzile kwaye inqanda nayiphi na intshukumo ngexesha le-soldering, iqinisekisa umgangatho ophezulu{1} wenkqubo yokubethela.
I-Soldering echanekileyo: Preheat intsimbi ye-solder ukuya kwi-300℃-350 degree. Faka inani elincinci lokuhamba kwindawo yoqhagamshelwano phakathi kwephini kunye nePCB. Emva koko, sebenzisa i-solder wick ukuthengisa i-pin kwi-PCB pad. Ngexesha le-soldering, lawula ngokungqongqo ixesha kunye nobushushu, ugcine i-pin nganye i-solder imizuzwana emi-2-3 ukunqanda i-solder ebandayo, iisekethe ezimfutshane, okanye umonakalo kwi-PCB ngenxa yokushisa okugqithisileyo okanye ixesha elide. Emva kokuba i-soldering igqityiwe, nquma naziphi na izikhonkwane ezingaphezulu ngobunono ngeengcingo zokusika.
2. UQhagamshelwano lweNtaba yoMphezulu
Ukushisa kwangaphambili kunye neSoldering: Umphezulu wokunyuka kwe-SMA iziqhagamshelo zifuna i-soldering kwi-oven yokubuyisela. Ukushisa kwe-preheat kufuneka kulawulwe phakathi kwe-150 kunye ne-200℃ukuqinisekisa ukuba i-solder iyanyibilika ngokupheleleyo kwaye yenza uxhulumaniso oluhle. Kuphephe ukutshisa kakhulu ngexesha le-soldering ukuthintela umonakalo kwikhonkco okanye kwiPCB.
