Product Overview
Modhi yeSMA yechikadzi PCB yekubatanidza ndeye SMA-KE SMT.SMA dzakatevedzana dzakakurumbira 50 ohms RF zvibatanidza, zvichishandisa chinongedzo chine threaded, chinopa yakavimbika uye yakanakisa kushanda kwemagetsi muma frequency epamusoro. Iwo anoshandiswa zvakanyanya munzvimbo yeaero uye aero, zvombo zvemauto, isina waya network, uye microwave zvishandiso kana data kutaurirana. Vanoisawo semi-flex kana semi-tambo dzakaoma dzinoshanda kusvika ku18GHz.
SMA Connector kuPCB Connection Nzira
1. Yakananga Plug Connection
Precise Positioning and Insertion Pinza zvinyoro nyoro uye zvishoma nezvishoma, uchive nechokwadi chekuti pini yega yega yeplug yakanyatsoenderana negomba rekukwira. Dzivisa kushandisa simba rakawandisa panguva yekuisa kudzivirira kupeta mapini epuragi kana kukuvadza maburi ekukwira paPCB.
Chengetedza Mapini: Shandisa tweezers kunyatsokotamisa mapini eplug zvishoma kuti akwane paPCB. Izvi zvinoita kuti plug irambe yakagadzikana uye kudzivirira chero kufamba panguva yekusodha, zvichiita-mhando yepamusoro yekusodha.
Precise Soldering: Preheat the soldering iron kusvika 300℃-350 degree. Isa diki diki yekuyerera kune yekuonana nzvimbo pakati pepini nePCB. Zvadaro, shandisa solder wick kutengesa pini kuPCB pad. Panguva yekutengesa, nyatso chengetedza nguva uye tembiricha, uchichengeta pini yega yega inotengeswa kwemasekonzi 2-3 kudzivirira majoini anotonhora ekutengesa, mapfupi maseketi, kana kukuvadzwa kwePCB nekuda kwekunyanya kupisa kana kurebesa soldering. Mushure mekunge soldering yapera, cheka chero mapini akawandisa zvakanaka newaya cutters.
2. Surface Mount Connection
Preheating uye Soldering: Surface gomo SMA majoini anoda soldering muhovhoni inoyerera. Iyo preheat tembiricha inofanirwa kudzorwa pakati pe150 dhigirii uye 200 dhigirii kuti ive nechokwadi chekuti solder inonyungudika zvizere uye inogadzira kubatana kwakanaka. Dzivisa kupisa panguva yekutengesa kudzivirira kukuvara kune chinongedzo kana PCB.
