Ovaviu bilong Prodak
Model bilong SMA meri PCB konekta em SMA-KE SMT.SMA series em ol 50 ohms RF konekta we planti manmeri i save yusim, we i gat wanpela 'threaded interface', na i save givim gutpela na gutpela wok bilong pawa long ol bikpela frikwensi. Ol i save yusim planti long 'aero' na 'aero space', ol samting bilong pait bilong ami, ol 'wireless network', na ol 'microwave devices' o 'data communication'. Ol i save pasim tu ol 'semi-flex' o 'semi-rigid kebol we i wok inap long 18GHz.
SMA Konekta i go long PCB Koneksen Rot
1. Dairekt Plug Koneksen
Stretpela Posisen na Insersen : Stretim 'direct plug SMA plug' wantaim ol hul bilong putim long PCB we ol i bin wokim pinis. Putim isi isi na isi isi, na meksua olsem olgeta wan wan pin bilong plug i stret wantaim hul bilong putim. Noken putim bikpela strong tumas taim yu putim insait bilong en long abrusim ol 'plug pin' o bagarapim ol hul bilong putim long PCB.
Securely Secure the Pins: Yusim ol 'tweezers' long bendim gut ol 'plug pins' liklik bai ol i ken pas gut long PCB. Dispela i mekim na 'plug' i stap gut na i no inap muv taim yu 'solder', na dispela i mekim na 'solder' i kamap gutpela.
Precise Soldering: Hatim solder iron i go long 300 digri -350 digri. Putim liklik 'flux' long 'contact point' namel long 'pin' na 'PCB'. Bihain, yusim 'solder wick' long 'solder' pin i go long PCB pad. Taim yu wok long solder, yu mas bosim gut taim na tempereja, na holim wanwan pin i solder inap 2-3 seken long stopim ol kol solder join, sot seket, o bagarap long PCB bikos long bikpela tempereja o solder i stap longpela taim. Bihain long solder i pinis, katim ol 'pin' i stap yet gut wantaim ol 'wire cutter'.
2. Koneksen bilong putim antap long graun
Pasin bilong hatim na solderim: Ol SMA konekta we ol i putim antap long graun i mas solderim insait long wanpela 'reflow oven'. Tempereja bilong 'preheat' i mas stap namel long 150 digri na 200 digri long mekim 'solder' i melt gut na kamapim gutpela koneksen. Noken hat tumas taim yu solderim bilong stopim bagarap long konekta o PCB.
