SMA hmeichhe PCB connector model chu SMA-KE SMT a ni.SMA series hi 50 ohms RF connector lar tak a ni a, threaded interface hmangin, frequency sang takah electrical performance rintlak leh tha tak a pe a ni. Aero leh aero space, sipai ralthuam, wireless network, leh microwave device ordata communication-ah te an hmang nasa hle. Tin, semi-flex emaw semi-rigid cable 18GHz thlenga thawk thei an dah bawk.
SMA Connector atanga PCB inzawmna siam dan
1. Direct Plug hmanga inzawmna
Precise Positioning and Insertion : Direct plug SMA plug chu PCB-a mounting holes ruahman lawk nen align rawh. Zawi zawiin leh zawi zawiin dah la, plug pin tin chu mounting hole nen a inmil tawk tih enfiah rawh. Plug pin te bend loh nan emaw PCB-a mounting holes te tihchhiat loh nan insertion laiin force tam lutuk hmang lo la.
Pins te chu him taka secure : Tweezer hmangin plug pin te chu PCB-a a in fit tha theih nan uluk takin tlem tal bend rawh. Hei hian plug chu a nghet reng a, soldering laiin engmah a che thei lo a, soldering process quality sang tak-quality a tichiang a ni.
Precise Soldering : Soldering iron chu 300℃-350℃ah dah hmasa phawt ang che . Pin leh PCB inkar contact point-ah flux tlem te te dah la. Tichuan, solder wick hmangin pin chu PCB pad-ah solder rawh. Soldering lai hian a hun leh a lumna kha khauh takin control la, pin tin chu second 2-3 chhung soldering-ah dah la, chutiang chuan cold solder joint, short circuit, emaw temperature lutuk emaw soldering rei tak avanga PCB a chhiat loh nan. Soldering zawh hnuah pin tam lutuk chu wire cutter hmangin uluk takin trim tur a ni.
2. Surface Mount hmanga inzawmna
Preheating leh Soldering: Surface mount SMA connector te hi reflow oven ah soldering a ngai a. Solder chu a hmin kim theih nan leh connection tha tak a siam theih nan preheat temperature chu 150℃leh 200℃inkar ah control tur a ni. Soldering laiin a lum lutuk loh nan connector emaw PCB emaw a chhiat loh nan.
