* Press the red seal onto the microstrip line surface and solder the tab.
* Tab Soldering Conditions
Soldering iron tip temperature: 260 to 290ç
Time: Within 5 seconds
* Note that althrough the high frequency characteristics will be somewhat degraded, please attach the tab with some
slack in order to improve the thermal reliability.
