七天线设计，密集恐惧症
遇上歪脖子天线 
Sorry for that. This job is done by JLCPCB. I advised them to apply more solder to the SMA connectors to make them stronger. I think there may be more than one operator doing the soldering job, since there are thousands of boards to be soldered. Quality may vary across boards depending on the operators’ soldering skills. I should check them carefully before I ship them.
