15 R3, issues replacing network card

I was wondering if anyone had problems removing the existing Killer 1435 WIFI network card. When I started to remove the card I noticed that the black aux antenna line was soldered onto the card. I was able to get it lose and off the card but it took a while to get the solder out of the connector. Once I got the connector cleared of solder I was able to install the Killer 1550 network card with out issues. Who assembles the Alienware laptops because this appears to be a missed QA/QC issue by Dell. I am now worried about other components on the board. This is the second time this year I have run into issues with Dell laptop systems. I took pic and it clearly shows the solder in the connector.
