Worked well for a hard to solder BNC connector
5 out of 5 stars
Worked well for a hard to solder BNC connector
I had problems getting the solder to wet the terminals on a Molex BNC connector. I assumed it was a heat issue, but after melting the insulation on a couple connectors, I tried this flux. It worked very well, as you can see in the photo. Keep in mind that it's always a good idea to shop around for the best price.
