I'm looking to attach 50 ohms coaxial cable to a circuit board. The signal is only 1kHz. The thought I had is below. Have a pad to solder the braid. Have some space between the braid and center electrode of some insulation and then the center electrode. Maybe for kicks have some drills to run a zip tie through for strain relief. Possibly via stitch the braid pad to the GND layer underneath for added strength.
Are pads like this standardized or am I on my own for this?
