GND solder point won't take the solder - GSM-Forum

ronzinio · 06-11-2013, 11:19

Hi there,

I have a few Wildfire s motherboards where I can solder the other jtag wires (RTCK, TDI etc) with no problems except the GND solder point. I apply flux and apply solder but it does not stick. Is there an alternative GND that you can use?

Thanks

How would that explain the other solder points being soldered correctly?

maybe you need to change another good type of soldering iron

try scratching very gently with the point of exacto / surgical knife then flux and solder....
if that does not work just find another GND on the board.

Hi
You Need Alternative GND?....You can Find In Anywhere in PCB Like Shield or any Resistor(1 Side is GND)
