Quite difficult to install but I got there in the end :). I didn't manage to install successfully by drag soldering with a knife tip so I went with the following approach: -Desoldered the dirty NEO-BUF patch with SnBi low melt solder and cleaned up the pads with wick. -Placed the replacement NEO-BUF board down and held in place securely with two strips of kapton tape once aligned. -Soldered all corners with 0.5mm 5core leaded solder and a 0.8mm chisel tip. -Soldered vertically up the trace to the edge pushing solder in to each of the castellated edges. -Removed bridges with 60-2-5 Chemtronics wick and re-soldered these points -Continuity checked each point -Fired up KoF 98 :).
Additional flux seemed to be my enemy in this job!
I'm a big fan of all Furrtek's work, especially these replacement parts, it's great to have someone supporting repair of the original boards. Hopefully there will be a NEO-C1 replacement in future as I have a dead board waiting ;)
Well designed PCB , correct spacing for power traces even if you are sticking a pcb in a USB port. Avoids mis insertion and usb errors. Power circuit for a rechargeable coin Li cell. Pre programmed IC which I didn't expect. Up loadable payload via serial, blasts it at a press of a button.
