[Elecraft] Thermistor board

[Jeremiah McCarthy]

When building the thermistor board for the K2, you will notice that the thermistor board does not have plate-thru holes...The solder bond between the board foil and the wire lead is on the surface of the board only, not through the board to the other side...One should leave a small raised fillet of solder at these connections...If they are clipped off flush with the board, there is a chance that the bond between the wire and the solder pad has been cut off...Been there, done that...After the wires are soldered into the thermistor board and bent over, try swiveling them from side to side...If they swivel, you have a bad joint...
