[Elecraft] K2 LCD issue

[Don Wilhelm]

"inspecting the solder joints" ---  what to look for ---
What you should look for is on the component side of the board.  On a 
proper solder connection for boards with thru-plated holes, you should 
see some solder on the component lead that has flowed through the hole.

If there was not enough heat applied or the soldering dwell time was too 
short, the solder will not wick through the hole and even though the 
solder side looks to be OK, the component side will tell you if the 
solder connection is complete.

That is important for those components whose leads barely go through the 
board.  It is easy to get solder over the entire solder pad, and still 
have no good solder connection to the component lead.
