How do dry joints work?
-
Or how do they not work? Recently I had a problem with 19" Acer LCD where 1/4 of the screen dissappeared at the bottom. (I mean dissapeared no distortion) When the blonde took it to the purchasing shop it worked for them, then it worked back at her office. Two days later the whole screen disapeared. We got them to replace it and have had no problems since. The tech head said it must be a dry joint. What does that mean ? (No MJ jokes please) :-) Regardz Colin J Davies The most LinkedIn CPian (that I know of anyhow) :-)

I believe it means the solder didn't set properly, and as it warms up, the connection is lost. Christian Graus - Microsoft MVP - C++

Actually its when a leg of a component goes through the PCB and does not get soldered. This causes the two components to only make a connection due to them touching each other. As a PCB flexes and warms up etc, this can cause the components to move and thus break the connection between them. Also, they can be affected by vibration. If you vote me down, my score will only get lower
