Last time, I introduced how we make sample control panels of sit stand desk. Here I’d like to continue this topic. After soldering work is completed, the internal board will be tested to see if there are any questions.
In the first picture, there are two boards of control keypad. Their buttons got something wrong, so our engineers needed to redo it. She removed the buttons carefully so that it would cause land damage. Then she soldered new buttons to replace the former ones. As you can see, she used tweezers to pick up and fix the button when soldering. The left buttons can’t be used anymore and went to trash bin.
