This week, we updated the circuit board (light and motor control board) for our micro-plate reader, it envolved  diffrent stages: 1. Design and update components on the previous board( the one we used before) and reroute the electric wire on the whole board. 2. update all the files to lichuang EDA ( BOM fule, pick and place file and Gerber file). 3. Order the board online and wait for EDA to manufacture and produce the board. As shown below, we are measuring the length between two female headers( the outlet).
