12V 7.2AH SLA battery (7): UC2906 charger PCB version 2

 I have revised the board layout from the previous post in this series (6) to use surface mount parts and use a 2 sided board. I also added a small prototype area consisting of a grid of 2.54mm spaced holes.   This will aid in bringing up the board.  I've ordered the board from PBCWAY.   See the diagrams below. 

I bought a bottle of ferric chloride etchant and I've been studying how to make two sided boards on Youtube videos.  I will try to make my own two sided PC Board.
