This product utilizes the "EZ" technology to assure fast, easy, and flawless hand soldering Ground holes are connected a copper plane on the bottom side.
This board was supposed to have "EZ" technology but came back from the factory without "EZ" or with less "EZ" than our Q/A would accept. They were rejected by us for this reason. For someone who can solder surface mount without the help of "EZ", these boards are a bargain. There are no returns on these boards, all sales are final.
