The Tough Board series. This is a large, general purpose breadboard useful for an expanded layout. We provide 4,131 isolated pads for component placement plus 4 board mounting holes. The substrate is durable FR4 material with a Tg-170 rating and 2oz copper each side. The 2oz copper top and bottom dramatically improves soldering durability and improved current handling vs. 1oz copper. The top pads are round, and the bottom pads are square to accommodate soldering a variety of discrete SMD components. This 6×9 size is useful as a backplane accommodating multiple daughter boards.
