The Tough Board series. This is a compact, general purpose, .100” grid breadboard, useful for taking your design from schematic to hardware. The substrate is a rugged FR4 with a Tg-170 rating and 2 ounce copper rings and square pads for soldering durability and current handling  The square pads on the bottom will accommodate several sizes of discrete SMD placement. This model has no traces between holes ( isolated pads ) which gives you the maximum flexibility to experiment with your layout. In addition to the 397 pads, there are 4, .250″ diameter mounting holes.
