SMTpads Surface Mount Prototyping Board

SP1-50x50-G SMTpads-Size1, 50x50mil Pads, Unplated Holes, 1/16" Thick

SMTpads is a prototyping circuit board with a grid of pads for 0402, 0603, 0805, 1206, SOT23, and other SMT parts. A grid of 42 mil square pads on 50 mil centers allows SMT components of various sizes and pitches to be mounted. Larger components can span pads. SOIC (50 mil pitch) and DIP (100 mil pitch) integrated circuits can be soldered directly to the pads without adapters. A solid ground plane on the bottom side provides an easy way to make ground connections. There are unplated holes spaced every 500 mils. To make a connection to the ground plane, just insert a wire and solder both sides.

Construction Tip: Solder down one strand of 22 AWG stranded wire to make tracks where you need them. Use solid 22 AWG wire for higher current power and ground tracks.


  • Square SMT pads on 0.050" centers for surface mount components
  • Double-sided high-quality FR4 glass-epoxy circuit board with unplated holes
  • 1 oz/ft² copper with anti-tarnish coating for easy soldering. Lead free and RoHS compatible
  • 0.031" (0.79 mm) holes (unplated) for connections to ground plane. Just insert a wire and solder
  • Four 0.125" mounting holes
  • Size: 50 x 80mm (1.97 x 3.15 in), 1/16" thick (1.6 mm)
