PCB Breadboard 9 x 7.3cm

green, 1.6mm thick, .95 x 2.54mm holes, solder pads thru double sided.  These are quality boards that I use in my Tube prototype builds.  Note:  Before assembly, prep board by washing in warm soapy water and scrubbing with a 3m blue or scotchbrite type pad, this will ensure good solder adhesion.
